Final Cut Pro + DaVinci Resolve

The concept of offline and online editing goes back to the origins of film editing. Work print was cut by the film editor during the creative stage of the process and then original negative was conformed by the lab and married to the final mix for the release prints (with a few steps in between). The terms offline and online were lifted from early computer lingo and applied to edit systems when the post process shifted from film to video. Thus offline equates to the creative editorial stage, while conforming and finishing services are defined as online.

Digital nonlinear edit systems evolved to become capable of handling all of these stages of creative editorial and finishing at the highest quality level. However, both phases require different mindsets and skills, as well as more advanced hardware for finishing. And so, the offline/online split continues to this day.

If you are an editor cutting local market spots, YouTube videos, corporate marketing pieces, etc, then you are probably used to performing all of these tasks on your own. However, most major commercials, TV shows, and films definitely split them up. In feature films and high-end TV shows, the film editors are separate from the sound editing/mixing team and everything goes through the funnel of a post facility that handles the finishing services. The latter is often referred to as the DI (digital intermediate) process in feature film productions.

You may be cutting on Media Composer, Premiere Pro, or Final Cut Pro, but the final assembly, insertion of effects, and color correction will likely be done with a totally different system and/or application. The world of finishing offers many options, like SGO Mistika, Quantel Rio, and Filmlight Baselight. But the tools that pop up most often are Autodesk Flame, DaVinci Resolve, and Avid Symphony (the latter for unscripted shows). And of course, Pro Tools seemingly “owns” the audio post market.

Since offline/online still exists, how can you use modern tools to your advantage?

If Apple’s Final Cut Pro is your main axe, then you might be reading this and think that you can easily do this all within FCP. Likewise, if you’ve shifted to Resolve, you’re probably wondering, why not just do it all in Resolve? Both concepts are true in theory; however, I contend that most good editors aren’t the best finishers and vice versa. In addition, it’s my opinion that Final Cut is optimized for editing, whereas Resolve is optimized for finishing. That doesn’t make them mutually exclusive. In fact, the opposite is true. They work great in tandem and I would suggest that it’s good to know and use both.

Scenario 1: If you edit with FCP, but use outside services for color and sound, then you’ll need to exchange lists and media. Typically this means AAF for sound and FCPXML for Resolve color (or possibly XML or AAF if it’s a different system). If those systems don’t accept FCPXML lists, then normally you’d need to invest in tools from Intelligent Assistance and/or Marquis Broadcast. However, you can also use Resolve to convert the FCPXML list into other formats.

If they are using Resolve for color and you have your own copy of Resolve or Resolve Studio, then simply import the FCPXML from Final Cut. You can now perform a “preflight check” on your sequence to make sure everything translated correctly from Final Cut. Take this opportunity to correct any issues before it goes to the colorist. Resolve includes media management to copy and collect all original media used in your timeline. You have the option to trim files if these are long clips. Ideally, the DP recorded short takes without a lot of resets, which makes it easy to copy the full-length clip. Since you are not rendering/exporting color-corrected media, you aren’t affected by the UHD export limit of the free Resolve version.

After media management, export the Resolve timeline file. Both media and timeline file can go directly to the colorist without any interpretation required at the other end. Finally, Resolve also enables AAF exports for audio, if you need to send the audio files to a mixer using Pro Tools.

Scenario 2: What if you are doing everything on your own and not sending the project to a colorist or mixer for finishing? Well, if you have the skillset and understand the delivery criteria, then Resolve is absolutely your friend for finishing the project. For one thing, owning Resolve means you could skip purchasing Apple Motion, Compressor, and/or Logic Pro, if you want to. These are all good tools to have and a real deal from a cost standpoint; however, Resolve or Resolve Studio definitely covers most of what you would do with these applications.

Start the same way by sending your FCPXML into Resolve. Correct any editorial issues, flatten/collapse compound and multicam clips, etc. Insert effects and titles or build them in the Fusion page. Color correct. When it comes to sound, the Fairlight page is a full-fledged DAW. Assuming you have the mixing chops, then Fairlight is a solid stand-in for Logic Pro, Pro Tools, or other DAWs. Finally, export the various formats via the Deliver page.

