Correct. I wanted to say, that I was in error with my former understanding. But if I have a interlaced encoded stream with interlaced content, I guess only both steps at same time ensure to get a progressive stream with good visual quality. If I have material, where only one of the steps have been done, to make up leeway the missing step should be a good idea. In my case, where the content seems more or less de-interlaced progressive, it should be good to remove the interlace encoding, but nothing more. This seems to be done automatically when transcoding the interlaced encoded vob stream to a mp4 stream with libx264, as the input stream is marked with "top first", but not the output stream. Please correct me if I'm wrong. -Ulf _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
