@mercer thanks! I do need to make a short film and should watch Rear Window, can't believe I haven't seen that yet! Yes I'm using Juan Melara's method on resolve, at least for clips where any highlights are blown out otherwise it's not needed. It's the easiest way to get highlight rolloff to look ok - I have it all set up on resolve so it only takes a click and minor exposure / colour balance adjustments after that.

Thanks! It will certainly be slightly similar to the 5D once the speed booster is available! At the moment, the resolutions I've mentioned above require the use of highly experimental builds that aren't even available in the experimental downloads page yet. It's a bit of a hassle getting the different modes to run, however progress is being made pretty quickly.

Here's my first quick test with mv1080 full sensor recording on the eos m (1736x1120), no crop and continuous recording in 14 bit lossless raw. I'm happy with the image quality and moire isn't too bad. I think youtube softens the image slightly, so have uploaded at 1440p which hopefully looks a bit better: @webrunner5 In crop mode at 2520x1080 or 2520x1386 the ef-m 15-45mm lens is 50-150mm full frame equivalent (3.33x crop). With a 0.71x speed booster that will be a 2.36x crop - so using an ef-s 10-18mm (modified to fit speed booster), that would result in 24-43mm full frame equivalent. The ef-m 15-45mm won't work with the speed booster. The river thames video I shot at 2224x1200, which has a crop factor of 3.75x, so the 15-45mm lens was 56-170mm equivalent there. The crop factor changes depending the resolution selected - values can be calculated here: http://rawcalculator.bitballoon.com/calculator_desktop

Have tested it and it's working fully. The preview is stretched vertically 1.6x for now - as if there were an anamorphic lens attached, but other than that it's fine. I never thought they would manage to do this! Also, seperately, here's the most extensive test I've done so far with the new crop rec 2.5k mode (max 2520x1386) on the eos m. I recorded at 2224x1200 to get usable record times of around 10 - 20 seconds per clip. It was a very warm day so the camera got pretty hot!

A lot of progress has been made on the EOS M in the last two days and it looks like they've been able to make the camera shoot in mv1080 mode using the full aps-c sensor (no crop) for the first time ever (as opposed to the mv720 mode that the camera was always stuck in). This means that the EOS M will now be as capable as the other digic 5 cameras.... so what I said before about anamorphic shooting changes completely - this will now be a great camera for anamorphic as it can record max 1736x1120 (3:2 aspect ratio) which I think uses the whole sensor height and width. Will do my first test soon - liveview preview isn't working fully yet though. Can't wait for the Viltrox speed booster to be released soon and shoot full frame raw video with this £100 camera! Here's the forum post and first footage: https://www.magiclantern.fm/forum/index.php?topic=9741.msg203530#msg203530

To update a build all you do is delete the ML folder, autoexec.bin file and ML-Setup.fir file from your SD card, and replace these deleted items with the new ML files that you've downloaded. You don't need to run any firmware update - that's only the case if you're using a new SD card which hasn't had Magic Lantern installed before. If you're planning to shoot lossless raw using the experimental 4k crop rec build, it's worth using MLV App to convert the mlv files to cdng: https://ilia3101.github.io/MLV-App/ not all of the other programs are compatible with lossless compression.

@mercer the MLV Lite module is nearly able to do all the things the regular raw module does (including sound recording), and it uses less processing power, so I think there's a discussion going on about getting rid of the regular raw module and making MLV Lite the standard one. There isn't much difference between the two modules in terms of what they're like to use. The EOS M is only worth using in crop mode, and the current resolution options means it's not great at all for anamorphic filming. The max available resolution till very recently was 2520x1080 (2.33:1 aspect ratio). At this resolution recording is continuous at 10 bit lossless, and nearly continuous at 12 bit lossless. Crop is 3.33x from full frame (which will be 2.36x crop with the upcoming speed booster). Now it's also possible to shoot up to 2520x1384 (16:9) at 24fps. However when you increase the vertical resolution beyond 1080, the lowest bitrate setting you can select is 14 bit lossless, which limits record times to about 2 seconds only! However, as I'm sure you know with Magic Lantern you can select any resolution lower than the maximum and any aspect ratio you like, to get better record times. For example, with 2224x1200 in 14 bit lossless I currently get 10-15 seconds record time. The exciting news is that the SD card overclock hack is being developed even further to increase the clock frequency from 160mhz up to the UHS-I maximum of 208mhz. When (and if) that happens then 80mb/s write speed should be possible on the EOS M and other digic 5 cameras (as opposed to 55mb/s write speed that the current hack allows). This should enable continuous recording at 2520x1384.

