Looking great. I tried the clQuantizeLAB as an QCfx in VDMX but it's output is black.

Just taken a look at your composition in QC.

The patch for quantizing LAB values works fine with animations in RII patches and does work on video files I tested it with, although it is very easy to lose all information from input video files into a 'shared' colour space, especially if you are setting LAB to equal values.

See attached redraft.

Top and Bottom end values tend to result in either all white or black depending upon the predominant colour value average of the original source. This doesn't affect animations and RII image output in the same way as video input.

I especially like the way that the patch creates after imagery on moving objects.

N.B I had set the Billboard to Replace in the example, which is why the background colours up.
