Had time to test 50D with UHD (3744x1080 23.976) , I did a better setup on the tripod , filmed my flowering plum tree (before there gone) Canon EF24-70mmL 2.8f @ F8 800ISO 1/48th second .
Process thought After Effect ACR , I wanted to use mlv app but it kept clipping the highlight & turning them Pink so I use A.E. , export to ProRes4444 and uploaded that same file to YouTube (2GB)
Very impressive image this may be the best crop_record next to the 5D3  :) watch on chrome for the full UHD/4k stream . I don't have the crop_rec working yet for the 50D I just used the ADGT_GUI.mo

Nice work. I had concerns about 50D sensor size, but with 3744 resolution, the crop factor is actually pretty good (36/22.3)*(4752/3744) = 2.049x, same width as micro four thirds, only a tiny bit smaller than what you get on 5D2 with 3008 pixels, 1.867x

I think it may be more practical if you increase height and decrease width though.

I see 50Ds for 99 pounds :o

Very nice @reddeercity. Let us know when you release your code. I have a 50D so I could help testing.

Yea I plan on it , I can do 3200x1200 @ 23.976fps  but I have a problem with the vertical offset right now (still working on it)
3744x1080 @ 23.976 was the easiest to achieve with minimum reg's being applied & of course I needed a simple preset
to code to make it easier for me .
I see 50Ds for 99 pounds :o
Yea 50D are cheap and a lot of them have very low shutter count , they came out in mid 2008 to 2010
but in the time 5d2 came out & less then a year later the 7D so I bet a lot did a upgrade to 7D or 60D etc. ..
specially since the other had factory video option  https://en.wikipedia.org/wiki/Canon_EOS_50D

Back Working on 5D2 3x1 4k (4096x590(4096x1770) 23.976fps)
But it's super buggy right now , but if you feel brave check it out .
3x1 4K is the (1920 1:1) in the crop_rec menu (I haven't change the name yet)
Please note !! you need to adjust the cmos[1]hi & cmos[2] in the advanced menu of crop_rec  like the image below

this needs to be set before you enable the crop_rec , after that start in 5xZoom (without crop_rec enabled) you should be  @ 2144x1078 that this point .
press the half shutter to refresh , now go to the crop_rec menu , select 1920 1:1 , press half shutter  , then right after that cycle thought the 5xZoom button
until it's at 3x3 then the 4096x590 should come up . Yea I now it's a kind of a pain to get to ,  but this is just my first daft .
The cmos's for some reason are not being applied correctly , I need to go over it again .
 
Tomorrow I'll make a quick setup video on how to enabled it ,
Remember ! this is Very Very Buggy !!! and my crash , the screen may turn black etc. ... you guy know the routine , if breaks you get to keep all the parts .

Also note , that the advanced crop_rec menu setting for 3x1 4k will not work with the 2.6k 1x1 , you need to disable those 2 setting back to "0'

For now i have this bug:

https://drive.google.com/open?id=1PkNXq2j6tPX7U9_2yzlzqn_oI2ZuJWE4

The same story if I off the crop rec and raw modules and after that press liveview button

Ok , here the video to set it up 4k anamorphic on 5D2 , *Note *only Load mlv_rec & crop_rec that's it , just fellow the video & like I said it's very buggy . Even show how to get out of the black screen

Shot this on my new/used 50D in crop_mode @ 1920x1078 24fps  ;)


Edit:Here a short 11 second/30Mb 5D2_4096x1770_24fps_M31-1952.mp4

You need to select 4096 in the raw movie/mlv_rec sub menu .

I think i found the key=) just get the 4096... It needs to set the maximum resolution possible in raw module before you go x5 the first time

@Reddeercity, Yes, thanks =)) That's my 4096x1770 footage. Looks so cool...

First test looks great, but there is a black bar on the right side in all test footages.

Continuous recording is really nice, so is there room for more?


I also have good news:

I've tested with 10bit (continouous), 12bit (around 630 frames, ~26sec.)
and 14bit (around 250 frames, ~12sec. and with real-time liveview!! (grayscale) -> low frame, but it works!)
And all tests with audio;)

Impressive resolution numbers, but it looks aliasy and not that sharp. The best mode for quality is still the 3008x1080, so I think squeezing more out of that would be the most effective investment of time on 5D2 (just my opinion).

