Peter Jackson’s The Hobbit: An Unexpected Journey was one of the most anticipated films of 2012. It broke new technological boundaries and presented many creative challenges to its editor. After working as a television editor, Jabez Olssen started his own odyssey with Jackson in 2000 as an assistant editor and operator on The Lord of the Rings trilogy. After assisting again on King Kong, he next cut Jackson’s Lovely Bones as the first feature film on which he was the sole editor. The director tapped Olssen again for The Hobbit trilogy, where unlike the Rings trilogy, he will be the sole editor on all three films.
Much like the Rings films, all production for the three Hobbit films was shoot in a single eighteen month stretch. Jackson employed as many as 60 RED Digital Cinema EPIC cameras rigged for stereoscopic acquisition at 48fps – double the standard rate of traditional feature photography. Olssen was editing the first film in parallel with the principal photography phase. He had a very tight schedule that only allowed about five months after the production wrapped to lock the cut and get the film ready for release.
To get The Hobbit out on such an aggressive schedule, Olssen leaned hard on a post production infrastructure built around Avid’s technology, including 13 Media Composers (10 with Nitris DX hardware) and an ISIS 7000 with 128TB of storage. Peter Jackson’s production facilities are located in Wellington, New Zealand, where active fibre channel connections tie Stone Street Studio, Weta Digital, Park Road Post Production and the cutting rooms to the Avid ISIS storage. The three films combined, total 2200 hours (1100 x two eyes) of footage, which is the equivalent of 24 million feet of film. In addition, an Apace active backup solution with 72TB of storage was also installed, which could immediately switch over if ISIS failed.
The editorial team – headed up by first assistant editor Dan Best – consisted of eight assistant editors, including three visual effects editors. According to Olssen, “We mimicked a similar pipeline to a film project. Think of the RED camera .r3d media files as a digital negative. Peter’s facility, Park Road Post Production, functioned as the digital lab. They took the RED media from the set and generated one-light, color-corrected dailies for the editors. 24fps 2D DNxHD36 files were created by dropping every second frame from the files of one ‘eye’ of a stereo recording. For example, we used 24fps timecode with the difference between the 48fps frames being a period instead of a colon. Frame A would be 11.22.21.13 and frame B would be 11:22:21:13. This was a very natural solution for editing and a lot like working with single-field media files on interlaced television projects. The DNxHD files were then delivered to the assistant editors, who synced, subclipped and organized clips into the Avid projects. Since we were all on ISIS shared storage, once they were done, I could access the bins and the footage was ready to edit, even if I were on set. For me, working with RED files was no different than a standard film production.”
Olssen continued, “A big change for the team since the Rings movies is that the Avid systems have become more portable. Plus the fibre channel connection to ISIS allows us to run much longer distances. This enabled me to have a mobile cart on the set with a portable Media Composer system connected to the ISIS storage in the main editing building. In addition, we also had a camper van outfitted as a more comfortable mobile editing room with its own Media Composer; we called it the EMC – ‘Editorial Mobile Command’. So, I could cut on set while Peter was shooting, using the cart and, as needed, use the EMC for some quick screening of edits during a break in production. I was also on location around New Zealand for three months and during that time I cut on a laptop with mirrored media on external drives.”
The main editing room was set up with a full-blown Nitris DX system connected to a 103” plasma screen for Jackson. The original plan was to cut in 2D and then periodically consolidate scenes to conform a stereo version for screening in the Media Composer suite. Instead they took a different approach. Olssen explained, “We didn’t have enough storage to have all three films’ worth of footage loaded as stereo media, but Peter was comfortable cutting the film in 2D. This was equally important, since more theaters displayed this version of the film. Every few weeks, Park Road Post Production would conform a 48fps stereo version so we could screen the cut. They used an SGO Mistika system for the DI, because it could handle the frame rate and had very good stereo adjustment tools. Although you often have to tweak the cuts after you see the film in a stereo screening, I found we had to do far less of that than I’d expected. We were cognizant of stereo-related concerns during editing. It also helped that we could judge a cut straight from the Avid on the 103” plasma, instead of relying on a small TV screen.”
