[HELP] Frame offset, jumps and skips

[Dmitry]

Okay, totally different situation than what I expected.
Thats not missing frames and there are no skipped or lost frames.
That looks like someone captured content and inproperly stabilized it.
Also whoever did it did not do a good job in cleaning the source.
Looks like something like spotless or similar was used way to aggressive. (the lady is loosing here hand quite a few times)

Only chance I see it to manually write a script where you:
1. add different letterboxing values to level the content
2. use one crop at the end
-> lot of work

I used spotless for cleaning, as I didn't find a better option. I plan to replace the broken frames with cleaned ones from the source processed without this filter. There were initial problems with stabilization, the filter helped partially, for minor frame shifts, it could not fix such jumps as in the example.