Aside from the obvious color and mixing superiority of Resolve over Final Cut Pro, remember that you can media-manage, as well as render out trimmed clips – something that FCP won’t do without third-party applications. It’s also possible to develop proxy workflows that work between these two applications.

While both Final Cut Pro and DaVinci Resolve are capable of standing alone to cover the creative and finishing stages of editing, the combination of the two offers the best of all worlds – a fast editing tool and a world-class finishing application.

Could Fairlight be your next DAW?

When I review audio plug-ins and software, it’s from my perspective as a video editor. I’m not a recording engineer or mixer; however, I do dabble with music mixes as a hobbyist and to improve my audio chops. As such, I occasionally delve into digital audio workstation software, such as Sound Forge, Audio Design Desk, and others. My favorite is Apple Logic Pro, but as a DaVinci Resolve and Adobe user, I also have Fairlight (part of Resolve) and Adobe Audition. I touched on the Fairlight page in some detail as part of my Resolve Studio 18 review, but in this post I want to focus on it purely from the perspective of a DAW user on music projects.

Blackmagic’s reimagining

When Blackmagic Design acquired the assets of Fairlight, the software was refreshed and developed into the Fairlight page within DaVinci Resolve. Even though it’s nested inside of a video editing and grading tool, Fairlight is capable of being a standalone audio application. No need to ever have video enter into the equation.

Fairlight is integrated into both DaVinci Resolve (free) and Resolve Studio ($295). The Studio version can be activated on two computers at the same time. Nearly all Fairlight features and effects are the same in both versions, with the exception of ATMOS and spatial audio mixing/monitoring, which requires the Studio version. If your only interest is stereo recording and mixing, then Resolve is one of the only, truly free DAWs on the market. No significant feature restrictions and no Blackmagic hardware required. Plus, it works in Windows, Linux, and macOS.

Along with this software development, Blackmagic Design has expanded the ecosystem of companion Fairlight products. These include an accelerator card, a modular chassis, control surfaces, controllers, and an audio interface. The Fairlight page also supports Blackmagic’s two editor keyboards. You can run Fairlight without any external hardware, yet it’s scalable up to a complete recording studio rig. On a Mac, any Core Audio device will do, so recording into Fairlight and monitoring the output is compatible with simple USB audio interfaces, like Focusrite, PreSonus and others.

Understanding the interface

The Fairlight interface is compatible with single and dual-display set-ups and uses UI panels that can be turned on and off or slid onto the screen as needed. You can show or hide individual pieces of the mixer, as well. Unfortunately in a single display system, like an iMac, you cannot display the mixer panel full-screen. A project with 20 to 30 or more source tracks, requires left to right scrolling. However, since the 18.1 update, the meter bridge panel allows for two rows of meters.

The mixer uses a channel strip format for each track, which includes input/output/send routing, effects, and a built-in parametric equalizer and compressor. This is much like the channel strip of a traditional analog studio console, like an SSL or Neve. Unlike some other DAWs, you can also change the signal order of effects, EQ, and dynamics (compression) within each channel strip.

Modern plug-ins

Resolve includes Fairlight FX audio plug-ins that cover most common needs. But since this software is targeted towards the film and TV customer, it doesn’t include music-centric plug-ins, like the guitar amp and pedal emulations offered in Logic Pro. That focus is true of the plug-in presets, as well. For example, the factory preset choices in the compressor will be for dialogue and not musical instruments, like a drum kit or guitar. That doesn’t mean you can’t do music with these plug-ins. Presets are just suggestions anyway, so you should tweak based on what sounds right to you.

Fairlight does not color the sound. The sonic character, interface, and plug-in design take a clean, modern approach. There are no vintage options and none of the plug-ins are designed as skeuomorphic emulations of studio gear synonymous with classic recordings from the 70s. After all, film re-recording mixers have never been particularly precious about certain consoles or outboard gear from ages ago. Other than maybe a love for old Nagras, I doubt there’s much fondness for old audio gear like mag dubbers. At least not in the same way that music recording engineers still like to use analog recorders in the signal chain.

