Videos and other forms of interactive media can be embedded in your Pressbooks webbook.
PDF, digital PDF, and EPUB 2 files do not support embedded videos. If you place a video in your book and export the book to any of these file formats, your videos will display as links that allow readers to find the video online.
Embedded videos are supported in the EPUB 3 format. However, this format may not be accepted by your ebook distributor. In addition, the EPUB 3 file format is still in beta testing on the Pressbooks platform. As such, we cannot offer support for any technical issues you may face.
