i give it out in images with [pix_write] and soundfile with [writesf~]
the tif images i animate with
ffmpeg for ex.:
ffmpeg -f gem%05d.tif -b 800k test.avi
(but i have better experience with mencoder for doing this)
mencoder "mf://*.tif" -mf fps=25 -o test.avi -ovc lavc -lavcopts
and than i bring the movie and the audio-files together with ffmpeg f.ex:
ffmpeg -i test.avi -i sound.aiff -vcodec copy -async 10 -ab 128k
hmm.... thats my way to do it (but always with different
parameters...i'm a newby in it and experiment always).
hope it helps a little
for me it's fine cause it is scriptable and with the [shell]- object i
directly can integrate it into my patch