If you do want vintage tools, then Fairlight supports third-party AU and VST plug-ins. However, as with other video applications, I’ve found that some of the skeuomorphic effects don’t always work or look right. For example, I often use the free VU meter from TBProAudio. In Fairlight, only the AU version will appear as intended. And if you own an M1 or M2 Mac, then double-check that your favorite third-party plug-in is natively supported.

Fairlight isn’t just for audio post

Avid’s Pro Tools is the 800-pound gorilla. But, many Pro Tools users are often frustrated with the cost of staying current and dealing with Avid as a company. While such concerns may or may not be justified, Pro Tools isn’t the only game in town. Unless you need to interchange Pro Tools projects, there are plenty of alternatives. And that’s where Fairlight comes in. First of all, if audio post for film and TV is your primary focus, then Fairlight is up to the task. Resolve will import XML, FCPXML, and AAF files for both color and sound finishing. Fairlight includes an ADR recording routine, a free sound effects library, and a foley sampler plug-in. But let me focus on Fairlight as a music DAW.

I started with multitracks of song covers available from Warren Huart’s “Produce Like A Pro” YouTube channel. I didn’t record my own tracks, other than to test how recording might work. I’m a big believer that a great mix is achieved by doing 90% of the work at the time of the studio recording. It’s not about building the sound through plug-ins and tricks, but getting the right blend of gear, mics, and performance from the players. That was already there in the multitracks, so the mix was more about the right balance of these elements.

Achieving a successful mix

Fairlight works with as many tracks and busses as are created in your timeline. My standard layout for mixing is to use summing busses. You can create as many as you need. The 35 tracks for this song include drums, percussion, bass, piano, electric and acoustic guitars. I route each set of instrument tracks to a buss dedicated to that group, even if there’s only one instrument track in that group. These six busses are then routed to a submix buss, which in turn is routed to the master buss for output. This allows for gain staging and quickly balancing  levels. The default Fairlight layout automatically routes the first buss (drums in my case) as the output to the speakers and on the Deliver page. Be sure to change each of these to your master buss for the proper intended output.

My goal was to come out with a result that hit desired loudness targets and sounded good to me, mainly using the stock plug-ins. You’re going to adjust levels, but most of the effects center around EQ, compression, and reverb. Each of these is adequately covered by the complement of Fairlight FX. If you have singers, then there are also vocal processing effects, like de-essing. However, an investment in iZotope RX is certainly a useful add-on. For example, RX includes a specific tool to remove or reduce guitar squeaks and string noise. The Resolve 18.1 update added many audio-centric features, including a new voice isolation feature. It works well for any vocal situation and in my opinion has fewer negative artifacts than most of the competing options.

In my test mix, I adjusted level, panning, EQ, and compression on each channel strip. At the buss level, I added more EQ and compression, plus some reverb. The last stage was a multiband compressor and a brick wall limiter on the submix buss. Only meter plug-ins were added to the master buss. Of course, Fairlight includes its own useful set of meters for level and loudness.

Fairlight is actually quite good for music production, editing, and mixing. Since it’s built into an NLE, the project supports multiple mixes. You can have bins and timelines to organize the tracks and mixes for various different songs, as well as different versions of each mix. Resolve 18 added new cloud collaboration tools, however, you can easily collaborate on mixes by exporting a timeline file to send to a colleague. Assuming the other system has access to the same audio files and third-party plug-ins (if used), then it’s simply a matter of importing that timeline file.

Processing for this number of tracks and effects was easily handled by my iMac. It could have handled more, including more intense third-party plug-ins, like Gullfoss, Ozone, FabFilter, or Sonible. If you really need to go BIG, then Blackmagic Design promises up to 2,000 real-time tracks for the full Fairlight hardware installation! So if Pro Tools isn’t in the cards for you, then look over Fairlight and Resolve. It might just be right for your music mixing needs.

