In the magic lantern menu, I'm using the "real-time preview" option under the Raw video options (selectable under the Preview options). This gives me the correct framing (including correct aspect ratio) in live view if I press the "info" button on the camera a couple times until the magic lantern overlay appears. Also Global draw has to be enabled - ensure that's switched on in the magic lantern menu.
I'm doing this with the Movie crop mode enabled (i.e. the "600D style movie-crop mode"). If you try this with another crop mode, you won't get the correct framing.

Thank you so much.  Yes, it worked perfectly. I converted my crop MLV into a .mov with the first try.  FYI there is now have a '14' version out there.  For me, this workflow is better than the MLVFS track.  I use Resolve, but I also use Vegas Pro Edit too, because it is so quick and easy.  After using MLV App and exporting as .mov, I can import the file into either one and go from there.  

You can record 1376x1030 (4:3) 12-bit lossless continuously on the EOS-M in Movie crop mode no problem (or 14-bit lossless though that may reintroduce focus pixels). In fact you can record any resolution and aspect ratio with magic lantern, the limit is the camera's write speed. You can go even go up to 1440x1078 with the 5x zoom function as mentioned in the first post here (that's different to Movie crop mode) - though I haven't tested that yet.
In terms of recording time with 1800x1024 12 bit-lossless, I'm getting between 10 seconds (very worst case) to 1 minute or so. Just tested it again and actually it seems that the amount of contrast in an image affects record times more than anything. If you want better record times in 12 bit, probably best to lower the res to 1792x1008 or so.
Also I've just started using another program to convert MLVs to cdng files which has a very nice interface and features: https://ilia3101.github.io/MLV-App/   it was suggested by this youtube user: https://www.youtube.com/watch?v=_yXb2bt8l60
I definitely miss my old BMPCC too. For sure the XC10 is much more ideal for normal HD filming than the EOS-M will ever be, but still the EOS-M isn't too bad for a camera that costs about £100.

Here’s a video showing a little rig. If you add a handle to the bottom, it would have that Super 8 camera feel. 
 

I've been playing half-heartedly with ML on my EOS-M for a while but in general lost interest due to annoyances such as the focus pixels, low resolution and workflow. However, inspired by recently released footage from Kodak's new Super-8 camera and fond memories of playing with real Super-8 footage in art school, I decided to mess around with the EOS-M again to see how close I could get to the Super-8 aesthetic. Turns out I surprised myself!

I've only shot a few early tests so far but the following video is, I think, very usable as a digital Super-8 stand-in. The basic specs are as follows:

4:3 ratio (like Super-8) 
1440 x 1078 resolution (plenty for Super-8)
18fps (same as consumer Super-8)
12-bit Lossless RAW (continuous!)
5x zoom (haven't accurately calculated crop factor/sensor size in relation to Super-8 yet - would appreciate help with this)
3X3 Crop mode (Experimental build: magiclantern-crop_rec_4k.2017Dec19.EOSM202)
Also- no focus pixels! (I have no idea why this is. They reappear if you go up to 14bit lossless or use any of the standard 10/12/14-bit modes). 

Below are two versions of my initial tests - the first is with FilmConvert film emulation applied, the second is without FilmConvert, just some basic contrast and saturation tweaks. Sorry the grade isn't very good I'm getting used to both the EOSM DNG's and FCPX's new grading tools.

My post workflow is very simple: convert .MLV files to DNG's with MlRawViewer and then drop them straight into FCPX. Do a bit of colour correction with an adjustment layer if needed, then export clip as ProRes 4444 XQ. Bring it back into FCPX and conform the 18fps to the fps of the timeline (I always use a 25p timeline and *think* this requires slowing the 18fps clip to 72% but I'm not confident my maths are accurate - it certainly looks close to normal speed to me though).

I'm not very technical so you won't find much explanation of why it's working from me. I'd appreciate contributions to what's going on here so I understand it better and other can replicate if they want to. In particular I'd like to figure out the effective sensor size I'm using, and also why there are no pink dots.

The things that excite me about it as a viable Digital Super-8 camera are:
1. The shutter speed - only Magic Lantern allows that really, and it really helps give that authentic Super-8 feel. 
2. The 12bit colour space and RAW grain makes the footage film-like and organic. 

3. The fact you can adapt C-mount lenses to the EOS-M. The lens I used for these tests is just the 15-45mm EF-M kit lens in manual focus mode. However I have a Cosmicar 6mm f/1.2 on its way to me as we speak and if I can get it to infinity focus I think I'll have a 'normal' lens (again, I need to figure out the imaging area I'm working with).

4. Shooting 4:3 and 18fps, like Super-8, allows continuous shooting.

Things I don't like:
1. Live view is not perfect but using the info button you can jump between Canon's 5x zoom to focus and ML's rather choppy live view for framing.
2. I'm not seeing horrible rolling shutter but it's no Digital Bolex so that does give it away as digital footage somewhat.

I hope some others start playing around with these settings. With the 16mm Digital Bolex discontinued and Kodak's new Super-8 camera all the rage, there's a space for a small sensor digital cinema camera to get some love.

I'm actually using a slightly newer build called "crop_rec_4k.2018Jan25.EOSM202" from magic lantern forum member dfort, available here: https://bitbucket.org/daniel_fort/magic-lantern/downloads/
However the "magiclantern-crop_rec_4k.2017Dec19.EOSM202" build which is in the experimental builds page you've linked to also works absolutely fine from what I remember - and probably wiser to use that one.
I am using the mlv_lite module yes, which means that I can't record sound unfortunately. The mlv_rec module completely fails to load on the camera when using this experimental build - I don't know if that will be fixed in future.
Once the mlv_lite module is turned on - I'm just activating "Movie crop mode", and in the raw video options I select 12-bit lossless or 10 bit lossless at max 1800x1024 resolution. The length of time you can record in 12-bit depends on how much contrast and light there is in the scene, it can vary a lot. Lowering the resolution slightly will help increase record time in 12 bit lossless. 

Here's a quick test I've done with an EOS-M using crop mode 12-bit - 1472x796. I colour corrected on Resolve, using a grading method which Juan Melara posted on another EOSHD thread (see link below the video). The music is a fragment from a track I wrote on Ableton Live:
 
Grading tutorial in the Blackmagic thread:

Cheers Mercer, your film project looks great too!
Thanks Juan, for that shot I used a schneider cinelux anamorphic with the rectilux HCDNA, which pairs nicely with the 50D. I've posted a quick video test using your grading method (this time with EOS-M footage), I put it on the magic lantern thread as it's probably more relevant there, here's the link:  
 

Thanks Juan for this great tutorial! seems to works nicely on BMPCC raw footage too.
I don't have a 5D3 but have done a quick test on some MLV files from my Canon 50D and it's looking good to me, see image below. I'll post a video if I get a chance:

@Neumann Films That was really nice! Good work. I have been waiting to see more serious anamorphic footage out of GH5. And now they released even the 10-bit option which is great. Only if it could shoot a little more slowmo than 50p. Like 100fps in anamorphic mode would be great.
You used IBIS in those handheld shots, right? How did the camera work with IBIS and anamorphic lenses. Did it make any weird shifts or corrections it shouldn't because of the anamorphic glass? Or did it just work perfectly? I assume you used IBIS setting as 35, 50 or 75 depending which lens you used.
Those SLR Magic lenses definetly focuses quite close. Or did you use some diopters with them?
