I was given the task of editing a video made with a Sony ILME-FX3 camera. The camera works with AVC200_3840_2160_H422P@L52 encoding according to the video xml file.
In ShotCut, according to the file property sheet, the format is yuv422p10le. I tried to convert the videos in ShotCut, but all my attempts failed.
My question: is it possible to edit such a video in the ShotCut program?
Shotcut version 24.06.26 AppImage
MX Linux Xfce, Kernel 5.14.0-4mx-amd64
Was the video shot in a log profile like S-Log2?
I think it’s more of an S-Log3 profile. From xml file:
<Item name="CaptureGammaEquation" value="s-log3-cine"/>*
<Item name="CaptureColorPrimaries" value="s-gamut3-cine"/>*
<Item name="CodingEquations" value="rec709"/>*
</Group>*
In that case, the video does not require conversion in the codec sense. It needs color grading to get out of log space. This can be done with a LUT to get a fast start point, or you can bare-knuckle it directly with color tools.
See this post for info on using S-Log3 in Shotcut along with links to official Sony LUTs for getting S-Log3 into Rec.709:
Thank you very much! This seems to be the solution.
