I record my actions during performance, then later play them back into 
my patch with pix_write and writesf~ activated.  Pd uses 1000% CPU load, 
and stutters during rendering, but audio and video remain in sync.

I have the [gemwin] at 720x576 25fps, for PAL DVD rendering.

Then simply encode the TIFF files with your video software - I have a 
longwinded process that works with the following free tools:

for video:

convert
manypngtoppm [1]
ppmtoy4m
y4mscaler (because ppmtoy4m is crap at chroma subsampling)
mpeg2enc

for audio:

audacity (to trim to exact length, normalize volume, etc)
twolame

then:

mplex

and finally:

dvdauthor
mkisofs
growisofs

maybe recordmydesktop - but I seem to recall it supports only Ogg codecs...


BTW, I'm on Linux, but the above tools might work on OS X too.
