[HELP] Audio is ahead of video for half a second

[Selur]

What I established is that my output file plays fine on another computer.

Okay, so the file itself it fine, it might just be a decoder issue.
What player do you use? (if you use VLC try updating to the latest version, vlc 4 nightly build)

However, other MP4 output files that I compressed using an older version of Hybrid play fine on my regular PC as well, and if I compress the AVI with an old version of Hybrid (version 2021.07.18.1) now, it also plays fine. In other words, there has been some change in Hybrid since then that causes output that has this playback issue on my regular PC. And now that you mention it, my system is probably overclocked (which I think I did way back in 2016, so I'm not entirely sure, but almost sure).

Basically all tools Hybrid uses have been updated since 2021.07.18.1, so it's hard to tell what changed.

Both your encodes play back fine. I will check for the duplicate frame tomorrow, as I just dispatched a bunch of jobs in Hybrid.

Please also check whether it works if you use another aac encoder.

And "freezeframe" was a misnomer; the video freezes for approximately half a second (or 42 frames maybe?) at the start is what I meant.
I think I will stick to version 2021.07.18.1 for the time being; that one works Smile

half a second = 500ms = 12.5 frames (1 frame @ 25fps = 1000/24 = 40ms)

I suspect it is either an aac audio or mp4 container issue.
You can also try whether it works with the current version if you enable 'Config->Containers->Mp4 Settings->FFmpeg instead of MP4Box' and thus tell Hybrid to use ffmpeg instead of MP4Box for muxing.

Ps.: going to bed now, but I'm curious to know what's causing the issue.
