The Blackmagic Design DaVinci Resolve Color Correction Software, in addition to featuring many new functions, tools, and performance upgrades, also has a very much re-designed interface. Many software makers have not long ago begun redeveloping their applications to be more user-friendly and more efficient, and Blackmagic has done the same with Resolve. Where you previously likely had to go to school to learn Resolve, now you can learn a lot of its workflow on your own.
Resolve can natively be operated by keyboard and mouse, or you can instead use one of many compatible control surfaces, including Blackmagic's award-winning DaVinci Resolve Control Surface, a Tangent Devices Wave or Element Panel, JL Cooper's Eclipse CX, and Avid's Artist Color, or, simply in addition to your keyboard and mouse, a tablet and pen, like Wacom's Bamboo Tablet.
Resolve comes to you in a package including an installation disc and a user key dongle. The disc features the Mac version of Resolve. If you want the Windows version, disregard the included disc and download the Windows version from Blackmagic's website (from the "Support" page), and then active the software with the included dongle. The Windows version is compatible only with Window 7 64-bit. The "Support" page may at first allow you to think otherwise because it also lists Vista and XP as the possible options, but the listing is not Resolve-specific (you'll see a drop-down wherein you can select Resolve). Whether you're interested in the Mac or Windows version, you should disregard the included installation disc either way because it is surely not as up to date as the downloadable version of the software.
Please note that owners of Resolve 8 or 7 can download the new version free of charge on Blackmagic's website.
