...even as an avid user of quicktime I will readily admit that it
does some stupid things (like always transparently resizing/rescaling
dv, even if it's just to a scale of 1?!?)...so I've often wondered
where the "good" codecs are for video art use? It seems to me we
need a "vj codec", something like a modern, highquality, fullframe
photo-jpeg that is highly optimized and low in cpu usage, but most
work seems to be going into streaming architecture codecs...this is
certainly great for delivery, but it doesn't seem to be the best
(yet?) for screwing around in realtime...anyway, it's unfortunately
one project too far for me to jump into atm...

...pdp and gem have some nice interworking objects so that video from
one can go to the other, and these will just get better...and there
are "video-jack"-type efforts, I just don't think they've gotten much
momentum behind them (so little momentum that I can't recall the name
of the one I'm thinking about)...
