Very impressive how quickly you have made progress on the 50D!

Looks like good dynamic range and very clean, maybe it has better quality than 5D2 ??? Sensor a bit small though...

I tested the new crop module and at the beginning I thought everything was great, no stripes or anything and I can change the Shutterspeed as I want, but ... later i see "sometimes" (not everytime or always) false greenish blacklevel for some sec.
Yes, I record ALL in manuel mode and i have testet the 1/48 shuterspeed too -> same resultat

Btw. if i set shuterspeed to 1/33, it set to 1/26 -> good for low light

Here a short testfootage, no correction, F11,3, iso 100, 1/48, 10bit (112 black, 1013 white), temp. 5800 -> false blacklevel here at the beginning :

I fixed my own problem by changing only one setting:

Do not enable overlays in mlv_rec (default is disabled while recording raw video)
Now all works great, thanks Reddeercity!

Your 50D Projekt sounds realy good;)

btw. can you make a Build with both latest crop moduls in one?

@Reddeercity

You asked for the original mlv file to see aliasing and moire in 2.6k crop mode...

her is the original mlv file to download

Side note, with this and with 3k build, when formating card in camera, it delete ml from card

Downloaded 04-07-2019 CROP_REC.MO for 5D II.  Un-zipped the .RAR and installed to Module to the CF card.  I'm getting an error when loading.

Question.  Does Crop_Rec.MO not go to the Modules Folder?

I get an Err for all Modules when loading Crop_Rec.MO.  When powering off, the Error says it failed to link modules.

-----

Proudly own a 50D...  Will test functionality of further Crop_Rec.MO developments...  With your help.  Thanks.

Thanks got it , Ok now I see it in the Blinds in the windows .
After carefully examining the file I found user/cam setting issue problems.
Your shutter setting is far too high (very short exposure time)



You have 1/362th second @ 24 degrees !
This well cause aliasing big time , you should have 1/48th second @ 180 degrees .

This the metadata from my camera set correctly , note shutter angle & aperture .


Please take this with a grain of salt , you need to understand better shutter angle & aperture
because they work hand in hand , you set the lens to f2.8 and reduce shutter angle to get a more in focus (1/362th)
where you should have closed down the aperture to let say f8 increase shutter angle ( 1/48th) = the same focus .
and if you have 1/362th shutter you didn't set the camera up right .
If you follow the instruction on the first post of this thread you should end up @ 1/48th when you enable the crop-rec 2.6k preset.
If not you did something wrong , and that's why you have aliasing problem .
To get these sizes I had to increase the rolling shutter from 25.6 to 30.6 ms (milliseconds)

To recap the set up: canon menu - NTSC , 1080p30 (29.97fps)
In magic lantern: set shutter to 1/60th second or as close to it as possible (1/63th is good)
enable crop_rec and go to 5xzoom & it should say 23.976fps & 1/48th shutter .
I label this as user/cam setting error.

Side note, with this and with 3k build, when formating card in camera, it delete ml from card
Yes I know about this it's a bug that's very low priority right now , well get addressed in do course.

Yes,
i thought it was something about shutter speed...
Also, i remember once you said that all problems in 2.6k build (like red stripes) are related to improper shutter use....

I understand how shutter works, just did not think it will cause aliasing while i was shooting...

good to know

thanks

Any chance to test 48p soon?

3200x1143 @ 23.973fps on the 50D  :)
Almost got the vertical height regs figured out (not as simple as 5d2 unfortunately), still need to push the image down 52 pixels .
So , yea I can do at least 3200x1143 @ 24fps  :D
I do think I can push it to 3200x1330 @ 24fps , tried 3744x1143 , got to 22fps so 1300 should be doable at 24pfs if not a little more

Short out doors (my back yard) clip in my google drive , 3200x1143 @ 23.973fps
Exported with mlv app. , could have use some defringing in upper part of the tree branches near sky
but if I needed to defringe ,  I would just use Adobe A.E. with ACR , but still not a bad job.
The focus could have been better , it's just a quick test for increased vertical resolution

Ok the on the 50D the maximum resolution is 3200x1268 @ 23.98 fps but the image is not totally clean yet
still looking for the right vertical offset in cmos[4] . So at this point I do have clean image vertically at 1090 @ 24fps .

Some interesting information about the sensor on the 50D , it has 4.69µm(micro meter) pixel size
where the 5D2 pixel size is 6.41µm , no wonder the 50D is sharper but the 5D2 is more cinematic . 

Now I'll see if I can add the 50D to the existing crop_rec_4k_5d2  branch and have at least 1 preset (3744x1090 @ 23.98) for now
for the user to experiment with, but don't expected to see it for a few weeks or so . I need to get back on the 5d2 stuff .

Didn't what to double post , updated the 50D thread with my updates & video sample of UHD Test on youtube
https://www.magiclantern.fm/forum/index.php?topic=9852.msg216783#msg216783

I can confirm that the preview liveview regs work on the 50D same as the 5D2

Checking on Hi-Frame rate for 50D ,
In 3x3 maximum 1568x528 = 63.042fps thou it's a little unstable ,  60.058fps is stable .
in 5x Zoom(3xcrop_mode) 1920x760 = 48fps , I can't figure out yet how to put 3x3 in to 5x3
(720p mode) , adtg12[100c]0x2 -> 0x4 doesn't work like 5d2 , it may be a different reg
