What are the specs for Sponsored Brands video ads?

Videos are a great tool to expand on what your product does and how it can be useful to the consumer. The video must be 6-45 seconds long with a 16:9 aspect ratio. The file size must be less than 500MB. 

Videos cannot use Amazon trademarks, products, or references to Amazon’s products or services, and customer reviews are not permitted. For more information on the guidelines and rules for creating Sponsored Brands videos, visit Amazon’s Advertising Resource page.
