Film emulation LUTs (color look-up tables) are always a popular discussion point and I’ve covered a number of the products on the market. Some of these are plug-in effects that include 3D LUT files as part of the package, like Koji, Color Finale, FilmConvert, etc. Others are toolkits with different types of files that are designed to be mixed and matched, like SpeedLooks, Osiris, ImpluZ, and others. One of this latter group is Rocket Rooster. I’ve mentioned them before, but in this post I’d like to go a bit deeper.
Rocket Rooster offers a range of “look” products that together become a toolkit for any type of film emulation, whether we are talking about motion film (3D LUTs) or still photography (Lightroom and Adobe Camera Raw presets). For video, these include log-to-Rec709 correction, negative stocks, print stocks, combined negative/print LUTs, and various subjective “movie looks”. As with many other film emulation products, they should be viewed as a starting point and not the only process that you would apply to get your final look. The Rocket Rooster packages include LUTs in .cube, .3dl, .icc, and .mga versions to be compatible with just about any editing, grading, or compositing application. The method of importing and adding external LUT files varies with each software. For example, in Final Cut Pro X you’d need Color Grading Central’s LUT Utility. In After Effects, you’d need Red Giant’s LUT Buddy. Premiere Pro CC, Resolve, and Media Composer all enable direct access to an external file.
There are different ways you can work with these LUTs. For example, if you shoot with log profiles, then Rocket Rooster offers both log-to-Rec709 camera patch profiles, as well as LUTs that combine the log conversion with a negative film stock setting into a single file. Since many of these looks work best when you combine a negative and a print stock (as you would in real film production), the next step is to pair the negative stock LUT with a matching print stock LUT. The Rocket Rooster film stock choices include several Kodak and Fuji emulations, along with a series of in-house creative presets designed to be reminiscent of certain popular styles.
Within your application, you have to bookend both LUT filters around a color correction filter, so that the grading adjustments occur between the two LUTs. For example, in FCP X, you would apply LUT Utility and select a log-to-negative LUT. Place a color correction filter next, followed by a second instance of LUT Utility. For the second LUT, pick a print stock LUT that you like. Premiere Pro CC makes this easier with the new Lumetri Color panel. In the basic correction tab, select the log-to-negative LUT and in the creative tab, pick the print stock LUT. In both NLEs, you’d use the color correction tools to hone the desired look. Rocket Rooster also offers a set of integrated files with both negative and print stock emulations in a single LUT file. With these, you’d select the file based on the negative stock you want to use, but the built-in print emulation is standardized on Kodak 2383.
Unlike other developers, these stock emulations tend to be a bit more aggressive in matching the coloration of the stock, but are more subdued in terms of final output contrast and saturation levels. That’s to allow enough margin in the resulting color for further grading. There are variants with different contrast balances for use with higher dynamic range cameras or that are readier for final output. All of this is spelled out in their user guide.
As with most LUT packages, you have to play around to get the right combo for your desired style. A little trial-and-error is part of the fun and experimentation. Of course, this process has to be interactive with your color correction tweaks to get the right look. Below are a series of stills demonstrating some of the results that are possible. Each of these uses one or two of the Rocket Rooster LUTs along with a varying amount of Lumetri Color grading. (Click on any image for the slideshow.)
