Premiere Pro CS5 requires specific nVidia Quadro FX display cards to utilize the Mercury Engine. Imagine playing back several streams of multiple color corrected formats with filters, effects and titles from the timeline in realtime in native HD without rendering. Adobe has fired a shot across the bow of the Avid DNxHD and Apple ProRes ships. By being the first to use native Canon H.264 codec to support Canon 7D footage, Adobe has catered to shooters who are seriously considering using a DSLR with HD playback as their mainstream camera.
Adobe has definitely upped the ante when it comes to performance and compatibility. So much so that Red users will have to seriously take a look at what is the best solution for editing large 2K and 4K files. With the right display card, the Mercury Engine will easily speed up the finishing process.B & H: First Look at Adobe Premiere Pro CS5
