Could double digic processors on the 7D provide any help with this new RAW findings?

Canon's encoder uses the bare minimum subset of H.264 in order to say they use H.264. No B-frames, no CABAC compression, only one reference frame... and worst of all, no adaptive quantization, which spends bits in areas that needs them the most.
Makes sense. Thanks for the explanation.

I guess you are not recording something that has enough detail to achieve the highest possible bitrate. Try to use f5.6 - f8 with high ISO and something like beach sand, grass, trees...

Tried with Sandisk Extreme CF with no issues at x20. Crisp detail improvement is AMAZING, but for any reason, soft detail looks very close to Canon's default bitrate (blocky). Can't decide between regular mode or ALL-I. Can't wait to go home and do more testing.

It stills drive me crazy that a 25mbps HDV looks better in detail and compression artifacts than a Canon's 50mpbs+ H.264.
Is this beacuse of the encoder Canon uses? settings?

Ok, thanks for the answers. It was just a wild idea.

Can't wait to adjust 7D bitrate, then.  :)

Regarding bitrate and cropmarks, I was wondering if it would be useful for example to have the option to record only the 2.35:1 frame area, and keep the rest black. That could improve bitrate efficency.

In any case, ML is an amazing work, BIG thanks and keep going.
