VideoStudio Pro X4 has a nicely revised workspace, too. When you’re done editing, VideoStudio applies your edits to the high-definition version while you’re off having coffee (or sleeping). VideoStudio Pro X4 remains the only video editing application to offer a proxy editing mode, in which you can work on high-definition video in a low-resolution mode, thereby allowing you to use an underpowered computer. That said, VideoStudio Pro X4 remains a native 32-bit application, so none of its speed gains come from that angle. I experienced no crashes, and I never got the sense that I was overtaxing the application, even with high-definition content. But I did notice that, even without those patches, VideoStudio ran very smoothly on the systems I tested it with, including a dual-Xeon-based workstation and a Core i7-based laptop it previewed high-definition footage with no hiccups, its interface operated snappily, and it rendered output files relatively quickly (meaning, relative to how quickly I thought it should output, and relative to how quickly competitor Pinnacle Studio HD 15 rendered files).
Corel also says that the version I tested had some optimizations for Intel and AMD chips, but that it would be releasing additional “accelerator patches” after Intel and AMD released their own updates, so I did not run performance tests of my own.
