I am a new convert to this whole MAC thing. My mini is showing up up tomorrow and I had a couple questions. I am going to do some video editing for reviews of products. Basically I will need to watermark the videos and maybe splice in and out video if there is a mess up or something along those lines. Also, possibly a stop motion zoom in on something real fast with some text popping up. Nothing at the pro level for sure, but some basic editing. What app should I use? Is iMovie good for this? I think that comes free with the OS? Thoughts?
