In particular, how do I set up, run and process the full Res 'photo mode'. Once I know how to get things running, I can test.
Simplest way:
- crop_rec.mo, silent.mo
- crop mode: full-res LV; silent mode: simple, any file format
- press half-shutter
- for preview, also load
mlv_lite.mo mlv_rec.mo, enable raw recording and global draw.
- you can review 14-bit regular/lossless DNG (pic_view) or MLV (mlv_play); for 10-bit full-res MLV, raw_twk runs out of RAM
Continuous full-res recording at 4-5 FPS:
- crop_rec.mo, mlv_lite.mo
- crop mode: full-res LV; raw recording: max resolution, lossless compression
- FPS override: 4 or 5 FPS, low light (important)
- press record
- mlv_dump foobar.mlv --dng
Fast half-shutter trigger (with negative shutter lag):
- crop_rec.mo, mlv_lite.mo, configured as above
- raw recording: enable REC trigger (half-shutter: pre only; without pre-recording enabled, that means only 1 frame)
- no need to use FPS override, as we are only saving the frames triggered by half-shutter
- start recording
- press half-shutter every now and then to capture a frame
- stop recording
Capture unpredictable action (animals, kids etc):
- crop_rec.mo, mlv_lite.mo
- crop mode: full-res LV or 4K half-FPS
- raw recording: max res, 10-bit (here, pre-recording is a bit confused by variable frame sizes, so let's not be adventurous)
- pre-recording: 1 or 2 seconds (actually "up to")
- half-shutter trigger: "hold" (which will pre-buffer up to about half of available RAM), or "pre only" (which will pre-buffer all the available RAM)
- start recording, press half-shutter etc
- caveat: preview is not working at all with 10-bit (try 14-bit)
- to review in camera: 4K 10-bit can be played back with mlv_play + raw_twk, full-res 14-bit with mlv_play only.
I believe this has already been said, but the best way to use the lossless 14bits is to forget to shoot in ETTR.
Do you think there is way to take the control on the compression codec ?
Very little.I wonder if there is a potential for ordinary resolution recording but with higher frame rates.
First post:
* 1920x960 @ 50p (both 1:1 crop and full-frame - 3x3 pixel binning)
* 1920x800 @ 60p (same as above)
* 1920x1080 @ 45p and 48p (3x3 binning)
In particular, 1080p48 is quite pushed to the limit, which is why I've also included a 45p preset (hopefully a bit more reliable).
1/ 1080x1080 (from 3x3 bining using the 3240x3240 sensor size). for a big anamorphic s65 lens.
Already possible on regular nightly.
2 / in the same way of the 14 bit losless mjpeg compression is an 8 bit mjpeg compression possible?
Yes... so we can do low file size and get the real sharpness the 5d3 can offer (clean HDMI recorder on prores does not get any better sharpness than the in camera h264 file - whereas the raw files is always resolving much more sharpness)
... but it would simply compress Canon's YUV422 buffer (with their color science, picture styles, sharpness etc).
3/ finally how far would you say you are from a working preview for the mode 3K, UHD, or zoom x5 and is it even possible?
Far, far away. The trick I've used to center the 5x zoom preview in the regular (non-4K) crop_rec branch didn't work for the new modes

Also, I have no idea how to configure image scaling. Adtg_gui doesn't reveal any difference between x5 and x10 zoom modes (both use identical raw buffer configurations - just the preview differs).
I can try to include the centered x5 zoom mode (which you can already use in the "classic" crop_rec builds), if that helps.
