Cool shot!
So, you tell that half screen canon preview is not correct? Or it was missunderstood by me. Anyway it works good in 3x3. So it could be used in 4k.
Wanted to ask, does it influent to crop_rec or raw module which kind of battery or card do you use? I use a battery grip and notice (or it just seems to me) that your build work different ways depending on which battery slot do I use, or use I an external power or not.
And also by the way I killed another Lexar 32 1066x I don't know why. I changed the battery and the camera refused to turn on. No blinks, screen doesn't work.. i've changed the battery several times and got the massage: card not formatted. So I unable to format it from any devices. Just test report...

@Reddeercity, please could you port this halfscreen liveview to the 4k preset? It's so cool

@Igor_Braun

My way to activate 48p is (preview Options: Auto):
1. enable live view
2. set your Settings (manuel mode: shutter, aperture and iso)
3. press play 2 times (wait 2-3 sec.)
4. press "+" (wait 2-3 sec.)
5. repeat step 3. and 4.
6. enter crop rec 48p in ML (press half shutter to exit ML) -> and you will see a half frozen live view (top is liveview and bottom frozen) -> this is correct
(7). sometimes it doesn't work and you must disable 48p first (press half shutter to exit ML), and repeat step 4. - 5. or go back to step 2.

If you want change shutter, aperture or iso -> disable crop rec first and go back to step 2.
-> if you forgot disable crop rec first (blackscreen!!) -> disable live view, disable crop rec, enable live view and go back to step 2.

Set correct shutterspeed is important!  1/33 --> 1/58,       1/41 --> 1/86,       1/45 --> 1/100(ML menu)       1/50 --> 1/130,       1/64 --> 1/320,       1/82 --> error

Ah.. I saw a half frozen live view everytime. Is it correct? I'm going to try to shoot something

Edit:
It works

It's wonderful! I mean the real-time preview in 48fps!!

But in my case it works if i select 1/62 before enabling crop_rec, if i select 1/50 it freezes, but anyway camera captures normal life video

@Reddeercity, I've tried everything i know to activate the 48fps mode but couldn't get into it. Will try again tomorrow. And could you tell how to change shutter speed from 1/62 to 1/50 (or 1/48) in 4k mode, and if it's possible to change iso in 4k?

@Reddeercity
I also wanted to ask you, what do you think about 3840 × 2160 (16:9) 8 fps 1x1 preset? It must be very very useful for real estate shootings with tripods, sliders, or gimbals.

1/48 preset (i used a very cheap lens, so it's not very sharp)

https://youtu.be/Zb0I6CIcRzM

Look, once again I would like to tell about 1/130 shutter and rolling strobe effect and also, look at the cat, it seems that on the video everything is a bit faster than in real life.
1st footage - x2 slower
2nd footage - original speed
and then the same footage, but x2 slower

And these are 4k footages.
By default, the shutter speed in 4k preset is 1/62 now, and in my case it unchangeable. Strobe effect is terrible (look at the last footage)
https://youtu.be/e83C51ZCw8A

More likely this --> 4k (4096x1770) half framerate of 24p (12fps) in 1:1 (should be close at least 10fps I think)
Then this -- being back 3K (3008x1080 maybe with a little more res)
and this 1920x1080 @ 45p in 1:1(3x crop_mode) 
The last one will be 1x3 4k , as this need my full attention (adtg hooks need to fixed for d4 cams)
Then I can move on to Lossless .

Can't wait for the last one with canon preview...

And maybe it will be better if you decrease the horizontal res of 48fps to 1610 to achieve the same 2.34 aspect ratio? Maybe it will give you even more fps..

Today i was testing FHD in the streets but after several recorded clips all the modules disappeared.


So i got to my place, installed 48 fps build to my other card, went to the street again and got this:
https://youtu.be/oTB7ibj028U

Awesome, awesome...
Tested 48FPS

48 fps original:
https://youtu.be/FtUpYJEYAkM

48 fps 2 time slower (23,98):
https://youtu.be/IwVu60D5N8A

Also, i was excited about less rolling shutter but noticed that it's pretty the same as in regular 1856 23.98 fps
Want to test 1x3 4k so much. And compare it with 3x1.

