For 650d you could try the build posted by me on page 18 of this topic (Reply #446 on: July 02, 2020, 01:58:05 PM)

The module in that post should work on 650d in combination with crop_rec_4K build from the experimental builds downloadpage on this site.

It works on 650D!

Everything started the first time on the "crop_rec_4k" firmware.
Results 60 MB/s before recording clips. I recorded two clips in ~ 1 minute in 14bit Losless. During recording, the indicator was always green, occasionally yellow. Recording did not stop even when moving the camera (previously interrupted).
After stopping the recording and restarting the camera, I made another benchmark. Result 65MB/s!

Сard: SanDisk Extreme Pro 128GB, 95/170 MB/s

I think this is enough for me so far) Thank you guys!

Link to this firmware (for 650D):

I also wanted to know. How to focus pixel map files (updated) translate to MLVProducer (Win10)? Type .pmm

In the description of the video left shooting options.

Good! Thank you, Danne and other guys!
This version is better - benchmark 55Mb / s
1) It is necessary to pre-select the points CropMode and RawVideo. And then run the script.
2) Preview is very tightly compressed horizontally. In the previous version of the preview with low FPS, but with normal proportions. I think this is more important - the right proportions.

I can still test something. Only in programming I do not understand)

I tried the last two versions of the firmware. Record 5k works (non-stop). But not always. 2-3 failed attempts (recording stops) and then it can work normally.
I also checked the speed with benchmarking - 46 Mb / s maximum. SanDisc ExtremePRO 95Mb/s, 64Gb memory card.
By the link photo settings and errors:

I also tried using the [SDoverclock] script - I can’t overclock the SDcard.

Script from this firmware:
The script and module from EOS M allow you to overclock the card up to 55 Mb / s.
Also from there are working skript:
- 2.5k10b100
- 2.5k10b800
- 1080p12b100
- 1080p12b800

And I could still set my resolution (down).
