Target FPS + RIFE interp produces artefacts in the footage

[codedealer]

Set footage's TargetFPS to lower than the source (e.g. 30 for a 60fps source), enable x2slow interp with RIFE. Produces video glitches, that are absent if interpolating the source footage or if just setting its TargetFPS.

Does this apply to both SDR and HDR sources?

@baenary this needs further investigation. If you have any details on how to test this provide them in this thread or contact me on discord

Following up on this, it supposedly happened due to improper colorspace conversion of HDR footage in the RIFE pipeline, where the frames are encoded into jpeg for interpolation but then are forced into 8-bit representation on decode.

It should be fixed in 1fac964 but I will keep this one open for now.
