Question

Audio + full motion not good on 800Mhz cpu

I created some full motion captures, added audio to them later and played them back on several computers.

the audio is compressed at 22Khz at 96 bit rate. The full motions are 15-40 seconds long. They play fine on computers (MAC or PC) with over 1 Gig processor and over 1 Gig or RAM. They completely hog cpu, stutter and stop on a machine with 512 RAM and 800 Mhz processor.

    On a related note, I've run into the similar issues while authoring, only I'm on a 2.4 GHz machine with 1 gig of RAM. Captivate is an utter RAM PIG.

    One thing that seems to help some is turning hardware acceleration OFF. This seems to free up some resources so that Captivate doesn't bog your machine quite so bad. Its a wonderful program overall, but it'd be nice if it were a little more optimized, performance-wise. Many operations are slow compared to some of the competition.

    Catbandit, these files are small once they are .swf's, 3-4 megs, and I've tried reducing the slides to 2 or 3. But it completely hogs my CPU. My task manager shows it spiking. So if the swf isn't big, what is causing the problem?

    I think it has something to do with how it cachesfull motion swf's and audio. I guess I could try opening the cp file in flash and see if the results are different.....not sure if full motions export.....have to see.

    Okay ... and what was it you expected, MICHAEL?

    1) 15-40 seconds of full-motion animation will generally create a very large video file ...

    2) A machine with less than 1 GB RAM and /or running at CPU speeds common several years ago (or more) will generally have trouble playing large video files - and you have both, low-end RAM and a low-end processor.

    I guess I'm not sure if you are looking for help, or are just passing along your own findings to others ... thanks!
