ok thisis a little OT, but what DATA RATE are folks using for smooth playing movies?
I recall from the installation i was running a G5, with like 4- 8GB movies playing very smoothly on my laptop of course is a bit stuttery. i have been dumping out of final cut as DV-NTSC
Sorenson3 lets me tweal Data Rate but at picture cost.
any tips or hints?

i noticed that the [auto 1( message to a pix_Movie object plays the movie much smoother than the "number into right inlet" method. what's the reason for this ? is there something that can be done about it ?
...if you are playing a movie via the right inlet method, you definitely want to set a higher frame rate in [gemwin]...otherwise, by default you'll be poking along at 20fps, which might not be as smooth as ya want...
...also, you can just sent a [auto $1< message to the left inlet: this then tells the object to play a new frame for everytime it goes thru the render loop...and of course, this render loop speed is set by sending the [frame $1< message to the [gemwin]: don't make it faster than your computer can handle!
does this mean, i have to send [gemwin] a "frame 25" message to reproduce the film correctly ? (gemwin's default setting is 20, as far as i can remember)
...if you're playing with auto on, the higher frame message you set, the faster the movie plays...these two different ways are in there for flexibility: I usually use the counter method with a frame message of 60, and it's smooth as silk :-)

DV NTSC is pretty lightweight, and I found that my Tibook could do 3 streams pretty well but the fourth one started to hit the limit of the ard drive. The main drawback to DV is that it is limited to 720x480 or 720x576 only. Photo-jpeg has very nice image quality for a lossy codec, has fast decompression and can be any dimension. I think the new HD codecs included with FCP HD look fantastic and the 720p will play on my Tibook just fine. A G5 will like any of these just fine - uncompressed files are usually not worth the trade-off in massive disk resources required for their playback.
The codecs to avoid are Sorenson, H.26x, Divx and anything MPEG as those have very high compression rates and many use interframe compression (keyframes) which are not friendly to random access playback. Anything you commonly encounter on the web is not well suited for realtime use.
