HOW TO ADD IMAGES
You can create a video of your group or a video with voiceover added to slides using Screencast-O-Matic (set up free account) or Apple users may want to use iMovie. A shareable link or a MOV file or a MP4 file format are usually the best outputs to turn it in -check with your instructor.
Create your script. If narrating over slides, you should not just be reading info off your slides - your narration should add to that.
Some built in computer microphones will be strong enough. Earbuds/headphones with microphone capability can also be used as a microphone.
Here are what outputs you can find in Screencast-O-Matic:
Upload your video, click on the paper clip
Options then come up for downloading an MP4 and an embed code
