So, after some trouble opening the program, I eventually got to editing my footage. Here's the only problem, whenever a medium to large effect comes into play, my frame rate takes a suicidal plunge down a cliff. This happened as well with Hitfilm 2, and I thought that this issue had been solved for Macs, but now I am encountering it again. The effect I noticed this on was the dragon's breath, and when it starts the video gets all choppy and laggy, any advice on what I should do? Otherwise, a great product that is fun and easy to use.
