[solved] Converting to DVD/MPEG2 - A/V Sync

I'm sorry if this post doesn't belong here I have a AVI with this info : Video : FrameCount : 151457 FrameRate : 25 FPS Duration : 1:40:58,280 Audio : Type : MP3 / CBR SampleRate: 44100 Duration : 1:40:56,515 AVIMux and MediaInfo gives me only 3ms delay, nothing big or problematic, it is easily fixed with DelayCut as I do with any movie with delay When I convert to a MPEG2 Stream using HCEnc, or other encoder such as CCE, I get gradual loss of v/a sync. Everything is normal at the beginning of the video file, but audio is gradually shifting during playback. At the end there is almost 3 seconds delay....and this is a CBR MP3...not a VBR If I Uncompress Audio to PCM in VDub, I get the same a/v issue But I can easily fix that by changing Video FrameRate to 25.007 FPS instead of the normal 25 FPS, and I can get a a/v fixed AVI.. But when I try to convert to DVD, here is where I'm in trouble I used AssumeFPS(25.007) in my Video Script, and tried to encode with HCEnc.....but there was no change in video playtime/duration I didn't changed Audio SampleRate, I kept 44100, but tried with SSRC(48000) without success How can I force Video framerate in order to match audio play time ? is there any solution ? thanks

1) Load the .AVI into GSpot and post a screen capture back here 2) What is the Title and Region number of your original DVD? 3) What software and procedures did you use to rip your original DVD? 4) What software and procedures did you use to convert your oroiginal DVD to .AVI? 5) Does the original DVD exhibit the same behavior? 6) Does the .AVI exhibit the same behavior? 7) Why don't you just make a (compressed, if necessary) backup of your original DVD?

Where did you acquire this AVI file from? If it was made from a DVD why don't you just make another copy of the DVD?

To state the obvious... 1. The video and audio durations are different. If the end is simply missing from the audio, then any program that stretches the audio duration to match that of the video will cause a sync problem. 2. The audio is 44.1kHz. DVD requires 48kHz. Check the resampling is working properly. 3. You must use 25fps for "PAL" DVD. It's pointless trying any other frame rate - it's not supported. Yes you can us DGpulldown to add duplicate frames, but in this case it seems obvious to fix the audio, not change the video. 4. Read the forum rules. Cheers, David.

======== 2. The audio is 44.1kHz. DVD requires 48kHz. Check the resampling is working properly. ======== I checked that already, no problem with it ===== 3. You must use 25fps for "PAL" DVD.

I know that 25 is the standard ===== 4. Read the forum rules. ===== Why are you saying that ? I'm always careful with forum rules

Why read the forum rules? Because what you're dealing with sounds like an illegally obtained video. You still haven't answered my question of where you got the material to begin with. If this was made from a PAL DVD, why are you transcoding it back to a DVD again? If you own the DVD just make a copy of it, if you don't (which it sounds like) you're violating rule 6.

For just a 0.028% speed change stop stuffing around with TimeStretch and just reclock the audio, you have to resample it to 48000 anyway for DVD. Code:
