video/screen capture

i want to record the output of an applet as a quicktime file, i know there is Snapz Pro 2.0 for apple but i'm on a pc, does anyone know of a similar program for xp?
saveFrame() isn't an option as it takes too long and this is a reactive audio applet visual thingy so needs to run at full speed.
cheers,
jon

I'd imagine if save frame is too slow, most other options will be as well... Maybe just use a faster computer?

Is it possible to tweak the code to use a pre-recorded QuickTime movie or WAV file and then output with saveFrame() - just for your example? It seems like it would be the smoothest way to go.
QuickTime Pro can join an image sequence into a movie and then add a sound track, so you'd be able to compress the images once you're finished demonstrating the sketch.

it's a sonia based reactive applet, unfortunately using saveframe() wont result in a synched movie file, there's just no way the loop can write a frame to disk in time.
i've been writing some code in the vein of: http://processing.org/discourse/yabb/board_Contributions_Audiov_isual_action_display_num_1086450442.html
but much simpler, just some ellipses pulsing in time to music, pretty hypnotic.
a much more complicated way to do this would be to actually open the wav file and read the frame data using that to effect/control stuff, you'd have all the time in the world then... but i've not got enough time or skill to go into into it that way.

Then what about using the copy() command, saving the images into memory, yourself, then saveframe() them all later when you're done.

following the ram-idea, why not have the saveFrame run in a different thread? so it won't slow down performance ..
loop():
grab screen -> move into array
second thread:
for each entry in array saveFrame()
maybe this will help save some more ram:
