Yesterday I did some shooting with latest build on 5dmk3
1920x800 @ 60FPS

https://drive.google.com/open?id=0B-d8ARtc7xwWQU9kVkktTW9NMEk

I cannot decompress some MLVs, here is a sample.

Use your wizardry
Thanks in advance

* 4096x1440 @ 25p (1:1 crop)

Is anyone could find ершы mode? I've check all modes and just can't find it. Is it exist?

Try changing Canon Video System to PAL/NTSC
or try changing 1080/720 and see how it affects your vertical size.

Magic Lantern updates may generate incompatibilities with existing supporting tools. This is natural.
Developers of ML and ML tools are not gathered under the same roof and develop in synchronization.

ML developers specified in the first page that the only way to get DNG files is using mlv_dump
that is available in the download / experiments page.
Insisting to use last years tools, or older, together with today's ML build, is a waste of time.

I confirm the bug with the black screen when 1920x800 @ 60FPS
It takes some patience and some assistance to recover Liveview back.
I press Canon Menu a couple of times and then ML button.

Awesome !!!
It heals the problem.
I tried it on other corrupted mlv and it works.
Thanks for your wizardry 

you could also apply this (totally untested) patch - maybe it was only one frame that was faulty.

Any chance to review the corrupted mlv file I placed on my Google Drive ?
Thanks in advance

I have no clue how to modify mlv_dump.

Here is one of the files

@ dmilligan

The data is corrupted.
There is no way to retrieve anything ?

I have 16 MLV files that fail to decompress. They almost 1GB average, each.
I was shooting with 5d mk3, 1.1.3. 1920x1080/50/60 2.35:1, 14bit lossless.
I use latest mlv_dump.
I get a message

LJ92 : failed (-1)

The mlv files were random among 70 files and their order do not satisfy any logic.
The last 10 shots were faulty. I assume the problem rested there.

I can upload a mlv file on my GoogleDrive for public access.
Any clue ?
Thanks in advance

Its a harmless compromise

@Savely

In the directory where MLV_Dump.exe lies, make a .bat file and put this in it:

@echo off
for %%a in ( %* ) do ( md "%%~na" 2>nul )&( "mlv_dump.exe" -o %%~na\%%~na_ --dng %%~na.MLV )


Drag and Drop the MLV files onto the .bat file.
It will generate Folders with the frames

@ DLM

Yes!
When I use Handbrake to convert some videos to MP4, Handbrake detects 2 pixels wide column and crops it.
e.g if I shoot at 3072, it shows 3070, 2 pixels offset

Yes, I did some continuous flawless 3K shots. Incredibly awesome!
The 1st of April is ML special day.
I hope MLV_Sound returns some time and works in hand with video.

Please make frame names to contain original name of MLV, not "frame"
It makes more sense if you shoot 30 videos and you post process them and you need to find the original name or think of a new one

Read the little help text at the bottom of your screen.

As long as you use the Experimental Build, you have to use mlv_dump. Its located in the same page to download.
From the Camera-Icon menu / Crop / 1920 50/60 3x3
You have three options.

If you select Canon's 1920x1080 25FPS, you get 1920x1080 25FPS.
If you select Canon's 1280x720, you get 1920x960 50FPS.
If you select Canon's Video System as NTSC instead of PAL, you get 1920x800 60FPS.

mlv_dump is your friend

On 12 April 2017 I took several shots.
I was recording with that days latest build, 1920x800 60FPS 14bit lossless with 5dmk3.
On some of the shots I took, on the top of the frame there is a horizontal sharp edge that flickers, about 100 pixels away from top

(I am not aware if this is fixed already)

I was away for some time. Trying latest build.
Way much solid!
The exclusions of many combinations makes things more targeted.
Thank you for the hard work and constructive development

Thanks a1ex, too many things to remember/learn
Its hard to carry a manual with you

It takes 5 minutes to dial proper number.
I would prefer a number to subtract rather than setting absolute vertical resolution.
Its faster and practical.

Having involved into beta testing of 3d software in the past, in my humble experience, its good to keep an order in information coming, sort them, classify them, confirm symptoms etc. Its very hard

Admiration for many reasons
For revolutionary development of out of this world features , for so many cameras
Baby sitting the forums with so many users of so many experiences and variation of needs and knowledge
I surrender, I could not do that

Unfortunately I erased the videos.
But ... how do we attach an image on the post ?
Sorry for my ignorance ?

Actually that post about compression needed to be in two parts
a) Why do I get these boxy big pixels compression-like in out of focus areas
b) Is 14bit and 14bit lossless visually identical

The question b) is answered already.
The question a), I guess was due to a different reason other than the bit depth

But I understand a1ex words about bit depth. Great explanation
