AFAIK you cannot use AVCHD directly in cinelerra, you have to transcode it first to a not-too-much-destructive format. I use to convert my AVCHD footage (1080/50i like yours) to DNxHD with ffmpeg. DNxHD has been developed by Avid for video editing purposes and is supported by ffmpeg and cinelerra. It has several modes depending on the resolution (1080 or 720), frame rate and bitrate. Here's some doc from Avid : http://www.avid.fr/resources/whitepapers/dnxhd.pdf (these modes are listed p. 9) Sample commands to transcode your footage to DNxHD before editing : DNxHD 185 : ffmpeg -i <footage> -s 1920x1080 -r 25 -b 185000k -vcodec dnxhd -an <output.mov> DNxHD 90 : ffmpeg -i <footage> -s 1280x720 -r 25 -b 90000k -vcodec dnxhd -an <output.mov> You can even render your projet or intermediate file to DNxHD with cinelerra by using YUV4MPEG. Hope that helps. Julien _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