The editorial team was working with what amounted to 24fps high-definition proxy files for stereo 48fps RED .r3d camera masters. Edit decision lists were shared with Weta Digital and Park Road Post Production for visual effects, conform and digital intermediate color correction/finishing at a 2K resolution. Based on these EDLs, each unit would retrieve the specific footage needed from the camera masters, which had been archived onto LTO data tape.
The Hobbit trilogy is a heavy visual effects production, which had Olssen tapping into the Media Composer toolkit. Olssen said, “We started with a lot of low resolution, pre-visualization animations as placeholders for the effects shots. As the real effects started coming in, we would replace the pre-vis footage with the correct effects shots. With the Gollum scenes we were lucky enough to have Andy Serkis in the actual live action footage from set, so they were easy to visualize how the scene would look. But other CG characters, like Azog, were captured separately on a Performance Capture stage. That meant we had to layer separately-shot material into a single shot. We were cutting vertically in the timeline, as well as horizontally. In the early stages, many of the scenes were a patchwork of live action and pre-vis, so I used PIP effects to overlay elements to determine the scene timing. Naturally, I had to do a lot of temp green-screen composites. The dwarves are full-size actors and for many of the scenes, we had to scale them down and reposition them in the shot so we could see how the shots were coming together.”
As with most feature film editors, Jabez Olssen likes to fill out his cut with temporary sound effects and music, so that in-progress screenings feel like a complete film. He continued, “We were lucky to use some of Howard Shore’s music from the Rings films for character themes that tie The Hobbit back into The Lord of the Rings. He wrote some nice ‘Hobbity’ music for those. We couldn’t use too much of it, though, because it was so familiar to us! The sound department at Park Road Post Production uses Avid Pro Tools systems. They also have a Media Composer connected to the same ISIS storage, which enabled the sound editors to screen the cut there. From it, they generated QuickTime files for picture reference and audio files so the sound editors could work locally on their own Pro Tools workstations.”
Audiences are looking forward to the next two films in the series, which means the adventure continues for Jabez Olssen. On such a long term production many editors would be reluctant to update software, but not this time. Olssen concluded, “I actually like to upgrade, because I look forward to the new features. Although, I usually wait a few weeks until everyone knows it’s safe. We ended up on version 6.0 at the end of the first film and are on 6.5 now. Other nonlinear editing software packages are more designed for one-man bands, but Media Composer is really the only software that works for a huge visual effects film. You can’t underestimate how valuable it is to have all of the assistant editors be able to open the same projects and bins. The stability and reliability is the best. It means that we can deliver challenging films like The Hobbit trilogy on a tight post production schedule and know the system won’t let us down.”

I recently spoke with Kirk Baxter and Angus Wall, who as a team have cut Fincher’s last three films, earning them a best editing Oscar for The Social Network as well as a nomination 
The key to efficient post on a RED project is the workflow. Assistant editor Tyler Nelson explained the process to me. “We used essentially the same procedures as for The Social Network. Of course, we learned things on that, which we refined for this film. Since they used both the RED M-X and the EPIC cameras, there were two different frame sizes to deal with – 4352 x 2176 for the RED One and 5120 x 2560 for the EPIC. Plus each of these cameras uses a different color science to process the data from the sensor. The file handling was done through Datalab, a company that Angus owns. A custom piece of software called Wrangler automates the handling of the RED files. It takes care of copying, verifying and archiving the .r3d files to LTO and transcoding the media for the editors, as well as for review on the secured PIX system. The larger RED files were scaled down to 1920 x 1080 ProRes LT with a center-cut extraction for the editors, as well as 720p H.264 for PIX. The ‘look’ was established on set, so none of the RED color metadata was changed during this process.”
