This is the card I am using.

I just can not record 4k resolution without lower half pink frame after 1 min, and it starts to skip frames after 40 seconds or so. I am using 5k anamorphic mode and I tweak the settings to 16:9 in croprec and 2.35:1 in 5k anamorphic settings, then max the resolution which equals to 3500x1500 when strectched. I was able to record 4464x1900 resolution (when strecthed) but now I can not achieve it again and I do not remember which mode I have used to record it.

Which mode is best for recording 4k ?

I'm not sure if using a microSD, especially one of that speed, will be able handle what you're trying to throw at it, especially depending on what other settings you have set within ML.  I think most people use the ExtremePro 95MBs cards, wheras I think your card is 30MBs.

Can you send me samples of what you shoot ?

This card can record 4k in EOS m50, though I know it is 8 bit. I do not understand why it would not record 40 mb/s data in ML eos m.

HUGE difference in 8bit 4k and RAW.  A completely different beast, it's pretty much the purpose of ML.

I used all Danne builds from February until March 24th. I was able to continuously record the build on March 24th, shooting the two sd luas and 2.35 cinemas, in 4.5k. Proved that if I cast two or three recordings the pink frames occur but then in the next recording stabilizes and stops making them. This is my card

Seems that card will be able to do write speed of 60mb/s while smaller than 64gb will do max 40mb/s:
https://www.cameramemoryspeed.com/reviews/sd-cards/sandisk-extreme-90mbs-64gb-sdhc-memory-card/

To be sure one needs to benchmark the card. There are modules for this created by a1ex. Simply use another build and run the benchmark tests. Search on the forum how to do the tests correctly.
One way to test is by filming. If youre card reaches around 53 to 55 mb/s while recording 5k anamorphic 2.35:1 it´s probably ok to use. If not, reconsider getting a faster card. The only card I use that I know reliably works is the extreme pro version but others might find other brands or cards.

The card I am using is that one. It says it easily reached 60 mb/s and even exceeds it. I will benchmark the card while shooting. I want to shoot exported 4464x1900 resolution, I have a clip like that but it is only 3 seconds. I do not remember if I stopped the recording or not, but I do not remember the settings I recorded for that clip so I dont have an idea how to do it again. Does auto stop recordings save to card ? I mean, when it becomes red it only records for 1 sec or so and automagically stops recording.

There´s two ways to find out what is pratical to use when it comes to recording and what works or not

1 - Start reading from here and check all posts:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

2 - Short answer. Install magic lantern and run the cinema 2:35.1 lua script. By doing this you will get right into this preset:
5K anamorphic but it will run in 2.35:1 ratio and continuous. The new ratio will be:
1488x1900 Which when imported into Mlv App will upscale to magical, tada:

4464x1920

The other highres presets simply won´t work with full fps(24fps or 25fps that is) but with reduced fps.
Please. Before posting further do go through all posts starting from the provided link above.

hi everyone , today tasted the latest build and notice some strange dots line in bottom of the frame in 2.35 : 1 45\48 fps mode 10 bit . It's very simmilar  to focus pixel dots.

Maybe it´s focus dots then? Tested chroma smooth 3x3? Tested dfort pixel map files and put them into Mlv App?

Yes, those are focus pixels.

When the pixels are too close to the edges of the image the interpolation algorithm can't handle it because there are not enough pixels to sample. Adding more chroma smoothing or the "median filter" in dcraw won't help. One way around this is to crop out a few pixels in post. You need to resize anyway if you are working on a standard HD or UHD project. Another way around this is to try a larger image size. Yes, larger because the focus pixels at the edges of the sensor usually don't light up.

Here is an image of the full frame buffer showing the out of bounds area in dark grey and the focus pixels on the active area.

Guys is it possible to hide only histogram when recording raw and making it appear autimatically when not recording ? That would be super useful.
Or display only camera passepartout when recording raw for chosen aspect ratio to save as much cpu cycles as possible without disabling overlays completely.

I've just finished smoking this thread starting from page 70. First of all I would like to thank Danne, dfort and many others who helped testing releases and iron out the bugs. It is absolutely incredible what you guys have achieved here. I used to be a Sony guy with 3 Sony bodies and only one Canon (6D), but because of ML and mainly the video raw capabilities that have opened up to us recently I now have 5 Canon bodies (withing a month I purchased a 5Dm3 and 3 x EOS M). Raw video is so addictive.

Now, while I've been reading the thread and came across many 'bug' reports, I felt that possibly?? some/many of them could be related to the cards people are using (which is possibly the reason why they couldn't be reproduced by Danne). For raw filming I personally use Sandisk Extreme Pro cards exclusively and have come across very few glitches with ML on my 6D or EOS M and they have been the same - I routinely get one or two corrupted frames at the very beginning of my takes  with the rest of the footage being fine. Since we 'overclock' the interface, making it write faster than Canon wanted us to, maybe it's crucial to use the highest quality cards.

I only have limited experience with EOS M - so far I've been using the old Nightly.2018Aug07.EOSM202_mv1080p build because it gave me a quick access to full sensor 1736x976 mode which I used for filming two music clips last weekend and a few test takes in the last two weeks. I wanted to read the thread and get up to speed with all the new development that took place after July last year before installing the latest build, which is what I'm going to do now and dive into all the new stuff.

