I've been using a titler plugin called Heroglyph from a company called proDad that I like very well. It does things like the handwriting effect, moving titles along a map / route / path, and so on. Great plugin.
Now I see they have a new effects package called
Vitascene that does a variety of things (like film looks, rays of light, starburst, sparkles, etc.) with GPU acceleration for rendering.. It's an expensive package, looks like it combines some of the features from other popular plugins (films looks, Radiance, etc.).
I don't know if the new package is good, bad, whatever, but I find it encouraging that they are using GPU acceleration. Other than the magic bullet film looks plugin, I don't know of any others that do for Vegas.
I hope this becomes a trend for Vegas plugins!
