I'll have a look @alex. Thanks for links.
And yeah, good for stills and maybe even h264 recording(pushing fps override etc)

Today retested the last build and unfortunally get corrupted frames in 48fps mode , not consistant but somwhere after 5 - 10  seconds after starting video/ in 16:9 and 2.35:1 aspect ratios and 12 or 10 bit.  Global Dwar off .

MCM mode works perfectly in all aspect ratios and bit depth

Hi, I´m new to this forum and this buid of Magic Lantern and i love it!
But after the first clip my screen gets really weird, wrong aspect ratio and if I try to record some more movie I get an error and I have to re install the magic lantern before i can record some more.
Anyone else have this problem or mayby a fix for it?

Best regards.

When using last version from 24th of March get always a message at the start:

Please enable sd_uhs module.

But this module is enabled. Somehow ML doesn't recognize it. Is somebody else getting this error or it's just me ?

Reverted back to the 14th of March version and there everything is OK. sd_uhs is recognized and started with the start of the camera.

Another small issue is with live view and custom ratios.

Using 2.5K 2520 1418 mode from crop_mode menu

With standard ratio of 2.35:1 set by the script in crop_mode menu, live view works correctly. Image is refreshed at slower rates and turns black and white when recording but presents a correct view of what will be recorder. This in my understanding and experience is how live view works in crop mode.

But my preferred ratio for video is 2:1. And in order to get it follow Danne's instructions in previous post:
   - 2.35:1 ratio in crop_mode is turned off
   - change the ratio to 2:1 and resolution 2400x1200 in RAW_video menu. 2520x1250 doesn't give me enough seconds of recording so I lower the resolution a bit

But at this point live view doesn't work as it was working when 2.35:1 ratio was set. It turns to x5 crop. So I see only a portion of the recorded image. Only when half pressing the shutter, then see the picture as it will be recorded - at lower fps and as it was when ratio is 2.35:1.

So my question is: Is this behavior by design ? And could it be made to work consistently across all ratios ?

Please enable sd_uhs module.
Seems to me you are still using the lua overclocking script. It´s not needed anymore. Simply enable sd_uhs module and it will patch when starting camera. If notplease send me your whole SETTINGS folder from inside ML folder on card root.

Ratio issue. Is your preview mode set to framing?

entering canon menu might interfere with auto preview mode. in raw video menu set crop rec preview to "off" and preview to "framing".

Thank you Danne and optical-work for the help! Setting preview to 'framing' indeed made live view work as wanted and expected.
Was not aware that lua script was not needed anymore. Formatted the card, installed ML latest version and message about sd_uhs is gone. Maybe there is an easier way to stop lua script but this one works too :)

Many thanks to Danne and others for the great work that made EOS M such a nice raw video camera !

Hey guys, thank you for all your effort :)
I am following all the discussions here since half a year and the results so far have been great!

1) I am wondering how can i use dfort pixel maps for MLVApp 1.6. I recorded a video in 1280x1920 with 5k anamorphic (which will result in 3840x1920) and i am seeing focus pixels, how can i get rid of it. i know there are some focus pixel maps from dfort. i downloaded his whole repository and put my mlvapp in the directory of the *.fpm files. but i think there is none for this resolution. so what to do ?

2) i was wondering what is the difference in between the mcm mode and the mv1080 mode from before. somehow i forgot it and there is too much in the forum to find the explanation back again. Thanks ;)

1)... i downloaded his whole repository and put my mlvapp in the directory of the *.fpm files. ...
Should work. Doesn't picture in viewer change when toggling the focus pixel buttons? Please send a short MLV...

2) i was wondering what is the difference in between the mcm mode and the mv1080 mode from before. somehow i forgot it and there is too much in the forum to find the explanation back again.
Main difference for the user is:
-mv1080: slow preview
-mv1080 mcm: real time preview

Hey guys is it possible to record mov files cropped  and save some cpu cycles?
I noticed i have less rolling shutter when im recording raw 2.35:1 compared to recroding 16:9 even in mov h264.
That pre recording crop for sure lets camera record faster when i use 2.35:1 so it doesnt have to sweat as much as when recording 16:9, so is it possible to record actual 2.35:1 to h264 mov files ? That improves rolling shutter and would be worthy from what i see.
What do You guys think ?

I think h.264 looks like crap so why bother?

If that is possible it would be a nice addition to the magic lantern features, i think everyone in the past has cropped 16:9 mp4 video to 2:35 aspect ratio, if magic lantern could do 2:35 native mp4, the bitrate distribution/video quality would be better on 2:35 video since no bitrate is wasted on "future" cropped areas, only used on actual video.

I don't think it works this way. Do you have some data backing up your opinion?

Hi Walter.

