Hey Rafael. How are ya?

It’s a new thing that appeared in FCP6. I really don’t know what it does for sure, but since you ask, I’ll give you my best educated guess. it seems to be a still store cache that references certain media frames in FCP for different frame sizes and frame rates. If you open one of the constant frames, you will notice that sometimes the file size is small (like 12k) but the movie reports a duration of 56 minutes. SO it seems to be a QT reference file that points to a still frame or series of still frames. The ‘Unrendered’ tag comes up quite a bit as do slugs for various frame size and frame rates of differing sizes, depending on what the editor has been working on lately. Sometimes, they seem to go corrupt (?) and turns files green. Trashing them sometimes fixes it, sometimes not.

So that’s my educated, but not quite sure guesstimation. Weird, eh?

Thanks Jeremy. That makes sense. The FC manual don’t even mention the “constant frame”.
BTW. Are you using Color? have you see the strange “-C” file that grows (few GBs) on top of the Applications folder , in the root of the System HD?
Is something weird. If you try to open it, its replicates it self.

No. Does the strange file have a .app suffix by chance?

No extension, nothing: -C
Is a very strange issue of Color.
If you let Color “auto-save”, this file doesn’t appear.
In the moment you save by Comm-S you see two strange processes in the Activity Monitor.
A “gzip” and a “tar”. The ball spins for several minutes and the “-C” file stars to grow and grow.
I’ve just rendered a 4 seconds clip, and I get a 2.6 GB file.
When you double clic the file after a very long time “Unarchiving -C”, you get a -C2 file beside.
And the “-C2” file start to expand it self and in the end, when you think you will get a “-C3”, just disappear.
I thought that the issue could be because I’m working with EX-1, but it happens with every kind of footage.
This is happening to a lot of people.

Hi again Jeremy,
While I was posting you, I made a little test with Color.
The -C file have grown.
Double click: The “-C” file have generated a “-C2” file.
The “-C2” file have started to expand it self.
When finished, the “-C2” have disappeared but I’ve got a “Users 2” folder.
Inside I have the same folders structure: Users>Rafael>Documents>Color Documents.
And inside all the Colors documents: Projects, Media, Renders.
Very strange. Color is duplicating and packing all his own folder.

Nope, Constant Frames have been around since at least FCP5. The Constant Frames folder is where still images and generators are cached ( to improve playback performance ).

Thanks for the correction.
