A Video exercise features a short video (typically 3-4 minutes long) in which an instructor talks over a slide deck. The slides are created in DataCamp's Teach Editor to ensure a consistent look and feel, and the videos are turned into audio-only screencasts once the slides, their associated scripts, and the course's exercises are complete.
Guidelines
Video scripts between 300 to 400 words are best.
There is an upper limit of 550 words.
Most people speak at around 100 to 120 words per minute. These guidelines ensure videos remain shorter than 5 minutes. For more detailed information on how to create clean and effective Video exercises click on the following links.
