Well, since you've neglected to say what your critria are for
"best", you're going to get useless answers.
I say "best" is 480x480 with 3:2 aspect ratio with 2200 avg
and 6600 max KBPS.

Actually, I thought that a '250 would only capture in 480x480
3:2 mode?

Are you still asking about capture resolution?

Only if you tell it to transcode.

"Optimal" varies depending on criteria.
