Hm... I now tried crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Feb02.EOSM202.zip and get still the same.

Yes, I am going through ML menu. And it looks good and I can record in those presets as long I don't touch the shutter button. If I press shutter half way, lievview fails completely.

mv720 has wrong aspect ratio with framing preview, therefor shutter button works correctly.

Thanks for mv720p check. Will fix the framing preview later for this mode but it's preferred to use real time preview with high fps modes or even global draw off.
Ok, so let's try and clarify each preset:
- 2.5(x5) will work with framing and real time preview while recording and while idle. Real time will be cropped when halfshutter is pushed.
- 3k and 4k presets(x5) will work with framing and real time(cropped) while idle. When recording only framing works. Pushing halshutter will break preview while recording.
- 3x1 4k and 3x1 5k (x5). Only framing works. Pushing halfshutter breaks preview.
-mv1080p(3×3) same as 2.5k
-45, 46, 48, 50fps mv1080p and mv720p works same as 2.5k(first preset).
-5k anamorphic. Default works as 3k, 4k but 2.35:1 and 16:9 works as 2.5k(first preset)

I agree, if "will be cropped" = "will be broken" and "cropped" = "broken"; for 2.5K, 3K, 4K. I formatted another card and did a fresh install. Still the same. And ISO100 doesn't help this time... LOL

Great.
So 3k, 4k. Also broken when used with framing on? That is when recording not using halfshutter.

Mv720p mode. Try set preview to real-time for correct preview.

Sorry i understand not correct first time, now retest and yes i'ts work when press hulfshutter. Preview broken only when recording.
Try real time in 720p with global draw off and yes it's work corrupted frames free.
Thank you Danne for your work

Good, works as expected in your case then :).

Fix for mv720p if using framing preview(Global draw off recommended though)
Also added a compression reduction line in mlv_lite.c that might or might not help against corruption. We,ll see.

Masc! Reproduced your issue. Set focus to manual or change the middle af-method setting to the bottom setting. The other two seems to break the party completely. I recommend manual focus dude  :P.
Phew, hard to nail this one.

Haha... ok. Nice found Danne... hey, this time it wasn't ISO setting! :P
AF method plays no role here, but indeed with MF it works fine! With that I can work for now! :) Big thank you!

Hi everyone. I've been thinking about purchasing the eos m to use in crop mode with c mount lenses for a long time, but the wonky live view always deterred me. It seems from Danne's post that this is fixed now. Is that right? Is there a real time, correctly framed live view in the 5x crop mode now? Thanks

Loading the 1080 12bit script and changing to 10bit seems to get rid of pink highlights? I may have changed something else, but I’m sure changing the bit helped.

Please upload sample mlv files. Mixing bits from raw video setting which that script is adding and then adding 10bit in crop rec submenu won't work with most presets but unclear what you did. It could even be that you changed iso from 100 to 400 that clears the issue since it seems the pink issue happens on iso 100.

Changing bitdepth can't change behavior of clipped highlights. Pink highlights will be there if green sensor channel is overexposed. I explained that already here: https://www.magiclantern.fm/forum/index.php?topic=9741.msg211249#msg211249

It was the iso 800 preset, so if it only happens at 100 that explains it.

Curious to see a sample as well.

That’s a good possibility.

The pink highlights have vanished, buuuut I was successful in recording 555 frames of 2.5k.  Keep up the good work!

Nothing changed regarding white level in later builds. Pink fix still needs attention and testing.

I did not understand yet, why in different clips I have to set different white levels to eliminate the pink. I would expect an equal value for equal settings.

Using C-mount lenses on the EOSM has been discussed several times on the forum. If you use Movie crop mode you'll get real time, correctly framed LiveView. The wonky LiveView is happening with the experimental high resolution crop_rec module settings that can use the entire sensor area. So--if you think about it, many C-mount lenses won't cover the entire APS-C sensor so you can't use them with these experimental settings unless this is what you're after:

I didn’t think it had, so I’m guessing I had settings overlapping that was creating the issue, when I tried to recreate it last night I couldn’t.  I’m just happy with how fast the stability is improving.

- Cleaned out scripts, kept two. One is new. "eosm cinema 2:35.1". The script will through lua add all necessary parameters to get into anamorphic 4.5K preset. Once the script has finished you can use any of the crop rec presets and they will all run in 2:35.1 and continuous. A fast sd card will be needed. The script also enables the sd_uhs script "sd overclock engine" and sets it to auto. The script is good as starting point instead of fiddling around for 10 minutes before getting into filming.
Why 2:35.1? Easy. Eosm has it´s limitations and restriction and this ratio seems like sweet spot for most presets on this cam.



- The other feature(also added though "eosm cinema 2:35.1" script) is "Crop rec preview" in mlv_lite menu. Once this is set to auto mode The crop rec presets will work either with framing or real time preview depending on what works better. Reason for this is that it takes a little too long to switch both preset and preview mode for every preset changed. Watch out. This auto mode setting overrides any Preview mode setting aready set from before. Disable auto mode when not in use.
All modes and settings can of course be set manually without the scripts.



All of this is of course experimental, bleeding edge and out here for tests and feedback. As always thanks to a1ex, g3gg0, dmilligan for code and lua api.

Amazing build. Trying with a 4K monitor and it's unbelievable that it's anamorphic and not native 4K. Amazing work. thanks so much

Great. Hopefully useful now. I tend to use 4.5k anamorphic and 48fps mostly atm.
