Practical Ed Tech Summer Camp I talked about the idea of creating a gallery of b-roll media that your students can use in their slideshows and videos. That suggestion was part of a larger conversation about helping students avoid using another person's work and accidentally violating that person's copyright rights. One way to avoid any worry about copyright is by having students use media that they have created from scratch. Building up a gallery of media that is large enough for all of your students to use takes time. One way to build up the gallery is to create shared Box, Dropbox, or Google Drive folders that students put b-roll submissions into.
As the folks at Wistia explain and demonstrate in the video below, using b-roll footage can be a good way to improve your videos. Watch the video below to learn how they do it.
