Avoid the 32-bit-per-channel slowdown

If there's one thing I've wanted you to get about working in 32 bit HDR mode, it's that when you're creating these kind of over range elements this is the fastest way to get a really nice result. The irony is many artists avoid working in this mode at all because it's perceived to be slow. So, here's a quick quiz. If I change my bit depth to 16, how much faster does After Effects render it? Two times? What about at eight? Is it four times faster? I'll create a 30 frame preview of this particular movie. And just try it again at eight bits. Now, I don't expect you to be timing this at home, but I timed it. And the difference is about 15%. Now, I'll grant you, this is a single layer that's been taken to over range, so really, this isn't like testing an entire elaborate project full of over range values moving up and down. But if you've experienced 32 bit per channel being a slow mode, you may have been working with a much older version of After Effects. It's been optimized over time…
