You mistake that accelerated transoding crap with AVIVO. The accerated thingy is something made for special mobile devices. You drag&drop media files to the device, and it's software will use the AMD transcoder for encoding. At least in theory, as no one ever used it.
AVIVO used to be what you're looking for, a video encoder bulit into CCC, which could do various formats quite quickly. Unfortunately it wasn't compatible with Windows 8, and it was discontinued and removed 1 year ago because of Microsoft's crap OS.
You have 2 chioces:
1. Install a driver package that is more than a year old with the AVIVO package.
2. Just use another encoder.
In my opinion #2 is a better choice.
