Please stop being rude. Your input is not "uncompressed raw video", it is an
AVI file, you did not tell how it was generated and AVI is one of the worst
formats there is. Expect all sorts of problems.

In the future, maybe you will remember you should never work with frame
numbers but always with timestamps.
