Murray, Another thing to try is to NOT render directly from Cinelerra to your final output format. Instead try an intermediate format for both audio and video, then use ffmpeg or mencoder to encode those intermediate files into your final video.
For example, export your video as a YUV4MPEG stream with the following command, ffmpeg -f yuv4mpeg -i - -y -threads 2 -vcodec huffyuv -f matroska % and change the file extension to .mkv (extensions don't really matter, just a convenience). Beware, exporting as HUFFYUV creates LARGE files and you must specify framerate later to mencoder (with -ofps 30000/1001 for 29.97 frames per second), but it works like a charm and then you can choose different qualities for encoding the final video (ie one resolution/codec for youtube and another for DVD from same source). Export audio as a microsoft .wav and then convert to AAC, MP3, OGG, whatever. Mux the video and audio together into your final formats. Plenty of examples available online, just search for "mencoder mux video audio" or the like. I'd caveat the above works using recent SVN version of cinelerra, ffmpeg and mencoder. Its not too hard to install the latest SVN versions and the often increased compatibility and stability really pays off in the end. - Jim On Mon, 2009-02-16 at 18:04 +0100, bqz69 wrote: > Murray Strome wrote: > > Raffaella, > > > > Thank you for your reply.
