Two more front-end filters to Frei0r effects - Posterize and Cartoon. Again there is some variation made using different parameters, but it isn’t a lot. The documentation is here:
The filters are here:
posterize.zip (1.9 KB)
cartoon.zip (2.0 KB)
When using these and the Baltan filter filter it is useful to increase the brightness to compensate for the filter’s decrease in brightness.
The MLT doculentation does not show a parameter, but the actual code does indeed have 2 parameters (width and height).
This is true, but the main problem is trying to get hold of the pixels of the underlying video clip, which I can’t find a way of doing. Dan gave me the code to do this for the GL-Transitions, but I don’t believe this data is exposed to the WebVfx interface to the Overlay HTML filter. If there is a way then I could probably do what you suggest.
Shotcut only implements 14 of the 85 or so Frei0r filters. However it does duplicate the functionality of some of the others. So there might still be quite a bit of life in them yet. The ones it uses are:
‘frei0r.alpha0ps’, ‘frei0r.bluescreen0r’, “frei0r.coloradj_RGB”, “frei0r.glow”, ‘frei0r.keyspillm0pup’, ‘frei0r.lenscorrection’, ‘frei0r.levels’, “frei0r.alphaspot”, “frei0r.pixeliz0r”, “frei0r.saturat0r”, ‘frei0r.select0r’, “frei0r.sharpness”. ‘frei0r.spillsupress’, ‘frei0r.premultiply’
