Videos lag and no rotation option

Splice is a well-designed and mostly functional app that I enjoy using, but they really need to work on better support for the footage so videos dont lag, and they REALLY need to add an option to rotate videos. Lots of cellphone videos these days are taken in portrait and when your video is landscape...its a hassle. Come on, Splice!
