First off, what's the extension on the file. mp4, avi, mts, mkv, ogv, pss, etc?
I know Wondershare Editor can edit mts, but it will only speed up up to 2x or 4x?
I myself use WindowsMovieMaker 12 on Windows 7 Ult. SP1 64-bit. It you can literally type in how much you want to speed it up and save in 60fps. I use it for all of my videos personally.
What OS does the Surface4 run?
If it is Windows 7 or higher. I would suggest WinMovieMaker12.
There is also VideoPadEditor, but I am rather clueless on how to use it and even export videos from it. It's like a mix of Final Cut Pro and Sony Vegas.
The info ya can give will help out more and more what I could suggest. Also Happy Late Christmas, forgot to tell ya yesterday.
