Decimate Gurus I need your help
i have an interesting 59.94 progressive HDTV stream
the problem is there is no static pattern for dupe frames. Normally i would use selecteven() or selectodd() to get down to 29.97 then a Decimate(5) to get to 23.976 and all would be good to go. But this stream is wacko. There is a single frame randomly placed in it every 10 to 40 frames with NO dupe frame. Now what is more wacko still is this single frame does not happen the whole way through. minutes can go by with no single non duped frame then all of the sudden they start up again. if i use selecteven() or selectodd() then 50% of these are cut and i get a jump which of course looks bad. if i use decimate (2) then the 2 frames will NEVER be dupes since the one is always the only one so 50% of the time it gets deleted there too since it is randomly placed. the basic pattern normally is AAABBCCCDD the whole way but this stream is AAABCC or AAABCCC or AABCCC (it randomly changes as it goes) suggestions? |
