Now wouldn't this be a nice addition to Vegas?
Elemental Technologies' RapiHD™ Accelerator for Adobe Premiere® Pro CS4 sets a new standard for high-performance non-linear editing. Render Blu-ray quality AVC/H.264 files in real-time. Accelerate your workflow as high-quality scaling, cross-dissolves, and transition effects no longer run slowly. Best of all, this paradigm shift runs on hardware you already have: the NVIDIA Quadro graphics processing unit (GPU) in your computer. Sound too good to be true? It's not. Elemental Technologies’ RapiHD™ Accelerator for Adobe Premiere® Pro will be available in the fall of 2008.
