[CinCVS] Render is choppy

[Matt Pfingsten]

As I stated in earlier posts I can play back DV quicktimes fine in MPlayer, but they are always choppy in Cinelerra. Even when I advanced one frame at a time in Cinelerra, the viewer or compositor only updates the image every 3-4 frames, no matter how long I wait after advancing to the next frame.

Well, perhaps this helps me understand more of why Cinelerra is performing so badly on my machine, but I just tried to render something. It's a 30 second sequence of several clips joined together with dissolves. When I watch the rendered video (exporting to Quicktime for Linux, DV compression, no sound as it is not needed for this clip) in Mplayer, the dissolves play out at full frame rate (29.97) but not the underlying video, which is as choppy as it is in Cinelerra.

So it appears that in playback or in rendering Cinelerra is simply skipping certain frames and not reading them or displaying them at all. Has this happened to anyone else? What could be causing this? I've used Cinelerra before and this never happened. Any ideas?
