Out of memory errors
August 03, 2017 06:28AM
Been recently getting a lot of "Out of memory" errors recently.
One project file in particular seems to be the most prone, it is a sizable project file, 200mb.
All media and project file are connected via an external usb3 drive that is 80% full.

Wondering what is the cause and solution? I do have 24gb of Ram.

your project size is very big for FCP
i would start by reducing it

do you have lots of older versions of edits in there?
copying them into another project would be the simplest way to reduce your project size.

the next step if that doesn't reduce it enough would be to split the project into more than one part.

lupacexi's question is verbatim a question posted in this forum two years ago.

So lupacexi is a jokester. "lupacexi" gets 6,500 hits in Google search. It's an online thing.

project size it pretty large.
too large, really.
you should look into splitting it.

what sort of media are you working with?
how complex are your timelines?

do you work with lots of sequences open?
that'll contribute

Nick's answer today is not verbatim, but admirably consistent, if wasted.

Wow, thanks Dennis.
How did you figure that out ?
And more to the point, what possible benefit do they get out doing that?

There's an acknowledged maximum project file size. I want to say it is 70mb but I see where some say 100mb. In addition FCP7 can throw that error when it runs out of graphic card memory. Which may require some flattening to keep you from going crazy.

Acknowledged by whom? We recently finished a half-year FCP7 project here with final filesize 139 MB without incident. In a topic from 2014, Derek Mok wrote:

I'd only start suspecting an overlarge project file around the 150MB mark or so.

It's the project complexity -- really its complexity when open in a certain state -- that the program succumbs to. The filesize does not measure this complexity.

It might be fun to experiment with how FCP7 manages memory -- how much of a project it puts into memory? Is it like the size of the .xml for the sequence presently selected? Or the .xml's for all the sequences open? Or the .xml's for all the sequences in the project? Or more? Or less? A 31x31x31 3D LUT is a huge filter. The .xml for a sequence grows by about 1.7 MB for each application of this filter. The project file only grows by about 200 KB; we can presume that the memory requirement is between those values. By this technique you can grow a sequence to great complexity in order to test FCP7s memory management.