Thanks, glad you like it! I can't afford a new camera at the moment unfortunately - but that might change next year. The full frame look is really nice! For now I'm happy with the EOS M, I don't really need anything else. It's quite a capable camera - at 2.5k resolution I think I prefer its image quality slightly over the BMPCC I used to own. When Viltrox's speed booster comes out next month, it'll even be possible to shoot wide angle with EF lenses. The 50D was really nice in crop mode even if liveview was only in greyscale (it could do 2000x1080 in 10 or 12 bit raw continuously). Unfortunately when shooting with the full sensor it was fairly weak - looking at footage now I realise just how much moire there is, and also at higher ISOs fixed pattern noise was bad. Its biggest issue was battery life which seemed even shorter than on the BMPCC - the EOS M battery goes on forever in comparison!

@hmcindie nice colours and very intense! well done! I recently sold my Canon 50D as I wasn't using it much after I bought my EOS M. Here's the last video I did with it, using a Tamron 18-200mm II lens, which isn't particularly great:

@tupp very interesting videos, thanks for sharing! If it were simply possible to swap out the UHS-I SD card interface inside the EOS M for a UHS-II one, that would make higher resolution recording feasible. But I imagine the amount of coding required to make it work might make it very difficult. In any case I doubt you'd be able to sell and make any money from a hardware hack like this - unless you get permission from Canon! I spoke to a Canon rep at the media production show in London recently where they were showing off their cinema EOS cameras, and he was aware of the EOS M 2.5k hack and seemed totally positive about it even saying he'd like to try it himself. I showed him the hack in operation. He also said he hoped that magic lantern would be available for the M50 one day!

It would be amazing to get the dvx100 hack working. It looks like they were connecting a laptop to the camera and running it from there? I just wouldn't have a clue how to do it! Here's 4k filming with the EOS M at 9fps (4096x2552), it's only possible to shoot 5 frames at a time though. At this resolution, the crop factor becomes 2x (micro four thirds). I don't think it'll ever be feasible to get this to work at 24fps. Even with the extended SD overclock hack writing at 80mb/s, it would only be possible to record a second or two, the data rate is just too high. Don't know if it would be possible to hack this camera with an external recorder and increase the write speed that way, but that's just too much work!

Thanks! Hope I can do a tutorial someday. Right now the SD overclock hack is simple enough to use, at least compared to the next phase of development that is being carried out to increase the resolution beyond 2520x1080, which is an extremely complex process. We're hoping it will be possible to overclock the SD card interface even further at some point. With the current overclock hack the write interface runs at 160 mhz (up from 100 mhz natively used by Canon). If the developers find a way of getting the frequency up to 208 mhz (the max UHS-I cards can achieve), then the camera's write speed could increase up to 80mb/s apparently (as opposed to 55mb/s with the current hack). That would make 2520x1320 recording feasible, possibly even 3k recording. In fact I just saw that a new build has been posted enabling 4k recording for the EOS M and 100D. Will test tomorrow but doubt it'll be possible to record longer than a few frames! Here's another really quick test recording 2520x1320 and 2336x1314: @PannySVHS that looks very interesting and would be great if someone could look into reviving that hack. The colours look amazing, must be thanks to that CCD sensor! Unfortunately I have no coding knowledge so wouldn't know how to help. Magic Lantern development on the EOS M has progressed quickly since this thread started and now in crop mode it's become a 16mm camera (thanks to an increase in resolution capabilities) - so the title of this thread is slightly out of date. Maybe I should start a new thread! Of course it's still possible to shoot super 8 at 720p without using any of the experimental builds.

The 700D, 100D and EOS M are now able to shoot around 2520x1320 in crop mode (previously 1080 was the max vertical resolution). 3k is also possible although liveview doesn't really work at that resolution. Record times are very short as it's only possible to shoot in 14 bit lossless for now. Here's my first successful test with the EOS M recording at 2520x1320 and 2336x1314:

Looks like the magic lantern developers are getting close to 3k raw video recording on the 100D and 700D. I'll hopefully be able to start investigating the EOS M too as that's a similar camera. One issue at the moment is that 10 and 12 bit lossless are unsupported at this resolution, so record times are very short, and it's all extremely experimental at the moment. Here's the link to the 100D thread re: this topic: https://www.magiclantern.fm/forum/index.php?topic=16040.msg202627#msg202627

Here's some more footage shooting 2.5k raw video:

@ntblowz cool thanks for posting that link. I had written to viltrox last month and they told me the same. It's great they've finally done the public announcement! Can't wait to use it on the original eos m which now shoots 2.5k raw video.

@tupp the lossless bitrate menu settings seem to keep changing with each build I install - sometimes I see 10 bit lossless in the menu, and other times 11 bit. I don't know why but in any case I've never been able to see a difference. Danne's newest test builds which bypass the overclock tests are meant for 95mb/s Sandisk Extreme Pro cards which is what most people seem to be using. It's possible it works on other brand cards but I don't know. Thanks for talking to the card manufacturers, sounds like a great idea! What would be nice is if they could increase the write speeds for UHS-I SD cards (of course there's UHS-II, but that's no good on an EOS camera) - I'll write to Sandisk. I wonder if it's the card that's being overclocked or the camera's internal card read/write interface? Yes in that video there was just the open sky in the background which was blown out. But using Juan Melara's cdng grading technique the highlight rolloff looks more pleasant (see here: http://juanmelara.com.au/blog/a-better-way-to-grade-ursa-mini-cinemadngs ) My card already came formatted to exfat since it's 64gb size (I think the 32gb ones are fat32). When I put ML in this card I just copied pasted the files on there after formatting the card in camera I think, didn't do anything special. You can format the card to fat32 but I haven't seen any improvements in max write speeds when doing so.

