hey all....ive been trying to do some .m2v conversion with the qt 6 pro mpeg4 codec. im doing chapter 15 from the fast and the furious, and my settings are: size: current, video track: improved, bitrate 800 kps, frame rate: 23.98, keyframes 240. im still getting an output that is lower quality than when i use ffmpegx 0.0.2. anyone know why this is???
