@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
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.
