Im using f1.4 tamron 4-12mm and i ripped plastic cover to expose aperture mechanism and control it.Im planning to get something from 12 to 80mm maybe more tele as well.
Crop mode on M is exact fit for 1/2" lenses, 2/3" and super 16mm film camera lenses
--
Adjusted 2.5k again, i had thin lines probably because skipping top and bottom was not accurate.
Code: [Select]
case CROP_PRESET_2K_EOSM:
            /* set ratio preset */
            if (ratios == 0x1)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 8;
                skip_bottom     = 38;
            }
            if (ratios == 0x2)
            {
                skip_left       = 36;
                skip_right      = 36;
                skip_top        = 0;
                skip_bottom     = 28;
            }
            if (ratios == 0x3)
            {
                skip_left       = 197;
                skip_right      = 197;
                skip_top        = 8;
                skip_bottom     = 204;
            }
            break;


Code: [Select]
            case CROP_PRESET_2K_EOSM:
  cmos_new[5] = 0x2c0;             /* vertical (first|last) */
              cmos_new[7] = 0x2a8;    /* pink highlights without this */
                break;
               
Well , looks like lines are there from pressing left arrow on wheel and coming back to framing preview.They disappear slowly and are gone after about 10 seconds.

Can someone please help me with where I need to put this code? I also would like to use these same lenses and have trouble because of uneven vignette.  :)

This code is part of a module named crop_rec.c
Assuming that you use an EOS M, you'd need to compile Danne's build.
If you are on Windows:
Download Cygwin at https://www.cygwin.com/setup-x86_64.exe in "%UserProfile%"\Downloads"

Open a command prompt (press Windows+R, type cmd) and get Cygwin installed with the required packages:
Code: [Select]
cd %UserProfile%"\Downloads
setup-x86_64.exe -s ftp://cygwin.uib.no/pub/cygwin/ -q -P mingw64-i686-gcc-core,gcc-core,make,mercurial,python37-docutils,perl,wget,unzip,zip,diffutils

Open the Cygwin Terminal from the start menu.
Download the GNU Arm Embedded Toolchain and extract it in the right folder:
Code: [Select]
cd && wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/9-2019q4/RC2.1/gcc-arm-none-eabi-9-2019-q4-major-win32.zip.bz2
unzip -q ~/gcc-arm-none-eabi-9-2019-q4-major-win32.zip.bz2 -d gcc-arm-none-eabi-9-2019-q4-major-win32
rm ~/gcc-arm-none-eabi-9-2019-q4-major-win32.zip.bz2

Clone the repository and the right branch (hg identify -b should show crop_rec_4k_mlv_snd_raw_only):
Code: [Select]
cd && hg clone https://bitbucket.org/Dannephoto/magic-lantern_jip-hop/src/unified/
mv ~/unified ~/magic-lantern_dannephoto
cd ~/magic-lantern_dannephoto && hg up crop_rec_4k_mlv_snd_raw_only
hg identify -b

Modify what you want to in C:\cygwin\home\<username>\magic-lantern_dannephoto.
In your case crop_rec.c (replace <username> by yours).

Get to the right platform (EOS M here), cleanup, compile, move zip in C:\cygwin\home\<username>, cleanup again:
Code: [Select]
cd ~/magic-lantern_dannephoto/platform/EOSM.202
make clean
make -j4 zip
mv magiclantern-Nightly*.zip ~/
make clean
cd && ls

Copy the content of C:\cygwin\home\<username>\magiclantern-Nightly.YMD.EOSM202.zip to your SD card and you're set (a reinstallation might be necessary depending on your modifications).

Hello, I was wondering if the EOS M could shoot continuous at 1080p at a 4x3(1436 x 1080) aspect ratio? I am planning on shooting a short film this summer and want to get better quality video than what my Fuji xt1 can get. I have a Kowa 2x anamorphic that I plan on using so I'd like to shoot at 4x3 so that I get a 2.4 aspect ratio after the stretch. My main concern is that the EOS M has a limited record time at anything deeper than 10 bit at that ratio but I can not find specific information about it and I would like to know for curtain before pulling the trigger on buying one. Thank you.

I have the same equipments. I'm recently shooting continuous at 1392x1158. With 2x stretch, the resolution changes 2784x1158 (2.40:1 aspect ratio). Of course, you can also shoot continuous 1536x1158 if you want (1:33 a/r to 2.66:1 a/r).

