bright vertical line on material

[Peter Östlund]

It looks like a negative scratch and is totally vertical. Its position is 8% in from left. Two pixels wide bright. The sorrounding pixels left and right of the bright ones are slightly darker. I did not observe this when recording except once, when I then played back the sequence it looked fine. I assumed it was a temporary viewfinder problem. But now, when the job is done, the line is apparent in the following clips. First after changing drive, the line is gone. It is a mess and I now have to zoom in every clip, loosing composition. What has happened?

Which build are you on?

 

[Peter Östlund]

I am on build 17, the latest non beta.

 

[Brent Carter]

Peter, if you have not already, please contact tech support via www.red.com/support.

Can you upload a still?

 

[Valeriu Campan]

I had the same issue few times with build 18, when the camera was under heat stress. After a shutdown & about half hour cooling time, it worked OK.

 

[Peter Östlund]

This is what it looks like...

 

[Vico Martin]

Wouch!

what a pain!

 

[Paul Leeming]

Peter, maybe do a new black shading when the camera has been on for a while, to get a hot sensor balance. This is to prevent future problems (if it isn't a hardware fault). Definitely contact Red as per Brent's post. They probably have ways of fixing this at the R3D level to save your shots.

If that doesn't work however, and the shots are critical, there are software fixes available that can remove scratches etc from shots (designed for real film scratch removal).

I did a quick fix in Photoshop using dust and scratch removal on your JPG. Not perfect but that's from the compressed JPG file you provided. If you have the RAW 4K image sequence it should be far more accurate, and after removing the scratch and (most likely) downconverting to 1080p, for example, the shot will likely be fine:

Never give up hope!

Thanks Paul.
Maybe I got a tiny bit of hope back.
I will try Shake to see if I can do some kind of cloning.
Does anyone have a node for this already?

 

[Peter Östlund]

Update.
I have two solutions. One is to just zoom into the frame. The other is to lift the 6 pixel wide line and move the left part of the frame to the right to cover the gap using Shake. It works well in 75% of the cases when you don't sense the sharp shifting in pixel color along the vertical line.
I tried the scratch filter in Photoshop but it takes away small details all over and if you just apply it over the affected part it shows, especially with moving pictures. Maybe there is a way to fine tune this.

I also had the vertical line on the material shot after the change of drive, but a thinner one??

Anyway, after doing a black shading it seems to be fine but I am sending the camera to Red for checkout now. I don't want to experience this again.
The Red team are helping out just fine, as usual.

During camera testing today. We discovered a thin blue vertical line similar to Peter's in the center of our R3d files. It's not visible in live view during record only during playback. this issue does not appear on all clips, it's intermittent. We've contacted support@red.com

I had something similar happen way back.

Had the camera been running for a long period of time? That's when the issue would manifest itself.

I sent my unit back to RED for service and have never seen the problem again.

 

[fabio ferrantini]

I had same probem with build 18. I've done a black shading and it disappears but not definitly. It happened a couple of time during one day.
I hope there is a better solution, even because black shading took his time.

 

[Peter Östlund]

Our Camera is at the moment at Red. So far I have not been given an explanation to why it occurred but I am sure it will be clarified when the time has come.

 

[Peter Karlsson]

I've got the same problem six months ago.. Red fixed the problem, and the vertical bar has never re-appeared since. Black shading worked the first time it happened, but the second time it happened it never went away, so by then it was time to send it in.

 

[Peter Östlund]

Camera is back. No vertical line in sight.
Still wondering why it happened.
I am sure an explanation will come soon.

 

[Keegan@Netflix]

Hey Peter i just sent you a PM.

 

[fabiof]

so,
did you find any explanation yet?
How long does it takes (more or less) to send camera, fix and get back?
Any news about build 20?

 

[Peter Östlund]

A component on the board was bad. Further explanation will come. I seems to be a very rare problem. In and out took a little bit more than two weeks. I have not tried build 20, I don't use beta builds.
