It might be easier to use Avisynth or Vapoursynth with MVTools directly:
* [MVTools from Avisynth wiki](http://avisynth.nl/index.php/MVTools)
* [MVTools technical page](http://avisynth.nl/index.php/MVTools)
Example to blur blocky area with occlusion mask
AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous
filter, etc
super = MSuper()
vectors = MAnalyse(super, isb = false)
compensation = MCompensate(super,vectors) # or use MFlow function here
# prepare blurred frame with some strong blur or deblock function:
blurred = compensation.DeBlock(quant=51) # Use DeBlock function here
badmask = MMask(vectors, kind = 2, ml=50)
overlay(compensation,blurred,mask=badmask) # or use faster MaskedMerge
function of MaskTools
This can be fed directly to mencoder or x264 compiled with avs (Avisynth
script) support. MPV can read directly from avs/vapoursynth so you can have a
"REPL" for video files with vapoursynth/avisynth.
And last, port to Vapoursynth:
