Why is my audio desyncing in VirtualDub? - digitalFAQ Forum
http://www.digitalfaq.com/forum/video-capture/12178-audio-desyncing-virtualdub.html
After about halfway through the video, the audio will start to desync (maybe it is doing it earlier and it is so minuscule I don't notice) by the end, the audio will last nearly 5 seconds after the video itself has ended.

To clarify: Video -> Direct Stream Copy in VirtualDub copies the input video to the output file without even decompressing it. No filtering is performed by VirtualDub.

It can properly pipe to x264 and other video/audio encoders and also automatically mux using e.g. mkvmerge.

Audio pitch issues with Virtualdub - Speed Demos Archive
https://forum.speeddemosarchive.com/post/audio_pitch_issues_with_virtualdub.html
There's no desync between video and audio, and as far as I can tell, neither the video nor the audio is speeding up or slowing down. The game audio just shifts up or down in pitch at seemingly random intervals.
