I am so new at using this software. I tried the demo standard version online and I like what I see. However, my video seems to be moving in slow motion. Before I purchase the software, I am trying to figure out if this just occurred because I am use the "demo" version. I am trying to put a black screen behind a video and everything seemed to go in slow motion. The words the speaker is saying is not lining up at the right moment he speaks.
