I ended up upgrading my system from Windows 7 to Windows 8.1 (because of the better power management—Win7 drew 60W more in idle due to my hardware configuration), and ever since installing the PotPlayer+LAVFilters+MadVR package and SVP again, the banding problem has disappeared. Even in the anime scene I posted screenshots of, everything is fine now.

Doing that causes the picture to be dark and there is some banding, yes, but it’s hardly visible. Not quite as in-your-face as with SVP. http://i.imgur.com/FBDCpLq.png

Setting ffdshow video decoder (raw) output to PO10 did not improve anything for me.

I find it hard to find the exact same frames in SVP and non-SVP mode because of the interpolation frames in-between. The difference is consistent, though. The banding in SVP is always apparent, and without SVP it’s never there.
This is the closest I managed to get:

Also, I don’t think ffdshow is at fault here. When I set SVP frame interpolation mode to Off and re-open the video, without changing anything else, the banding is gone.

These are not the exact same frames, yes. Because SVP is inactive initially when skipping to a bookmarked timestamp, it was hard for me to capture a frame both with SVP active and without. But I can confidently say after testing several times that the color banding is always apparent when SVP is active, and not there when SVP is off. (For example when opening another instance of PotPlayer and opening the same file, or setting Quick Settings → frame interpolation mode to Off.)

Also, where would you get 4:4:4 content from? I’d love it if it was standard, but unfortunately almost everything is in 4:2:0 even.

Video and monitor are 8bit, so I suppose even if I had 10bit video the monitor would display it as 8bit?

But anyway, I have all my settings like you instructed (GPU-acceleration / OpenCL checked, random dithering, output formats only NV12 and YV12) and the banding is still there as soon as SVP activates.

First, thanks for your awesome software! It’s really great.

For some reason, I recently experience banding whenever SVP is active. My configuration is PotPlayer+LAVFilters+MadVR+SVP. Everything except SVP is downloaded from imouto.my/redirect/32.

I did not notice this banding problem before; it happened without me changing something in the SVP settings. I do use other programs that use Avisynth, though (AvsPmod and MeGUI), maybe those have something to do with it?

Anyway, when watching 8-bit anime, this is how it looks like when starting the file (during the delay before SVP activates):

And this is after SVP activates:

MadVR info display (Ctrl+J) always says 8-bit NV12.

Can anybody tell me what I have to do to get rid of the banding?
