I post this into the Post-processing forum, as there is no real pre-preprocessing forum:
I am wondering which are the processes done by the camera's processor for creating an 8bit video file:
As far as I understand it now, the following steps have to be done(or many more?), but which is the correct order?
CMOS Chip - Light detection: The matrix of G-R-G-B is read via a bayer sensor:
Camera Processing:
- De-bayering
- Converting 14bit raw to 8bit (how is this done in detail?, is it only clipping or something like tone-mapping?)
- transferring image data the linear light to log (gamma)
- Adding the canon pictures style - presets (after or before the conversion to 8bit )
- Image optimizations (which ones do exist) sharpening process, ...
- Data transform to YcbCr
- Chroma subsampling process (4:4:4 to 4:2:0)
- Transferring the series of images into a movie container: Quicktime
- movie compressing: inter- and/or intra-frame (mpg4, h264)
At which stage are the canon picture styles embedded?
Can I influence with the canon picture styles the conversion from 14bit raw to 8bit?
Thanks for any suggestions or ideas !