@Reddeercity Why do you use 1/130 instead of something like 1/100. I see a kind of strobe/rolling effect on the video. I think you may avoid it with 1/100

https://youtu.be/p2jvRNGMUzc
Got those vertical lines in 4k, but did everything that @Reddeercity said for eliminate it before shooting. I think it's my camera issue.

@reddeercity i use only manual mode and yes, only safe stable night build for 5d2 when shooting events. I also think, that it's because of the camera, not ML. Today was keeping testing ml and bricked my lexar 1066... Just turned off and on again the camera, and "card not formatted"   text appeared. Cant open and format it on camera and PC, i'm totally unlucky... But will keeping testing every new stuff anyway

@Reddeercity
@OlRivrRat

The thing is i don't use experimental build when shooting events... And don't turn on raw modules. It started to appear from the moment i installed an experimental build the first time (including when don't use ML or when i use stable version). Also with it, i have strange problems with turn on lifeview

@Danne, Hope it's the problem, that you mentioned. But which code should I hand you and where is it located? It's regular h264, not MLV.

@Reddeercity, also would like to ask you. I just came from shooting event (was a college party). And got a bunch of videos with vertical lines like this:

To solve the problem i needed to press rec and stop several times.
Is there any way to avoid this problem?

Understand what you mean. But if take a look more carefully it's noticeable that 1160 is more detailed while 790 is more "digitalized" so 790's one looks more sharp because of it. I think this happens because of squeezing the full frame image to 1856x790. And also as Reddeercity said, the image of 1160 is captured from the lower half of the sensor. The center of a lens is sharpest place...

@Reddeercity, 48 3x3 it's a full frame image with 48 fps?
PS:Waiting for the possibility to compare 3x1 with 1x3 4k anamos side to side, hehe

Did a comparison of 3 presets: regular 1856x790, 2784x1160 and 4064x590.
Before shooting i zoomed with the lens according to the crop factor of each preset.
Critically focused each time.
Lens: Nikkor 70-210 f/4.0
Aperture: 5.6
Iso: 400
In MLVP i set the saturation to 0, exposure to +3 and chose Blackmagic profile.

The whole images looks like this:

1856x790:

2784x1160:

4064x590

Zoom in:


2784 one came brighter than others, so let's level them by brightness:


4064 is my favorite although it has a lot of artifacts including a bit of digitalizing effect because of squeezing. But it's sharper than 2784 and has less crop factor, so it's more cinematic.

PS:
@Reddeercity
You said that the image is centered in 4k now, but look, when you set 9 and 34 with your latest build it looks like this:

And if you set nothing:


When did the cropmark I was using this latest build.

@reddeercity, correcting the preview in 3x1 preset using anamopric feature would be a good solution. I was looking for the code location but did't find it. Will check the tweaks.c, thanks! It's interesting for me too.

And also I noticed that if you select any of anamorphic view corrections it doesn't affect the image in the case of 4k anamorphic preset

@Igor_Braun - Getting video unavailable error message.

Error fixed.
PS: I set the Blackmagic profile in MLV Producer, decreased saturation from 100 to 56, exported to png, then added a little zoom in effect in editing program and rendered that to Avi uncompressed with 4064x1770 res

Today I was late to the park and before sunset was able to shoot only one single shot using the new build...  Like the resolution so much and there are no side bars more.

@reddeercity
That sounds so exciting... Want to try 1x3 so much.
So, for now, this evening-night (because I haven't ND filters yes) i'm going to test out 3x1 in a city park and compare it with 1856 again =)
Will share the results.

