I have a 30fps movie here that I would like to resample to 60fps, while
keeping the motion real-time. This will require twice as many frames as
I realise that I only have a limited number of frames to work with (half
as many as I need), but I also know that MPEG has motion detection built
in. But that's about all I know.
Is it possible to use mplayers motion estimation to generate
intermediate frames for this kind of business, or am I being terribly naive?
mencoder test30fps.avi -ovc lavc -lavcopts
vcodec=mpeg4:vhq:vbitrate=4000 -oac copy -ofps 60 -o test60fps.avi
but of course every second frame was reported as a duplicate frame.
I know that algorithms exist to generate intermediate frames (hell, my
100Hz telly at home does it in realtime), but are they similar to what
