Hi > I'm trying to burn a Digital TV captured file to Disc But the lip sink starts out good but after about 10 mins it's out of sink.
I'm capturing with WinFast DTV1000 T PCI card. Then I'm using UVS 9 to edit & burn with.
Captured File is :-
File Format:- MPEG-2
File Size:- 1.549,648 KB
Duration:- 2219.480 Seconds
Video Type:- MPEG-2, Upper Field First
Total Frames:- 55,487 Frames
Attributes:- 24 Bits, 720 x 576, 16:9
Frame Rate:- 25,000 Frames / Sec
Data Rate:- Variable bit rate (Max. 15000 kbps)
Audio type:- MPEG Audio Layer 2 Files
Total Samples:- 106,535,040 Samples
Attributes:- 48000 Hz, 16 Bit, Sterio
Layer: 2
Bit rate:- 256 kbps

Ok >> with these settings what would you recommend i use in UVS 9 to burn to DVD ?

Regards Paul

Have a look at this post.
Also use SEARCH and place lip sync in the text box and click on "search all terms" for other posts on this subject.

Try turning off the SmartRender function when you render your file. This has been known to work.

If you are burning a standard definition DVD, then the video bitrate you are using (15000 kbps) is way above the permissible limit which from memory is 9800 (and which, I think, includes the audio bitrate). You should, after editing, produce a DVD compliant mpeg-2 using a lower bitrate which is consonant with the length of the project. Then use that new mpeg-2 in the burning module, not the existing project.

There are bitrates and there are bitrates.

I capture MPEG2 TV and many of the clips are interpreted as variable bitrate max 12000 to 15000kbps by uleadVS but I manage to "convert "them to DVD compliant mpeg without encoding. I manage to do this with software called Videoredo. If you run the mpg in Media Player Classic (freeware) with file info on the screen you can see what the average/current bitrates are. If this is always below 9500kbps there is a good chance you can edit this (?chop out the ads and rejoin) without encoding.

The fact that your video is 720x576 suggests to me that it would be unlikely that your true bitrate > 10Mbps

I don't understand all this but I run the mpeg thru the Videoredo quickstream fix and limit the bitrate to 10Mbps by adjusting options. This also remuxes the video and audio and fixes and sync problems at the same time. It happens all too fast for the whole file to be re encoded. I am not sure if it changes some header on the file or ? re encodes segments > 10Mbps.

This way I can quickly obtain DVD compliant mpeg2 for authoring from my TV card. This method has really speed up my workflow, avoiding hours of re encoding (unnecessarily).

Thanks for that tip, Ocular. In fact, I have Video ReDo for other purposes, but had never thought of processing my high bitrate digital TV captures through it. Instead, I use the method I described above, as the end product -- after just one re-encode, is still very good quality. I certainly cannot see any degradation with the naked eye... But I will give your idea a shot!
