Here is the video file. It is an old VHS rip of a Canadian TV show from the 1960s. https://drive.google.com/file/d/1vW6FUQP...sp=sharing
In its default state, there's no video/audio sync to speak of.
Hybrid reports it as having a frame count of 81070 and at a frame rate of 59.750. ffmpeg reports somewhere around 29.88 as a frame rate but nothing solid.
Topaz Video AI reports it as having a frame rate of 29.875 and a frame count of 40534, which is obviously false (it should be 40535 hypothetically?), but Topaz famously doesn't display proper frame counts unless the file is set to constant frame rate, which this old .avi is not.
With the "Scale Speed" and "Scale Output to Duration" options on Hybrid, it outputs as a proper 29.97 FPS file with a constant frame rate and good audio and video sync. Except Hybrid and ffmpeg reports it as having 40561 frames, while my media player and Topaz Video AI report 40660.
If I don't select any of these options and just have Hybrid encode it to x264 or something, the file "says" it has a run time of 22:37, but plays as double speed and cuts out halfway through.
So I tried breaking the initial video (the one linked earlier, not one of the ones from Hybrid) down to just images---yes, all 81,070 frames of it. That was 65GB in uncompressed .bmps. Every other frame is a duplicate. Every. Other. Frame.
I'm at a loss what to do with this file beyond just classifying it as "too damaged to function".
The frame rate is most definitely somewhere around 29.97 (with an insane amount of duplicate frames) even though I can't figure out what to do.
