We’ve got a project file that we used a few years ago for our in-booth demos at tradeshows, but it’s actually quite simple if you’ve got access to After Effects or any other application that can create “masks” (which is pretty much all of them, isn’t it?)
You create a mask for the lower third “strip” (whatever shape you want). Then you can just load any particleIllusion-rendered footage you want. There are so many emitters that are perfect for “animated backgrounds” I don’t even know where to start naming them. (Try doing a search in particleView for “light” or “dots” as a start.)
If you don’t have an application that does masking, the project file we had used particleIllusion to create the mask from an image. Not as flexible as using your app’s mask features, but it worked. I may be able to find this project file and upload it somewhere if there’s enough interest.
