IS THIS A BLACK SHADING ISSUE? LINES IN FOOTAGE

[Matt White]

Thank you for responding. I reset the camera to default settings. Haven't seen the problem since I will keep an eye on it.

Thanks for the help bro. Yeah I knew this shot was underexposed it was late in the day and it was more or less a hail mary to get the shot. I appreciate your input

It looks exactly like CA to me.

I understand what you mean but what we see is like if the R&B pixel has been shifted from the G. Usually you see the CA on high contrast like your example. It wouldn't be a so sharp and precise shift on the R3D example.

How are you powering the camera?

Is the camera warm and up to temperature when you are getting this?

the only time I have seen this on epic is with a "cold" camera, meaning within the first ten minutes of booting the camera. The other time is when the battery power is running very low.

If its not these two factors then do a black shading after the camera has warmed yup foe about ten minutes and you should be good to go.

The black shading remaps the exposure of black levels at the cameras current settings, and from my experience and from digging through black shade posts from months ago, is that anything below 1/24th shutter speed should be recalibrated, and anything above that should be recalibrated.

Let's put this out there right now, black shading should be common practice for any change in environment (hot or cold) and settings that drastically change the framerate or exposure of the camera.

I'm not saying black shade before every change in a set up. For example, if I was to shoot a time-lapse with a long exposure and my shutter speed is 360º, then I'll do a black shade to compensate. When I want to change over to shoot 24fps at 180º shutter in the same environmental conditions, then I can go to the default black shade factory settings to compensate. I would only re-blackshade if I went from a hot environment to cold environment, vice versa, or if I decided to go from a timelapse situation to a HFR situation.

I've been using this practice ever since I received my R1 #813 and it's always yielded excellent results.

thanks for clearing that up, really wish RED would put out a PDF or general paper on the whole issue.
