Let´s start 2019 with some eosm love. The setting is called:
4K squeeze 24fps 
It´s working continuously with 10 bit and build files when set to 2.35:1 through crop_rec submenu that gives files sized to 4000x1704. The files are actually recorded into a squeezed mode(4000x696 or 4000x 568 when 2.35:1 is selected). Thanks to mlv metadata the upscaling is done with the default scale tag so it´s merely a question of opening up the file in Mlv App or acr and the unsqueezing will be done automatically.

To use it enable 'framing' to get a preview in liveview. It is working in regular video mode(NOT x3 zoom mode). Set bitrate to 10bit and ratio to 2.35:1 for continuous recording.
Please report back how it works and feel free to share content recorded.
By the way. Do not miss out on this progress!

Build for download in following post:

TODO:
Focus pixel map(dfort is looking into it).
This mode actually also works in mv720p which yield 5x1 squeeze. Will check if it´s actually useful in real life or not.

Sorry for off topic, but you are talking here :P

You're right, we hijacked the EOS-M topic, let's discuss further about binning in this topic:

I imagine it's that I'm doing something wrong, but I'm not getting much joy out of the latest 4k 3x1 squeeze.

I *think* I have the settings all correct, but mine are below:

Any pointers as to what I have set wrong? All I'm getting is pink screen/static in LV, even when set to framing.

cheers

Did you maximize resolution?
I'm about to put up another version soon but in short. If you want to film without jagged edges set your cam into mv720p mode (50fps) and in x5 mode when filming. (x5 might not work on this version, didn't check)
Will have an optimized build up soon that will work out all the quirks.

Disabling FPS override, definitely got me more usable liveview, but still lots of pink flashing.

I'll wait for Danne to upload the new build he mentioned, then give that a go!

4k 3x1 working as expected for me.  i tried to reproduce your problem and when i change the video mode in canon menu from 1920x1080 24p to 1280x720 50/60p, vertical purple lines scanning the frame from bottom to top occurs on framing liveview. i guess this is the result of a shutter speed problem that also occurs. shutter speed was "N/A" in magic lantern menu and global draw.

Changing video mode back to 1920x1080 didn't solve the issue by itself even if i reboot the camera. After setting the video mode 1920x1080 24/30p in canon menu, i press the info button and change the shutter speed there and that fixed this issue.

If your problem anything like that you can try this.

Ah ha!

Adjusting the shutterspeed back to 1/50 means that it now appears to be working as intended.

Will have a play and report anything else that I find back.

cheers

two simple questions:
1 wich EOS M model is better with ML?
2 wich is better for ML video 100d, 700d or EOS M?

New 4k version:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

Should be no jaggy edges in this one. Select the 4K 3x1 24fps preset. It should set you in x5 zoom mode but still keep the 4k settings. If not in x5 zoom just hit magnifying button to get there.

Please report how it goes...

EDIT:
Pixel peep
Old version:

New version:

Danne,

Can you make the same build for the 100D too?  Then I'll let you know how it goes.  Good stuff, by the way!

4K build works.
Is there some special way how to process it? When I use MLVAPP with default settings (3x vertical clearly works) i'm getting a lot of color artifacts (crop 100 %):



Also there seems to be an issue with exposure time, when i go to ~1/100 and faster, 5x zoom view starts flashing and framing view splits into several black and part of screen bands.

Thanks loknar. Reproduced. Not sure why faster shutter speeds causes this. Maybe some overhead issue.
Anyway. Expanded height to 750 so it starts in 16:9 as default. Use crop_rec submenu for 2:35.1.

Color artifacts and focus pixels. We´ll need dfort checking this.

New preset added:
mv1080p 1736x738 50fps

Means 50 fps in 2.35:1 with 3x3 binning mode. Works in both mv1080p or mv720p selected in canon menu.

Download here per usual:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

Really need people to test this preset for corruption. Did my best to tune in timers but might be borderline anyway. I run it with audio off and global draw to off in 10bit. Sd_uhs hack might interfere negatively on this preset. Also needs testing.

I captured about 1500 frames and 2 of them are corrupt - lower half pink and shifted sideways.
Also, longest shot was slightly above 11 seconds, it stopped after on screen message saying something about  "incorrect frame order".
I'll test some more.

I did some more tests
i'm getting ~250 frames without SD overclock (~35MB/s), ~ 550 with SD overclock (~44MB/s)
in second set corruption appeared only in shots with SD overclock (3 ouf of 550). Frame out of order didn't appear again.
As for global draw it's on, but i'm using canon liveview, does it count?
Disabled sound, like not loaded mlv_sound module?

Aaaand some more tests.
When not overclocked no corrupted frames.
Sound doesn't seem to cause problems.

Also i noticed it doesn't want to show dowm when button pressed (it stucks on "Sensor cleaning" and orange led on), needs two additional presses (one to start again asnd switch off)

With SD overclock and no sound it seems to prolong recording to some ~800 frames and no corruption
Sorry about first report, i  enabled sound module on autopilot.

Also, all these are low light situation no Sun here today.

Ran five 11 sec recordings with the 50 fps preset and couldn´t create a corrupted frame. Maybe fixed?

It now switches off okay.

For some reason i'm getting longer times 650-800 frames but unfortunately each clip contains 3-5 corrupted frames, not consequent in different parts of clips.

No corruption and length ~17 seconds shots, I only activated SD overclock, cropmode and set 10 bits in it.

Doesn't like overexposure and sudden changes in brightness, when light conditions don't change too much, it looks like it can be continuous (I have 21 second shot that I had to direct at light bulb in the end to make it stop [after several seconds]).

Btw does ML control over Image Stabilization in lens? I have IS activated in Canon menu, but in replay it says "no IS" (i use manual focus, but that shouldn't be a problem or is it?)

Cool.
No idea about image stabilisation in this case.

New build:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

Optimized 2520x1308 setting to 2520x1438(16:9). Works with real-time preview 24fps.

Also added a mv720p 50fps setting. Will record 1736x696 so unstretches in post to 16:9.

So utilising crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jan07.EOSM202

I manage to get both 50fps with mv1080 and the 4k-24fps.

With the 4k-24fps, I was getting a similar colour artefacts to Loknar. I.e. blue/yellow oddness. Seems to be concentrated around horizontal lines

Also overexposure or anywhere close gets pink highlights when exposure is brought down. Highlight reconstruction in MLVApp doesn't help, but Resolve highlight reconstruction does help, but only using MLVFS, which currently doesn't remove focus pixels.

Obviously preview is slow, but finding and maintaining focus is v. difficult.

With all that said, when you get the exposure right (ETTR) and grab focus the quality of the shot is excellent, but the horizontal artefacts are affecting things. Just want to be clear, I think it's Amazing to get 4k RAW out of a 6year old camera, but would like to get this to a great user experience so it could be used for actual project.s

50Fps seems to be working fine, with SD Overclock, I'm getting approx 10sec, but it was a bright scene, so I think that's what limits it due to data rate. But it looks good when slowed down to maybe 80/90fps in Premiere using optical flow.

I see that there is a Jan9 build, so will go on to try that and report back any findings. If MLVs would be helpful for the colour artefacting, just let me know

TA!
