cube_rotate.zip
	Hi folks, I got interested in the 3D cube discussion: http://www.adobeforums.com/cgi-bin/webx?128@235.fMF1fdJBac4.4966590@.3bbccaec http://www.adobeforums.com/cgi-bin/webx?128@235.fMF1fdJBac4.4966598@.3bbcc0bf So I decided to do some experimenting with After Effects.  I was hoping that I might be able to find a way to get keyframe data from one application to the other to make a tumbling cube of video in PrEl, but wasn't able to get it to work the way I wanted. Making lemons out of lemonade, I've decided to share the results of my failed experiment.  This should be useful for those of you who don't want to mess around with one of the plug-ins mentioned in the threads.  Or if you're just a tinkerer like me. Chuck has posted the file, cube_rotate.zip, on his web site.  This zip file contains a still image (PNG, 720x540, square pixels, with alpha) sequence rendered out of After Effects of cube rotating in space.  The cube rotates 360 degrees on the X, Y, and Z axes independently, then XY, XZ, YZ, and XYZ.  Each rotation lasts 2 seconds. After you unzip the file, there are two ways to use it.  The simplest is to simply pick one of the stills and use it like Paul (in the threads) did to apply videos to the sides of the static cube.  Since there are lots of variations on the rotation, you can pick just about any cube angle you want.  I recommend using the Corner Pin effect to match your clips to the cube sides.  Paul used the 4-Point Garbage Matte, but I prefer the pinning method. You could also try to use the cube in motion.  Good luck with the keyframing. :)  If you're going to do that, there are a couple of steps to get the stills in as a : 1. Choose Add Media, and in the dialog choose the first PNG file only. 2. Check the "Numbered Stills" box at the bottom. 3. Click Open.  PrEl now imports all of the PNG files as frames of a single video clip. You'll probably want to render the timeline after placing the clip to get a smooth preview. If you want the cube to bounce around, you can trim out the type of rotation that you want, time stretch it or duplicate it on the timeline, and set position keyframes until your eyes bleed. Enjoy.
