Hi all
I have a big problem and im asking for help. My raw videos looks very bad, they dont have a good quality and i dont know why.
You will see in the links below how the image has a bad grain/noise and its not sharp at all (focus was done perfectly). This happens outdoors and indoors.
https://youtu.be/oyqb29Cpv5U This video was shoot with 3.5 f 1/50 ISO 500 and 24mm
https://youtu.be/tMVbfaELaec this second video was shoot with f23 1/50s ISO100 and 24 mm
These are the settings i used for shoots:
Canon 5d Mark III
crop mode 3.5 1:1
resolution 3072x1308
2:35:1 aspect ratio
14-bit-lossless
build:magiclantern-crop_rec_4k.2017Jun19.5D3123
Komputerbay 64GB 1066x
canon 24-70 2.8f
LONg exp noise reduction off
hight iso speed nr off
highlight tone priority off
Please help, i will aprecciate so much. I cant work with magic lantern if i get this quality.
Thanks for your help
Without access to unprocessed footage and detailed description of your postprocessing workflow there will be no discussion. Include essential information (which Canon movie mode was used, ...), too.
And f/23? You are sure about that? I would prefer "sweet spot" f/8 for such tests.
I used mlv_dump.osx to get the dng files. Then imported dng files to after effects. There is no color correction its just what you see in the video. The dngs already looks bad even without make any color grading
Shoot in manual mode and using standard picture style
Watching the two clips on a desktop screen and I don't see any grain/noise ??? Could be the youtube compression hiding the noise...
Maybe you can share one DNG of both clips ?
Sharpness looks very normal to me, for an unedited clip.
That said, lenses are not at their sharpest with the aperture/diaphragm wide open or fully closed.
For sharpness it's best to stick around f8/f11
Ok I did it again this is what i have. Same settings as before. canon 5d Mark III
crop mode 3.5 1:1
resolution 3072x1308
2:35:1 aspect ratio
14-bit-lossless
build:magiclantern-crop_rec_4k.2017Jun19.5D3123
Komputerbay 64GB 1066x
canon 24-70 2.8f
LONg exp noise reduction off
hight iso speed nr off
highlight tone priority off
I get the dng using mlv_dump.osx.

https://youtu.be/nP-zXkJLYAE settings of this video: f11 1/50s ISO100 24mm
There is no color correction or similar in the videos. Any comments???

The first clip is a little noisy it's true but not too much, i see moirè and shaky footage probably due to the stabilizer on when on a tripod,
in the second clip the sharpness is bad due to high diffration at f23, if you try the same shoot at f11 you get better results.
after that i think a lot has been lost in youtube compression (it's a sad story but true, youtube kills videos). Try a diffrent compression ad upload to a better straming service (for quality) as vimeo.
i think you fighting against the aliasing filter in 5d3
The DNG's look good, really sharp and detailed 8)
The staircase is maybe a little bit underexposed, which could explain a little noise, because it's mostly shadow area's.
If the final video looks soft/unsharp, that could also be in your export settings in after effects, wrong export settings can kill fine detail.
Can you share your export settings ?
