Thanks, Dave! I really appreciate your kind comments! I think from the start I was interested in learning how to incorporate harmony (and other instrumentation) in my ukulele videos, so that was plenty of incentive to learn how to use GarageBand, the audio editing software in Mac. And then for editing visuals, I first started on iMovie, then moved to Final Cut Express. These programs seemed daunting at first, but I learned a little bit at a time. There's a ton of tutorial stuff on YouTube related to using these programs. The more editing techniques you learn, the more it opens up the imagination to try different kinds of stuff, and I love the creative challenge. Another bonus is that it makes collaboration possible, since you can combine audio and video from different participants.
