Is there any reason to capture RGB over YUV?

[Bulletproof]

I have read that YUV is mathematically equivalent to RGB, so is there any reason why someone would use RGB?

I don't know about this, but I remember that capturing in RGB helped avoiding field problems.

But you probably want to use YUY2 anyway, since this is the format the BT8x8 chips use.
