Hi all, We've been developing video plug-ins for After Effects, Motion, and FCP with Quartz Composer (PlasmaFX for Digital Anarchy), and we've noticed a tremendous difference between running video through .qtz files in Tiger as opposed to Leopard.
The plug-ins run much faster through Tiger and are slow enough to be embarrassing in Leopard, even through Quartz Composer itself. I'm noticing that when I have a standard NTSC DV clip playing in Quartz Composer in Leopard, hitting Command-T to drop down the published parameters lags my Dual 2.66-Ghz Mac Pro with an nVidia 7300GT 256MB graphics card. This same machine had Tiger on it and ran all of the plug-ins smoothly with Final Cut Studio 2 prior to the Leopard release. Attempting to tweak or change any of my slider parameters causes the system to hang for several seconds prior to actually changing, whereas this same procedure in Tiger was extremely fluid and smooth; there's almost no interactivity to be had in this new version of Quartz Composer. The plug-ins ran fine in Motion 2.1.2, fairly close to real-time playback, but are just terribly slow in Motion 3, with only very simple coloration plug-ins running in real-time. We are fairly certain this slowdown is not on our end of the programming, so we're just wondering if any other developers out there are experiencing the same issues we are. -- ______________________ Marco Salsiccia http://www.digitalanarchy.com _______________________________________________ Do not post admin requests to the list.
