Google Ads is upgrading Performance Max video ads with a new asset optimisation feature that uses generative AI to create missing video aspect ratios, helping ads appear across more placements and potentially improving reach and viewing experience.
The feature builds on existing automatic resizing of horizontal videos into vertical and square formats.
If you do not want Google to use the new generative-AI video optimisation, you need to contact your account team or submit the opt-out form by 4 September 2026.
You can also change video optimisation settings later in your Google Ads account.
