The only _right_way_ is using ffmpeg library from cinelerra and producing the multiplexed files directly, without any pipes, middle-encoding or anything else. it's a week of work. not very hard actually (it is much much easier to do export support than import support for any choosen format). bye andraz _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
