Before Reddeer kills you,
I don't think there is a black bar in the 1880 Build. Its very old build, before unified.
:P
Yes in the old core code with raw_rec module before mlv_rec in 2014 ->2013

If you like to try it on your 5D2 ML-build_Oct24_orginal_raw.zip
You have to delete all the old file from new builds except the "CROPMKS" folder (but it will work without it)
all you need for modules is  RAW_REC.MO & 5D2_212.SYM plus the AUTOEXEC.BIN in the root of the card .
so you have just 14bit , & 1880 or it can be switched off for just 1872 & 3x crop_mode has 2152 .

So to catch up, ML is “unified” now? In layman’s terms, what does that mean exactly (for us non-coders?)

Reddeercity, is 1872px not available because the “unified” code requires 32px increments? Thus forcing us at a max 3x3 binned resolution of 1856?

Maybe the answer to the previous question will answer this one: Any way to get 1872px in the 5D2 nightly build?

(Thanks for answering these questions for us “late-adopters” of ML)

“unified” as the word mean "Join together"
so the best parts of different development branches (including source code from the old core)
merged into the "unified" Source code which the nightly builds are based on .
Exception are things like "Crop_Rec" , "Dual_ISO Video" , etc. .... there are developer own branches
which is based on the "unified" source code with developer own modifications to the code .

Once the developer's code is stable & proven to work correctly they can 
submitted there code to the Admin (aka a1ex) to be joined with the "unified" source code (which the nightly are base on)
This the goal of all developer/coder in the end . 

Reddeercity, is 1872px not available because the “unified” code requires 32px increments? Thus forcing us at a max 3x3 binned resolution of 1856?
Short answer , Yes

Any way to get 1872px in the 5D2 nightly build?
I do believe that the mlv_lite module has the work around to get 1880 but at a cost .
There no audio support on d4/5d2 , you can't kill the overlays(global draw) where recording
which reduces the record time by at least 30+% .
mlv_lite is mainly mean for compressed raw ( which has has reduce data rate) which the 5d2 does not (Yet)
thou it still work fine

But sometime down the road I could possibly add support for 1880(3x3) in my "Crop_Rec" branch    for mlv_rec module that has audio support
That would be more then likely way down on my priority list .

Another question. Lol. Sorry!

Does it matter what movie setting is set in normal canon menus for MLV recording if I always use FPS Override?

I'm deeply sorry, but who could, please, be so kind to tell me where I could find all current RAW capabilities of 5D Mk II?

@reddeercity, thanks so much!

Just some thoughts here, to help me wrap my head around this:

As of now, 1856px (3x3) crops the field of view 1.01x (IE: 50mm equivalent is 50.5mm.) If we could get 1872, we could get a full field of view in 3x3 mode. But would require a resolution increment of 16px. What are the caveats of a smaller resolution increment?

Thank you!! Happy to help in any way needed!

I see a lot of users posting about 3x3 and 1x3 mode.
I'm a bit confused as to what this is, is there an explanation of what it is anywhere?

Sorry if this is a stupid question.
