I really don't have much to say because it seems you guys may have seen before especially Alex.
I have been battling with my 5D mk III over six months now because of this crazy pinky distorted frames.
I can't shoot an interview but can shoot music videos at least cutting away those bad frames in post.
This only happen when using .MLV and not .RAW.
I really need to record in .MLV as i need sound.
I have read through this forum but can't get to find proper or simple solution as i am not a geek.
As a user, it's driving me nut and i hope it can be solved soon.
Please, forgive me if I am not posting this in the right forum or in the right manner but at least you understand the issue.
Kindly, tell me what to do to eliminate this forever

Also interested by an answer for my 5D3/113 (but I don't care about sound as I use external recorder)

Do you guys use Focus Peak or any some sort of while recording?

Which build was this occurring for you guys?

[Tao]

Yes I use it (Filter bias:balanced, imager buffer:low-res, threshold:1%, color:local focus). 5D Mark III, 1.1.3

I ran some tests just a few minutes ago and I had one pink frame over 10 10s MLV files when watching them on mlrawviewer.

Does it happen with the first raw too ? Can it be fixed in post ? Can't I have proper raw/mlv and focus peak at the same time ?

[DeafEyeJedi]

Try again with GD on and turn off Focus Peak -- IMO I think Magic Zoom works better and gives less frames corruption.

My gut feeling is that Focus Peak is pushing the GPU a bit thus may be causing these random pink frames?

Was this done with the latest nightly build?

[Tao]

I'll try again tomorrow without focus peak, but it's one of the most useful magic lantern tool especially when I shoot with shallow depths of fields...

I installed it 2 weeks ago from the official link (after downgrading from 1.2.3) so I don't know if it's the latest latest but it's one of the latests

The pink frames can be (easily) fixed in post ?

[DeafEyeJedi]

What exactly does your pink frames look like?

[Tao]

Pretty much like every pink frame

That looks like missing frames... I've seen these before and sometimes the missing spanning files would end up being on the SD card even tho you thought you recorded it all solely on the CF -- this has happened to me a few times in the past.

What were your exact settings in ML prior to recording? Was it in crop mode or no?

Have you checked for footage on the SD as of yet?

[Tao]

I first recorded with the SD (without knowing it), then it stopped and I selected the CF card in the camera menu, so it was recording fine from then and I ran the 10 10sec tests. There were located in the CF too. On the SD I only have some .CR2 I didn't imported yet and the .MLV I first recorded with the SD without knowing it but which stopped.

1920x1080, 24fps with 24.000fps override, MLV without sound, Global draw, zebras raw rub, focus peak, spotter on, histogram, raw video create directory, global row allowed, status when recording icon, files>4gb allowed...

No crop mode.

Also I have a Lexar 64GB 1066x (formated to exfat on mac)

[DeafEyeJedi]

Oh okay. I never record anything into SD, anyway. Just run ML on it (Unless it's h264). lol

Keep recording onto CF for best consistently results.

And you have exFAT recording enabled on within MLV settings, correct?

[Tao]

Yes it is enabled. So if it can't be fixed before/when recording, can I at least fix it after ? I noticed a MLFVS setting, is it related ? I'm going on a trip for one month next week and I kinda need to know if 5 or 10% of my footage will eventually go to trash or if I have a practical solution before/after recording to fix this.

[DeafEyeJedi]

Did you do a test run for without using Focus Peak and still same results?

[Tao]

I'll run some tests when I have my 5D3  but it is the only solution you see ?

Also thanks for your replies.

[Tao]

So I ran 4 series of tests, around 10 10 secondes each

-one without focus peak : no bad frame
-one with focus peak but 0,5%treshold instead of 1% : two bad frames (pink), one at the beginning
-one with focus peak but grayscale display : two or three bad frames, two weren't pink but were messed up anyway, one at the beginning IIRC
-one without focus peak : no bad frame

So I may be very unlucky or as you said this is a real issue with my current settings including focus peak. I coud forget the focus peak, but it's maybe the most useful tool imho. Maybe another/other tool(s) is/are pushing the GPU and creating bad frames ? Which would that be ? Was this a common issue on previous ML builds ? Therefore can it be fixed with some software or code manipulation ?

edit : further testing, I watched the files through MLrawviewer on mac, plain boring shots

-a 6min video with MLV and focus peaking, same settings as before : 4 bad frames across the video
-a 5min video with RAW (the first one) and focus peaking, same settings : no bad frames
-a 5 min video with MLV but without focus peaking, same settings : no bad frames
-a 3m30 video with RAW (the first one) and focus peaking, same settings : no bad frames
-a 3m30 video with MLV and focus peaking, same settings : no bad frames (lucky?)
-a 4m video with MLV but without focus peaking, same settings : no bad frames
-a 2m30 video with MLV but with focus peaking, same settings : 2 bad frames (pink), one in the early 20s, one the late 20s

so it's either MLV without focus peaking or RAW with focus peaking. I'll run some other tests tomorrow but it seems that MLV and focus peaking are not compatible if you want clean uncompressed footage.

[DeafEyeJedi]

Interesting facts you got there... if you want to upload a link to your ML settings folder and I can load it onto my 5D3 to see what you got turned on/off.
