hi andy!
sorry for late reply!
thanx a lot for the bitrate hint. increased it to 1500.
takes lots of space, but the quality is great now!

Hi Roland
Have a look at the latest version of indytube released for plumi 0.2.x
http://plumi.org/browser/indytube/tags/plumi-0.2.3-rc3
in particular the latest example conf
http://plumi.org/browser/indytube/tags/plumi-0.2.3-rc3/indytube.conf
the mencoder options in particular, are:
# for newer versions of MEncoder, we dont need the "lavfopts" line
above, plus we add in a higher bitrate, and a sync option
MENCODER_OPTIONS=-really-quiet -of lavf -oac mp3lame -lameopts
abr:br=64
-ovc lavc -lavcopts
vcodec=flv:keyint=25:vbitrate=260:mbd=2:mv0:trell:v4mv:cbp:last_pred=3
-vf harddup,expand=:::::4/3,scale=320:240 -srate 22050 -ofps 25 -mc
0/10

Notice that in the example indytube conf, the vbitrate param to the
vcodec param (sent to mencoder) got lifted to 260, from 150. You can
make it what you like to adjust the size/quality trade-off, and also
for
instance, you could change the "320:240" scaling if you like - you
would
just need to make the same weight/height corresponding change in the
flowplayer template.
Also, as mentioned in the indytube.conf at the above link, at some
version MEncoder stopped supporting the
"i_certify_that_my_video_stream_does_not_use_b_frames" flag and wont
transcode files if its used. Upgrading MEncoder to the latest version
should work easily though.
cheers
