But the predicted Vectors look ok? But... humen eyes

Is it possible to add/get an option or a mask, which show how good parts of the frames could be compensated by the filter?

Thanks, i will try this.

Despotting in general (not only with despot), for my optinion, is dangerous. So i would say, that when one don't know, that a filter can't compensate the frame good enough it is a catastrophe... But this is surely not the problem of your plugin. It make what it can...

Sorry.. this was a mistake by myself.

Thanks for your help
