AE is alredy off at record, something else must be changing expo. Have to find out what. ACR or camera.

Yes I can confirm the exposure shifting is an ACR issue. The recording is ok.
Still have to find a solution...  ;)

It's an ACR and  lightroom issue http://www.magiclantern.fm/forum/index.php?topic=5710.0

I read the thread. Ok. Everything indicates that it's a ACR problem. Yes it is. I ran some tests and if I don't move any slider in ACR everything works fine, no exposure shifting.
But what confuses me is that I'm using process 2010 and this still happens, so this isn't the solution, at least for me...

Don't use auto exposure for raw video. Use full manual mode and maybe auto ETTR (just don't keep it always on!)

I'm not using auto exposure for raw video, at least not intentionally, is there a separate auto exposure setting for raw and for h.264?. When I shoot h.264 this doesn't happen. It's full manual all the time.

I am noticing the same thing on the 600D. The exposure seems to change randomly, but generally when I point to a dark area the exposure adjust to even darker and when I point to a bright area the exposure makes it even brighter.

I have attached an example. Exposure changes start at 0:22.



Using CanonPreGdoff + Fileplay.zip for the 600D
960x544 24fps - canon mode 1080p

Yesterday everything was fine.
Today shooting 960x544... lots of magenta frames... corrupted files... card error had to format card and lost lots of footage...
I'm sad... :(

And the auto exposure thing is still there... is there a way I can "lock" it?

I've tested CanonPreGdoff + Fileplay.zip and of the 3 clips I shot, one was corrupted (first one) and the other two had NO magenta frames. I shot about 1400 frames and they were all OK! This is great!

Resolution 1024x448 24fps
Canon 1080p 24fps mode
Hacked mode off and everything else off

Shot my first music video with raw today  ;D

The shoot went amazingly smooth, nothing huge but there were lots of tight angles and low lighting shots. The build ran great, I got a few corrupt frames but they're almost always right at the beginning before the action starts.

Biggest concern is if the music will sync with the vids. Guess I'll find out soon.

Great! Post it when you're done!

Hacked mode turns off auto exposure and auto white balance.

Is there no other way? Not being able to see what we're shooting is a pain...

Set acr to process 2010 instead of 2012

It's already processing 2010...

Any more ideas?

Besides magenta frames there is other thing happening: exposure changes during recording. Seems the camera is auto exposing in an inverse way. When I shoot inside, where it's darker and then point to a window the camera adjusts the exposure to even brighter which is the opposite of a normal auto exposure.

Anyway I'd like to get rid of this auto exposure and have control over it. I've seen RAW videos on youtube with the same problem.

Any ideas?

Try this and you won't get more magenta frames, it worked for me:

Remove the card from camera
Turn the camera on with no card, leave it on
Insert the card
Turn camera off again and count to ten
Remove battery
Turn on the camera (without battery)
Shoot

Now you will get no more magenta frames

I am also noticing exposure changes on the footage (you can see an example on the video I just posted at 0:32 sec).
Exp override is on, shouldn't that take care of it?

I'm using the "Still Sprinkle Free" build. It works fine. Much less black dots on image.
Unfortunately magenta frames are still there, they seem to pop up in a pattern: 1 magenta....5 normal ... 1 magenta .... 5 normal... I don't know what that means. But afterall it's not that bad, I just have to "hunt" those magenta dng and delete them.

I've been shooting at 960x540. Take a look at my last test:

I'm still getting magenta frames (28 in 1117 on my last test) I'm using the 24 May nightly build and the "600D aspect lock" file.
Shooting in 1080p 24fps 960x408, sound disabled SRAW. Global draw off.

SanDisk Extreme 45 Mb/s 16Gb.

How can I get rid of the magenta frames? Any advice?

Robrock, go to the first post of this thread, to the link where you get TL 2.0. Download the top two on the page, paste the contents of "aspect lock" onto your card, then replace the existing raw_rec module with the new one (edmac kill, have to rename it to just raw_rec.mo).

If I use the raw_rec.mo edmac kill + res than I can only get about 67 frames no matter the resolution. If I use the raw_rec from the "aspect lock" then everything is fine.

Is this normal?

I'm checking these forums daily to see how things are developing. Congratulations, you're doing the "impossible"!
I'm so excited I even have trouble sleeping... :o

A few mintes ago I posted this question on the wrong thread...so here it goes:

Since shooting larger than 1120x434 RAW at 24fps is causing frame skipping I thought that if I decreased the frames per second then I could increase the resolution. With FPS override on 12fps I was expecting to be able to shoot at 1734x694 (or somewhere near that) but the result I get is dng's with pink noise. It wasn't just noise, it's possible to see parts of an image there but it's not usable.

I wonder if this is happening to others.

Ok. I see that I should have posted in the 600D thread.

Thank you

Right question but wrong place.  Did you adjust White Balance and Tint in ACR?

What's wrong with my question? It's related to the subject. Two or three posts back there's someone asking the same.
I'll ask again and try to explain it better:

Since shooting larger than 1120x434 RAW at 24fps is causing frame skipping I thought that if I decreased the frames per second then I could increase the resolution. With FPS override on 12fps I was expecting to be able to shoot at 1734x694 (or somewhere near that) but the result I get is dng's with pink noise. I said that it wasn't just noise, it's possible to see parts of an image there but it's not usable. It hasn't got to do with post.

I wonder if this is happening to others.
I thought this was a general question, if it isn't then I'm sorry I'll just shut up and move on... :)

I tried shooting at the highest resolution on the 600D  at 12 fps but all the frames came full of pink noise. They're not just noise, the image is there but it's totally ruined...

I haven't gotten pink frames since the first couple builds, even when recording for a few minutes straight.

Faulty card, perhaps?

Not the card. The previous card was slower and I already got pink frames. Yesterday I bought a new one (Sandisk extreme 45 mb/s 16Gb) and keep getting pink frames. Sometimes there are no pink frames at all even when shooting for a few minutes. I turn everyting off in ML menus and have SRAW enabled. I shoot in 1920 24p mode. Am I doing something wrong?

H.264 looks much better here to be honest. Did you up the CBR on this H.264 either?

RAW in low light has much more noise but at the same time is sharper so it's hard to tell which is best.
Denoising the RAW with neatvideo produced a very clean image without losing detail.
I'm sorry but what is CBR?

Quote from: 1% on May 20, 2013, 06:16:51 AM
That's a lot of pink frames. Really low light and high iso.

The ISO was 800, not that high. Pink frames seem to appear in some clips for no apparent reason. Sometimes I shoot something and there are zero pink frames. The next minute I shoot something with the exact same settings and BANG there are pink frames... no matter if it's ISO 100 or 800... but when they appear there seems to be a pattern, let's say there are 4 pink frames... then 5 seconds without pink frames, then more 3 pink frames, then another 5 seconds ok... and so on...

Hi

I made a simple test that I would like to share with you.
Not a fair test because the framing was different and I had to stretch the RAW footage a LOT to match the H.264...
