the green tint - was it using a player or after exporting with mlv_dump ?

can you upload one?

or dump a few frames from the .mlv using mlv_dump and the -f parameter (specify 2 or 3)

Tested again the 1.2.3 on my 5D3 and some of the MLV files had
a green tint and in addition some where very dark
(compared to other files with same EXPO.)
using rec raw it was ok.

im having same issue using mlv_rec recording at both modes 1x and 3x. Raw_rec i get the same error only in 3x mode. 1x is fine.

One thing i can say about MLV, the speed is going higherrrr....  :D i got about 108mb/s using mlv and crop mode.

did you zoom in while recording?
did you try WB using LR or similar?

The lens was zoomed out before recording.
The DNGs untouched.

Did you have memory hack on? Can you check if turning it off helps?

(this one changes video modes right before recording, so it may need a larger delay to settle)

I had the same issue, I wanted to add when I played the files back in camera they looked fine, however when viewed in MlRawViewer or converted they had the dark green color.

@a1ex
I have made some more clips with the memory hack on/off
and yes ,it is the source of the problem.
every time I turn it ON the green tint is there and stays on.

600D

I noticed this very green tint one time until now. I couldn´t reproduce this fault, so I didn´t report it. The dngs couldn´t be repaired by manual white balancing in postprocessing. But I could repair them in changing the blackpoint a bit, using exiftool. That´s just for info.

i also had memory hack ON all time... and i was getting the green tint on both modes

| raw_rec 1x green 3x green | mlv_rec 1x normal 3x green |

i tested both 5dmark 3 firmware's same results. Turning it OFF solved the problem.

Suggestion:  Have the Global Draw option in mlv_rec, set to on by default.  Based on the number of questions in the forums, asking why GD is off when recording.

Hi. Do you have fps override enabled when changing modes with memory hack on?

If so, I think the problem resembles the one I have on 6D. This issue is no related to recording:  LV is NOK also. The change of video modes (memory hack requires a set_lv_zoom to return from pause lv) with fps override (with overrides far from fps native) and shutter speed high (1/500 and beyond) is prone to sporadic LV problems.  The same thing if we change video mode with the loupe.

But on 6D it's worst than green tint, there are other artifacts.

Hello RAW world. I am newbie.
does this mlv record in 12 bits? or only converting after?
Now i am using bleeding edge 123, and due to slow card cant write fullhd, but if it 12bit i think it will be possible.
This module can be installed on bleedingedge or i need to reinstall with painful downgrade and other stuff?
Sorry for bad eng.

It records 14 bit. And please make some effort and spend at least couple of minutes searching the forum before posting, it is all there.

the next nightly will contain some fixes to file handling.
please try again if you had issues with corrupted files and 4GiB stopping.

@g3ggo,

Is it possible to transfer the Global draw switches Under RAW VIdeo Sub menu and Consolidate all global draw related options together with the Main Global Draw option in the Overlay tab?
It would be more user friendly if its just bundled together. Or is it because its part of the MLV module?

Hi Everyone. Does anyone know some good workflows for post processing the RAW material. (After you convert 'em to DNG). Thanks in advanced

I assume it's simply because the module is still experimental.

I'm having a hard time finding an explanation on how to merge MLV 2.0 files that span CF and SD cards.

I have spent time going thru the forums, looked at MLVMystic, mlv_dump etc. and cannot find the workflow. I have no problem converting MLV to RAW to DNG, but the spanned merge is eluding me.

For instance, how does one merge the three files that are generated for every spanned MLV:

M23-2258 2.MLV
M23-2258.M00
M23-2258.MLV

ps. this isn't the 4Gb file span issue, I use exFAT to address that

Never mind on the card merge. I used Hex Fiend to manually splice them together - the same technique used to merge >4Gb files.

It might be helpful to mention this workflow somewhere and if the card merge can be automated, that would be fantastic.  :)

you do not have to manually merge the MLV file chunks.
every tool has to support reading all of them.
always specify the .mlv file and they will read .m00, m01, m02 etc.

why do you have a "M23-2258 2.MLV" ?
this cannot be from the camera, you seem to have renamed the files?


when you record, the camera produces
M23-2258.MLV
M23-2258.M00
M23-2258.M01
M23-2258.M02
...

and for converting you open M23-2258.MLV in your favorite viewer/converter.
as simple as that. no need for hex editors and byte banging.
