On a particular project, I need to re-render everything everytime I re-open project even after I have saved and closed project.
I also experience SERIOUS ERROR crashes or simply PP3 freezes while trying to render whole timeline, I need to render in chunks.
The project file is a single timeline 2:45 minutes long with only the clip on timeline in project; it's CFHD low res clips (not corrupted) and there's quite a lot of CF cross-fades in timeline (it's a trailer) with about 5-6 clip color corrected that need to be rendered.
I am having the same issue. I am also using AspectHD v5.2. The timeline which I am having this issue has many effects and also has some imported Photoshop files. Another aspect of this is that when I try and play the timeline the play-head jumps to the end of the timeline. If I render the clip it plays fine. Except when I exit Premiere and then open it again the renders are lost and I'm back at square #1. I have been struggling with this since November and am not sure how to fix it. I know you were hoping for an answer (as am I) but thought I would just chime in to let you know someone else is also having this issue --- for what it's worth...