Additional thoughts

Some of the comments I received on the PVC version of this article (see link below) pointed out that Fairlight does not include such music-centric tools as MIDI and a piano roll, like some other DAWs do. While this is true, these are tools used by music creators working with synthetic instruments, like software samples for guitar, strings, drums, etc. That’s not a universal requirement, especially if you record and mix live performers using real instruments. Certainly if you need those specialized features, then other DAWs are a better fit for you.

It’s important to remember that digital audio workstation (DAW) software is used for a wide variety of audio production tasks. Such productions are often recorded and edited with tools that do not include some of these music features either. For example, Adobe Audition is widely used in the production of podcasts and radio commercials. So while Fairlight might not fit all needs, there’s little harm in trying a free application and then seeing where that leads.

Want to try mixing in Fairlight for yourself, but don’t have the tracks? Check out these 50 free, downloadable multitrack song sets from Warren Huart. I’ve only scratched the surface, so be sure to check out Blackmagic’s Fairlight training series.

NLE Tips – Proxy Hacks

Editors often think of the clip within the edit application’s browser as the media file. But that clip is only a facsimile of the actual media. It links to potentially three different assets on the hard drive – the original camera (or sound) file, optimized media, and/or proxy media.

Optimized media. You may decide to create optimized media when the original media’s codec or file format is too taxing on your system. For example, you might convert a media file made up of an image sequence into an optimized movie file using one of the ProRes or DNx codecs. When you create optimized media, that is often the media used for finishing instead of the original camera media. For sake of simplicity I’ll refer to original media from here on, but understand that it could be optimized media or original camera files.

Proxy media. There are many reasons for creating proxy media – portability, system performance, remote editing, etc. Proxy media is usually lightweight, more highly compressed, and of a lower resolution than the original media. Nearly all editing applications enable users to edit with lightweight proxy media in lieu of heavier, native camera files. When proxy media has been created, then the media clip in the NLE’s browser can actually link to both the original camera file, as well as the proxy media file. Software “toggles” in the application can seamlessly swap the link from one type of media file to the other.

The NLEs that offer proxy editing workflows integrate routines to transcode and automatically switch the links between proxy and original camera files on the hard drive. DaVinci Resolve 18 is the newest in this group with the addition of the Blackmagic Proxy Generator application. However, that tool only works with Resolve Studio 18 downloaded from Blackmagic Design’s website. The Generator is an addition to Resolve 18 and augments the built-in transcoding tools. In either case, you don’t have to use the built-in routines nor the Blackmagic Proxy Generator. You can encode proxies using different software and even different computers. Then you can attach those proxies to the clips in the editing application at a later time.

Creating external proxy media

Proxies can be created with any encoding software. I like Apple Compressor, which includes a category of presets specifically designed for proxy media generation. The presets can be modified according to your needs.  For instance, you can add a LUT and effects, like a timecode overlay. This makes it easy to know when you are toggled to the original or the proxy media within the NLE.

Before creating any proxy files, make sure that your original files all have unique file names. Rename any duplicates or those with generic file names, like Clip001, Clip002, etc. There are several key parameters needed for successful relinking between original and proxy media. These include matching names, frame rates, timecode, lengths, and audio channel configurations. Some applications let you force a relink when some of these items don’t match, but it will usually be one file at a time.

Frame sizes can be smaller, since that’s an aspect of any proxy workflow. For example, if you start with 4K/UHD original media, but you create half-size HD proxies. The embedded metadata in the proxy file informs the NLE so that the correct size is maintained when switching between the two. Likewise, the codecs do not need to match. You can have 4K/UHD ProRes HQ originals and HD H.264 proxy media (I prefer ProRes Proxy). The point is to have proxy media with smaller file sizes, which play back more efficiently on your computer.

When you transcode proxy media files in Compressor or any other encoding application, it’s best to render them into a folder specifically called Proxy. This can be anywhere you like, but it’s best to have it near your original camera files. If you have multiple camera file folders – organized by camera roll, day, camera model, etc – then there are two options. You can either have one single Proxy file for all renders or have a separate subfolder called Proxy within each camera roll folder.

