Comment (by compn):

 I like your comparison videos. Very clear before and after.

 Your filter tries pretty hard on this clip from the incredibles 2, but I
 don't think theres anything that can be done for it.


 the only other thing i could think of is that the "next gen" version of
 this filter would remember which macroblocks are moving/changing colors at
 too fast of a pace, and then you could just freeze those ones while the
 (still moving, but not flashing) macroblocks are allowed to continue. Not
 even sure if its possible to do what I am describing though. It would also
 cause or look like tearing.

 is there a memory leak? seems to eat about 3gb+ ram here when using your
 filter vs no filters. could be a mingw bug or something else.

 but yes, if you have not already, please submit patch to ffmpeg-devel for
 discussions. that is the proper place for patch discussions. this bug
 tracker does not get as many eyeballs as the mailing list.
