Could you clarify what “drop-out” means to be exact?

Indeed, both black 95MBs & 170MBs have been remarkable thus far @Kgncom!

He means what I described earlier, the write speed taking a nose dive during recording and not coming bac to the faster speed. Doesn't seem like you have had the problem tho otherwise you would've complained like me. I got my new 90MB SD ExPro card and will load ML to test.

There is no Sandisk Extreme Pro rated for 90 MB/s. It's either "Extreme 90 MB/s" or "Extreme Pro 95 MB/s". If it is an "Extreme 90 MB/s" maximum write speed (without overclocking) may be between 50 and 80 MByte/s. There are several different versions around and they are not always advertised correctly.

denizza you can record 60fps with h.264 codec, with RAW you can record at 46fps maximum.
You can record RAW at almost full hd 1736x976 and you can resize it to 1920x1080.
Then you can get into crop mode so its like 16mm camera field of view, in this mode you can record RAW at 2520x1054 and also 1920x1080.
Definitely buy M, its like a miracle camera.AT this price is amazing what it can do, they only downside is that you cant use it as usb camera, i mean you can if you have video grabber , hdmi works and composide video over usb works too.
Check this out and his channel, lots of info:

kit lens is 45 body around 100 used is fair , i have it since2012, not a single issue, theres no mirrormechanism , which can fail on dslrs.and fails on my 5d2
its really great compact beast.
also buy focal reducer like viltrox to get more fov and more light in the dark with lenses
im considering buying second white one

fayfray i have canvas go 64gb kingston sdxc and 128gb sandisk extreme pro microsd in adapter, red/black.
first is a bit slower, second one ia great.but both are very similar in speed.
that canvas go is cheapest i could find.i have no idea about the one you linked but find some writespeed tests for it and compare with that canvas go speed,but... come on spend 5 bucks more and get canvas go

@ 2blackbar
i was curious because they had this in stock in local store ,walmarts usually are open 24hr pre cov-19 and if your in a bind one can pick one up anytime,i bought like 15 cards before they were pny Elite-X on my 5ti i get 28 mb/s 128gb card and 33mb/s on 32gb micro sd ,thought it had some thing to do with the adapter but after trying several same results i just bought the eos m and wanted to try sd cards instead micro ,i think onn. cards are made by PNY cause the specs are almost identical to the elite -x cards and walmart stop carrying pny cards. i will try some SanDisk Extreme PRO recommended by zeek only ten bucks more thank you for your suggestion

Yeah, its better to buy tested cards not unknowns cause there are some technical specs that are hidden , cards have to be tested to see whats the real life writing speed, not "on paper" writing speed .I did a lot of digging and browsing tests before i picked mine.
I think that Sandisk is a good choice. Also my 128GB is in reality 116 GB

Storage manufacturers count GByte = 1000 MByte = 1000 x 1000 kByte = 1000 x 1000 x 1000 Byte.
Programmers count GiByte = 1024 MiByte = 1024 x 1024 KiByte = 1024 x 1024 x 1024 Byte

Translates 128 GByte = 128 000 000 000 Bytes = 119.2 GiBytes. Still some 3 GiByte missing ...

That is why a 3 TByte disk will show up with 2.72 TiByte in your computer.

If calculating recording duration you have to use 128 GByte = 122060.8 MiByte because ML will use MiByte/s.

Hi everyone!
Is there a way to record in 16:9 aspect ratio when using the 2.5k mode, i selected 16:9 and my recordings had a 2.35 aspect ratio (2520x1080).

Thanks

If the maximal size is limited, crop the width.

16:9 possible on all presets. Only select 16:9 from Movie tab menu, not from raw video menu.

Hi Masc, thanks for your suggestion, it would crop a lot. In the movie tab on ratio i left it at off and in the raw video submenu i selected 16:9 that resulted in 2520x1080 (2.35 aspect ratio), if i select 2.35 the end resolution is the same, but if i select 16:9 ratio in movie tab and 16:9 on raw video sub menu it will record in 1920x1080 but with a width crop (what you were suggesting), i was hoping i would get a wider field of view like the 2580x1080 FOV... its a crop of a zoomed crop. Will play with these settings and see what i can do. Thanks to everyone keeping Magic Lantern alive.

Thanks Danne, i was writting the reply while you posted yours. will try it your suggestion, if i want to record 16:9 on 2.5k mode i need to select 16:9 on movie tab and what in the raw sub video menu? 16:9 as well?

This is what you get - you understood correctly. There are 2 different 2.5K modes. One brings 1920x1080, the other 2192x1234 for 16:9 ratio.

