Thank you for adding support to the SL2, I recently installed the program and ordered a 128gb 300mb/s SD card because the lower write cards limit the program. How do I send you guys information as I test my results to help make improvements?

Thank you for your attention.

This cam is not limited by the card itself, it is limited by the card interface.

You will gain no benefit with a UHS-II card, the cam only supports UHS-I.

Currently it is not possible to get a higher write speed than about 60 or 65MB/s.

Thank you for that information. I was experimenting with 14 bit, but it would stop. In 10 bit I'm able to get 2008 x 460. Depending on the aspect ratio it seems to work fine. I thought I might be able to get up to 4K. I am extremely satisfied with the new performance for color grading. My only concern is that I can only make adjustments like ISO, frame rate, viewing the histogram from the original screen, then have to hit info until the raw recording screen appears. there is no over lay.

just a side question, do you know if ML will ever address old drone cameras. I have a Mavic 2 pro and it does not have 4K 60fps. I've always thought that frame rate was possible, because it offers 2K 60fps.

The card write rate limits you.  As you push resolution higher, you need more speed.  Required data rate is:

X * Y * fps * bit depth / 8, as bytes/s, divide by 1024 * 1024 to get MB/s.

200D is currently limited to about 60MB/s write (maybe 65...  further real testing by users required).

I would expect significant loss of image quality at 10 bit.  My guess is that 12 bit will be the sweet spot.  I expect 14 bit will be useful when using low ISO.  But I don't have the image processing experience to test these guesses :)

ML is closely tied to the OS Canon uses.  It will only run on Canon devices.

Adding to the injury: Fastest UHS-II cards may not deliver outstanding results in UHS-I mode.
Too many Canon cameras.
If you have a dead R or RP mainboard (e.g. after camera repair) and want to donate for experiments, I'll cover shipping costs.
