Scramble video x sync

[joelson]

Hi All!

I have an AVI file, encoded in Xvid. I have converted it in MPEG-2 (using TMPGEnc), and I saw that in the end, the sound and image were out of sync.

Looking the original AVI, I realized that it contains a (short) scrambled part. After that point, occurs the loss of sync.

The question is: how can I convert to MPEG-2, without losing the sync?

Cut the scrambled part out. Scan for bad frames. Hope for the best. Most times you got an aborted clusterfuck on your hands that ain't worth ******* with.

Very succinctly put, and I agree. If you still want to try, check out this guide.

sacajaweeda: THANK YOU for the hint!!! That was the solution!

teegee420: Thank you for the link to the guide!

It finally worked, thanks to your help!

Just a doubt: in the original AVI file, the scramble was already there, but the audio and video were in sync. How the lack of sync showed up only in the generated MPEG file?

The badframes you had would have caused the encoder to struggle past the video that was bad the audio would have carrried on encoding as normal , when the video stared encoding again it would have been delayed so the video was out of step to the audio.

Its always worth scanning for badframes before encoding any downloaded AVI file , If you have bad frames right near the end you could spend 3 hours encoding and have to start again , it's definately worth spending 15 mins to make sure your file is ok first.
