We recently starting making the move over to Wirecast for our live production. Last summer we started using Wirecast as a encoding box (Live streaming) and yesterday was the first day we used it for live shows. I am totally impressed. The flexibility that it provides is insane. you can create any type of shot you want. It also handles the video really well. No tearing and very few dropped frames. Another great feature is the video recorder. you can record any every possible format.

I cant wait to see what Wirecast 5 brings to the table. It took me about 3 years to move over from Vidblaster but at this point I think Wirecast has the advantage.
