I'm having a problem with Premiere 6.5 when I'm editing a widescreen video shot in frame (progressive) mode. It slows down after about a half-an-hour and I can no longer preview frame by frame - the 'frame' remains static for five-ten-fifteen frames and then jumps to the corresponding frame. Almost as if there were no frames between frame 0 and the one it jumps to. I hope that's clear. It works fine during normal play mode. This happens with both the timeline and the clip preview. Restarting Premiere will give me another half-hour before it stops working again. I'm using Win XP Pro on P3-933 with 1gig of RAM and 40G of scratch disk space. The clip I was editing when this occured is only 3mins long.
I've edited widescreen before without any problems but this is my first progressive mode + widescreen flick. I'm wondering if I've missed a setting. Any suggestions?
