BTW - once you (or anyone else) are ready to run the proof of concept code (digic6-dumper branch) on your camera, I can enable the boot flag.
Is that digic6-dumper branch not safe to run on camera or what?
If my camera won't turn into a brick maybe I'll give it a shot

@Karim, are you sure you didn't accidentally enabled other options in MLVapp, like the option to fix 'pattern noise', right below dual-iso settings in MLVapp ?
Pattern noise option really messes up my dual iso video.
I tried to turn them on / off.. but now I got stable dual iso results on v:1.2 of MLVapp
thanks for your help dude  :D

So made a crop_rec preset with this 1x3 mode for 6d, 25fps (for use in non zoom mode, no need to go to 5x zoom):

Here stupid questions comes  :D
should I set canon menu video to 1080p or 720p?
Am I able to use this for 16:9 final result video?

when I set ratio to 2:1 1832x912 and 1824x912 is maximum resolution I could choose is that normal?
on RAW video option it says "1824x912  3.00x" does that mean I got a 3x crop factor? what if I want to use that as 1.0x (entire full frame)?

I tried to shoot a test but I got some trouble judging stretching after trying to get it natural unstretched looking.

excuse my low IQ it's all very confusing  ::)
can't wait to test your high fps preset  ;)

Yes 3x3 and 1x3 is about line skipping in sensor.

Doing Dual ISO after the Binning process it will show a lot of artifacts and aliasing here will come the big benefit of 1x3 mode applying Dual ISO in full sensor height (using more pixels for dual iso) then stretching it down to the correct aspect ratio. In this way the details will be restored with less aliasing and less noise too.

In MLVApp there are no problems when using Dual ISO with

Nice to meet you too Bilal  :D

I was confused about 1x3 and 3x3 but I think I started to catch it right

I tried MLVapp v1.2 and it gave me stable dual iso results, not like the crappy test I made on v1.0
but still, I got minor artifacts like red and white dots it appears like for 1 frame long.

I shooted a 10-sec video and I spotted like 7 or 10 dots in total that appear and disappear instantly
I tried to mess with some setting in mlv app dots almost gone like 1 or 2 dots

It was 14bit lossless 30fps out of 6d
I used:
in details panel
Denoise window 3x3
strength: 35

export settings
ffmpeg kostya
resize 1920x1080 (was 1824x1026)
smooth aliasing tried off, 1 pass , 3 pass
seems like 3 pass was softest image but no small dots also less aliasing (straight lines still looks like a zigzag)

Sorry if it's not even related to your 700d research I just wanna to share with you my experience to know if its common or im having trouble in my raw mlv workflow, I feel that I can't rely on it in serious projects yet :(

Shot on 700D:
1504x640 in 3x3 and 1504x1920 in 1x3 downsized to 1504x640 (@ 23.976FPS 2.35:1).
I can shoot up to 1736x736 (1736x2214 in 1x3) 2.35:1 but this requires 80mb/s write speed in 1x3 Binning mode

The problems:
-Very stretched LiveView

I just checked your video the dynamic range is so impressive and aliasing is almost gone!

I want to clarify some confusing things
what is 3x3 and 1x3 exactly and what's the difference?
I know about the line skipping thing the sensor does to fit a video is that something related?

why you downsize your videos? after all I cant notice visual difference in the video but it's more technical of course

I own a 6D I think your options doesn't available for my crop_rec but I want to understand how things goes on
also dual iso +mlvapp work with 14 bit only any lower Iget a final glitchy video does it tha same on 700D?

Had the same error, fixed like described in the post you quoted.
Thry this file and replace it with the file already on your SD card.

Thanks for your help dude  :D
well, I tried it and it worked on camera but when I export it from mlvapp v1.0 with dual iso option on it gives me a moving stripes video like how live view see when dual iso is on and random green frames I don't know what's wrong

*update: It works perfectly with14-bit & 14bit lossless
if I choose 12 or 10 bits or lossless ones they make the same issue

btw I'm impressed for your high fps research you're going to make something revolutionary!

Guys I want to test 12 bit loseless comp along with dual iso on my 6D but when I turn on it gives me ISOless PH err(3)
I tried to take a working dual iso module from the latest nightly build but when I activate it says old api version 6 , 7 expected
I read this post below but I dont know how to edit .mo file I opened it on notepad++ and it was encrypted
and yes I have no idea about coding  ::)

Tried this with my 6D which I bought in Japan. Frame CMOS I changed to 40e6190 and photo CMOS I changed to 404e4e06. Still ISOless PH 3.  Only Magic-Lantern-4k crop mode has the issue. Not the Nightly build.

EDIT: It works! It was only me who didn't read everything. New values in CMOS 3 and not CMOS 0:

It will be useful even if it can help just 10% I hope it can be added
use the little orange lamp that blink while timer count, I have no idea about coding but you give a command to the lamp to fire up while auto focusing, this feature is already available in some nikon's so I think it's easy to make, sorry for the bad English i hope you understand me well  :)
