Hi Guys,

I am currently encoding exclusively from Divx sources. I repeatedly see audio slippages and bad frames in resulting KVCD's with these sources. I'm a little perplexed as to their origins, but oh well...

I load these source .avis into Vdub and scan the video for bad frames, and make the determination to encode or not from the resulting numbers it gives me. Should I be concerned only with bad frames, or are the 'good but unreadable' frames also a problem??

To date I've only used Vdub to snatch audio, and check for bad frames. It seems to be perfectly capable of re-assembling the .avi without the bad frames, but I honestly haven't looked into it yet. Any pointers??

Alittle app I have found good for scanning for bad frames is here

You can also use vitual dub to del bad frames when you find them and save the end result as a new avi but this app does all that anyways.

Could corrupt frames in an .avi source cause audio to slip? Or is that something else I have to worry about?

Yes, I'm pretty sure, that those bad frames cause the slipping.

But you can take this tool called divx repair to fix it.

Yes,

The beauty of Divx repair is that it deals with audio+video so if it removes any bad video frames it removes the corresponding audio to keep all in sync.

I have had problems with this, the audio works fine in the original, but when I encode it to a kvcd the audio goes out of sync after a few bad frames

I have had very little trouble with any damaged DivX. As most DivX/XviDs I've had are pretty much perfect...you should try to get them from a reliable source. *COUGH*sharereactor.com*COUGH*...

I have had some trouble though, so thanks for the tip about DivXRepair.
