I started with PowerPoint. Using a 3D model of Hubble (a free PPTX asset), I created a simple green screen video by using the morph transition between the slides, and publishing the PPTX as a video. I used a green rectangle shape as the background, because I knew that I wanted to use several videos as backgrounds for the floating space telescope. The addition of video backgrounds contributes to the 3D effect of the Hubble moving through space.
In Camtasia, I used the Remove a Color tool to remove the green background, and render it transparent. Then I completed the demo by adding:
- Several background videos (free assets from Pixabay)
- Text boxes and shapes
- Background music (free asset from Camtasia)
- Narration (text-to-speech)
Storyline is used to deliver the video. A couple of online Resources are included, so users can seek out further information if they desire.
