With the proliferation of digital video cameras, everyone has been trying to make their video footage look more like film. Assuming your camera shoots at the right frame rate and offers film-like motion blur and highlight handling, the rest gets down to grain and colorimetry. That’s where software tools and filters come in.
Nineteen stock selections are available in FilmConvert and the After Effects plug-in.
A new film stock emulation application is FilmConvert from New Zealand-based developer Rubber Monkey Software. Best known as one of the early developers of processing and rendering software for the RED ONE camera, Rubber Monkey is expanding that expertise into tools designed for a wider appeal.
FilmConvert is available as a standalone application (lite and pro versions) and as a plug-in for Adobe After Effects/Premiere Pro (Windows or Mac) and Apple Final Cut Pro X. The standalone FilmConvert Pro goes beyond film emulation to include a powerful three-way color corrector and render management. The software works with QuickTime files and native RED .r3d files from a RED ONE or EPIC. It also supports round-trips between FilmConvert and your NLE using XML and EDL files.
Film Stock Emulation
At the time of this writing, only the film emulation module is available in the plug-in versions. (Rubber Monkey plans to add color correction to the filters in the near future.) To create the film stock emulations, the developers analyzed scans from a variety of color and black-and-white motion and still photo stocks made by Kodak, Fuji, Ilford and Polaroid. By shooting color charts with the various stocks, they were able to engineer custom color curves that enabled them to produce digital camera images that closely resemble the appearance of these scans. That color science forms the basis of each film stock preset. The standalone version and the After Effects plug-in include 19 stock selections, while the FCP X filter includes eight.
RED ONE and RED EPIC camera files are natively supported and automatically detected.
FilmConvert Pro and the FilmConvert filters work slightly differently from each other. The standalone version allows you to set the initial color profile of the image as either a default sRGB or as StatusM Log—a flat setting similar to ARRI Log C, BMD Film or REDlogFilm. If your camera file was already encoded with a flat gamma profile, then leave the viewer set to sRGB so you don’t apply a log curve twice. Native .r3d files can be imported and are automatically detected so that the “as shot” metadata may be applied. Native Canon camera files are also separately profiled. Additional digital cameras (including Panasonic DMC-GH2, ARRI Alexa, Canon Cinema EOS C300 and the Blackmagic Cinema Camera) are currently being profiled by Rubber Monkey engineers. The After Effects plug-in includes a pull-down menu to select the camera profile as a starting point for any adjustments, but log-to-video conversion must be done with other filters. There are no camera profiles in the FCP X version of the filter yet.
The film emulation module itself includes the same controls for all versions. These break down to exposure and color temperature sliders, the film stock selector and a percentage slider for how much of the emulation colorimetry to apply. Grain is added by adjusting a percentage slider for the amount of grain and selecting the film type that determines grain size. 35mm Full Frame would be the finest level of grain, while 8mm would be the coarsest. You can zoom the viewer for a 1:1 pixel view, which will give you a better sense of how the grain will actually look on your image.
Color Correction Tools and RED in FilmConvert Pro
Batch processing and round-trips with edit systems via XML and EDL files are available with FilmConvert Pro.
The standalone FilmConvert Pro includes a color correction toolset. The color correction module includes color balance wheels and luma sliders for shadows, midtones and highlights. There’s a saturation slider and a levels pane for black, mid and white points. Between the color corrector and levels, you get much of the same horsepower as the primary grade settings in any high-end color corrector. FilmConvert comes with a series of presets, such as “70s Home Movies” and “Matrix,” and you can create and save your own. Any of these may be applied to clips on your timeline.
You won’t find the typical RED color science and debayer settings seen in REDCINE-X PRO or some of the RED SDK importers. Rubber Monkey explains the approach this way: “For extract settings with .r3d, we choose the best extract settings for our emulation. If the user changes the extract settings, then the starting point will be different and it will throw out the film emulation. If our film emulation is applied at 100 percent, you get an sRGB film emulation, not a variation of a RED color space—so the actual input color space is not quite significant in this case. The .r3d debayer always uses the size that is greater than (or equal to) the size being rendered. So if you are rendering to 1080p, then we will render at 1/2 debayer. Basically we made it so that we are always scaling down, never up, but also going with the fastest debayer that would not sacrifice quality.” FilmConvert Pro also supports the RED ROCKET card for hardware-accelerated rendering of .r3d files.