Choose "2.5K 2520x1418" mode and select 16:9. That's all.

Don´t touch those settings at all. Should be at max.

Hello, I'm fairly new to the forum but I've been using Danne's build for EOSM and I've been having a lot of fun. However I've recently run into some issues (big and small) and am wondering if anyone on the forum can help.

I couldn't get the cam to record and shoot with a EFM to c mount adapter in. I had to make use of the recording delay function in the video tab, this probably has an easy fix i can't find but it was annoying to work around and was wondering what setting i need to change in ML or in camera to get that to work. I was also having issues with the SD overclock. I don't know what causes but eventually the card will refuse to record at higher bitrates, this will happen even while recording. I'll have continuous recording, everything is stable, but suddenly the write speed tanks the buffer fills up and recording stops. After that the card stays at low write Speed, I've been using a legit SanDisk Extreme pro 90MB/s 64GB and a Lexar Pro 1000x 128GB. The write speed tanking happens seemingly at random, and after that I need to clear the frame buffers, and dump the ROM, and occasionally the cards speed come back, only to invariably return to slowpoke mode. Neither of these are the big issue tho.

https://www.magiclantern.fm/forum/index.php?topic=16262.0 I ran into this problem. Flashing green LED and no boot. Camera would only boot without an SD. Regardless of what is on an SD, any SD card in Camera will make it not boot and perpetually flash the LED. I managed to save my camera by getting the camera to boot with the battery door open (i had to push in a little pin inside the battery compartment) and pushing in the SD card right after turning the camera on. This somehow avoided the flashing LED AND read the card. I used this to reinstall firmware 2.0.2 and wipe all settings and format the card again. I thought nothing of this and reinstalled ML i still had to deal with the funky SD write behaviour but everything seemed good, however after a few days it started doing the same hanging thing again, and I had to repeat the process. I am more than willing to run tests if any of the devs need some research done here as no one should have to deal with this bricked/hanging camera crap.

EDIT: So it appears that this LED hanging behaviour occurs now even when ML hasnt been installed, have to do the card thign just to get the cam to acknowledge the card. Wondering what it could be.

Looks like i have a very similar problem maybe the same here is my info:

I shoot on latest danne build and the settings are 25fps 1/50 with x3 crop in mcm rewire 1080 with 1800x1012 and it's 14 bit lossless raw. I use the kiev 16u lenses. If i expose with zebras set to 100 to avoid most clipped areas in the highlights the recording is continues most of the time. But as soon as the clipped areas increase more then a little or as soon as i am recording something that is really white the recording time gets red and it stops after 2 seconds or so. I was standing outside with f16 on the 12mm and iso 100 and couldn't record to 3 seconds. This also happened inside shooting a dark underexposed room with small windows on the other side where maybe some small areas have clipped because of the bright light outside. I couldn't even record 2 seconds. I use the Sandisk Extreme Pro and else i have no problem. Now the funny thing is after all these things happened i could expose like i want but it won't work anymore at all even if image is completely white or black. It always stops after 2 seconds and then writes the buffer to the sd card. Did i something wrong or is it just the limit of the camera? A bug? Maybe there is something happening with the datarate when some scenarios appear in the image or the camera gets unstable after the first recording? If i use the nd filter i can avoid highlights clipping better and the problem is reduced but still happening. I try to shoot documentary with it and need continues recording with 25fps (germany) 16:9 and i also need the crop mode to reduce rolling shutter. Is there anything i can do the fix the problem? :)

This may relate to the above post, but I am not sure!

Hey everyone! New here and just wanted to say thank you the Danne and everyone who takes the time to help with this awesome project.

My question (and Zeek has been very helpful via instagram) has to do with continuous recording in the "mv1080p MCM Rewire" or "HD 1080p" in the touch screen menu (i assume both are the same). I have followed all of the instructions to get continuous recording in 1080p, 14 bit lossless, 16:9, 1736x976. I get continuous recording almost all of the time but have been having a strange issue when filming outside with a lot of daylight. It seems as if something is overexposed in frame I get less data and it knocks out continuous recording.

I am using a sandisk extreme pro 64 gb/170mbs (which i bought at best buy so i think it is real) and I tested it online and it seemed to be reading and writing at about 80mbs.

Has anyone had an issue like this? If I have my image correctly framed and lit it doesn't effect but if I am using the camera on the go and accidentally over expose it effects the record quality.

This is exactly the problem that i found too. Though i must admit i fixed my fast stopping recording now because of an sd card extender that may had an issue. I can now record most of the time but still if i overexpose i may risk a stop for the recording.
