VOB to MKV Syncing Issue - PizzaTime - 16.01.2024
Hello,
I am running into an issue where my the audio and video are constantly out of sync when I encode from a .VOB to a .MKV within Hybrid. Sometimes the video plays too fast. Other times the audio outpaces the video. In this example, the video is faster than the audio. I'm not exactly sure what I am doing wrong, to be honest. I am also using dev version 2023.11.05. Please see the attached debug file.
Edit: I tried 2 more attempts with different variables. The first was to change to input FR and check "Always extract timecodes from input; uncheck 'only some'". The following attempt I changed audio to Auto Add All. Debug file includes all three attempted outputs.

Quote: "Always extract timecodes from input; uncheck 'only some'".vobs should be from DVDs which are not vfr, but cfr, so that option only can cause problems.
Quote: I am also using dev version 2023.11.05.Update to latest version (and post another debug output), otherwise looking at the debug output makes no sense for me.

How do I get the latest dev version? I originally got it to get the Torch Addon. Is that in the public version now?
RE: VOB to MKV Syncing Issue - Selur - 16.01.2024
Support for the addons is independent of the version for quite a while. (download for the addons is linked on the download page)
Dev version is recommended to get the latest fixes, but is not necessary.
=> send you a link to the latest dev

Oh nice! Sounds good! I'll report back with results.
RE: VOB to MKV Syncing Issue - PizzaTime - 17.01.2024
Okay. Same results. The closest I got was with the third/final attempt. Speed seemed to look more normal after I changed the input fps to 23.976 instead of 29.97. And the sound just seemed to be a few seconds ahead. At least that's what is appeared to be. I have attached the log.
RE: VOB to MKV Syncing Issue - Selur - 17.01.2024
Input should be detected as 29.97fps soft telecined, which either gets handled by DGDecNV or by applying normal IVTC, but should output 23.976 fps.
According to the analysis the audio should be delayed by 280ms.
Strange thing is, that the vob gets reported as 3.4GB, which is not normal. vobs should not be larger than 1GB on DVDs.
Checking the first log, MPlayer does remort some issues extracing the audio.
a. try whether enabling "Filtering->Vapoursynth->Misc->Source->Use DGDecNV when available" helps.
b. try whether enabling "Filtering->Vapoursynth->Misc->Script->Always use Vapoursynth" helps.
c. try whether remuxing the source file with mkvtoolnix to mkv before processing the file with Hybrid helps.

Option A did the trick! Thank you, Selur!
