Both encoded with ffmpeg at '-v > 6'. Unfortunately there is no -v6 to set video quality for ffmpeg :( According to documentation there is -crf to enable constant quality with libvpx. However testing it I'm not sure that this has any effect on bitrate. Looks like ffmpeg encodes with the target bitrate of 200 that's set by default. Note that constant quality audio encoding with -acodec libvorbis is possible using option -aq (maybe in range 0..100, 0 should be ok for nanonote's speakers). This is with latest ffmpeg from git, libvpx 0.9.6 and the ffmpeg patch: http://webm.googlecode.com/files/ffmpeg-HEAD-VP8_param_mapping-6.tar.gz Anyone made constant-quality encodes work?
