Video projects that you create in Ads Creative Studio can be exported to a Google Ads advertiser. In the future, you'll also be able to export them to Display & Video 360 and Campaign Manager 360.
Google Ads guidelines
To make sure that your projects are eligible to serve in Google Ads, make sure that all creative assets and landing pages meet Google Ads' video ad requirements.
You can also review specifications for each video ad format in the Display Specs Help Centre.