I just tested 1440x1080 with the mv1080 profile on a bright scene with the sky in frame.
It goes past 52 MB/s at times when overexposed at 14 bits so it's not continuous
I get 45 MB/s overexposed at 12 bits and exposed for the sky at 14 bits, around 36 MB/s exposed for the sky at 12 bits.
12 bits should be safe but I've only tested recording a minute.

I can test 2,5k real quick if you don't mind the crop.
edit: 2,5 k, same resolution and bit depth so I get more or less the same results .

You can just back the resolution down a bit if you want continuous, I doubt you could notice the difference, especially using anamorphic lenses (I can't). If you want to get it back up to 1080 just upscale on export from MLVapp.

I'm on a Mac... I gave it all a go but couldn't get it to work  :( .

@2blackbar - would you be willing to share your build with me? Would definitely be a huge help, I've got the same lens as you.

Hello - a little help as I have looked into using the focus stack tool on my M - but in my absence from using ML actively for a while I am not sure the build I have support the focus tools at all.

I have build Nightly.2017May28.EOSM202.

And I can not find any of the focus tools in the menus.

I know I probably am clueless - but....help?

I now see that I approached this issue earlier as well without ny resolution - sorry if this repeating myself, but the issues with using the M lenses are they still there? And what if I use an "ef" lens will I then have access to the tools on my M? If so which build should I look for?

Thankful and happy ML user (apart from my lack of m-focus-tool).

(The focus move (and and trigger without focusing) work with Canons Camera connect app on M3 with same lens - so I thought the lens┬┤ability was there generically....)

Im using mostly 2.5k mode with this lens and set it to  1920x1080p by dropping down resolution from 2520xsomethingdontermember.
You can finetune framing by toching on those triangles on sides, your framing will moev a bit.
Sometimes after you finish recording , framing is moved , you can reset it to be fine again by refreshing ml view, by pressing info button a couple of times to come back to liveview.

Hi, is anyone here who uses FRSP (full res silent picture) feature on a regular basis or at least played a bit with it?

1, What is the range of the usable shutter speeds when it comes to FRSP on the EOS M?
2, Can you use FRSP with exposure bracketing? Or focus stacking?
3, Can you successfully integrate FRSP into Lua scripts? For example: 1st command: take FRSP; 2nd command: change exposure; 3rd command: take FRSP and so on.

I am thinking about buying a used EOS M10 (found one for a pretty good price) but I want to use primarly the pure electronic shutter (FRSP) because I will be taking huge amount of photos (reference images and photogrammetry).

The second option is to switch to a micro 4/3 system that officially supports pure electronic shutter (Panasonic, Olympus, Fuji, ...). But that would be more expensive as I already own some Canon gear and accessories. Also some native lenses (e.g. Fuji) are quite pricey and hard to get as used. Also the size of the sensor is smaller.
But the unique feature of the EOS M + Magic Lantern combo would definitively be the ability to run custom scripts (providing the FRSP works in scripts). Hardly any other script-able cameras on the market.

Just to be clear I am not completely new to FRSP, I know some of its limitations, I own EOS 550D and experiment with it but unfortunately the 550D has extremely narrow range of shutter speeds you can use for FRSP (0.5 to 0.8 sec). I need a camera with bigger range. I don't mind using ND or polarising filter for bright scenes.


Thank you!

Lua can be used to modify shutter, iso, other settings. If frsp enabled shouldn't make no difference.
Longer shutter times than with 550d. Don't think so but not sure here. I tend to use lua scripts and run 5k anamorphic flv preset instead for easier workflows straight in mlv app.
If I want long shutter times I would set cam to cr2 photo mode and run some lua or ml bracketing feature with or without a customized lua script. I never heard of a worn out eos m shutter ever.
The lua function really is a winner. Not any cam I know of outside ml has this feature available or anything close to it.

The reason why I avoid using FRSP is that this mode does not allow proper aperture control on some of my best lenses and I cannot stop them down enough for reasonable depth of field.  I prefer the 5k anamorphic setting in the Movie mode instead.  The image quality degradation compared to FRSP is negligible and not perceptible unless you pixel peep at 100%.  Even then, you will barely see a difference in image quality.  You can set almost any shutter speed starting from 0,4 fps and have full aperture control and very useful focusing aid tools.  Danne also implemented two very useful averaging options which do a great job with noise reduction, in case your photos need to be taken in low-light conditions.  For timelapses, you have very smooth transitions and zero dead time from frame to frame which provides very smooth footage.  Finally, 5k anamorphic provides enough vertical resolution to be used with Dual ISO too.  This will give you up to 3 stops more dynamic range while still retaining high image quality.  Personally, I prefer Dual ISO to stacking bracketed photos since it provides a more natural result out of the box and saves me a lot of HDR tweaking in post - I am not good at that.  And as Danne said, MLVApp can process your footage/photos directly and this will save you a lot of time.

