Well I've been tinkering with my newly acquired 667 Powerbook and seeing how far I can push video under OS9.
For testing I used a couple of 720P movie trailers, MPEG Streamclip on my G5 to convert them and Quicktime Pro 6 on Mac OS9.
I found the optimum codec to be the Apple MPEG4 Compressor at 3 Mbs which surprised me as I previously thought compressed video on underpowered hardware was a no no.
I output the mpg files at 1129 X 635 (size of Quicktime window maximised) which isn't far off the magic 720P - bear in mind this is on a 667 Powerbook (no L3 cache) - I bet the higher machines can do 720P easily.
Another great thing about rendering to Apple MPEG4 is that it converts in a single pass in realtime or quicker.


I'd love to know if anyone is successful at playing 720P on OS9 and what machine? Judging by my effort I'd guess 800Mhz is the threshold?
