Video previews

Video previews let viewers see a 3-second preview of your video before watching. They provide a better browsing experience and can engage viewers by helping them find content that they want to watch.

When a viewer hovers over a video's thumbnail, they'll see a 3-second preview. After the  preview plays, viewers see the video's thumbnail.

Eligibility & viewing criteria

Viewers can watch video previews on the Home page, Search results page, Watch page, Subscriptions tab, and Trending tab on select desktop browsers (Chrome versions 32 and up and Opera version 19 and up). Video previews aren't currently available on mobile devices. 

Video previews are available for most videos that are longer than 30 seconds. They're automatically enabled for eligible videos, but may not be added to all videos that are longer than 30 seconds.

We use several criteria, including video topic and content, to determine what videos can have previews. If you don't see a preview for a video within two days, the video isn't eligible at this time.

Use video previews

Video previews are automatically enabled for eligible users and videos — you don't need to do anything to get them. Our system automatically selects a clip from the first half of the video to show.

Even if a video has a preview, you should still customize your video thumbnails. Thumbnails are seen when video preview is not active, such as when a viewer is seeing it on a page or a device that doesn't support previews.
