Quicktime for Java

Hello everyone,
I have been using the Quicktime for Java SDK alot recently for serious work at my college to stream MPEG-4 video and encode in a variety of formats.

During my research I found that the QT for Java SDK gives access to all the popular media types as well as it’s own sprite and FX engine.

If one is only interested in doing 2D games (with sprites that fade in and out with variable alpha) is there a noticeable performance disparagy between the Java 2D standard and the Quicktime API?

It might be iterestting to note that QT4J doesn’t run on the 1.4.1 JRE for Mac OS X… kind a funny, but it’s Apple’s own fault for using JDirect for their QT4J version and then dropping JDirect for 1.4.1
