Just looking at the video on its own, it's somewhat hard to tell. But if you're scrubbing through different shots, you can definitely see it. I made a gif comparing two identical shots, and you can clears see large dark yellow lines in the video: http://gifmaker.cc/PlayGIFAnimation.php?folder=20170119148rfTBjPEQ0fZEqE0dSjwXB&file=output_ZpFhpX.gif

Any ideas what could be causing this? I've seen this while shooting on 24p cinema as well as 720p@60fps at several different ISO and shutter speed values.

I am the proud owner of the D7100 and I don't know if you were desperate as I was while watching first movie tests recorded with this camera. You guess it: Horizontal noise, or bending if you prefer.

Of course I tried different picture styles for D7000 and they looked terrible because the sensor is not the same. The D7000's chip doesn't have same banding issues as Toshiba's on D7100.

So, I decided to experiment by myself with PictureControlUtility and create my own style that can satisfy my needs while shooting the video with my awesome D7100. My picture style can be found here:

It's based on Neutral pic style. With this look I can go up to ISO 4000 and to enjoy image quality, where grain looks more film like and less digital. It has more contrast than usual Neutral style, BUT less horizontal noise, and in my case I can recover dark parts very easily in DaVinci Resolve.

Anyway, I open this topic because I would like, as many others I guess, to see from other videographers their custom D7100 Picture style(s), to share it here with the other users as an alternative for shooting with less 'bending' headache :)

Cheers!
