hey guys,
i got a eos m recently, but i don't know how to downgrade the firmware from 2.0.3 to 2.0.2.
The links in here to downgrade are all lost. Is anyone can give me some direction?
Thanks a lot! i really want to install ML to record video!

Basic instruction -> https://www.magiclantern.fm/forum/index.php?topic=18941.msg179783
First chapter applies, you don't need to play around with EOS Utility.

Firmware found in
Top of page -> Downloads -> Download nightly builds -> EOS M -> Installation or Useful Links

Checked links. Everything is fine. If you have troubles using links, instructions, tutorials: Please link those!

Hi!

I am trying to use my M as a streaming webcam with 1080p and I am lost.
Using the build crop_rec_4k_mlv_snd_raw_only_2020Nov20.EOSM202.zip I was able to get "clean" HDMI out of my camera but I have large black bars around my image, top is thinner than the rest (tested with HDMI-capture as well as plain TV)

Reading multiple posts, I assume it has something to do with the different aspect ratios and the structure of the live view itself, but to be frank I lost track which component is responsible for what (different recording resolutions with different crops, I got confused)

  • First: Is it possible to get 1080p liveview via HDMI out?
  • If so: Can you provide a link to a topic/post were I can find additional informations
  • If not: What would be a decent workaround to get the best result

Thx in advance!

Check your resolution or aspect ratio. What are they 16:9 / 3:2? Also in Advance HDMI settings in ML Menu I think from memory bottom Tab 6, change from 3:2 to 16:9/16:10.

Hi!
playing around with the Movie settings presets, raw video and ratio settings did the trick (so now only minor black bars left and right, which can be an issue with the capturing device) Funny thing is, I can not undo that, thus I am not sure which setting was the right one for me.

Nevertheless, thx for your help

2.5k mode is still broken in HDMI, its unproperly squeezed so takes less than half of the screen despite being cinemascope, its thinner than 4:3 and on the left side on monitor, on the right side there are random lines dancing.The same in 2K mode 1920x1280.
I tried to change 2.35:1 everywhere , in ratio and raw menu but it didnt changed anything.Nov20 build.
I think last time everything worked fine with HDMI was in september builds.

2.5k mode is still broken in HDMI.
Try enabling the 2.5K & 2K Modes from the preset menu by tapping on the screen once and see if that works.

It doesnt help in my caqse, theres always 1/3 of the screen with squashed liveview with about 5:2 aspect ratio and rest of the view is random lines .

BUT
I discovered something...  :D  To record longer in 2.8k and 3K modes go to expsure ML menu and set global draw to quickreview, and some magic will happen, i managed to get over 2 minutes in 3K mode.
Danne is it possible to expand this mode to 3.5k ? Maybe it will work ? Cause if i can get over 2 minutes in 3K  ? I got orange icon and could go on and on.
3000x1276 and no pink frames, its amazing cause i thought that 2.8k is absolute limit but here it records without problem when i enable quickreview.
I know theres 4K but its different than 3k crop, cause this 4K is in 8fps only for me unlike 3k.
Ah so the 3K is in 20fps , can it be in 24 ? Theres sudden drop to 20fps when above 2800 , when i set 25fps in 3k mode then it drops to 2800 as well.Considering its quite stable for over 2 minutes, can we go higher with fps above 3k mode ? Its not like im getting only few seconds, its long and stable.

I think quickreview is more or like giving the same result as global draw off. You can test by selecting kill global draw under raw video menu.

I see, does camera impose that fps limit above 2.8k ? Can we get higher fps somehow when recording is quite stable for over 2 minutes ?

YOu can test yourself. Decrease reg_6014 in the submenu. Works for 25fps at least when set_25fps is enabled.

Yup, 3 seconds in 3K with 24fps.

OK i got 10 seconsd in 3K , 23.somethinalmost24 fps  but i adjusted both regs
-220 for 6014
-34 for 6008

When i went lower with 6008 then image got pixelated and then totally glitchy, but 6008 helps to get extra frames .
Raw detect error with 6008 set to -35, You think theres something more in there, or somewhere else that could help to get more time ?
10 secs is not bad tho.
But after more testing i think it was just luck, still getting about 3-4 secs
Ah but i have black border on right when using reg 6008...
Anyway 4-5 secs of real 3k raw is still great for this little cam, just changing reg 6014 to -300 works to get 24fps in 3K for 5 second clips.

Yes, usually possible to gain a few more fps but not continuous. I choose to maintain a somewhat continuos preset.

Maybe Zeek would get more time in 3K with 24fps and his 512 GB card that was fastest so far... If its better ill consider buying it.
Ive got 128gb sandisk pro with 64MB/s write speed in bench 192hz , his 512 has 68 in 240.
But his is weaker in 192hz with 62 MB/s , i get same 64 result in 192 and 240 but i cant recrd anythin in 240 anyway, it stops.

Maybe, maybe not. There's a line where increased fps will affect overall sd card speed no matter how fast the overclocking is.

Zeek had higher data rate in 240hz , from this post:
https://www.magiclantern.fm/forum/index.php?topic=12862.msg231732#msg231732      Mazybe he would get 10 seconds in 24fps 3K mode .
If he needs info on how to do it + just go to Movie panel in ML, touch presets to expand it (dont press set) and there you have advanced mode, find register 6014 and change it to the left so its - 300, you have 23 somethin in 3K mode, you can go to -310 for 24fps.
I think his card would get better and longer record time.

Does anyone still maintain and update the ML of Canon EOS M2?

Well after testing a whole heap, my 2 cents is that the 240Hz patch is not reliable enough. In 2.8k 24p 240Hz I got a max of 8 minutes & now testing 3K 24p override, I got a max of 14 seconds with 240Hz patch. However after a few recordings it will go down to about 3/4 seconds with the same patch.
A break is needed and then it will pick up the pace again, but then the same pattern will occur. So then again....
I still think though 512GB is an amazing SD if you travel a lot and plan on shooting heaps of 2.5/2.8K Raw footage. 😎👍

Overclocking doesn't work well with all card types. I have some cards performing superb without overclocking and failing if put to the edge. You have to run some in-cam benchmarks to see how stable a card reacts. If a card stalls/stumbles often and unpredictable while benchmark runs (and it will only happen in write cycle): Nope, won't do with this frequency.
My good old 128 GB 95 MB/s Extreme Pro is outperformed by some mere Extreme in 240 MHz.

Hello! Thank you to all involved in this wonderful project. I have noticed something odd when attempting 5k FRTP using Zeek's settings for continuous video, with the Nov 20 build. The recorded video seems shifted to the right, compared to the framing I see on the monitor on the back of the camera. I thought I would mention this here. I have not yet compared this with another build yet but I will attempt with the Oct 24 build.

Thanks again to you all!

Ah, I meant the Oct 23 build, but I can't see it available for download. I will use 1080p MCM Rewire instead, this works fine!

How much shifted would you say? Could you post a few visual examples? Unable to find time to do tests atm.
