Can it process 10bit dual ISO removing focus pixels of eos-m?
I know, it's tricky.

Dual ISO make the same thing without ghosting, am I correct?
24bit hdr raw video? Is there something on the market capable of this?
It's seams a gymnastick thing, but... Why not!
Port it to eos-m please

Is it possible shoot in 10bit with dual-iso, and recreate 14bit in post?

Chroma smoothing over the entire image means some loss in contrast and "real" resolution, imho, and wrong results in dual iso.
For my test, I take a SP in "simple" mode of my room wall; in rawtherapee I've selected "none" for demosaicing filter, than exported as png; in Photoshop, simply selected single channels and made considerations by eyes.

Made some test exporting not-demosaicing picture taken with "simple" Silent Picture whit Eos M (using rawtherapee, and photoshop to view single color channel), and it seems that focus pixels involved are only the red ones, maybe some blue ones, but not green. I'm tryng to figure out if the influence on the blue ones is some sort of "ghost" due to my test condition.

Uhm, what about this:
in mlv a tag say the stream is interlaced
Raw2dng reed the tag, than separate fields and create new fake fields (gb for the rg, and viceversa) with value=0. This way we can have a normal debayer of rg fields of a time A, without interference by gb fields of the time B, am I right? (The other way around is to write a new specific debayer algorithme... But it seems pretty complicated!)
If I'm correct, than we have full temphoral resolution on Green channel to use in motion estimation that would be sufficent, i hope, to reconstruct well missing information.

well, in my case larger=useless

skipping one line takes problems in debayering? Audionut said it take resolution down to 1/4: if it's true, it is useless too.

I was thinking of debayer on pc and deinterlace after that: am I getting it wrong?

I don't unterstand: in a theoretical interlaced frame we have all red point (not half) of a time A, and all blue point of a time B. Is it not possible debayer it normaly, getting full red channel of time A (but no of time B), and full blue channel of time B (but no of time A)? Maybe have half green point for time A, and half green point of time B will get wrong output?

Untill some days ago, I thought any pixel had all 3 channels, I didn't know all debayer thing so... sorry for the stupid questions.

from my experiment, with deinterlacing two fields source you get quarter resolution too

I'm so near to get it! (the avisynth part )
I've sinthetized the new red channel for GB rows , but I'm getting a ghosts of near frames too. I'm sure it's just for my non-existent coding-skills.

Audionut, can you help me? This is my post on avisynth forum where I explain what I did and the problem.

On RG and GB: we could reconstruct blue channel for the first field by motion estimation interpolation of the second field, and viceversa for the red channel, using full temporal resolution green channel for good motion estimation. Yes, I think this is the way; "2 rows" deinterlace lose too much details.

I manage to get this frame to experiment, and I believe we have to find a way to manage the "RG and GB" thing  : 2 lines don't seems to work.


And after some test with "RG and GB", I know that if it's possible, I don't kow how to do

For now, I'm tryng to make an avisynth script to make "2 lines" interlaced" script (to deinterlace after). Sugestion?

I made the very same test of Audionut, so no point to upload it
I'm going to make some test with 2 lines ('couse I've not a clue to how to manage the  "RG and GB" thing)

SD camera has big limit in resolution for raw recording, and interlaced video can be a good work-around. 1080i can be converted in a good-enough 1080p with 3D deinterlacing magic from avisynth and his filter, and this tecnique can bring fake-4k raw to CF camera too!
It's not the real thing, but 3D deinterlacing can bring some amazing resoult. I'll definitely pay for such a feature!

based on my math EOS M, in crop mode and with 1472x626 resolution (2.35:1 and max resolution for continuous RAW recording), use a sensor area slightly larger than 1/2" format: every lens with the same (or larger) projection area is usable, but I can't verify.

Any news on Dual Iso for this little beast? Does it work now?