The Girl with the Dragon Tattoo leans heavily on a score by 
I definitely enjoyed the Oscar-winning treatment these two editors applied to intercutting dialogue scenes in The Social Network, but Baxter was quick to interject, “I’d have to say Dragon Tattoo was more complicated than The Social Network. It was a more complex narrative, so there were more opportunities to play with scene order. In the first act you are following the two main characters on separate paths. We played with how their scenes were intercut so that their stories were as interconnected as possible, giving promise to the audience of their inevitable union.”
Ever since the launch of 
The 4K discussion starts at sensor size. Camera manufacturers have adopted larger sensors to emulate the look of film for characteristics such as resolution, optics and dynamic range. Although different sensors may be of a similar physical dimension, they don’t all use the same number of pixels. A RED EPIC and a Canon 7D use similarly sized sensors, but the resulting pixels are quite different. Three measurements come into play: the actual dimensions, the maximum area of light-receiving pixels (photosites) and the actual output size of recorded frames. One manufacturer might use fewer, but larger photosites, while another might use more pixels of a smaller size that are more densely packed. There is a very loose correlation between actual pixel size, resolution and sensitivity. Larger pixels yield more stops and smaller pixels give you more resolution, but that’s not an absolute. RED has shown with EPIC that it is possible to have both.
The biggest visual attraction to large-sensor cameras appears to be the optical characteristics they offer – namely a shallower depth of field (DoF). Depth of field is a function of aperture and focal length. Larger sensors don’t inherently create shallow depth of field and out-of-focus backgrounds. Because larger sensors require a different selection of lenses for equivalent focal lengths compared with standard 2/3-inch video cameras, a shallower depth of field is easier to achieve and thus makes these cameras the preferred creative tool. Even if you work with a camera today that doesn’t provide a 4K output, you are still gaining the benefits of this engineering. If your target format is HD, you will get similar results – as it relates to these optical characteristics – regardless of whether you use a RED, an ARRI ALEXA or an HDSLR.
Quite a few large-sensor cameras have entered the market in the past few years. Typically these use a so-called Super 35MM-sized sensor. This means it’s of a dimension comparable to a frame of 3-perf 35MM motion picture film. Some examples are the 
This year was the first time that the industry at large has started to take 4K seriously, with new 4K cameras and post solutions. Sony introduced the F65, which incorporates a 20-megapixel 8K sensor. Like other CMOS sensors, the F65 uses a Bayer light filtering pattern, but unlike the other cameras, Sony has deployed more green photosites – one for each pixel in the 4K image. Today, this 8K sensor can yield 4K, 2K and HD images. The F65 will be Sony’s successor to the F35 and become a sought-after tool for TV series and feature film work, challenging RED and ARRI.
The Canon EOS C300 and EOS C300 PL use an 8.3MP CMOS Super 35MM-sized sensor (3840 x 2160 pixels). For now, these only record at 1920 x 1080 (or 1280 x 720 overcranked) using the Canon XF codec. So, while the sensor is a 4K sensor, the resulting images are standard HD. The difference between this and the way Canon’s HDSLRs record is a more advanced downsampling technology, which delivers the full pixel information from the sensor to the recorded frame without line-skipping and excessive aliasing.
RED launched SCARLET-X to a fan base that has been chomping at the bit for years waiting for some version of this product. It’s far from the original concept of SCARLET as a high-end “soccer mom” camera (fixed lens, 2/3” sensor, 3K resolution with a $3,000 price tag). In fact, SCARLET-X is, for all intents and purposes, an “EPIC Lite”. It has a higher price than the original SCARLET concept, but also vastly superior specs and capabilities. Unlike the Canon release, it delivers 4K recorded motion images (plus 5K stills) and features some of the developing EPIC features, like HDRx (high dynamic range imagery).
Software is easy, but what about hardware? Both AJA and Blackmagic Design have announced 4K solutions using the
