Cinelerra doesn't automatically set up an aspect ratio for the project. Usually, when you're going to do a project, which is mostly based on anamorphotic footage, you set up the correct aspect ratio for the whole project. If you use a non-standard aspect ratio, this has impact on other areas like titles, included stills and included non-anamorphotic footage (ideally, a video editor should adjust those automatically, but Cinelrra doesn't you have to care yourself for that). Probably that's the reasoning behind why Cinelerra doesn't do this setting for you. > Finally, this week I resolve the problem and now the Compositor window show > 1024x576 complete image: - first, resize vdeo track to complete image size > 1024x576 - second, use Scale effect and setting x to 1.7778. Sure, this works, but it causes additional processing and might even degrade your output quality. Thus, you should use this approach only for the minority of your footage, i.e. when you want to insert one anamorphotic clip into a lot of non-anamorphotic footage. If most of your footage is anamorphotic, you should instead define your project accordingly, i.e. set the correct aspect ratio in Settings>Format If you do so, the viewer and the compositor will stretch your footage on display, but no processing happens on the rendered output. hope that helps Hermann Vosseler -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkq+H+oACgkQZbZrB6HelLLjagCgrEi8TU2niAmJlse1NEa241ae P0EAoLYbUT9jvbxpn32JBSk7fUjiX1kx =VUGc -----END PGP SIGNATURE----- _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
