No, I'm not ready to try it myself, yet. I just for now wonder if the MPEG-4/H.264 encoding earlier announced in Cinelerra only works for Quicktime or if it is a standard format that also may work with the upcoming Flash Player 9 standard support? By the way, if ffmpeg is a better tool for this job, it's ok for me. Here are my references: Cinelerra 2.0 released Experience the power of H.264 encoding and MPEG-4 audio encoding without having to pay for a Quicktime pro license. Import MPEG video directly. http://en.wikipedia.org/wiki/Cinelerra#History 5.1.1 Quicktime http://cvs.cinelerra.org/docs/split_manual_en/cinelerra_cv_manual_en_5.html#SEC70 The preferred encoding for Quicktime output is MPEG-4 Video and MPEG-4 Audio. This format is compatible in the commercial players for Windows, has good compression quality and good output quality. For better compression, use H-264 video. Unfortunately H-264 decoding is so slow it can not play very large frame sizes. Cinelerra supports two non-standard codecs: Dual MPEG-4 video and Dual H.264 video. These will not play in anything but Cinelerra and XMovie. They are designed for movies where the frames have been divided into two fields, each field displayed sequentially. The dual codecs interleave two video streams to improve efficiency without requiring major changes to the player. http://www.heroinewarrior.com/cinelerra3.php3 In probably the last move by multi billion dollar corporations to open up the best of the best technology to flat broke programmers, H.264 was standardized in Quicktime 7. Now Cinelerra can encode and decode video in razor sharp, ultra low bitrate H.264 with playback on Win and Mac commercial players and your favorite Linux players. This is one of the highest quality video codecs around, making HDTV distribution over the internet almost practical. --Terje _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
