Colour managing your workflow

fylm.ai colour manages your workflow by default using the ACES (Academy Color Encoding System) colour management system. Specifically, fylm.ai uses ACEScct, a sub colour space of ACES2065-1 linear colour space, specifically suited for colour grading purposes. For introduction to ACES colour management system and the advantages of implementing ACES in your workflow, see this document.

After loading an asset in the app, the first step you should perform is select the appropriate IDT (Input Device Transform) and ODT (Output Device Transform) for the type of asset you are working with so that fylm.ai app knows how to properly colour manage your workflow and so that your colour grades from fylm.ai will transition seamlessly into other colour grading software, such as DaVinci Resolve, Premiere Pro or Final Cut Pro.

Here we have an image shot using a RED camera in IPP2.

As this image was shot using the IPP2 settings, the appropriate IDT for this image would be ‘RED REDWideGamutRGB Log3G10’.

After applying the correct IDT, an sRGB ODT is automatically selected and the image appears correctly on our screen.

Selected ODT should match the calibration point of your monitor. Usually this would be Rec709 or sRGB. If you are using a differently calibrated and capable monitor, please select the appropriate ODT.

All of your colour grading decisions in fylm.ai take place between the IDT and ODT transforms, namely in ACEScct colour space, so you are not limiting yourself to one particular IDT or ODT. More importantly, if you need to create multiple exports of your work for multiple devices which use different colour spaces, all that you should do is select the appropriate ODT for the type of device for which you are creating the LUT and all of your colour decisions will transfer seamlessly as the fylm.ai app will automatically make the necessary transforms to make sure image is displayed properly on these different devices. This process is called repurposing the colour grade.

Repurposing allows you to easily tailor the grade you have created for a variety of cameras you might be using. Simply change the IDT transform to the appropriate transform for your camera and your colour grade will transfer seamlessly.

Please see this document on LUT export options to learn how to export a LUT from your colour grade and which options to use depending on your typical workflow.

Let’s see how we can colour manage a different image. Here we have an image shot using a RED camera, however this time using a legacy colour encoding using DragonColor2 colour space and REDLogFilm log encoding.

The appropriate IDT in this case would be ‘RED DragonColor2 REDLogFilm’. After using the correct IDT image is displayed correctly on our monitor.

The process is the same for other cameras as well. Here we have an image captured on Arri Alexa in Log-C.

The appropriate IDT to use in this case is ‘Arri Alexa Log-C EI800’. After applying the IDT image is displayed correctly.

Please note that all colour grading tools in fylm.ai are tailored to work with ACEScct colour science. While it’s technically possible to work in a non-colour-managed workflow in fylm.ai by selecting ‘No Input’ and ‘No Output’ transforms we strongly recommend using a colour managed approach.
