Fine. :)

Enterprise is also broadcast in Europe. And there it is not interlaced. So I would suggest what you have alreaddy found out. First correct the wrong interlacing and than run yuvkineco. You can also use yuvplay instead of pnmsplit to see what happens. One note: Scene changes can happen every field. 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:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