1 situation - using EOS M and record a 16:9 (1920x1080) mp4 and crop it to 2:35 for whatever/cinematic reason.
2 situation - using EOS M to record a true 2:35 (1920x817) mp4 video

since the actual picture dimensions of a 2:35 video is smaller than a 16:9 video the video bitrate efficiency would be better and in theory should have better quality since no bitrate is wasted, lets say that the eosm records at 30mb/s using h264, the quality on the true 2:35 would be better than a 16:9 cropped to 2:35 using the same bitrate.

Since 2:35 is using 263 less height pixels the bitrate used on those (top and bottom)  in situation 1 IS wasted if you are cropping.

Im not a pro but i think i understand a little of the basics, sorry for any confusion...lets imagine that the EOS M has a 16:9 and 2:35 modes using h264, both use 30mb/s for video bitrate, if we crop the 16:9 to 2:35 and compare its quality to the 2:35 version we could see that the 2:35 has better quality, better bitrate efficiency.

but i could be completely wrong...this is my opinion based on what i learned reading several video forums over the years.

Good questions...
- i cant preview mlv in camera smoothly or i dont know how im using raw since a couple of days.
- filesize , raw is about 3 times , sometimes i dont need so much freedom to color correct as much i try to get good image in camera so im recording 10bit losless.
- mostly i would like better rolling shutter and its definitely better when recording raw.
I actually record raw but im curious is it possible to do the same thing with canon's h.264 mov files and get rolling shutter improvement like when filming raw.
If not possible then fine.
Anyone knows whats good enough card to get 1080p in raw recording on M , 14 bit with continuous, so i dont have to worry about anything?
Not the best card, just good enough.

I'm using a Kingston 64Gb (Canvas go!)
https://www.amazon.com/Kingston-Canvas-32GB-Memory-SDG/dp/B079SQBCWF?th=1

continuous recording at 1736x976 14bit, fills up the card in 30minutes.

Thanks ! After correcting a few shots i did today with RAW i just realized, im not coming back to h.264, it just doesnt make sense and ill just get better SD card.
With some shots i could not believe RAW is that good, i thought i had another shot underexposed to preserve highlights but its almost like magic, the amount of highlights you can restore with raw is like a miracle to me.
Sorry for dumb question with h.264... now it feels almost insulting to bring h.264 suggestions in here.I love RAW.

Hey, i'm testing out the Raw recording for the eosm, i have some newbie questions:

1 - Does the MLV file comes with the Picture Style grading?

2 - Should the MLV footage be darker than the live view output?
I can't ever recover the exposure when i record it at 10bit color range.

Thanks in advance

I don't want this to come across as advertising, because this ain't that. lol
but if anybody has any "noob or newbie" questions, the facebook group I started may be a better place to ask "getting started" type questions instead of the development thread.  There are also several videos people have shared of what they've shot with the M and I'm sure there are more on the way.  Any and all are welcome :) if not allowed, delete.

Hello,

I am new to the magic lantern and I purchased my M50 2 months ago, so I decided to give ML a try on my EOS M. My main purpose is record 4k video (not raw).

I have downloaded the nigthly build first and there was no 4k record option.

Then I have found your latest release on this thread with 2.35:1 script and downloaded it, installed it on camera.

I have set the resolution to 4k, 2.5k etc with 2.35:1 ratio and,

I recorded short videos and when I look them up on the computer, the resolution is 1920x1088.

What am I doing wrong ? I just want to record normal 4k video with 2.35:1, is it possible ? Or do I need to shoot raw and enable the RAW modules ?

Can you help me ?


Thanks.

EDIT: I have loaded the RAW recording module. But when I select 4k it says it does not support more than 1800 resolution and when I try to record it that way recording stops, liveview brokes. *turns pink. Also the liveview occasionally turns pink and can be only fixed by restarting the camera. Is it because I press the half shutter button to go back into live view mode ? How to go back to liveview mode from ML menu without pressing the half shutter ?

I do not even need raw 4k 2.5k normal video should be fine but I can not record.

I would like to take a zoom c mount 12.5 75 and ask you if with resolution 4.5k it will produce vignettes. I can't figure out which size of sensor it uses. Thank you

baris3 you need at least 45mb write speed card, usually it comes with 90mb read speed but not always, i have one it was recommended to me a few posts before yours, works great and i can record at 2520x1418 as maximum size.
I had 10mb speed sdhc card class10 and i could record 11bit lossless  raw in cinemascope 2.35:1 for 20 seconds which is quite good considering 10mb speed.It was 1768xsomething
You cant record above 1080p without using raw, if you want to record something else than canon 1080p files you have to use raw.
marcelo with some c lenses you get soft corners in 3x3 crop mode, there are some tests on youtubes with c mount raw which look great but jey probably use 5x5 crop
In worst case scenario you will sell the camera if you wont like it.