Dealing with externally-created proxies in different editing applications

Final Cut Pro – There is a setting to switch between Proxy Preferred and Original/Optimized. When you create external proxies, highlight the original camera clips and relink to the proxy media in the Proxy folder(s). Once proxies have been linked, then you can seamlessly switch between the two types of media.

Premiere Pro – There is a similar toggle button accessible in the timeline tools panel. The linking steps are similar to Final Cut Pro. Highlight the originals and then Attach Proxies. Navigate to the Proxy folder(s) and attach that media. The toggle button lets you switch back and forth between media types.

DaVinci Resolve Studio 18 – This update changed the proxy workflow as well as added the Generator application. You can still use the older proxy generation method. If so, then set the encoding parameters and location in your project settings. If you encode using the Blackmagic Proxy Generator app or an external application, then it’s a different process. The advantage to using Blackmagic Proxy Generator is that you can set up watch folders for automatic encoding.

The default location when using the Blackmagic Proxy Generator app or Resolve’s internal routine places a Proxy subfolder inside the folder of each roll of original media. When that condition exists, then original clips added into the Media page automatically include links to both the original and the proxy media. In fact, the Proxy subfolders don’t even show up in Resolve’s browser when searching for media. When both types of media are present, then the Resolve clip icons reflects that duality.

When you transcode externally with Compressor or another app, then media placed into individual Proxy subfolders will also automatically link inside Resolve. However, if you render to a single, unified Proxy folder, then you’ll need to manually relink the proxy files to the originals in the Media page. Like the other two NLEs, you can do this as a batch function by navigating to the Proxy folder.

I hope these pointers will be a useful guide the next time you decide to use a proxy media workflow.

DaVinci Resolve Speed Editor

Since the beginning of nonlinear editing, developers and accessory providers have added custom keyboards and controllers that emulated the film and videotape systems they replaced. Avid had the MUI, Lightworks used a flatbed-style controller, and Contour Design offers the ShuttlePRO. In 2019 Blackmagic Design launched DaVinci Resolve 16 along with a companion DaVinci Resolve Editor Keyboard. Its design is reminiscent of CMX or Sony keyboards used in high-end linear edit suites.

The larger keyboard was followed by a smaller edition dubbed the DaVinci Resolve Speed Editor. This controller is close to what you might have seen in a linear ENG edit bay with someone cutting news packages on two Sony BVU-800 3/4″ decks. The Editor Keyboard is designed to work Resolve’s cut and edit pages, but the Speed Editor is primarily for the cut page. However, the transport controls work with all the pages and mark and trim commands operate on the edit page, as well.

Speed Editor retails for $395 and includes a license key for DaVinci Resolve Studio. It operates over Bluetooth, but firmware updates and charging require a USB-C connection. It will pair with Resolve (version 17 or 18), but not other apps nor the Finder. Although you can perform much of the cut page editing operation from Speed Editor, it won’t entirely replace your keyboard and mouse or trackpad. The design is right-handed, but since you can place it to the left or in front of an external keyboard, it’s easier for a left-hander to utilize than the QWERTY-style Editor Keyboard.

The main selling point for me is the knob, aka the Search Dial. As with the Editor Keyboard dial, it has a similar tactile feel and the ballistics of using a Sony tape machine. Of course, you are dealing with files not tape, so it can easily stop on a dime. There’s shuttle, jog, and scroll control. Shuttle locks in the speed and is best for moving through lots of material. I found myself mainly using scroll and jog. If you use it on the Fairlight page, then jog emulates the analog tape experience of “reel rocking” to find an exact edit point. For me, the quality of the Search Dial experience surpasses any of the other Eucon or USB peripherals.

Cut page

You can’t review Speed Editor without giving some coverage to the cut page itself. This is an alternative editing model introduced with DaVinci Resolve 16. At a casual glance, the design and operation is like a mash-up of Final Cut Pro and LumaFusion.

The cut page design is optimized for fast editing. I applaud that effort, which is largely successful. However, the waters are muddied with Sync Bin – an alternate multicam editing method. In my opinion, the edit page is a far better tool for multicam projects. Quite frankly, the software development that Blackmagic put into this, as well as the real estate taken up in the Speed Editor keypad for multicam, should have been applied in other ways, like mappable function keys.

