When she became a Christian, MeMaw (that's what us kids called her), heard how the butterfly is an object lesson of salvation. When we become saved, we are a new creation, like when the caterpillar turns into a butterfly. Ever since then, MeMaw loved butterflies. There were butterfly decorations all over her house.
Mom put me in charge of creating a slide show for her funeral. I decided that I would try to make a little swarm of butterflies moving across the screen be the transition from picture to picture. My plan was to make the slide show on Windows Movie Maker with a simple wipe across the screen for a transition, like this:
I then animated some butterflies in Blender like this:
I then overlapped the two videos at the point of transition for the finished result:
This project was quite a challenge for me, mainly because I didn't know much about overlapping videos in Blender. Also, in order for all this to work, the butterfly video had to have a transparent background, which I had no idea how to make. I did figure out how to do it though, and just in case there are some beginners like me who read my blog, I'll explain how I did it.
When you are in the render panel (F10), and you are selecting how you want your video saved, select Quick Time. A window box full of settings will then pull up. In the Depth drop down menu choose "Millions of Colors+". That "+" stands for transparency. Also be sure to press the "key", and "RGBA" buttons also in the render panel. If you've done all that, then you will have a transparent background to your animation! There is probably other ways of doing it, but that the only way I know of.
