Google Ads is expanding its use of generative AI to adapt existing Performance Max videos for missing aspect ratios. Instead of relying only on a crop, the system can extend a scene in some frames to fill horizontal, square, or vertical space. One source video can therefore produce variations eligible for more placements.
The convenience creates a larger control question for creative teams. If product packaging, a legal qualifier, a price, a person, a retail environment, or a brand code sits near the edge, generated space may introduce an inaccurate detail. Google's automation can broaden media coverage, but it does not remove the advertiser's responsibility for brand accuracy and approval.
What changed?
According to Search Engine Land's August 17 report, Google sent account communications about an upgrade that extends existing Performance Max video ads into missing ratios. The message described generative scene extension beyond cropping and presented a September 4 preference window for some accounts.
Official Google documentation confirms the underlying capability. The Performance Max video automation page says Google AI can make vertical, square, and shorter versions from uploaded videos. It also locates the control under Asset optimization in Campaign settings, where advertisers can uncheck Enhancement under Video.
The two pieces of information should not be merged carelessly. The generative capability and campaign control are documented officially. The September 4 date comes from the account communication reported by Search Engine Land; Google's public help page does not present it as one universal deadline. Every advertiser should verify the notice, setting, and available help path in its own account.

Which videos and placements may be affected?
Performance Max serves across YouTube and other Google inventory, making horizontal 16:9, square 1:1, and vertical 9:16 assets important. When one ratio is missing, video automation can derive a variation from the available source. Google's official video asset guide explains recommended ratios and says advertisers can inspect automatically created videos in the asset report.
This does not mean every generated frame will be wrong. Simple backgrounds, centered products, and compositions with generous safe areas may extend successfully. Risk increases when readable packaging, multiple small products, crowded shelves, architectural lines, hands, faces, or legal text sit near the frame edge. The model completes visual probability; it does not consult the advertiser's product database.
Ads containing prices and promotional claims require extra care in Türkiye. If an “from” qualifier, installment term, date, stock limitation, pack size, or service condition disappears at the edge, the asset may become problematic beyond aesthetics. Regulated industries must also preserve approved claims and visual boundaries.
Where is the opportunity?
Many teams produce only a horizontal master and either leave vertical inventory unsupported or fill it with a last-minute center crop. Automation can reduce that gap with a fast starting variation. More eligible assets may increase access to inventory and give the campaign more learning options. The time saving is real for teams running large catalogs or always-on campaigns.
An automated variation and a purpose-built shoot still serve different roles. AI-assisted output is a distribution solution, not a replacement for a story written for Shorts, mobile YouTube, or other vertical surfaces. Framing, pace, title space, and the moment of value often need to be redesigned. Our content production approach treats aspect ratio as a narrative decision, not merely a canvas dimension.
Fark Studio's interpretation is that automation can be a controlled test area for low-risk, always-on work. When product accuracy, offer conditions, or reputation risk are high, humans should prepare the core ratios. Generative extension should provide backup coverage rather than replace the primary brand asset.
The capacity gain should also be used deliberately. If teams reinvest saved production time in safer source compositions, opening-frame tests, and documented creative learning, the feature can create real value. If not, it may simply produce a larger volume of assets that nobody has reviewed.

Confirmed facts and open questions
The confirmed facts are straightforward. Performance Max video automation can generate variations in different ratios and durations. The automation setting is available at campaign level, and advertisers can review created assets in reporting. Google's documentation explicitly describes both automatic video creation and the ability to turn the enhancement control off.
Open questions remain. The public documentation does not say whether the same upgrade will activate in every account on the same date, which source videos will use generative scene extension, or whether the preference date in account communications is identical across markets. Advertisers in Türkiye should confirm account state through the interface and their support path rather than relying only on a reported date.
Turning automation off does not solve every creative problem. Missing ratios may leave the campaign poorly represented in some placements or trigger other automatic video paths. The decision is broader than “AI on or off”: Does every ratio have an approved source? Who reviews automatic output and how often? What happens to the campaign when an error is found?
What should teams do now? A nine-step video-automation audit
1. Inventory campaigns. List Performance Max campaigns by spend, product risk, and available video ratios. Keep high spend and high brand risk as separate fields.
2. Check Asset optimization. Record the Video and Enhancement state in Campaign settings with a dated screenshot. If the account contains a notice or deadline, preserve its exact wording and date.
3. Find missing ratios. Confirm whether 16:9, 1:1, and 9:16 have human-approved videos. Put missing ratios for critical campaigns into production instead of assuming automation will solve them.
4. Score source-video risk. Treat edge-positioned products, text, faces, hands, architectural lines, and legal information as high risk. Reserve simple backgrounds and centered objects for controlled testing.
5. Review every frame. Do not approve from the thumbnail alone. Generated space, transitions, object continuity, packaging, price, and end card should remain accurate throughout.
6. Schedule asset-report reviews. Inspect automatically created assets daily after launch, then weekly. Record which variation appeared in which campaign.
7. Define legal and brand approval. Require pre-launch review for regulated sectors, temporary pricing, or licensed imagery. “The system generated it” does not transfer responsibility.
8. Compare performance properly. Report automated and human-made ratios separately across spend, viewability, watch behavior, clicks, conversions, and brand safety. A lower CPA alone does not make an inaccurate creative acceptable.
9. Prepare a rollback path. Document how to turn enhancement off, remove an asset, restrict the campaign, and upload an approved alternative when a problem appears.

Should the feature remain on or be turned off?
Look for three conditions before keeping it on: the source composition is suitable for extension, product and legal risk are low, and the team can review the asset report regularly. If those conditions are absent, keep the feature off initially and fill missing ratios through dedicated production. For medium-risk work, use a limited-budget test, a weekly creative review, and a clear stop threshold.
The decision should not be permanent. A new product, offer, or source video changes campaign risk. Google's capabilities may also broaden over time. Add creative origin and approval state to the monthly media audit so automation remains visible to the people accountable for the result.