The FilmConvert After Effects plug-in is also available in Premiere Pro. Both allow film emulation presets to be applied to native RED files within the application.
The FilmConvert filters work like any other plug-in, where the host application controls how the media is sent to the plug-in and then the subsequent renders. The standalone version includes its own render management tools. Render options include QuickTime (H.264, MPEG-4, ProRes or uncompressed) and image sequences (DPX or TIFF). The default export sizes can be up to 2048 x 1152 (or larger custom sizes) with fit width/fit height/stretch controls. This is great for RED projects that are rendered into HD or 2K formats.
There are two workflows to handle renders. The first is to simply import one or more clips into FilmConvert Pro, apply the look you want for each clip and set them up to render as complete, individual clips. The other option is to edit the footage first without effects in an edit system and then export an XML or EDL file for the completed sequence. FilmConvert Pro will import the file and locate the clips. In the case of RED camera files, you can choose to link to .r3d files instead of QuickTime .mov files that may have been used for edit proxies. Each clip is loaded onto FilmConvert’s timeline with markers for each section of a clip that was used in the edited sequence. Unfortunately, you can only apply one setting to the full clip. If it was an outdoor shot and you used a portion that was overcast and then a later section of the same clip where the sun came out, there is no way to split the clip in order to have two different adjustments.
When you render these clips as QuickTime movie files, the complete duration of the file is rendered, but images are rendered only for the sections that show up in the EDL or XML file. The rest of the file appears with a placeholder graphic. Rubber Monkey took this approach to maintain one media file when multiple portions are used in the edit, rather than to render separate, shorter clips for each portion. A single media file keeps the same file name and is easier for applications to relink. New, multiple media files require an additional naming convention—such as appending a numeric suffix to the file name, like .001, .002, .003, etc.—in order to preserve unique file names. The latter method is how Blackmagic DaVinci Resolve, Adobe SpeedGrade and FilmLight Baselight handle such renders. This requires the generation of new EDL, AAF or XML files so that the media can be correctly relinked in the round-trip back to the NLE.
Rubber Monkey promotes its render prowess, and speeds were good on my 8-core 2.26 GHz Mac Pro. I don’t have a RED ROCKET card installed, so a 4K 16:9 RED file (exported as a 1920 x 1080 ProRes file) took about 20 minutes for a clip of 4,933 frames (about 3.5 minutes of footage). By comparison, 1080p QuickTime files rendered at near-real-time speeds—some faster, some slower.
FilmConvert also supports FCP X with a filter, though the number of stock presets is limited. In this example, a Pomfort LUT filter is providing log correction to footage recorded in a Blackmagic camera using the BMD Film profile. Then the FilmConvert filter is applied for the film stock emulation
In most color correction applications, you can specify the length of render “handles,” where the clip gets an additional second or two of media at the head and tail of the exported clip. It appears that FilmConvert adds five frames to the head and six at the tail (24 fps clips), but there’s no place to increase that or to set a custom length.
FilmConvert Pro doesn’t support I/O hardware like AJA or Blackmagic cards, so you are making color correction judgments by viewing the interface on your computer screen. By eye, I would say the display within the FilmConvert interface looked a bit “warmer” and more saturated than an exported file viewed in QuickTime Player X (not surprising), but also as compared with FCP X. It tended to look closest to FCP 7.
If issues such as SDI monitoring and clip control are critical for your workflow, then the After Effects/Premiere Pro plug-in might be a better option than the standalone application, especially once this plug-in gains color correction controls.
I’m sure some of these missing features will be addressed, along with better documentation, as the application matures. Rubber Monkey is also working on an OFX plug-in to cover Sony Creative Software Vegas, Assimilate Scratch and The Foundry Nuke.
Whether a plug-in or the standalone version is right for you depends on your need. Do you just want to augment a few shots, or are you going to build a pipeline around this look? As for the plug-ins, the Adobe version offers more features than the FCP X version, but either makes a nice addition to your toolkit. The film stock looks are spot-on, and if you want something vintage, the Polaroid emulation is really nice. If you want your digital media to come closer to the look of film, FilmConvert is definitely worth the investment.
