Frame offset, jumps and skips - Dmitry - 24.03.2022
Hello. Can you tell me if there is any way to solve the problem of the jumping frame? The frame shifts periodically up and down literally for 1-1.5 seconds. I tried to use stabilization, but it didn't solve the problem. There is also a feeling that frames are missing somewhere in the film, this is solvable, find individual frames and finish them, if so, with what filter? Thanks!

That sounds strange. Do you have a small file which allows to look at the problem.
If it's captured interlaced and during capturing from time to time one field is lost strange things could happen and unless there's a fixed pattern you probably can't fit it automatically. So I doubt there is a filter to fix that, but depending on the problem one could write a script to fix it.

Here is the link. There are a few moments throughout the piece.

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.
