I have a question, I use Pinnacle Studio 8 and with the Hollywood Fx I can make certain clips explode and fly away or make certain clips turn into Paper Airplanes,
before I buy Vegas,I was wondering can you do this with Vegas 3.0 or 4.0 or with Videofactory?
You can make clips explode and fly away with PluginPac, a free suite of plugins from http://www.debugmode.com/pluginpac/ . If you have more feature requests for plugins, drop a line to the developer of PluginPac (me).
I'd download the demo and play around with it to see if it suits your workflow. To be perfectly honest, to my mind there are more important things to consider than whether a program has a fancy transition that I might use once per decade.
In other words, Vegas can do lots of excellent stuff with superb results (more so with Satish's great plugin), but I haven't seen it do a 'plane' effect transition...
