Short-form video ads are video clips, most often 5–16 seconds long, that businesses use for promotion. Short video ads are much cheaper to make than their long-form counterparts but are equally if not more effective. These advertisements come in many different video ad formats, such as:

• Instream ads (pre-, mid-, or post-roll ads that play at different points of an online video clip)
• Outstream ads (video ads that usually appear while the user is scrolling through content on a web page)
• Mobile ads (a common mobile advertising practice for many free versions of mobile apps is to require users to watch a short video ad before being able to use a particular feature)
