I can't figure out what "frame blending" is supposed to be. The fact that it's a *checkbox* makes it even stranger. It's either on or off. How does this differ from "motion blur" (is it just a synonym?) and why is it not an effect you put in the timeline but a boolean on/off option when exporting?
I did read the pop-up summary when hovering the option. It does explain it somewhat, but doesn't really answer my questions.
There are two frameblending options:
1. on a clip: this smoothes out motion when the speed of the clip has been altered as said before.
2. in export: this should be checked when the export framerate differs from the sequence framerate. If the source and destination frame rates are the same, it will have no effect.
silly people with a silly request.
Heh, heh. I was one of them. (We're talking back in 2007.) I didn't like the default (particularly for what I was doing at the time), and I think it was not possible under some conditions to avoid it.
Example: some slow-mo benefits from interpolated frames and a bit of blur. But when you are looking to get crisp looks in between, you don't want frame blending. And for some animation subjects (think import from After Effects) it was a problem. Sorry; don't remember now why it was not as simple as turning it off. Like lots of things now, I'd like a toggle to control the default (on or off).
