From time to time, people have asked about aspect ratios, 16:9 versus 4:3, and how picture sizes are set up and handled in Cinelerra.
I must admit that I have gotten it slightly wrong, telling people that stretching a 720x576 pixels image to 768x576 would yield "square pixels". It turns out that a 720x576 PAL image is NOT a perfectly 4:3-shaped image, as explained here: http://www.bbc.co.uk/commissioning/tvbranding/picturesize.shtml Some more details and links can be found in the page where I found the BBC link: http://lipas.uwasa.fi/~f76998/video/conversion/ -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
