x264 single pass generating corrupt AVI files

[timmus]

Is there any conceivable reason why rendering a video with ffdshow (3326) x264 in "single pass" mode generates a corrupt AVI with sync problems and "double pass" doesn't? I am doing the rendering in VirtualDub 1.9.10.

The sync problem looks like this: in playback, the video remains black for a fraction of a section but the audio starts right away and from there the video lags by 1 second. When I load the output video in VirtualDub I can see that the first 40 frames (29.97 fps) are stuck in some kind of "freeze-frame".

Workarounds I have tried:
* Just use VirtualDubMod! I can't. The source video is Type 1 AVI from DV, which VirtualDubMod doesn't recognize.
* Just use double pass! I can't. I'd like to, and yes it solves the sync issue, but VirtualDub usually crashes a couple of minutes into any double-pass encode with an inexplicable error.

I saw something that might have something to do with it here http://doom10.org/index.php?action=profile;u=92;sa=showPosts but I'm not sure if this has anything to do with the codecs I am using -- I know I did configure all my drivers a few months ago to support BD Rebuilder so I don't know if I have an incompatibility or not.

Because of all this I've had to drop h264/x264 for my file exports and use xvid, which doesn't cause any problems.

You're using the wrong version , try x264 vfw

http://sourceforge.net/projects/x264vfw/

or

AVI container isn't recommended , it can cause problems with playback (decoder lag and green frames, when using b-frames)

Thanks, that seemed to fix it.

Pointed noted about AVIs... I do want to avoid MKV, so I guess I will have to figure out how to convert Type 1 AVI-DV to MP4... from what I can tell, it looks like a tall order.

you can use type1 to type2 converter (not necessary)

or you can remux it from avi into mp4 with yamb

or the newer versions of x264 vfw can output .mp4 directly if you use the command line box

or vdub has external encoder feature (can use other encoders)

or use another x264 cli gui e.g. xvid4psp, ripbot264, megui, handbrake etc...
