some useful commands
Take care: o_O ~15 GB /o\ for one hour of video in DV (better than DVD format)- mencoder video.dv -ovc lavc -lavcopts vcodec=ffv1 -vf pp=ci,hqdn3d -oac pcm -o video.ffv1
- Unfortunately, ffmpeg2theora doesn't support denoising yet (though such a feature is listed in its TODO file). To denoise the source video, the best solution we've found so far is to the the denoise filters in mencoder:
- ffv1: lossless video compression codec from the FFmpeg project. This will create a big output file (similar to the size of the original DV video), but again, we do not want to degrade the source quality before using the Theora encoder. We do that same thing with the audio.
- ci: deinterlace filter (if needed).
- hqdn3d: high quality denoise3d filter.
- ffmpeg2theora -o video.ogg video.avi # or simply ffmpeg2theora video.avi which will replace automatically the extension with ogg
- mkvmerge -o video.mkv video.avi # use matroska container (package mkvtoolnix)
