I just made screenshots using the player "Xine". The black in the re-encoded version is indeed #000, and it looks virtually the same as the original. I really don't understand this. Even if there is something wrong with display brightness of mplayer, it shouldn't display both movies with identical brightness. Check these frames (saved with low quality jpg, but that doesn't matter now. Also, don't know if attachments are allowed, so I hosted them externally): This is a screenshot from the original movie: http://www.halfgaar.net/posts/2008-04/screenshot-from-original-movie This is a frame rendered by Cinellera when I load the movie from above and render without any modification, to jpglist. http://www.halfgaar.net/posts/2008-04/frame-rendered-by-cinelerra And when I reencode the overly bright images with mencoder, this is is the result (a screenshot): http://www.halfgaar.net/posts/2008-04/rendered-by-cinelerra-and-encoded-to-xvid-then-screenshot The only thing I can think of, is that there is some kind of gamma info stored in the jpg, but I don't know if that's possible, or how to check it. _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
