I have been having problems with exporting video using Adobe Premiere 6.0. When I export my timeline to mpeg, using the "Save as web" option it works find and it outputs the mpeg, but for some reason when its done and I go to watch it, the first 30 to 50 secs of the movie is fine, but then after that the frames start slowing down the audio becomes out of snyc with the video, and the video becaomes choppy and this gets much more bad as the video moves on. I'm on a P3 1 GHZ, 512 SDRAM, on a 60 gig 7200 HD. When I export to DivX or anything else but mpeg PAL, or NTSC it works fine but, mpeg is messed up for some reason. I love be greatfull for some feedback on this problem.
