[HELP] Trying to remove VHS dropout (comet tails)

[Selur]

I just tried running the original ProRes 422HQ file through AVIsynth to re-try the DeSpot

not what I suggested,..

now I get a preview error - ConvertToYV12 - only 8 bit sources allowed.

Do I need to convert to standard ProRes 422 for this to work?

Strange, according to the source code Hybrid should be aware that Avisynths DeSpot requires YV12@8bit.
Also tried it and it works fine here:

LWLibavVideoSource("G:\TestClips&Co\files\ProRes\Test Patterns Resolve 422 HQ 10-bit.mov",cache=false,dr=true,format="YUV422P10", prefer_hw=0,repeat=true)
# current resolution: 720x576
# despotting using DeSpot
# Converting from 10 to 8bit for DeSpot
ConvertBits(8)
ConvertToYV12(interlaced=false)
DeSpot(median=false,interlaced=false)

Hybrid automatically converted to 8bit and YV12.
