[FFmpeg-user] Video filtering for chroma dot crawl and rainbow effect

[Christian Johannesen]

Looked through all the documentation for FFMPEG and I can't seem to find
any video filters that deal with chroma dot crawl & rainbow artifacts in
files captured from analog tape formats. I have a feeling that I am going
to need to immerse myself in AVISynth, but if anyone has any leads I would
appreciate any info.

Thanks,
Chris