Finally, an used EOS-M is so cheap now that you cannot go wrong with it.  If you buy also a Viltrox x0,71 Speedbooster, you will enjoy a further boost in wide angle performance with the EF lenses you have.  A also recommend a LCD viewfinder for working at bright light, otherwise you barely see the screen .

Good luck!

So, right now what are the advices for not having pink frames? Today I'ven using the eosm with a trascend r95 card and got like 2 or 3 pink frames per minute, can it be most likely the card? Because I have a sandisk extreme pro too, but it's on another camera and would have to do a backup of it to format it and use it with the m

In what mode did you get pink frames, MCM Rewire, 2.5K?
It's most likely the card you're using. It has good Read Speed, but the Write speed ain't good enough. SanDisk Extreme PRO is like the Boss, stick with that. Lexar Pro 1000x cards are also good.

Tell us exact mode and settings.

Fun stuff. I recorded in a very bright setting a couple of days ago with hd1080p mode with 1736x1158 14bit 24fps. I had one corrupted frame. Yikes. Thought only higher framerates could cause this by now. Next time I'll enable kill global draw. Should keep it safe from pink frames.

Sorry, forgot to write it, mode is 5k anamorphic, 10 bit 24fps
I don't seem to get pink frames on 1080p
I'll test with the extreme pro to see how it goes
What does the kill global draw option exactly do?

Thanks a lot Danne and IDA_ML for the info!

Lua can be used to modify shutter, iso, other settings. If frsp enabled shouldn't make no difference.

The reason I ask is because on my 550D the FRSP (or even Simple low res silent pic) doesn't work with exposure bracketing nor focus stacking. Only single photo is always taken. But I also experience the bug with a black screen after FRSP shot and have to always return to Live view by half pressing the shutter button again. So maybe FRSP mode is really much more limited on 550D. That is great if it works with bracketing and other features on EOS M.

Longer shutter times than with 550d. Don't think so but not sure here.

What about the fastest shutter speed? I wonder if I could get at least the same results as 60D here (from 1/10 or maybe 1/30 sec to 5 sec):
https://www.magiclantern.fm/forum/index.php?topic=12523.msg122956#msg122956

The reason why I avoid using FRSP is that this mode does not allow proper aperture control on some of my best lenses and I cannot stop them down enough for reasonable depth of field.

Yeah, that is a big limitation of FRSP. Actually I play with the idea of getting a used Nikon lens and adpater because Nikon lenses (I don't know if all of them though) have a little lever that controls the aperture. Some of the adapters make use of it and allow you to move the lever (with a bigger lever or ring) thus manually setting the aperture. But of course the disadvantage of manual lens is that you cannot do automated focus stacking and if the adapter is not perfect there might be a little bit of play.
Do you have any lenses where the aperture actually worked with FRSP? If so, could you please state their full name?

I prefer the 5k anamorphic setting in the Movie mode instead.  The image quality degradation compared to FRSP is negligible and not perceptible unless you pixel peep at 100%.  Even then, you will barely see a difference in image quality.

That sounds interesting. I looked a bit into it and if I understand it correctly the anamorphic 5K setting just crops the photo (or frame).  What exactly causes the slight IQ degradation compared to the FRSP? Is it just the crop (resolution) or is there any bit depth degradation or even compression? This might sound stupid but I am gonna ask just in case :) ... is there any stretching or transformation applied to the image in camera?
What would be the highest resolution photo I could get with this anamorphic 5K setting? If there are any downloadable .MLV  shots of the same scene and with the same exposure (one taken with FRSP and one taken with anamorph. 5K) somewhere, that would be excellent.

Are there any other problems (vignetting, artifacts, ...) with silent pics on EOS M (FRSP or anamorph. 5K) to be aware of like described here?:

https://www.magiclantern.fm/forum/index.php?topic=12523.msg122916#msg122916

Plus there is a strange top-corner vignetting after 1/30 which seems it exists anyway in the all pictures in every exporuse although it isnt always very noticeable.

Again, thanks a lot guys for your help! I appreciate it. I am sure it will be useful to other users as well. I asked a lot of questions, don't bother with all of them if you don't know the answer, I will be grateful for any info.

I really like that, a nice but of extra resolution, though it's like 5:3. I tested it a while back on the M2 with Nikon G lenses, it was nice. I don't remember the dropped frame stuff. May have to test it again.

It's kind of perfect for real estate filming grabbing the full sensor.
