About Trim video

Trim video is a video ad production tool that helps advertisers make new bumper ads from their longer video assets quickly. Trim video uses Google's AI to simplify the process of bumper ad creation by identifying the most important frames in a long ad and turning them into 6-second videos. It also has simple editing features that allow advertisers to modify the final output.

This article explains what Trim video is, the benefit from using it, and how it works.



  • Save time and resources: Trim video is a simple, and easy-to-use, self-service tool that helps you create bumper ads within minutes.
  • Inspire new ad concepts: It can serve as a starting point when developing custom bumper ads with your creative team or agency partners.
  • Improve ad performance: Bumper ads can help improve ad recall and brand awareness of your campaigns. Advertisers who combined video campaigns with bumper ads drove significant lift in ad recall and brand awareness than advertisers who bought either format on its own.