Another design issue I have, is that the cut page nomenclature and editing tasks are inconsistent with the edit page. For example, there is no traditional Insert or Overwrite command and no Delete (lift) – only Ripple Delete (extract). Ripple Overwrite is actually a replace function and Source Overwrite is tied to the alternate way of editing multicam projects. All clips are assembled as interleaved video/audio clips; however, you can’t trim audio and video separately on those clips to create L-cuts and J-cuts.

I could continue, as there are other missing features that I believe are essential for any editor. But let me dive into Speed Editor and explain how you can use it and the cut page to your advantage.

Fast editing

Speed Editor works best when you use it for fast assembly in the cut page. Buttons are grouped according to function. (Read about the specific details in the DaVinci Resolve manual, Chapter 49). When starting from a fresh timeline, it’s best to first select the Source button and Append clips to the timeline. The raw footage is presented in the Source Tape mode. Clips are organized chronologically into a virtual timeline that you can shuttle, scroll, or play through. In other words, Resolve has automatically arranged the clips into a stringout making it easy to find the relevant shots. The Source Tape mode is much faster than hover scrubbing over individual clips. It is unique to Resolve and reproduces the fluid experience of cutting with two VTRs.

Once the initial assembly is done, click the Timeline key and go through your sequence to trim shots or roll edit points. There are single buttons to add dissolves, wipes, and smooth cuts (morph transitions). The timeline is track-based, so press the Place On Top key to add picture cutaways and additional audio. Any clip with video is edited to a higher track, while an audio-only clip is placed onto a lower audio track.

The Speed Editor commands are intelligent operations. For instance, if you select Trim Out to adjust a clip’s out point, the playhead will automatically select the edit point closest to the playhead – either before or after the playhead position. Then move the Search Dial to adjust the trim amount and the rest of the timeline reacts magnetically. Likewise, the Smart Insert command will insert a source clip at the nearest cut, rather than the playhead position. But, there are no “go to in (or out)” or “top” and “tail” edit commands.

If you need to punch into a shot, click the Close-Up button. This places a copy of that clip in sync at the playhead position onto a higher track and scales it larger. Many of the keypad buttons have secondary functions printed on the edge of the key. You can access these with a double-click or click-and-hold. The Close-Up key also enables a position change on the Y-axis. Hold the key and tilt the shot up or down by turning the Search Dial. Unfortunately, you cannot pan the shot on the X-axis nor change the scale value.

Conclusion

Who is the ideal user for the cut page and the Speed Editor? And, has nonlinear editing really gone beyond these types of peripherals? To the first question, I presume Blackmagic Design sees these tools as something that would appeal to beginning editors, ENG editors, and maybe YouTube content creators. When it comes to Speed Editor, you still need to use the mouse and keyboard for certain functions. If so, then is this device necessary? That’s harder to answer, because the Search Dial functions are so good and addictive. While I can do much of the same with a Magic Mouse, there are plenty of editors with repetitive stress issues in their hands and wrists for whom Speed Editor could become an essential tool.

Controllers designed to mimic flatbed or linear tape editing may be a false goal for developers. Modern NLE interfaces are simply more complex. I wish Blackmagic Design had enabled custom mapping for Speed Editor just like a regular keyboard. That’s a lost opportunity that hopefully can be fixed in a future update.

Modern editing is often done on laptops and that’s a sweet spot for Speed Editor. You’ve still got a built-in keyboard and trackpad when you need it, but a lot of the standard editing tasks can be done with a task-appropriate tool. If Resolve is your main NLE, then the small, lightweight Speed Editor is a good companion for powerhouse laptops like Apple’s M1 MacBook Pros.

Colourlab Ai

An artificial intelligence grading option for editors and colorists

There are many low-cost software options for color correction and grading, but getting a stunning look is still down to the skill of a colorist. Why can’t modern artificial intelligence tools improve the color grading process? Colorist and color scientist Dado Valentic developed Colourlab Ai as just that solution. It’s a macOS product that’s a combination of a standalone application and companion plug-ins for Resolve, Premiere Pro, Final Cut Pro, and Pomfort Live Grade.

