Could someone who knows the internals of the camera explain the ProRes "filimic" mode and how it differs from the ProRes "video" mode.
I was told at NAB specifically that the ProRes was a codec that had 2 NON-LINEAR/NON-LOG (Filmic and REC709) gammas optimally pulled from the 16-bit LOG RAW data converted from the sensor.
Filmic I assumed was either for conversion to film or to make video look more like film. (Forgot to ask.) In other words, it was like Panasonic's non-REC709 modes. Either it made the video look like it was shot film or it was very flat and was used for conversion to film. In the latter case it needed a special monitor mode. And, because it was so flat, it would look much like logC footage even though it was NOT log data.
There is also the view that BM really has applied 10-bit log conversion (logC?) to the 16-bit sensor data so the Filimic mode matches the RAW mode in DR, but has been compressed. A killer feature!
If this is correct, does only the ProRes codec get log data?
If this is correct, what is BM recommending -- other than Resolve (assuming it has a ProRes UN-log mode) -- to handle the log data. (And, yes on can unconvert log in any CC by applying the correct conversion.) FCP also has log plug-ins.
But, first we need the facts about the "Filimic" mode. And, a sample would be great!
