The stop motion one is fun. It takes a video and then puts the stops in that make it look like you made it by stop motion.
You can also create a video slideshow using images and video. I know there are other programs that do this, but it’s super easy, and you can add sound.
Here is a slideshow I put together of our Doodle & Chat promo slides. I added sounds (for free) from bensound.com.
Hopefully this will help you if you are making video content for your school. Enjoy.
