another way to record your performances is to mirror your display and feed the output with a dv camera or some other device.

this will limit the quality.

recording your actions is brilliant but a lot of effort during patching.

in fact, not so much effort. specially if you use this abstractions. you just have to insert a [rec_play_any data_name] on every connections you need
to record. then the [master_rec_play] allow you to record everything in a qlist, and play
it latter in order to record sound/images.

this is known to gives good result.

the single magic line i use to create a movie is :

mencoder -oac mp3lame -lameopts cbr:br=256:aq=0 -audiofile rec_.wav -fps 50 -ss
0 -ovc xvid -xvidencopts bitrate=5000 -vop scale=640:480 mf://*.jpg -o out.avi

Meanwhile, what recommendations does anyone have for other methods of making a DVD of Gem output,

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

*not* necessarily involving having Gem itself create a file?

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.