@tupp thanks for posting that video - All-I frames video looks like a great option when recording with the full sensor! As for 1800x1030 resolution (without the sd card hack), with 12 bit lossless you can record for a long time if there's not too much contrast or highlights in a frame. 10 bit lossless is continuous There's some slow progress being made with the sd card hack, it's now possible to use it without having to run tests (which took around 3 minutes every time the camera was turned on), so it's quick to start up now. However that build only works with certain fast cards, and it's still not safe to use. If you try that build with an unsupported card, I don't know what would happen to it. Below is my latest test, this time with people! I'm using a Sandisk extreme pro 95mb/s 64gb card I'm still getting a max of 55mb/s write speed. At 2520x1080 resolution in 12 bit lossless, recording runs for quite a while unless there's a lot of highlights and contrast in a frame. 10 bit lossless is usually completely continuous. I shot this when it was 26 degrees celcius outside, but the camera worked - it didn't go above 42 degrees C. Also I've now bought a Canon efs 10-18mm lens. Waiting to get a viltrox 0.71x speedbooster when it's released. That speedbooster combined with this lens at 2.5k resolution in crop mode will result in a field of view of 24mm (35mm full frame equivalent). That's wide enough for me and will make crop mode totally usable.... and that lens has IS which works nicely.

I wrote to Metabones and Viltrox about this - Metabones said they have an ef-m speedbooster in their plans but couldn't discuss any further details. Viltrox said they're planning to release one in a few months.

@TwoScoops That's the write speed and resolution the 5D4 could achieve if it had magic lantern enabled, but it doesn't yet. Could be years before we see magic lantern on that camera.

I think someone posted a build with the mlv_lite module able to record sound a while back even before the hack was available. It's in the magic lantern forum somewhere. I'm sure it should be possible.

Hard to say, depends on whether someone is willing to put in time and effort to enable 1080p non crop on the eosm. If you're interested and want to help out with the development, there's a discussion about this on the magic lantern forum: https://www.magiclantern.fm/forum/index.php?topic=16608.0 None of the digic 5 cameras can shoot 1920x1080 in non crop mode, I think only the 5D mk III can do that. Here's the magic lantern raw calculator which gives you info on the different camera resolutions: http://rawcalculator.bitballoon.com/calculator_desktop

The hack doesn't change the usability of the camera - you can use it the same way as without the hack. You can shoot without crop mode with the hack enabled, although it's probably not worth it? You can shoot all bitrates in raw with sound, but not with lossless raw since that uses the mlv_lite module. However I think someone managed to enable sound recording with the mlv_lite module - worth checking on the magic lantern forum. In non crop mode the EOS M can only record up to 720p raw (with a lot of aliasing and moire). Using 3x3 pixel binning mode (also non crop) it's still 720p max but at least there's slightly less moire. Regular h.264 is 1080p in non crop mode (with or without the bitrate hack). There's a discussion about that camera here: https://www.eoshd.com/comments/topic/26577-is-the-eos-m-the-digital-super-8-camera/ I posted a video I've done with the EOS M + SD card overclocking on that thread, but reposting it here since that hack is relevant to a number of other Canon DSLRs. Works the same way on the 100D, 700D, 650D and others:

I've uploaded another video with the SD card hack: @tupp It takes about 3 or 4 minutes to do the two tests before the sd overclock is ready to use, and then the camera runs as normal. You should be able to shoot 1920x1080 in 5x zoom mode without overclocking in 10 bit lossless - you won't get much record time but it's feasible. I can already get nearly continuous shooting in 1800x1030 12 bit lossless movie crop mode. I did notice it isn't possible to shoot video without the "release shutter without lens" enabled, don't know if it would be possible to get around that with Magic Lantern. Also, unsure if I mentioned that Viltrox are planning to do a 0.71x focal reducer for EF-M mount - they told me it should be out in the summer. I don't have a bmpcc speedbooster any longer so this should be a cheaper alternative, with the advantage of electronic contacts for EF lenses.

Here is my first test filming 2520x1080, 12 bit lossless on the EOS M with the sd card hack, this shot is 2 minutes long using the stock zoom lens and a sandisk extreme pro card. Processed via MLV App and Resolve: Currently you need to perform an overclocking test and then a benchmark test for your SD card after each time the camera is turned off, so it's a bit cumbersome. Here's a still - a cdng processed through photoshop, different colour temperature than in the video:
