I need help:question of displacement video/audio

Pavel wrote on 1/5/2005, 1:01 AM
At viewing written down DVD the significant displacement of flows audio is observed and the video rather each other (audio PCM is late concerning a video ~ 2 minutes in 2 hr. movie). It occurs only at coding in DVD from MPEG-2 to the sanction 640x480 - NTSC in 704x480-NTSC.The displacement also is observed at coding from 640x480 in 352x240 (NTSC). At coding from a file with the sanction 320x240 in 352x240 audio all is not displaced - perfectly.
Processor 2.6 HT, 1024 Mb DDR 400. Why that? I need help. Beforehand I thank.

Is your source video MPEG-2 that was captured by an analog device? A/V sync problems can often be traced to MPEG capture files that appear to be ok, but have defective timestamps and dropped frames that lead to progressive loss-of-sync when re-encoded and burned to DVD.

I grasp from the videorecorder with the help of a videocard ASUS (128 Mb, TV-in). The received film MPEG-2 at viewing it on PC - ideal, and sound and picture. But at record it on DVD and coding it in DVD - the strong displacement between a sound and video is observed. It occurs only at coding with MPEG-2 to the sanction 640x480 (NTSC). If I make DVD of film MPEG-2 with the sanction 352x240, all turns out well both sound and video on DVD. I use Sony Architect 2.0. :-(((

Yours is a very interesting case, given that you can produce an in-sync DVD at one resolution, but not the other.

Are you encoding in Vegas or taking your MPEG directly into DVD Architect? Also, does your ASUS TV card allow you to capture to AVI or MJPEG? Either of these formats would probably be preferable to MPEG-2, especially if the MPEG-2 is encoded in "real time" as you capture.

I am very grateful to you for responses. I am rather puzzled with this situation. Yes, I can grab by the videocard AVI, simply did not do it, as the turning out file has much more large sizes than MPEG-2. I can also
to grab in MPEG-1. Capture of a video I do with the help of the special program delivered together with a videocard: ASUS Digital VCR. I not use Vegas, because I am not familiar with her. Videocoding began to be engaged absolutely recently. I shall try to write down a video with the help Canopus ProCoder 2. There can be this bad effect will disappear. And why it only at me, really anybody with it did not collide? I am grateful for responses. If there will be still information on this problem, write, I necessarily shall see.

Although it's possible to capture valid video with a number of different devices and programs, if I'm going to be editing with Vegas and burning a DVD with DVD Architect 2, I capture with Vegas, which only captures in AVI. The Vegas capture utility is quite simple to learn, if you spend a little time with it.

Yes, the file sizes are much larger, but the format is ideal for editing and presents fewer potential problems farther down the line.

I can't comment on the Canopus ProCoder because I have no experience with it.

Good luck -- I hope you the resolution to your problem is quickly discovered.