I hope to be useful to the community that has given me so much and give back something. Would there be any interest if I shared my experience with different raw processing workflows?

baris3 - if all you want is trouble free 4K footage and don't care/don't understand/don't need RAW and just want higher resolution videos - I would suggest you stick with M50 and 4K video it can produce. RAW video, especially using ML is much more involved, especially if you want to push it to extract every bit of detail/color information out of it. Do you shoot raw photos or jpgs? If you shoot raw and understand what advantages it gives then you can understand the advantages of raw video - it's the same. However if you take jpg pictures and are happy with them, raw post processing workflow will be overwhelming for you. I can record only about 27 minutes of 1736x976 14bit raw onto my 64Gb card (are you ready for HUGE files?) If you increase these dimensions by a factor of two (which is close to what you will get when approaching 4K anamorphic), that's 4 times more information, so a 64Gb card would be able to hold only about 7min of recording (a bit more if you record 10bit). Do you want/need that?

Found a bug with dots appearing on footage in most recent build:

It happens when i use aspect ratio 2.35:1 from croprec menu or 16:9 and if i turn aspect ratio off then dots disappear but then i have serious problem with shutter speeds and cant get lower than 70 cause it loops back to 4000.
mv1080p 1736x1158 mode.not see it on rewire mode.

YEah i have dfort pixel map files in folder with mlvapp but it doesnt help when i press buttons in fix focus dots.OR do i need to do something more?
Its resolution 1736x738 and i dont see this resolution in focus maps scripts folder.Does anyone has that ? How to generate it ?

Yeah i did, im looking for some info how to do focus pixels map myself so i dont have to bother him.
Found something here  https://www.magiclantern.fm/forum/index.php?topic=16054.msg207474#msg207474
and posting for myself later mlvdump with gui to work faster https://www.magiclantern.fm/forum/index.php?topic=19460.0
aaand dcraw gui http://meguidcraw.blogspot.com/2009/07/descarga-download.html
Well, it appears that 1808x1108 focus pixel map is for my particular file but it still doesnt work, is there any way to fix this in cam? I can clearly see focus dots disappear for hal second when i exit ML menu so it(disabling focus pixels) is something thats already being done by ML with menu exit function.Why not making it a feature to turn on/off for manual focus lenses?

I noticed when using MCM Rewire the HDMI 480 (lo-res) output stopped functioning (I use a Feelworld 4k monitor).
HDMI 1080 works just fine, so no problem there, but you loose Magic Zoom and that's a pitty I think.
Focusing is much harder now. Is there a fix?

Danne is there any way that i could get different pattern of focus pixels so MLVapp would be able to remove them ?
The ones i currently have are having some issues:
https://www.magiclantern.fm/forum/index.php?topic=16054.new#new
Id rather change something in camera in the future so it would be possible to remove my focus pixels, i also by accident got different patern of focus pixels in ML, it was something like this but i cant turn it on again:

I would like to change something in camera so dfort focus pixels map would work on my future cinemascope 1736x738 footage.I think its smarter this way instead of having every situation covered , just make camera show focus pixels in a pattern that is known to be removable.

It´s not clear to me what exact setting was used. Could you share me your whole SETTINGS folder inside ML folder?

Was it mcm rewired set to 2.35:1?
Only reduced to 12bit from Crop mode sub menu or any other changes?
Need to know exact set up to reproduce so sending the SETTINGS folder should be best.

no it was not rewired it was the one above it, 1736x1158 under Q settings were 12 bit and 2.35:1 ratio.
raw video settings were
res 1736x738
aspect 2.35:1
14 bit lossless
preview frozen lv
In canon menu AF method - flexizoneAF⟁
My settings folder
https://drive.google.com/open?id=1jfQCNMKw0hsiG6r4JPhvAQd5bTbbWK0d
What focus pixel pattern do You have on your canon M in the same mode ? Can you record in cinemascope 1736x738 and then remove focus dots in MLVapp ? If yes then could you share your settings folder so i could adapt my cam? Maybe theres something wrong here in my cam because this format is quite popular.

Thanks.
Frozen liveview? Why using that?
Anyway. Try using the mcm rewired mode and set it to 2.35:1 and 12 bit in Crop mode sub menu. Should work better with real time and perfectly aligned liveview.

Because i had pink frames when using framing preview and now i have 0 pink frames if i use this black/white preview.Also its mostly because of histogram.This mode works ok with histogram on.framing mode gives pink frames with histogram on, unless there would be an option to disable histogram during recording , i mean histogram is not on screen when recording but disabling it and switching to blackwhite view made pink frames thing of the past for me, i dont really need anything besides properly cropped image on screen but using kill global draw removes cropmarks for cinemascope, i would like them on and everything else gone when im in framing mode recording .
Ill do as you say and will try to remove pixels again in mlvapp.

i don't know if relevant but it was mentioned that mcm rewire mode doesn't work with bit options in crop mode sub menu. must be set in raw video sub menu if needed.
