Canon EOS M - Early Spring

I did some tests using experimental sh_uhs.mod module and this is the result.

Wow, shot at "2520x1072(2.35:1)@24 fps in 12-bit lossless compression (55 MB/s bandwidth)." So I take it you're getting continuous recording with the sd_uhs module? "70 MB/s instead of 40 MB/s."

3K raw video on an EOSM, nice! Looks like we can go even higher resolution on these cameras.

Yes,  most of the time, thanks to ML developers, in this case specifically @a1ex and you.

That looks very promising and interesting.

Wow, that's brilliant!!!
I've got an important question, Loknar. What is the crop factor in the case of the resolution you used?

Compared to 35 mm camera, crop is 3.4. I have Canon 15-45 and most of the time i used it at 15 mm so it results into 51 mm.

This is awesome. I tested my eosm with the hack and it delivers 12bit continuous in 3xzoom mode 2520k. Gonna try some material with my 10-20 f3.5 sigma today.

That's fabulous, thank you!
Is there a way to put hands on a built module?  :P

It is part of this dfort's build: https://bitbucket.org/daniel_fort/magic-lantern/downloads/crop_rec_4k_mlv_lite_snd.2018Apr03.EOSM202.zip
But be advised, it might be dangerous to your card and/or camera.

Check the sd_uhs thread. By the way teamsleepkid. What card are you using?

Could you try and report this build @Teamsleepkid:
https://bitbucket.org/Dannephoto/magic-lantern/downloads/magiclantern-Nightly.2018Apr17.EOSM202_sd_uhs.zip

Go into DEBUG menu and press SD overclock option. Do it in photo mode. After the test is done you switch to movie mode and start recording. Would be good if you could report what your best numbers are after the test is done to see what frequency your card will be using. Hopefully 160mhz around 50-60mb/s. Or more...

The build provided contains Alex latest sd_uhs code but do not blame me if anything strange happens :).
