You can download the demo and see if it works.

I used to use Corel Video Studio X3 to edit my 60fps videos because Vegas Pro had such a hard time with them but since the update to 9e it works fine. The thing is, X3 uses proxies so it's not editing in the true native format. Pls keep in mind, to edit at true 1080p 60fps, you'll need a powerful machine. I'd much rather use Platinum 10, if it works, over X3. (;
