I installed the July 15th build and found one issue: the mlv_play module cannot be enabled. Once I enable it and reboot the camera, I got some errors and all modules were disabled. Had to disable the mlv_play to have other modules working. I tried uninstalling the Magic Lantern on the CF card, re-formatting it and installing it back, still not working. When the module disabled, all other modules seem working fine.

Non-working mlv_play is a known issue. Use search field on upper right corner for more info.

@Reddeercity
I've testet your new Dual iso.mo and postproduction only works in MLV App.

- Can't export cDNG after force to dual iso in MLV App -> large Artefact in cDNG (in MLV App preview is correct)
- Export as cDNG without force to dual iso in MLV App -> lightromm plug/ CR2hdr  says "Doesn't look like interlaced ISO" / no Dual iso
- Open with  MLVFS -> "Doesn't look like interlaced ISO"

Maybe false Metadata?
-----------
Any new news to 4096x1770 half framerate?

Ok I'll check in to it , did you check MLVFS ? I use quick mount on Win7Pro looks ok also did you check MLVProducer ?

checking in dual iso metadata with ExifTool I get a warning from mlv producer with cdng's
Code: [Select]
Bad IFD1 directoryI can't see any dualiso metadata right now , either a problem with raw.c or dng.c  not writing correct metadata for dual iso , need to investigate further .
Thanks for the report .

Edit:MLVFS Web GUI (win7), set to dual iso 20bit etc. ....
from cmd when I refreshed web gui with dual iso setting 
Code: [Select]
Doesn't look like interlaced ISO
ISO pattern     : dBBd RGGB
White levels    : 10000 5000
Noise levels    : 8.00 8.00 8.00 8.00 (14-bit)

So yea there a problem , I'll need to debug this -- in the mean time your will have too force "dual iso" in mlv app. & mlv producer .

found some more problems , mlvfs web gui gave me the dual iso pattern and did not recognize the patterns
Code: [Select]
Doesn't look like interlaced ISO
ISO pattern     : ddBB RGGB
ISO pattern     : BBdd RGGB
ISO pattern     : dBBd RGGB
ISO pattern     : BddB RGGB
ISO pattern     : BBdd RGGB
these patterns alternate on each of the frames , need to look in the dual iso code and see what pattern are being used

So I shoot some footage using the 3K build and overall I am very impressed by the image quality and resolution. Only issue seems to be the aliasing and the very short recording time. I get 10~11 seconds with a Sandisk 120MB/s CF and 14 seconds with a Toshiba 150MB/s CF card.
I am very new to shooting videos but it feels really fun.
Thank you for your amazing work.

First , there no aliasing in 3x crop mode (5xZoom) it's 1:1 pixel , that why there a crop factor .
The aliasing in your video comes from your workflow (special the 8bit  Jpegs)
(From your Youtube post )
Quote
Workflow: MLV App -- CinemaDNG -- Lightroom for Coloring -- JPEGs -- Davinci Resolve 16 -- Final output
Plus I see it's also upscaled to 4k  :( , personal I think up scaling to 4k is a bad think , I never seen a good one yet .
It always introduces artifacts & aliasing issues

You go from RAW Cdng's (10bit ,Linear color space) to Jpeg (8bit , 4.2.2 , 16-235 color space) then grade it (coloring) in Light Room .
Why grade the 8bit Jpegs ? you are loosing all that data .
Best to grade the cdng's , you have Resolve so you can grade (color) the cdng right there , and if you don't like resolve
to grade your image you can use MLV App to color the raw cdng's .

The data rate for 2784x1160 23.976 fps is around 90MB/s & 5D2 CF Card bus speed is limited to around 75-80MB/s ( but this not a hard limit , working on overclock the bus speed)
So if you get around 15 second a footage that's about right , I have Lexar 1066x 64GB and what I get on average.
If you what longer record times use 4k Anamorphic preset or lower horizontal resolution in centered 3.5k crop to 2.5k etc. ...

Thank you so much for your advises. I use Lightroom because I am new to Davinci Resolve and don't know how to get the color grading done. The MLV App seems to render the images badly at least they don't look half as good when exported as DNG and opened in Lightroom so I don't really know how to grade in MLV App. Guess I have to learn how to grade Davinci Resolve now :D.

DNG is a raw format. None of the changes you make in it will take effect on Lightroom.

If you don't mind me asking... what were your export settings set to? Would be happy to get yourself squared up on MLV App to get the most out of your 5D2 while ur at it.

Please reply within MLV App to keep this thread on topic per @reddeercity. Thanks!

Ok back to Dual ISO patterns , I when back to the old March 2017 dual iso video module
and loaded it on  "magiclantern-10bit_12bit_raw_twk_crop_rec.2016Dec01.5D2212" and it works ok.
I did find the ISO pattern 
Code: [Select]
ISO pattern     : BBdd RGGB
The updated crop_rec dual video iso module has 4 different ISO patterns for crop_rec
Code: [Select]
Doesn't look like interlaced ISO
ISO pattern     : ddBB RGGB
ISO pattern     : BBdd RGGB
ISO pattern     : dBBd RGGB
ISO pattern     : BddB RGGB
I just need one ,
Code: [Select]
ISO pattern     : BBdd RGGBnot sure how this happen , basically I used waza57 dual video iso code and replace the non dual video iso module in the  5d2 4k crop_rec branch with the Video enabled dual iso .

But I find that MLV App still doesn't recognize it as dual iso ,
but MLVFS Web Gui does ! see below , it export as 20bit from 13.8 to 16.82EV
Code: [Select]
AMaZE interpolation ...
Edge-directed interpolation...
Smoothing alias map...
Final blending...
Noise level     : 8.00 (20-bit), ideally 8.00
Dynamic range   : 16.82 EV (cooked)
Semi-overexposed: 0.38%
Deep shadows    : 61.15%
Full-res reconstruction...
ISO overlap     : 4.7 EV (approx)
Half-res blending...
Building alias map...
Filtering alias map...
Amaze took 0.65 s
Edge-directed interpolation...
Smoothing alias map...
Final blending...
Noise level     : 8.00 (20-bit), ideally 8.00
Dynamic range   : 16.82 EV (cooked)
Semi-overexposed: 0.47%
Deep shadows    : 61.19%
Full-res reconstruction...
ISO overlap     : 4.7 EV (approx)
Half-res blending...
Building alias map...
Filtering alias map...
Smoothing alias map...
Final blending...
Noise level     : 8.00 (20-bit), ideally 8.00
Dynamic range   : 16.82 EV (cooked)
ISO pattern     : BBdd RGGB
White levels    : 16219 14819
Noise levels    : 8.00 8.00 8.00 8.00 (14-bit)
ISO difference  : 3.13 EV (875)
Black delta     : -4.94
Dynamic range   : 10.82 (+) 10.67 => 13.80 EV

So For now you can used the old 5D2212_Video_dual_iso.zip with magiclantern-10bit_12bit_raw_twk_crop_rec.2016Dec01.5D2212.zip together and you sure be able to use lightroom plug/ CR2hdr .
That build has only 10-12bit in crop_mode not 3x3(FHD) FYI

@Reddeercity. Sorry, could you please tell with simple words? As I understood, you did your work, and uploaded the source code for others?
