"Screen Tear" issue
« on: February 01, 2015, 08:21:09 PM »
I was working on a small commercial for a marketing company local to me and I had this issue come up with one of the frames. This happens to be the take I intend to use in the final product and I was able to take some parts of the frame before and after to fix this very simple shot but, it does worry me if I were to be shooting something more complicated and wouldn't be able to do fix it and how much time I may spend trying to fix these kinds of issues in the future if it does continue.

Here is the frame in question.


I was shooting on a 5D3 1.2.3 build Aug 7, 2014. I edit on a Windows 8.1 in Adobe products. For this MLV I used raw2cdng 1.6.1, MLRawViewer 1.3.3 and MLV to DNG Batch Converter v1.9.2 all with the same issue. This leads me to believe that it is not with any of the software on the computer but ML on the camera. I did not see in the forums if anyone else had this issue and do not know if it was just a one in a million issue. I do not know what would be relevant but here are some information. I was using KB 64GB 1000x cards, the card was warmed up and I shot a few minutes before hand, fix black level was on, Use SRM job memory was on, Extra Hacks was on, Reserve card space was on. There was no warning in camera during or after recording this take. It was not split up into multiple files.

If you look closely at the image, it appears that the tear, or what ever the proper name is, is shifted over to the right and over exposed with a pink tint and green in the whites. Has anyone experienced this? Is it a know issue? Is there a fix? If anyone needs any additional information from me to diagnose it, I am sure I can get it to you.

I had this when shooting raw on my 600D. However it never happened on 5D Mark III.
Yes, as Paul said, it feels its more related to hardware.

Thanks for the input. I don't know if it is related but, since then I have downgraded from 5D3 1.2.3 to 1.1.3 and the issue seems to have gone away.

I am on 113 and this is one in about every 100k Frames on MLV.. Not a specific number ofcourse, but I do see this "screen tear" now and then, usually only the thickness of about 10-20 frames though.

"Screen tear" is something btw, this is what I would call a broken frame. Screen tear is when upper part and lower part off a screen are not in sync. Sometimes several parts of a screen might be out of sync. Like watching mlv's play in mlv_play module. just FYI.
once you go raw you never go back

Good to know that 113 still annihilates 123 and bleeding like crazy... Love it!
