Video and audio out of sync

I have a new Sony camcorder which stores the video directly on internal harddisk. I import the recorded files from the camcorder via USB onto the computer. The inported video mpg2 files as sound-synchronised in MSMediaplayer and in other players. But when I import this files in MSP 7 then the audio is about 15 frames out of sync with the video.

Until now I split the Video-Audio en shift the audio 15 frames. This will result in a good solution. But this i not the really kind of working.

How can this sync-problem be solved???

Same problem in DVDMF4. I guess it is a Ulead codec problem....

You haven't told us much about the Sony Hard Drive camcorder.
Are the files on the camcorder hard drive recorded in MPEG format or in DV (avi). If they are DV then you need to import the video as DV.

My understanding is the sony cams have 30 gig (or some similar) hard drive. they store everything in MPG2 not AVI. for this reason i won't buy one, because MPG2's compression must be converted to a more friendly (but larger) AVI format to really be effectively edited in MSP. As i understand it, MPG2 is a good final *output* format, not a good format for editing, as the compression is very great.

If you convert the MPG2 to AVI using some conversion program, what happens to the sync with the imported AVI?

The Sony SR190E camcorder has a 40Gb harddisk. The video is stored as MPEG2 format (DVD bitrate and quality). I know that the DV-AVI format is of a higher quality as the MPG2-DVD format, but normally all video's will be finalised on DVD. And therfor the MPG2 format ihas a sufficient quality.
When I need the higher quality then I use my older Sony camcorder
TR7000E which stores video on Digital8 tape in Dv-AVI format.
With this AVI-format the video-audio sync is OK and has no delay when I use MSP7.

Editing MPEG video involves a lot of luck. Some are able to edit it without the sync issues, others (as yourself) are not.

I would disagree with converting it to another format such as avi, or DV, because it will have to be recoded to MPEG2, when you prepare to burn your DVDs. This will degrade the quality.

Sometimes editing smaller amounts will help keep it insync. I've read DVDDoug's posts, recommending to cut larger files into smaller ones. Don't place any transitions at these cuts, just leave them as hard cuts.

Other then that you may need to use a program like Womble Multimedia to edit your MPEG videos. It is designed specifically for MPEG.
