I think that is every animator's goal.

I don't know "extreme", but normal and high are standard. High gives
better compression and better resolution at the expense of CPU power.
These days, I see no reason to use normal. (High was for the original

I see. Yes, 10 FPS is definitely choppy speed. You can go as low as 20
FPS (23.976 is Blu-Ray speed) and look ok.

That would be an interesting experiment.
My wild guess is an 80% larger file. 3x the frames but 50% is black.
If you are comfortable with the command line, you should try ffmpeg.
It's pretty much the standard these days.

Aren't we all.
You seem to have a good handle on what you're doing. That puts you
light years ahead of (100 - ℓP)% of people.

I would be very interested in seeing your vid with a higher frame rate. :)
