Render Cache - What is it?

One other thing... I'm pretty sure that these files take up some RAM... so adding more RAM might also help with this.

I make it a habit to regularly throw away renders from old sequences for precisely the ram issue.

My workflow is to duplicate a sequence and give it the next number up (Show cut 6 becomes Show cut 7) whenever I'm about to do anything "drastic" to it, like a major re-arrange, or doing something else funky, where if I screw up I can go back to where I started. Eventually, i'll have a bunch of versions that have usually been completely re-rendered, making all the old renders obsolete. But they're still there in RAM, because FCP has to remember EVERYTHING. and then I every now and again make a "snapshot copy" of a project file as an archive, and chuck all the old sequences for the same reason. Keeps the project files snappy. And you can always open the snapshot and drag over anything you find you might need after all.

Just to provide a counter-point, I do the total opposite.

In my previous working environment, I never trashed render files - unless I exported to Compressor - even though I constantly ended up re-rendering or rendering additional portions of my timeline(s) (not the most efficient way to work, but that's how it ended up being). I usually kept 4-5 sequences open at all times, and most with nested sequences. (And, on Fridays, I used to have my project file open for 12+ hours straight, so never did I flush the queue in that way)

I've never encountered this and I'm on a G4 with 2GB of RAM (nothing compared to the 4+ GB that all you G5 boys seem to be rockin' nowadays 🙂

But, in defense of the current favorite theory, I keep my undo number at the default 10. I take it most of you bump your undos up a lil' bit? 20? 50?

ah... if you keep more undo's available, makes sense that it uses a lot more RAM up...

I used to keep undos set to a big number, but I've dropped it to 10 or 15 since I discovered the "law of undoing"

"No matter what number you have set for undo's, you'll always need one more."

Isn't that the one you reach for right after sinking the 8=ball?

If you set your auto-save for 10 or 15 minutes, by the time you need 15+ undo's you're better off returning to the project from 10 minutes ago.

That's a bit of an anti-climax! 🙂

Well, it's possible your client just got it wrong and there is no such thing as the render cache...