Colourlab Ai is comprised of two main functions – grading and show look creation. Most Premiere Pro and Final Cut Pro editors will be interested in either the basic Colourlab Ai Creator or the richer features of Colourlab Ai Pro. The Creator version offers all of the color matching and grading tools, plus links to Final Cut Pro and Premiere Pro. The Pro version adds advanced show look design, DaVinci Resolve and Pomfort Live Grade integration, SDI output, and Tangent panel support. These integrations differ slightly, due to the architecture of each host application.

Advanced color science and image processing

Colourlab Ai uses color management similar to Resolve or Baselight. The incoming clip is processed with an IDT (input device transform), color adjustments are applied within a working color space, and then it’s processed with an ODT (output device transform) – all in real-time. This enables support for a variety of cameras with different color science models (such as ARRI Log-C) and it allows for output based on different display color spaces, such as Rec 709, P3, or sRGB.

If you prefer to work directly with the Colourlab Ai application by itself – no problem. Import raw footage, color correct the clips, and then export rendered movie files with a baked in look. Or you can use the familiar roundtrip approach as you would with DaVinci Resolve. However, the difference in the Colourlab Ai roundtrip is that only color information moves back to the editing application without the need to render any new media.

The Colourlab Ai plug-in for Final Cut Pro or Premiere Pro reads the color information created by the Colourlab Ai application from an XML file used to transfer that data. A source effect is automatically applied to each clip with those color parameters. The settings are still editable inside Final Cut Pro (not Premiere Pro). If you want to modify any color parameter, simply uncheck the “Use Smart Match” button and adjust the sliders in the inspector. In fact, the Colourlab Ai plug-in for FCP is a full-featured grading effect and you could use it that way. Of course, that’s doing it the hard way!

The ability to hand off source clips to Final Cut Pro with color metadata attached is unique to Colourlab Ai. This is especially a game changer for DITs who deliver footage with a one-light grade to editors working in FCP. The fact that no media need be rendered also significantly speeds up the process.

A professional grading workflow with Final Cut Pro and Colourlab Ai

Thanks to Apple’s color science and media architecture, Final Cut Pro can be used as a professional color grading platform with the right third-party tools. CoreMelt (Chromatic) and Color Trix (Color Finale) are two examples of developers who have had success offering advanced tools, using floating panels within the Final Cut Pro interface. Colourlab Ai takes a different approach by offloading the grade to its own application, which has been designed specifically for this task.

My workflow test involved two passes – once for dailies (such as a one-light grade performed by a DIT on-set) and then again for the final grade of the locked cut. I could have simply sent the locked cut once to Colourlab Ai, but my intention was to test a workflow more common for feature films. Shot matching between different set-ups and camera types is the most time-consuming part of color grading. Colourlab Ai is intended to make that process more efficient by employing artificial intelligence.

Step one of the workflow is to assemble a stringout of all of your raw footage into a new FCP project (sequence). Then drag that project from FCP to the Colourlab Ai icon on the dock (Colourlab Ai has already been opened). The Colourlab Ai app will automatically determine some of the camera sources (like ARRI files) and apply the correct IDT. For any unknown camera, manually test the settings for different cameras or simply stick with a default Rec 709 IDT.

The Pro interface features three tabs – Grade, Timeline Intelligence, and Look Design. The top half of the Grade tab displays the viewer and reference images used for matching. Color wheels, printer light controls, scopes, and versions are in the bottom half. Scope choices include waveform, RGB parade, or vectorscope, but also EL Zones. Developed by Ed Lachman, ASC, the EL Zone System is a false color display with 15 colors to represent a 15-stop exposure range. The mid-point equates to the 18% grey standard.

AI-based shot matching forms the core

Colourlab Ai focuses on smart shot matching, either through its Auto-Color feature or by matching to a reference image. The application includes a variety of reference images, but you can also import your own, such as from Shotdeck. The big advance Colourlab Ai offers over other matching solutions is Color Tune. A small panel of thumbnails can be opened for any clip. Adjust correction parameters – brightness, contrast, density, etc – simply by stepping through incremental value changes. Click on a thumbnail to preview it in the viewer.

