If you are looking for a piece of effect that gives a crystallization-look to video, one is BCC Mosaic. BCC Mosaic is one of the filters included in Boris FX’s Boris Continuum Complete.

You can control the degree of crystallization separately along the X and Y axes. And changing ‘Apply Mode,’ you can produce a more created result.
