Delay relative to video : 67ms

Jul 27, 2013 at 8:31 AM
This has become an issue. I encode cartoon videos that average somewhere around 7 to 10 min. I use Vidcoder exclusively because I can queue up a batch at night, and they will be done the next afternoon. I like HandBrake because of its ease and quality of encode. The issue is, every video is around 67ms out of sync. That means another process thru AVIDemux to sync up the tracks. That creates a problem with the x264 encode by HandBrake.

I have tried different seyttings for the audio and have tried pass through. All of the videos I do are from whatever the original is in to MPEG4 x264 AAC. Here are my settings for Black and White cartoons


For Color, they are relatively the same and may have a minor change, depending on original quality.


I can send the log, however it is large and I don't know where to upload it to so you can see it.

Here is the MediaInfo on the completed video.

Sync problems would most likely be with the underlying HandBrake engine. See if you can reproduce it with HandBrake and if so report the issue to them. You can put the encode log on pastebin.

Thanx. I've been chasing this for some time and you idea fits with mine. After doing some more research, I ran into different and unrelated posts in various places where the poster was having some related issues. It appears that there has been some kind of sync issues lurking for a while. These vary from VFR/CFR issues to Quick sync. This may have been taking different forms depending on Frame rate, sample rate, actual codex used for AAC, and whether or not the actual stream is supported when using pass through. Seems some may not be and those revert to another form of AAC codex.

Problem I have is not knowing a damn thing about what I'm trying to do. So I will just keep stumbling around in the dark until I accidentally trip over what I need. I'm so confused that I can't even sort out the problem with out becoming totally frustratred.

More will follow when I have a few beers. That should put me in a better frame of mind. Maybe a toke?? We'll see.

Thanx so much for the ideas.

If possible, try adding "/ async 1" at the end of your encoding settings. I think Handbrake uses ffmpeg, so worth a try. It works in WinFF when encoding XviD.

I gave this a try with no change in results. Maybe if I take a nap, this will all go away??

Something interesting. I've been working with blinders on. Trouble is, that's like tunnel vision. I changed containers from MPEG4 to MKV. The problem went away. Now isn't that just special?? Maybe it's the way x264 fits into the container. It likes the Russians better.

Incidentally, it has to be the x264 codex, NOT HandBrake.
