Quote:Remuxing the source with ffmpeg in a command line to see warnings&go might help.
How do I do that? Is that on the MKVToolNix software or do I have to type it in cmd?
-
Another note although you say it was an estimate, when I did the the simple remux, I loaded that up in Hybrid and it shown it has lost 182 frames, almost the same amount of frame loss than doing it before. The least amount of frame loss I got is when I tick prefer avisource for .avi input. I don't think it your software not being able to handle it since it also happened when doing a simple edit like changing the RGB filter on VirtualDub itself.
Another troubleshooting I could do is attempt it with a completely different VHS tape since the problems regarding the syncing has all came from one particular tape which I have found to have several jitters and weird artefact, there definitely something off with that tape but I could be wrong.
It seem like I'm not the only one who encounter this tedious problem when capturing VHS.

You can also try whether it makes a difference if:
a. "Config->Internals->Decoding->CFR Output" is enabled
or when
b. "Config->Internals->Automation->On Load->Always extract time codes from input" is enabled (and 'only some' is disabled)
Quote:"PATH TO Hybrid/64bit/ffmpeg.exe" -c copy -vsync 2 -i "PATH to source" "PATH to output file"
Is a command line call, you need to call inside a Windows Command prompt.

Unrecognized option 'copy'.
Error splitting the argument list: Option not found
Edit:
So I tried doing CFR Output enable without ticking the prefer .avi source for .avi input and it still not sync but only lost around 10 frames.
Also tried doing it with "Always extract time codes from input" enabled and 'only some' is disabled and that lost about 182 frames.
Out of the tests I did, ticking CFR Output or Prefer .avi source for .avi input settings seems to mitigate the async and less obvious but it not 100% synced. (For some reason, the Prefer .avi source input setting now has an extra frame, from 38311 to 38112 frames. I know the frame thing is an estimate but still strange since it previously said 38311.)

You missed a '-', should be '-vsnyc 2'.
+ I made a mistage should be '-c copy' instead of just '-copy'

It seems like ffmpeg has some problems with the headers of the AVI.
Additionalls there are three places in the clip where the time stamps are not correct for 25fps.
My guess is the combination of both is what causes the problem. (Hybrid isn't desinged to deal with content where the input has sync issues&co.)
Is the .avi sync if you open it in Virtual Dub? If it is may be converting to another lossless format and using mkv as container in Virtual Dub helps to get a file that can be processed by libav based tools.

Okay, if a basic remux with ffmpeg and mkvtoolnix both create an async output there is something wrong and Hybrid can't fix it.
No clue whats the cause if the original file plays fine.
(Could be an issue with the file or the system, or both ffmpeg and mkvtoolnix having some problem nobody encountered so far.)
-> I'm out of ideas.

You did what you can to help which I'm very thankful for, I think I know how to mitigate the problem though and finger crosses it only happened on that particular VHS tape.
