My issue is purely between the transition from clip to clip. If I play a clip in clip mode, it plays absolutely no problem on any quality. As soon as I try to play in movie mode, even on low quality, the video freezes and the program locks up for a few seconds (while the audio continues). This is in a brand new project with zero effects or editing aside from adding multiple clips in.
Previously, I've worked on a few more complicated projects for the past month or so with zero issues with high quality playback.. and now all of a sudden it won't play even on low quality. My projects consist of many many short 1-5 second clips put together, so needless to say it's made it impossible to do my work currently unless I'm doing clip by clip. If I bring up my performance graphs during a freeze up.. my computer isn't even doing anything, it's not like it's overloading or anything.
Does it have something to do with temp files building up? Or something? As I said I've had zero issues in the past.
I'm running i7, 8 Gb RAM, x64 win7, HD Radeon 5450 just updated. Quicktime up to date, windows up to date, etc.
