Render space issue w/ letterboxed anamorphic footage
Hello All,
I’m getting an “Insufficient Disk Space” message when I try to render a ~40 minute sequence filled with letterboxed anamorphic footage. The weird thing is that my scratch disk has 79 Gigs free. Could the render files really be that big, or is FCP (4.5) just going bonkers on me? Should I trash my preferences?
Thanks in advance for any thoughts anyone has on this,
Rachel -

Depends on what codec, frame rate, and resolution you are using…
This fee app will help you do the calculations:

thanks! i’ll do the calculations.

Actually, it turns out that app just calculates media storage space, not the space that the render files should take up. Any other ideas?

I’m sorry, I misread your post, I thought you were exporting, not rendering, although if your whole sequence needs to be rendered it’s just like exporting the whole thing.
What resoltuion and frame rate are you working in?

If you are in 10 bit (and probably even 8 bit) and you have to render your entire sequence for some reasons that you aren’t mentioning, like you have a widescreen filter to make the letterbox, or perhaps you don’t have the anamorphic settings correct and FCP is doing the heavy lifting on your anamorphic sd footage requiring a render or heavy graphics/text/cc/composting, 79 gigs might not be enough. Free up some space if you can. A good way to start is to quit FCP and go to your scratch disk and see how big the render files folder is for that project your are working on. Deleting render files is a good and safe way to gain some much needed space on your hard drive. Be warned that once they are deleted and you open FCP again, you will need to rerender. You can also use the render manager in the tools menu to delete render files as well.

Thanks so much for your help! Here’s the deal–I’ve now got about 10 minutes’ worth left to render in this sequence. For some reason, the computer is letting me render in smaller sections but it still won’t let me render the whole thing at once. I’ve still got 77 gigs of scratch disk space available, and the last section i rendered was 2 minutes long and took up less than a gig. There’s one two minute section (and there may be more sections like this) that gives me the “insufficient disk space” message, but there’s nothing fancy about it in terms of filters, in fact it’s simpler than some of the other sections b/c it doesn’t have a color correction filter on it.
I already trashed my preferences and reset my scratch disk. Someone else on another forum said my hard disk permissions might be messed up, which i would repair, but i don’t have OSX installed on that disk, and you need to have it installed to repair them. Do you think i should install it?

No, you shouldn’t put osx on your scratch disk, but you can still repair permissions your boot disk that has OSX. Quit FCP and do that, but I doubt that’s the issue here.
Did you delete your render files? Perhaps something is fouled up in one of the old render files.
If there’s nothing special about the clip that gives you the message, then why does it have to render?

The green preview bar shows up above it in the sequence. It is letterboxed anamorphic footage (like the entire rest of the sequence), but it doesn’t have a widescreen filter applied to it. It’s just footage that was shot anamorphically but that is in a 4:3 sequence.
