-Known Issues:
-* The motion estimation is somewhat at the mercy of the input, if the input
-  frames are created purely based on spatial interpolation then for example
-  a thin black line or another random and not interpolateable pattern
-  will cause problems
-  Note: completly ignoring the "unavailable" lines during motion estimation
-  didnt look any better, so the most obvious solution would be to improve
-  tfields or penalize problematic motion vectors ...
-
-* If non iterative ME is used then snow currently ignores the OBMC window
-  and as a result sometimes creates artifacts
-
-* only past frames are used, we should ideally use future frames too, something
-  like filtering the whole movie in forward and then backward direction seems
-  like a interresting idea but the current filter framework is FAR from
-  supporting such things
-
-* combining the motion compensated image with the input image also isnt
-  as trivial as it seems, simple blindly taking even lines from one and
-  odd ones from the other doesnt work at all as ME/MC sometimes simple
-  has nothing in the previous frames which matches the current, the current
-  algo has been found by trial and error and almost certainly can be
-  improved ...
