Would be nice to go over above build so it can get merged into master branch. What is needed?

cdric introduced a fix for the flickering in dual iso, but it was corrupting the exported video.
Tried to contact him but no answer.
I removed some bits of his code to get the export working, but ideally it should be fixed instead of partially removed, or removed completely.
We never merged the optimization because I got feedback asking for more testing, but didn't have much success when I look for testers 

Any metrics/benchmarks for Dual-ISO footage in 2160x1080 (1x1) conversion to medium quality H.264? OP (on discord) got about 90 minutes for 10 minute footage.
SSD, AMD 7745HX and according to OP no thermal throtteling.

Could you/OP please try this build and post your results?

Awesome work, thank you! The embedded videos work better now, before they were too big, taking the whole width 

One more: youtube embeds are broken.

Vimeo's too

I'm just commenting on the 1x1 images, to focus on sharpness.
Both samples (on your second post you swap 1x1 and 1x3) are as sharp as your lens is.
What I notice is that you didn't fix Focus Pixels and that all your samples are too dark, so there will be a lot of color noise.
If you want a moody look but not noisy, expose brighter and turn exposure down in post. Use the histogram to help you with exposure.
You can also apply the chroma noise removal in MLVApp.

I like the new design, I wish there would be more smileys to choose from 
Still details to polish, like people is pointing out, but good feeling overall

Thanks for explanation. I have a 35mm f1.6 CCTV lens. When I used 1x1 crop, I get just blur blob like bokeh on the screen. Would you mind shariung your configs while using 16mm C-mount lens to film such a gorgeous 4:3 video? Thanks

I'm afraid this is not a settings problem. If your c-mount lens cannot  focus, you can try adding a spacer. It's like a small ring that will move the lens further, hopefully improving focus...

+1 for sample footage, impossible to tell otherwise.
Just checking: did you shot full manual with other cameras before?

If only happens in 3x1 modes, it's normal. Try 1x1 modes if you want sharpness

Wow that is really nice. Thanks for posting. Does this 16mm lens causes vignetting? I have C-EOSM adapter, but mounting a C-lens does not show up anything. Maybe wrong adapter from Amazon! Which adapter did you use?

Hi, thanks. I think there is a setting on the EOS M to allow recording without lens, which is necessary to mount lenses without electronic contacts. Try that if you hadn't already.
At least you should see light, no matter which adapter you are using.

Most c-mount lenses will not cover the entire sensor, that's why the 1x1 modes are so useful, they only use a small part of the sensor, so the lens protection covers all the area in use.


With this 16mm you will get an image like looking through a tube on 3x3 1080p for example.

There are many different c-mount lenses and it's hard to tell how big the projection circle will be, so I just buy the cheapest ones so I don't feel bad if they don't perform too good

New build again.

- Seems I fixed histogram check automated and without speed penalty.

The camera heats up faster with RAW histogram enabled, quite CPU demanding, but good to know it works now if I ever use it 

Really nice footage man. Where to buy this lens and adapter?

Thanks, I got it on eBay, but you have to be patient because there are really ridiculously high prices. A fair price in my opinion is 50/60€, I wouldn't pay more...
The adapter for c-mount lenses is easier to find and very cheap (look for "c-mount ef-m adapter")

[New build]

New build

- When Histogram and RAW-based is enabled 14bit preview whie in other bits is turned off working as regular 12,11,10bit preview. Fixes the histogram issue mentioned by @gabriielangel

Needs some testing.

Will test later, thanks!!

Another 1620p sample, this time with a tiny Cosmicar/Pentax 16mm f1.4 lens (the one on this post)

Yes, but I don't see a 1920x1080 one. The closest is 1920x1280 (or maybe I am under hypnosis, or just blind)

In theory you can use the 1920x1280 and set a mask to hide the extra pixels on top and bottom. You can also try to set the aspect ratio to 16:9 on RAW menu

Yep I did see the change in commits, but that requires compilation, right?

Is there any document that explains how to compile your repo in Linux? The Makefile at https://bitbucket.org/Dannephoto/magiclantern_hg_02/src/master/Makefile does not specify about compiling for Canon EOS M. Or does 'make eosm` or `make EOSM` or make `eos-m` work?

Thanks!

You don't need to compile, I guess Danne forgot to upload the binaries 

New build added:

- Preview for 1620p shows more or less full realtime preview. A bit stretched but fully usable imo
- Added a More_hacks switch under Customize buttons. When selected it will always stay enabled if selected in RAW video. When recording user can´t change aperture or iso while filming. Turn it to OFF and the hack will be disabled while recording when using U/D and INFO button as before.

Pure gold! Best solution to the "more hacks" dilemma

Would it be an idea to reduce resolution a bit to get more stable 12bit recordings?

On a 512GB extreme pro 200MB/s I get green with 12bits, never got a forced stop even though I always ETTR. Many times I can use 14 bits 

Note: I have live ISO and aperture not assigned to get the extra MB/s

I've tried both and agree that making the preview smaller is worse than slightly distorted.
I guess it's not easy, but on TEST 2 the image while recording extends till the top, using the space of the black info bar, but doesn't extend till the bottom. If it could take the entire height, like it does on the current version, the image will be less squished and the preview will take the entire screen with "kill global draw" enabled.
I'm sure this is one of the "easier said than done" things haha 

In any case, it's already one of the best modes and super useful, it's giving the larger vertical resolution from all non-anamorphic settings 

So if I'm right, 200D would be a game changer in DR!

You are right that it will be better without dual ISO, but I wouldn't say that the difference will be so important, we'll see
https://www.photonstophotos.net/Charts/PDR.htm#Canon%20EOS%20200D,Canon%20EOS%206D(ML),Canon%20EOS%207D(ML)

I think that would make it the best ML-enabled cam in terms of dynamic range

The only downside is that those cameras were more ISO invariant, so they don't get that big boost that dual ISO can give. Also the 200D dynamic range falls very quickly with higher than base ISO

Congratulations!!
Big thank you to the incredibly talented and wise devs that have the motivation to keep the ML project alive after so many years and still bringing the magic to new cams 

The Info button is mapped from the start in this build. Go to customize buttons and set it to OFF, that might help

I forgot to mention that I have "kill global draw" enabled, 12 bit and only zebras

Could you test this build @iaburn?

I tried a few clips and had no issues with the new build, but it will need more testing, as I only had this problem twice 
Thanks!

This build is getting super polished, thanks Danne! 

I was recording on the new format yesterday and got a couple of shoots "broken". One was green, I just deleted it, and another one got corrupted over time, I never saw that before (example below).
Any idea why did that happened?

The * is assigned in the Canon Menu's Custom Functions(C.fn). In C.Fn IV menu 5, some settings transfer Auto-Focus to the * Button.

But Just enabling "Preview Toggle" Did the trick! You can then use the * Button to see the whole frame.

I couldn't find a way to remove the autofocus from the half shutter and leave it only on the (*), but it doesn't bother me much because I just realized that enabling "Kill global draw", the black info bars on top and bottom are removed and it's a perfect 4:3 real time preview
It would be even better if we could simply hide this info bars, but keeping global draw so the zebras are visible, but I can live with that
