Hello All,
I seek a decomb filter that operates on H/2 number of line pairs: lines i & i+1 (where i=0..H/2-1),
by aligning edges in the two lines at x = delta-x(edge)/2 (i.e. the median). The ideal filter would
differentiate overall motion due to panning versus local motion due to local object
I'm also planning to use the `-progress` option, to display a progress
bar to the uploader client.

how can i convert a H.264 High L5.0 .mov video to a H.264 High L5.1 or L4.0
