HOW DO I FIX THIS?

It's about the same (compresses somewhat more than huffyuv and somewhat less than lagarith), but it's meant to be much faster and thus better for editing more than anything, but on OSX it isn't optimized yet so at the current state it's Slow As F**k.

Actually if you use it via Perian instead of QTC directly, it should be significantly faster, assuming your Perian build has the new threading stuff (which I am assuming has been committed). Optimisation is currently underway upstream tho, and I have a bit of asm written somewhere.

Huffy is always gonna be shit for compression tho, if you wan't better, then use a better codec. Should be able to do FFV1 in OSX.
