Adobe CS5 and Matrox MX02 (and RT.X2) editing systems
I have spent the past few months experimenting with Adobe's CS5 Premiere PRO editing software combined with the Matrox MXO2 mini with MAX hardware. The addition of an Adobe-approved, CUDA-enabled video card like the GeForce 470 GTX allows for editing multiple layers of video, titles, filters and effects in real-time without rendering.
This is possible due to Adobe's Mercury Playback Engine, introduced with CS5 Premiere PRO. The Mercury Playback Engine is native 64-bit, multicore, and GPU-accelerated to provide an amazingly fluid, real-time editing experience. The Mercury Playback Engine software and the Stream Processors/Processor Cores on the CUDA-enabled video card directly talk to each other, allowing the video magic to happen. The more processor cores on the video card the better the editing experience is.
