Just because you shot video at 60p doesn't mean you have to set it to 24 or 30 fps to match your timeline. Set it to 40 or 50 fps or whatever for less slow motion.
Right click on the clip in the project manager and select Modify> Interpret Footage and set Assume this frame rate: to whatever you want.
To get the most out of the time warp tool use a tripod.
Please let us know how you make out.
