Hi,

I am using MadMapper to drive two 64x64 led matrix via ArtNet. The content are black and white videos. Depending on the rotation of the fixture, some of the darker pixels start including colors (yellowish or violet hues, in other content its more red and green). I can also see that in the dmx monitor and the preview.
If I rotate the fixture this does not occur, but now the content is wrong. If I rotate the loopback device to make the content have to correct orientation, the pixels have colors again.

I created content that has exactly the 128x64 orientation and the color shift does not happen.
I tried the different filtering options and sizes: no change.

Any ideas?

Best,
Marten

This should not happen. Which version of MadMapper ?

It sounds like the issue might be related to how MadMapper processes color information when scaling or rotating content, paper iotry using a higher bit-depth video format or adjusting the color space settings in both MadMapper and your ArtNet device to see if it reduces the color shifts.
