We would argue that 2GB is a bit too low. ;)

Distribution format (H.264 ) = 2-3MB/s (4:2:0 8-bit)
Post format (CineForm) = 10-16MB/s (4:2:2 10-bit)
Uncompressed = 124MB/s (4:2:2 10-bit)

CineForm is a post solution for those not wanting the burdens of uncompressed, yet wanting the quality.

So then by your statement if I recorded the AVCHD at 24MB/s Im loosing data but gaining color space by using CF? Sorry about not quite getting it. Why do you say CF 10-16MB/s when it says AVI at 109 Mbps here?

You are confusing bits and bytes. Bits = 'b' Bytes = 'B' So 109Mbs = 13.6MB/s (divide by 8).

CineForm can't restore the data lost in your source, but it can prevent you losing more while it improves the performance and adds to your workflow options.
