'System not fast enough...' question
Posted: Fri Nov 02, 2007 11:17 pm
While my system is not super-fast, it has dual 2 GHz Xeon processors and 2 GB of memory with fast SCSI drives... so I was surprised that I couldn't play back an intro / splash video.
It works if I turn off the audio. It works if I turn off the video, but it won't handle both together. There are a 3, 2-second Multiquence expands in the sequence with some cross-fading. The 18-second file is 217 Mb.
The video itself is 800 x 600, 30 fps, 22KHz stereo audio, CamStudio lossless AVI codec - plays fine in WinAmp (at 50% for both CPUs).
I tried shutting down all squashable applications and processes, but that made no difference -- this is Windows XP, by the way.
Perhaps one limiter is the 400MHz front side bus? It's a circa 2002 IBM workstation, built very conservatively.
Perhaps another is that the code doesn't take advantage of dual processors? During the stressful passage, one CPU is 75%, the second is 25%, so for some reason, Multiquence is not demanding all it can... ?? (Just noticed that more conventional video/audio in the same project uses less than 10% of both CPUs for playback.)