I made the cropmark, that allows you to view the composition without vertical stretching before you turn 4k anamorphic on with certain cmos hi and lo settings.
https://drive.google.com/file/d/1iOvXj_5aFVZO01stEWZTNP7M1AB6b_qX/view?usp=sharing

Works well with the "magiclantern-crop_rec-4k-3x1_2784x1160_1920centered_7.54pm-5D2-eXperimental.2019Jun20.5D2212" build.
The order is:
1. Turn on the "4kanamo_01" cropmark
2. Set the composition
3. Turn off cropmarks
4. Set cmos[1]lo to 9 cmos[1]hi->63
5. Enter the 4k anamorphic preset
And you can shoot now with exactly the same composition
^^

PS: @reddeercity, i found out that without setting the Hi and Lo CMOS you get almost bottom centered image... and more to the left. cmosLo =9 it's also not perfect but more or less centered as well as 63. CmosLo 11 is too much to the down.
Also i'm trying to do something to make the liveview work well but without any success.
Theoretically is there any way to use regular canon liveview during shooting 4k anamorphic? We can simply glue a piece of black cardboard cut out in the center in the form of the preset. I'm talking about that because saw the 4k anamorphic preset description "To use this mode, exit ML menu and press the zoom button (set to x1). So, does 4kanamo work in x1 zoom mode? Or this description is not correct because it's from any old preset?

@Galterius

I'm getting those vertical lines as well as "white and black long time balance (for like a minute) auto adjustment color effect" for a few months already since I started to test all these experimental builds. And not only in raw mode. And also when i remove the ML bootflag i keep getting it sometimes with regular h264. Yesterday i got it during my work. I think for now there is no issue to resolve the problem. Only play button double click, or press rec for a second and stop... or restart the camera...

I'm very close to having 4k Anamorphic (10bit raw 4064x590->4064x1770) coded , still having a problem with "pack12" applying to cmos[1] , but there no problem with
the 3x crop preset 2784x1160 , I need to write some more yet , almost there 
Here a quick test , from my back yard yesterday , MLV App -> to 10bit dng's ->import in to CS6 Adobe A.E. , grade with ACR ->export ProRes4444->upload to YouTube
To see the 4k stream watch on chrome ,
FYI: ISO 100 1/50th , Canon EF24-70mm f2.8L , crop factor 1.38 shot at 24(33.12)mm & 70(96.6)mm @ f8  & ProMaster Variable ND for video set to ND3

Sorry for the double post of the Video  thought it should be here also .

@Reddeercity, sorry for living one of your message without an answer. Had difficult days...
This is an absolutely cool resolution on your video, very noticeable on the bricks . Just tested out 4kanamo preset compared with 1856 one in real life and noticed that 4kanamo is really much more detailed than 1856. Actually, before i didn't believe that there is a real difference...

@reddeercity
I think I could find out the settings for center the image vertically too.
There are some black bars at the sides (especially at the right side), but not too much thou.
So, the settings to center 4k 4096x590 preset horizontally and vertically are:


And it need to apply them before switching the crop mode on as you said.
There is a  lot of moire, but personally me I don't really care about that.

Will try to find combination for avoid the black bars

@Igor_Braun , to center the 3x1 4096x590 on cmos[2] in the advanced crop_rec menu
instead of

Code Select Expand

0xE
select

Code Select Expand

0x6E
that will center it from what I see here

Oh, thanks, and what about CMOS [1]lo for vertical centering?

@reddeercity, I'm keeping break my brain with configuring my VB Ubuntu for ML, heh.. Now I have all the source files (thank you for helping me on that thread). But still, have a lot of errors.
Look, actually, i started to do it all only for "centering" you 4k anamorphic preset for comparing it with "regular" 1856-790.
The reason I can't do that now is that in 4096 preset the image is being captured from the left top corner so we have distortion and the image is not as sharp as if it would be captured from the center at apertures like 1.4, 2.0, 2.8.
Could you please center the image capturing in the future?

I really DO believe in this awesome 4096x590, and actually believe more than in 1632x1828 @ 23.976 fps (1x3), because in my personal opinion, in this case, the true horizontal resolution is more important (but would like to try 1632 also, of course).

You, David, do really great things...
