Audio out of sync after TMPGEnc DVD Author

[kcfrogg]

I have a MPEG2 file from PowerVCR II which I caputured with my ASUS TV card. When I watch this file with my DVD software, the video and audio are perfectly in sync.
Using TMPGEnc, I see there are 3 streams in it:
1) Video stream MPEG-2 Video 720X480 29.97fps 4000kbps
2) Audio stream MPEG-1 Audio Layer 48000Hz 224kbps
3) Padding stream (no other info)

When I give it to the authoring tool, the end result is that the authored dvd files have the sound out of sync with the video. It starts out ok, but gradually gets out of sync, up to about 2 seconds in the 17 minute video. This happens with TMPGEnc DVD Author and DVD-Lab. I have tried Muxing and demuxing the sound and video, all with the same results.

I suspect the padding stream has something to do with it, but I can't figure out what to do to make it work.

All I want to do, is take my MPEG streams I capture from TV and put them onto DVD to watch at a later time (from my big-screen tv)... It shouldn't be this hard... :(

Can anyone steer me in the right direction?

Best Regards,

Gregg

Have you tried feeding TDA with demuxed video(m2v or mpv) and audio(mp2 or mpa)?

I fed in both the demuxed audio and video. Same result. I tried re-encoding the audio to 384kbs (from 224), but that didn't have any effect either.

I also selected the "re-encode audio" option in TMPGenc DVD Author, all with the same result.

I tried feeding the files (muxed and de-muxed, both ways) into DVD lab, and the end result was out of sync audio also...

I can't figure out what the deal is... Has anyone ever taken output from PowerVCR II and put it to dvd?

Anyone have any other suggestions?

This could be a workaround: Feeding demuxed video & adudio: You could decode, then stretch and finally re-encode the audio to match the speed of video. To accomplish it you need to find out what the delay is at the end of the clip. (Assuming it's in sync. at the start. If it isn’t, you need to take a general delay into account…) I did something like that with an mpeg2 captured clip (using an ati board).

BeSweet and BeSweetGUI are the tools you could use to do that. In just one step: Depending on the “speed” of the audio if it’s faster than video (sounds ahead of movements) or slower (sounds after movements) you would enter in the “Change Frame Rate” from and to fields under OTA options the difference you notice. For your clip it would be from/to: 1020/1018 or 1020/1022 (=17*60 & 17*60 +/- 2)

Hope that helps, :J

I was really hoping to find a way to record directly to some decent MPEG-2 (dvd) format, so I could just dump the .mpg files directly into something like dvd-lab or TMPGenc DVD Author.

I didn't want to spend a bunch of time re-encoding a tv show, just to watch it once. I just want to be able to watch my recorded program on my big-screen relatively easy....

I'm sure someone has done this before, haven't you? :)

Should this be in the capture forum btw? I didn't know if it was a capture problem or a Authoring problem....

I use powervcr and just put the file into video studio 6 and edit out the commercials and let video studio 6 make the dvd. I found that tmpgenc has sync issues. If you can afford it I find CCE does a great job encoding, its really fast and I never have sync issues.