The truly unique aspect is that Color Tune lets you choose from eleven matching options. Maybe instead of a Smart model, you’d prefer to match based only on Balance or RGB or a Perceptual model. Step through the thumbnails and pick the look that’s right for the shot. Therefore, matching isn’t an opaque process. It can be optimized in a style more akin to adjusting photos than traditional video color correction.

Timeline Intelligence allows you to rearrange the sequence to group similar set-ups together. Once you do this, use matching to set a pleasing look for one shot. Select that shot as a “fingerprint.” Then select the rest of the shots in a group and match those to the fingerprinted reference shot. This automatically applies that grade to the rest. But, it’s not like adding a simple LUT to a clip or copy-and-pasting settings. Each shot is separately analyzed and matched based on the differences within each shot.

When you’re done going through all of the shots, right-click any clip and “push” the scene (the timeline) back to Final Cut Pro. This action uses FCPXML data to send the dailies clips back to Final Cut, now with the added Colourlab Ai effect containing the color parameters on each source clip.

Remember that Final Cut Pro automatically adds a LUT to certain camera clips, such as ARRI Alexa files recorded in Log-C. When your clips comes back in from Colourlab Ai, FCP may add a LUT on top of some camera files. You don’t want this, because Colourlab Ai has already made this adjustment with its IDT. If that happens, simply change the inspector LUT setting for that source file to “none.”

Lock the edit and create your final look

At this point you can edit with native camera clips that have a primary grade applied to them. No proxy media rendered by a DIT, hence a much faster turnaround and no extra media to take up drive space. Once you’ve locked the edit, it’s time for step two – the show look design for the final edit.

Drag the edited FCP project (new sequence with the graded clips) to the Colourlab Ai icon on the dock to send the edited sequence back to Colourlab Ai. All of the clips retain the color settings created earlier in the dailies grading session. However, this primary grade is just color metadata and can be altered. After any additional color tweaks, it’s time to move to Show Looks. Click through the show look examples and apply the one that fits best.

If you have multiple shots with the same look, apply a show look to the first one, copy it, and then apply that look to the rest of the selected clips. In most cases, you’ll have a different show look for various scenes within a film, but it’s also possible that a single show look would work through the entire film. So, experiment!

To modify a look or create your own, step into the Look Design tab (Pro version). Here you’ll find the Filmlab and Primary panels. Filmlab uses film stock emulation models and film’s subtractive color (CMY instead of RGB) for adjustments. Their film emulation is among the most convincing I’ve seen. You can select from a wide range of branded negative and print film stocks and then make contrast, saturation, and CMY color adjustments. The Primary panel gives you even more control over RGBCMY for the lift, gamma, and gain regions. Custom adjustments may be saved to create your own show looks. Once you’ve set a show look for all of your shots, push the sequence back to Final Cut Pro. Voila – a fully graded show and no superfluous media created in the process.

Some observations

Colourlab Ai is a revolutionary tool based on a film-style approach to grading. Artificial intelligence models speed up the process, but you are always in control. Thanks to the ease of operation, you can get great results without Resolve’s complex node structure. You can always augment a shot with FCP’s own color tools for a power window or a vignette.

The application currently lacks a traditional undo/redo stack. Therefore, use the version history to experiment with settings and looks. Each time you generate a new match, such as with Auto-Color or using a reference image, a new version is automatically stored. If you want to iterate, then manually add a version at any waypoint if a new match isn’t involved – for example, when making color wheels adjustments. The version history displays a thumbnail for each version. Step through them to pick the one that suits you best.

If you are new to color correction, then Colourlab Ai might look daunting at first glance. Nevertheless, it’s deceptively easy to use. There are numerous tutorials available on the website, as well as directly accessible from the launch window. A 7-day free trial can be downloaded for you to dip your toes in the water. The artificial intelligence at the heart of Colourlab Ai will enable any editor to deliver professional grades.
