Audio not fully sync after feeding through Hybrid
#8
Quote:I downloaded the tool, not exactly sure what to do next?
Extract install the tool, when like I wrote:
Quote:... start mkvtoolnix-gui, drag&drop the input file, start muxing.

Quote:Do I use the unedited capture as the source file or the edited capture as the source file?
The sync input you would otherwise feed to Hybrid.

Quote:What purpose does this make?
The purpose is to understand what is causing your sync issues.

Quote:Video is x264 with Audio set to "passthrough all".

Okay, reading that I'm confused. You write you use Avisynth for resizing, but Vapoursynth for deinterlacing, that does not make sense.
Hybrid can only use one or the other at the same time. According to the debug output, Vapoursynth is used.
Tried to reproduce the issue with a HuffYUV file I got here, but could not.

Looking at the debug output, here's what Hybrid does during the job processing:
  • Starting subjob 2022-04-24@21_00_11_2310_01_audio:
    Here Hybrid extracts the audio using:

    Seeing that you use an input file created by VirtualDub and that FFMS2 is used as a source filter you could try whether enabling "Filtering->Vapoursynth->Misc->Source->Prefer AviSource for .avi input" changes anything.

Hybrid does not detect any errors or warnings from the tools used, so the synch problem you notice either:
  • is created during the audio extraction (during which parts of the audio would need to get lost),
  • the video filtering/encoding (during which parts of the video would need to get lost),
  • using the audio&video multiplexing (during which audio&video do not get properly synched), or
  • the auio&video are not asynch and it's an issue with the playback.
To test which might be the issue you could tell Hybrid to not delete the temp files. (Config->Containers->General Settings->Keep intermediate files)
And then compare:
  • the extracted audio with the audio of the input source (fed to Hybrid) to see whether the unprocessed source audio and the audio that got distracted differ.
  • the reencoded video with the video of the input source (fed to Hybrid) to see whether the frame count is correct.
  • You could try whether remuxing the source to mkv before processing with Hybrid or causing Hybrid to use another source filter does change anything. (this is what the remuxing with mkvtoolnix and the switchting to AviSource which I both mentioned earlier would be for.)
