Hello, I was wondering: when a film is recorded by a camera in 25 fps interlaced, actually every other line is updated 50 times per second. So, since I want to scale the film by 0.5 anyway, I could gain 50 fps on the way. Gaining fps is valuable to me, as I am going to play the film in slow motion. So my question is, how can this be done using mplayer/mencoder? Cheers Kristo
