There are important guidelines to keep in mind for ads with videos.

Upload up to 25 videos within 24 hours.
Upload videos from a desktop computer not from a mobile device.
Ensure ads meet LinkedIn’s advertising guidelines.
Promoted ads with embedded video links from third party sites will not autoplay or be redirected to the video landing page if they have a Lead Gen Form attached. Instead, the scraped image will be displayed and the ad will be subject to LinkedIn’s Lead Gen Forms.
