Called PowerDirector, it'll be available on Windows 8 launch day and will retail for around 10 to 15 bucks as a standalone app in the Windows Store -- should you spring for the full version of PowerDirector, the finger-friendly version's free.
And, the fact that it dovetails with Cyberlink's more powerful desktop editing tools means that PowerDirector provides something for just about any mobile movie maker.
PowerDirector provides several Magicstyle templates ("themes" in Apple parlance) to fancify your vids, and you can mix in music from your personal tunes collection as well.
PowerDirector gives Windows filmmakers the ability to import multiple types of video (including mpeg 2, h.264, and mkv files) and trim thos clips using taps, pinches and swipes, like its counterpart for iOS. It also outputs finished work in up to 1080p resolution.
