Hi Marcin, are you sure you have activated the X11-xv display in cinelerra and that you have some sort of video acceleration? 1fps sounds very slow. I use a dual core AMD64 and have playback rates around 20fps on a ATI Radeon X300 using the open source driver. (for 1080i from Sony HDR FX-1). My friend and partner in this film project had more playback problems and achieved about 8 fps. So we indeed managed to get "the trick" to work. I even wrote a python script to exchange the refs in Session xml, but then it was not so urgent to apply all of this to the real project (and I myself am happy with my 20fps and didn't even bother to install the closed source drivers from ATI). My aproach was mainly as follows: - calculate a proxy version from each source MPEG (i.e. for each tape) - load it as resource into the cinelerra session as well, using the normal gui to load media. Thus cinelerra generates the necessay entries itself. If we drag a clip from the proxies to the video tracks, of course they will be much smaller (i.e. we let the track temporary buffer at 1440x1080) - use the python script to change *only the reference in the video track(s)* - and walk over the camera automation with the script and multiply each automation node with a scale factor. - re-open the modified XML in cinelerra and work with the proxies. - do the reverse prior to rendering. If you are interested I could provide the commands to calculate the proxy versions with ffmpeg and provide additional info. At the time we tested all of this, there were some (very minor) problems with the XML of the session files.

I am living in munich... -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFFLXo/ZbZrB6HelLIRApMkAJ0RerTT91kr405nJV7QysW8eqYllwCfQ/1o CFopV+ZiTRLJVLy8nZ/2sdY= =BaOu -----END PGP SIGNATURE----- _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
