I didn't know if there might be a difference or not. Maybe there is a way to encode the black bars in the mpeg video stream besides just black pixels. I didn't know. Seems like its just black pixels. I thought before would be better, but wanted to make sure that the crop wouldn't mess us the fieldmatch, like a scale would for instance. Thanks for your advice. -Nick _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
