We used our Epic on its FIRST job today (a green screen studio shoot with a couple of talent talking on camera), and about 3 hours into the job, we pressed record and a blue semi-transparent vertical streak (about 1-1.5" thick and about 1" in from the right side of the screen) suddenly appeared on our monitors (the RED LCD, the smallHD assistant monitor, and our client monitor). The streak was also recorded to the clip. We tried a few different things as quickly as possible to try to solve the problem (rebooted the camera, restored the default settings, etc), but we couldn't afford the time, and ended up switching to an entirely different camera.

We were running v3.2.16 in terms of the camera build. I had our engineer go back to v3.0.7 to see if that changed anything, but it didn't really. The camera will now boot up without the problem, but after a couple minutes, the streak reappears.

The shoot lasted most of the day, so we didn't have any time to actually sit down and look at the problem. We had our engineer file a support request with RED - I don't think we've heard back yet - but I wanted to start a thread here to see if anyone else has experienced this problem? And/or had some suggestions? Any help anyone may have would be greatly appreciated!!

I had a verticle line issue with a redone an rob lohman at red helped by posting an old version of redcinex that would fix it in transcoding. Rob@ red.com

I haven't been able to replicate the issue, but earlier today I saw something similar show up.

I was messing around with high framerates and noise at 1k ~380fps and 12800. The camera had been powered down for the day, then when I powered back up and put a lens on I saw the lower 3/5 of the whole image had a blue tint to it (faint, but clear just the same - it was obvious) with a hard stop where the effect was gone on the top 2/5.

I adjusted the ISO back down to 800, then 640. Adjusted FPS back to 23.98 and shutter to 180. Rebooted. Pushed it back to those settings and back down and could not replicate the issue. First time I've seen it.

All seems well at present. Odd, though. Didn't roll on it or I'd post a screenshot.

Curious if you hear anything. Hope it works out for you guys!