3.008*1.080*23.976 = 77.9 MPix/sec, there's still a bit of vertical resolution to squeeze if the limit is 96 ;D

@Bender@arsch
Wow... You have real-time liveview? Only when shooting 14 bit?
@Ilia3101
You right, but i think even though it doesn't look too sharp, it is very cinematic because of less crop factor when shooting 4096...

I agree it's cinematic from having less crop, definitely good for people shots with bokeh, but other things will moire a lot.

@Ilia3101 You are right... Maybe, i think the best way is to combine 4096 x 1770 (when you need Shallow Depth Of Field) with 3008 x 1080 cutting it to 2494 x 1080  (when you need more detailed and quality picture). But is there any sense? I'm gonna make a comparison side to side, shooting 4096x590 and 1856x790

Another shot. I've tried to imitate 16mm film (starts from the 9th second). After, understood that it was a bad idea,  but render time is too much for do it again =)
unfortunately, i don't have any ND filters, so the aperture here is 11....

And of course, i noticed that the image is captured from the top of the sensor (it's not centered).
@reddeercity, Do you think that the best way to unsqueeze the preview (when/if it will be unfrozen) is to use an external monitor that is able to stretch the image vertically?

Yes there a unsqueeze anamorphic preview mode , but only work in canon liveview , I had it working in old test a few mouths ago .
Need to adjust the preview reg's agian to get it to work , I'll look in to it .

3.008*1.080*23.976 = 77.9 MPix/sec, there's still a bit of vertical resolution to squeeze if the limit is 96 ;D
You need to include the OB range , even thou the final resolution is 3008x1080 there more area to consider here .
Code: [Select]
Default Crop Size               : 3016 1080
Active Area                     : 52 160 1132 3176
as you can see the real size is 3016x1080 but because of mod8 rules the mlv_rec only save as 3008 .
Now  in the raw image dump to dng you can see the OB area included now  3176x1132 , the 52 160 is the crop offset
52lines for vertical & 160 lines horizontal = 3016x1080 (mlv_rec cropped 3008x1080) .

So let figure out the math for the over all size with OB to MP/s
3176*1132*23.976 =  86.19 MP/s so there less then 10 MP/s left for total available of 96 MP/s so there
must be a little overhead there in headtimers , so I think that really the limit unless there a way to increase the frequency
from 24MHz to let say 32MHz , that would give us 128MP/s good enough for 3520x1350 @ 23.976(114 MP/s) with OB it would be (3680*1402*23.976=123.7 MP/s)
let push it to 48MHz per channel (wishful thinking) 48x4=192 MHz now this is in 5D3 territories 4096x1770 24fps (with OB area -4264*1822*23.976=186MP/s)
With the 3x1 4096x590 in mlv_rec before mod8 rule 4120*591 , with OB area it's 4280*609 (4280*609*23.976=62.5MP/s)
So yea I can go wider but as I go wider the vertical get reduced in proportional to the wide e.g. 5632x416 =5632x1248 (4.5A.R.) , too wide


M01-0022_frame_224.png

But I can increase fps , I had 4k anamorphic up to 29.97 fps maybe there a little more there like 35fps
did the math and 4280*609*33=86MP/s , so  33fps looks like the limit , I maybe able to push it to 34 or 35 fps

Do you think that the only way to choose the composition and see what you're filming is to use x5 canon liveview (without understanding the borders of the frame? ) maybe there is a way to unfrozen the liveview even if it will be 2 or 3 fps?  :P OR maybe use canon preview but in no magnification mode (for make exactly the same anamorphic frame from black paper and stick it to an external monitor for example, so u can understand your composition. Hope I wrote understandable, heh. And how'd @Bender@arsch get low frame real-time liveview?

Awesome work you guys do !

I also get inspired by all the good videos, especially by Ilia Sibiryakov.
So I bought a used 5D and went for holidays to fool around a little bit.
The newest build worked pretty well for me.

I hope you guys enjoy

@shiro_hh

Hi, here at 2:34 - this footage with kite in sky also shot in 4k? And what was the FPS and shutter speed did you use? Every moving objects are so blurred. Also what was the lens? Think you should buy another one if want to shoot in 4k, because in my opinion the lens resolution here is not enough for it.
