Beh Jing Qiang April 16, 2020 Share April 16, 2020 Hi everyone I have a question regarding to how to convert a linear space file correctly to my camera's footage, in my case its RedWideGamut, Log3g10. Here's my scenario: We shot a project on the Red Gemini, and we have to do some greenscreen key. Our VFX artist uses the standalone Fusion, and I exported EXR image sequences for him. As usual, I leave my project Color Management as default, but my CameraRaw is set to the IPP2 Color Science, RedWideGamut as my color space & Log3G10 for my Gamma Curve. Go ahead and export all these shots to EXR float. I just checked the VFXIO 3D LUT folder and realise there is no Linear to RedWideGamut,Log3G10 option. I tried using the Color Space Transform OFX, using these settings: Input Color Space, Use Timeline ; Input Gamma, Linear. Output Color Space, RedWideGamut; Output Gamma, Log3G10. The footage came out even flatter than the original footage. Is there any other way to convert the Linear footage into a RedWideGamut, Log3G10 correctly? Thanks!

Jussi Rovanperä April 16, 2020 Share April 16, 2020 The vfx might have used the wrong log-to-lin transform. Link to comment Share on other sites More sharing options...

So when I take that footage back to Resolve, how should I perform a Linear to RedWideGammut transform? Link to comment Share on other sites More sharing options...
Jussi Rovanperä April 16, 2020 Share April 16, 2020 Try Color space transform with these settings: input gamma: linear input color space: timeline output gamma: try redlogfilm or logc (those would be the most common log formats, redlogfilm is same as cineon ), or just ask what log to lin the VFX have used, and use that. output color space: timeline Link to comment Share on other sites More sharing options...

Appreciate it! Edited April 17, 2020 by Beh Jing Qiang Link to comment Share on other sites More sharing options...
