H246 is to send in an e-mail, it affects the colors a lot.
Animation is good but not perfect,
Photojpeg I don’t know, but it is compression.
If you need to rerender everything later, you should consider
none, or no compression, If the movies go to Final cut,
uncompressed 8/10 bits is a good option.
(Sounds like no compression, but it is compressed; it’s half the size of no compression)
I don’t know how much you have to do, but firewire discs go very cheap these days…
