What is this > flicker reduction and how can I get it with lav2yuv/mpeg2enc....? The "flicker reduction" only shows one field if you pause the stream. And does some other small things to make it look better. Take a look at the video without the flicker reduction. In the frame by frame mode (stop the playback and then go one frame forward or backward. This will show you how each frame lookes like. Maybe you have a 30000:1001 FPS (about 29,97FPS) video, and a 3:2 pulldown will produce something unnice. Try chnageing you comannd to something like that: lav2yuv *.avi | yuvdenoise -F | mpeg2enc -f 8 -P -I 0 -o video.m2v auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger for complex code.
