I just update my AMD Radeon Crimson driver to the latest, and found new feature added called Radeon ReLive.

In short, this is for game recorder. Perhaps valuable to those gamer over here who love to record and share their gaming experience...

I personally haven't experiment with this including the compatibility with Vegas Pro 14.
