Can anyone tell me how this is possible (bitrate) in a 600D, which sd slot is limited to only 21,9 MB/s?
I'm recording 3x crop mode in CBR 3.0x (SanDisk 95MB/s).

Oohh yeah ... sorry for my ignorance. Anyway, he came to 25MB/s (100Mbits/s / 4 = 25MBytes/s), whereas in Benckmark made ​​only 21.8MB/s. I do not understand these limitations ...

Because there is 8 bits in a byte, not four.

Oww... that is.  :-[
So, this means that H.264 does more than 12.5MB/s?
This is a disaster  :(
