WMV video and audio slightly out of sync on conversion to AVI

[Calidore]

I'm trying to convert some WMV files to AVI. Problem is, the audio stream shows as a couple seconds shorter than the video. In its native WMV file, everything obviously plays fine, but when converted, the audio sync gradually drifts off because of the timing disparity.

I think what I need is a free audio tool that will stretch the converted sound file to the correct length, but I haven't found one (Audacity only does percentages, and that's not fine enough). Can anyone help? Thanks!

Have you tried convert to dv-avi with windows movie maker?

Unfortunately, that requires XP and I'm running Windows 2000. Appreciate it, though.

Thanks for the response. I'm sorry it took so long to reply; busy week.

I just tried giving Stoik a 90-second WMV as a test, and half an hour later it had converted a whopping three seconds of it. I'm not impatient by nature, but I'd like to get these things converted before the Bush administration brings about the end of civilization as we know it.

SP4: Yup.

Thanks again. I'll keep trying.

Best,

I have had the same problem quite frequently. However, using Mediacoder as convertor seemed to help in most of the files.

If I remember correctly, the problem is caused as a result of variable-bitrate video in WMVs. As Abrus mentioned, you might have some luck using an ffmpeg or mencoder-based solution. If you'd like a GUI, there's WinFF, SUPER, Mediacoder, etc.

I keep seeing claims that people have managed to get Windows Movie Maker running on Win2K (and WinME, at that). But I haven't really seen a guaranteed solution, yet.

I have tried SUPER and it did not work, don't know why. And in Mediacoder, mencoder works better than ffmpeg. If standard conversion with Mediacoder doesn't work, you can try converting the sound track first without the video to CBR mp3 and then convert the video without sound and then unite them. This causes several conversions and reduces quality, though.

I'll try Mediacoder, thanks. I have tried converting the video and sound separately, but that didn't help; they still show as having slightly different timings.

The video and sound can be recombined without recompression, though, so it's still only one conversion.

My thanks to you and Ai for the suggestions. I'll let you know what happens.

Best,
