Ok, RB (or anyone else). Right now I'm finishing a tool for CCE that uses an Ecl file (hehe - maybe you can guess...). However, I need to know the framerate of the video. I guess I can use the .ecl key 'frame_rate_idx' for that. I think for: NTSC film, 23.976 fps, frame_rate_idx=1 PAL movie, 25 fps, frame_rate_idx=3 NTSC video, 29.97 fps, frame_rate_idx=4 Can you confirm this, or fill in with information? Thanks.
