Google Ads AI update for existing Performance Max video ads

In March, Google announced a new AI update that will apply to all existing Performance Max video ads that don’t already have a voice track. If you have provided headlines and descriptions, Google AI will use that copy to generate a realistic-sounding voiceover and add it to the existing base video. It will also save the new video with the AI voiceover as a new video asset.

Key points to know:

  • This feature only applies to Performance Max video ads that don’t already have a voice track. If you have video ads that already contain a voice track, they won’t be affected.
  • The feature is opt-out only, not opt-in. That means the setting turns on by default. If you don’t want a voiceover added to your PMax video ads, you’ll need to disable it by turning off video enhancement control in your video settings.
  • The feature launched March 20, 2026, so it’s possible some of your videos have already been enhanced if you had video enhancement control turned on.
