Yes, I've often wondered that myself :-) The manual is silent on this subject. However a possible interpretation is that the bracketed numbers indicate defaults. Thus 720x480 is a 4x3 aspect ratio but the actual frame size is different so the video will be distorted. Transcode can crop, pad or rescale it to the correct ratio if required. poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
