Color is a fantastic tool. But it also works like a broken down wheelbarrow half the time. When it does work, it’s a thing of beauty. Effortless color correction on a desktop mac. When it doesn’t work properly, it sucks time like you wouldn’t believe out of your day. I can color correct an entire act in about 3 hours. But it often takes about 3 hours just to get one or two bugs ironed out and worked-around. I’m currently trying to figure out why it won’t let me render in my original settings for one particular sequence, whereas it would for 2 identically created ones. No real reason is given, it’s usually a problem with some file on your timeline… which you then have to hunt down and find.
In this case, it was a few clips of animation compressed footage that was throwing it off. Simple stuff, but it takes a lot of time to make sure it doesn’t do something crazy.
