For my video, I chose a very light and happy theme. I chose clouds as the background and a very flowy and upbeat song called Sunshine. Even the song title matches the sky theme. When I made this video first, it came out to be 1:07. And I couldn't figure out how to change the image pacing, but I had to do a free trial, which allowed me to image pace. I changed it the fast and eventually got it down to 0:29! I love the song I chose. It definitely makes you feel good about what you're watching and I think that's a key factor to making videos. Whatever theme you do, you have to stick to it to create a distinct feeling for your viewers. Mine was happy and go with the flow.
