Post by: JPHILF on December 17, 2018, 10:20:29 PM
Hy, I've just installed ML 1.2.3 on my Canon 5D marck III. I have installed Raw module form the modules menu. No crop module is present in the list of modules.
The oprion Crop video is not present in the camera menu. I just can use RAW.
Can you help me?
Thanks

Are you using the crop_rec_4k build from the experiments download page?

OK, thanks, I found it.
But now, how can I shoot in 1920x1080 in 50p?
Which config?
If I try Cropmode = 1920 50/60 3x3  and raw=on 1920x1080, if I rec, it automatlcly stop after 5 sec

You can't. Please check possible resolution/frame rate combinations in the link provided by dfort.
1080p50 not supported.

You have to use a very fast CF-card, reduce bit depth and/or use lossless compression.

Uncompressed 1080p48 recording would require about
11.9 MB/s x bit depth
-> 10 bit without compression (119 MByte/s) continuously is out of the question.

You can even set bitrate from a submenu like on this camera:
