Google Ads is about to let generative AI reframe your existing Performance Max video ads into new aspect ratios, and the default is on. Here’s what’s actually changing, where this news is really coming from, and what to do before the deadline.
Google Ads is about to let generative AI reframe your existing Performance Max video ads into new aspect ratios, and the default is on.
If you run Performance Max campaigns with video assets, Google Ads has started notifying advertisers that generative AI will soon create missing aspect ratios, vertical and square cuts, from your existing horizontal videos. Creative you already approved and shipped gets reframed by a model, without going back through you for a second look, unless you opt out by September 4, 2026. That’s three days from today.

- Whether opting out is actually the right call

Last updated: September 1, 2026 by Afraz Alam, Founder, Techfee. Written after independently cross-checking two separate advertiser-sourced reports of this update against each other for the exact deadline and mechanics before writing a word of this.
What’s Actually Changing
Google Ads will use generative AI to automatically create the aspect ratios your Performance Max video assets are missing, turning a horizontal video into vertical and square versions so one upload can serve across more placements. This applies to video assets already in your account, not just new uploads. The setting defaults to on.
Where This News Is Actually Coming From
Here’s the part most coverage of this skips. As of this writing, there is no public Google blog post announcing this update. The story traces to Google Ads emailing individual advertisers directly. Two of them independently shared what they received: Menachem Ani of JXT Group posted it on X, and Arpan Banerjee posted it on LinkedIn, on different days, to different platforms. Two separate trade outlets, Search Engine Land and PPC News Feed, reported it independently, both citing an advertiser-forwarded email, not an official Google source.
Techfee treats that distinction as worth stating plainly, not glossing over. Two independent advertisers receiving the same email and reporting the same deadline and mechanics is real corroboration, genuinely more solid than a single unverified post. It’s still not the same as Google publishing this themselves, and until they do, treat the exact rollout timeline as advertiser-reported, not officially confirmed.
Does This Affect Your Existing Performance Max Video Ads?
Yes, directly. This isn’t limited to new creative you upload going forward, it applies to Performance Max video assets already live in your account. If you’ve approved a specific crop, framing, or brand safety margin on a video, an AI-generated vertical or square version of it could ship without a human reviewing that version first. It’s the same rollout pattern Techfee flagged when Google Ads shipped a wave of AI features across Ads and Analytics earlier this cycle: useful automation, opt-in review still worth doing yourself.
Should You Actually Opt Out?
If your video creative has brand-sensitive framing, opt out before September 4. If it’s simple and center-framed, letting this run is a reasonable bet. The honest answer depends entirely on what your creative looks like, not a blanket yes or no.
Opt out by contacting your Google account team or submitting Google’s opt-out form, the exact mechanics weren’t detailed in either sourced report, so confirm the current process directly in your account. If you’d rather have someone audit your Performance Max creative and make this call for you before the deadline, here’s how I work with clients.
FAQ
What is Google’s Performance Max AI video update?
Google Ads is rolling out generative AI that automatically creates missing aspect ratios, vertical and square versions, from your existing horizontal Performance Max video assets. It applies to creative already in your account, and the setting defaults to on unless you opt out.
How do I opt out of Google’s AI video resizing?
Advertisers can opt out by contacting their Google account team or submitting Google’s opt-out form, according to two independent advertiser-sourced reports. The exact opt-out form and process weren’t detailed publicly as of this writing, so confirm the current steps directly through your Google Ads account or rep.
Does this affect my existing Performance Max video ads?
Yes. This applies to video assets already uploaded and running in your account, not only new creative going forward. Any AI-generated aspect ratio built from your existing video could serve without a fresh human review of that specific crop.
Is there an official Google announcement for this update?
Not as of this writing. The information comes from Google Ads emailing individual advertisers directly, two of whom independently shared it, reported separately by Search Engine Land and PPC News Feed. No public Google blog post has confirmed it yet, worth knowing before treating every detail as final.
My Take
The feature itself makes sense, one uploaded video serving more placements is a real efficiency win, and I’d probably leave it on for simple, center-framed creative. What I don’t love is the default-on setting applied retroactively to creative advertisers already approved, combined with Google not having published this themselves yet. I’m watching for the actual Google Ads Help Center page to confirm the mechanics once it exists, and once self-serve access to the opt-out flow is something I can click through myself, I’ll report back on how clean or messy that process actually is.
