Ok, this was easy enough. The following tool will extract the video data out of an MXF Project, and dump those into a file raw.dv. It does not do anything to the audio. http://propirate.net/oracle/zipfiles/mxf-dv-dump.tar.gz If you use the DVCPRO50 codec, the file should work with a sufficiently recent version of ffmpeg. If you manage to apply the patch that I linked in this thread, you should even be able to work with DVCPRO HD footage in ffmpeg, altough I haven't tried it. The included README says: -----8<-------------------------- This is a trivial utility that extracts the raw dv data from P2 MXF Cards. it is very simple and does not do many sanity checks, use at your own risk. you call the program with 2 arguments: 1: The /please/use/your/path/CONTENT/CLIP/blabla.XML argument specifies the xml file of the video you want to extract 2: the second argument gives the path to the P2 Project: /please/use/your/path/CONTENT/ The utility will create a file called "raw.dv" in the current folder. Thats all. Cheers -Richard _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
