Broken frames in RED ONE material?

[Mikko Suomalainen]

Hi

I've had my R1 MX since last december, and now first time I have a problem with it. A friend filmed some test shots in dark conditions, and when viewing the shots on computer, they show a "dead" grey bar on left bottom, but only on a few frames.
I haven't had any problems filming in daylight, but I haven't filmed in this dark conditions yet.

The material was filmed handheld on CF-cards, 4K 16:9, and I think ISO 1600.

I attached a picture, where you can see the grey bar.

Has anyone had same kind of problems, or do you have idea what it might be?

Only thing I can say is try a black shade, if that fails to fix the problem, RMA it.

I'll try that. But since it was only one frame in 2 shots out of ten, I don't think black shading will help. And this is a Battle Tested R1, so there's no warranty whatsoever.

Maybe I'll try to redo the scenario if I can get this happen again.

Any other suggestions?

I had a similar problem and I discovered it was the monitor or EVF cables. Try to change them and see if it solves.

Is the bar completely static when the camera moves, or does it change with a camera move or if the light from the left moves?

If it moves or changes, I'm betting it's a dim optical flare/reflection.

The bar only appears on one frame, so it is static. And it appeared in 3 clips out of 10, 1 frame in each, just randomly.

Can you set the ISO much higher in RCX-Pro and post a TIFF snapshot - it'll show up the issue more clearly.
