A screencast is a digital recording of a computer screen with audio narration. Screencasts can include telestrator (‘John Madden pen’) annotations. Narrated slideshows include audio recordings synchronized to images without hand-drawn annotations.
Screencasts and narrated slideshows can be created with two kinds of tools:
1. Browser-based: Create an account on the website and use a modern web browser like Google Chrome or FireFox to record, save and share it.
2. Client-based: Download and install software on a computing device to record and save.
