Playing 720P video on the Powerbook G3 Pismo at full 24fps

some ghosting from the codec and Quicktime only sees 8:38 minutes of video
File is 4.3Gigs but quicktime only sees 288MB


Powerbook G3 (Pismo)
1Gig RAM
100Gig HD 5400RPM

Video encoder = Cinepak
1280x536
24 FPS

small video


enjoy

Cool but wouldn't Divx be a better choice quality wise with much less storage space needed?
It's an honest question as I don't know nothing about codecs.

I totally agree, Divx plays great at 640x### also MPEG1 at 720x480 on the Pismo
I was trying to see which codec I could use to play 720P videos

over 4 gigs and 14 hours to encode it's definitely not a good method :)
fyi encoding was done on a MacPro 1,1 and it was slooooow.

Ok. Thanks for the insights.
I did a quick read about the codec on wikipedia before I posted and it seems maybe understandable that it encodes so slow on your mac pro as it is quite old and reaching back as far as 68xxx processors so maybe it's lacking code optimization for such newer environments.
What encoder did you use and on what OS version?

I used QuickTime 7 on the Macpro 1,1 running El Capitain

The codec is Cinepak in the AVI export. Not sure how to check which the codec
 
Use MPEG2 i.e. as used by DVD? Handbrake on your Mac Pro should be able to do this. There should be good codec support for that in OS 9; possibly even (some) hardware support via the Pismo's GPU. File size won't be the problem here (unless it's so big the Pismo's HDD can't send the data fast enough) - it's the complexity of the codec. Fancier codecs like h.264 will give much smaller file sizes, but at the expense of requiring sophisticated processing to unpack them. That will be the real issue on a 400/500MHz G3.

Also - are you intending to watch this on an external monitor? If not, the Pismo only has a 1024 x 768 display anyway, so there would be no point making it decode high resolution video and then downsampling it to the resolution of the LCD.

Will give it a try , thanks 👍
