Re: Out of Memory Error... FCP 7... project too large?

There's more than one reason this could be happening but here's some thoughts:

That's a really large project file. I'd brake it down a bit. Having open sequences that contain a lot of edits can bring your computer to it's knees. The more sequences you keep the worse this gets too. FCP can only address about 2.7 gigs of RAM in any event.

Photoshop files that contain blank layers can cause this error message all by themselves...

Bad Media files might be at fault. Render files are usually the culprits if this hasn't happened because of a Photoshop file being added to the project file...

But my guts really say your real problem is the size of the project file. One thing you shouldn't do is keep copy upon copy of your sequences. Backup your project files instead. Having a lot of clips usually isn't what makes the project file so large, it's piles of sequences, and text files in them that enlarges them the most. Text generated files are actually stored in the project file itself where media is not...
