Google Ads AI Video Resizing 2026: What Malta Advertisers Must Decide Before 4 September

On 17 August 2026, Google began emailing Performance Max advertisers to tell them something that deserves more attention than a routine product note: Google will now use generative AI to create missing aspect ratios from video assets you have already uploaded. Not future uploads. The videos sitting in your campaigns right now, the ones your team scripted, filmed, approved and shipped, can be reframed and extended by a model without going back through anyone for a second look.

If you do not want that, you have a deadline. Advertisers can opt out by contacting their Google account team or submitting Google's opt-out form by 4 September 2026. Miss it and the setting applies by default, although video settings remain changeable inside the account afterwards.

For most Maltese advertisers this is genuinely useful. For a handful, it is a brand-safety problem. The point of this guide is to help you work out which one you are before the window closes. If you would rather have someone audit your account and make the call with you, that is the day job over at our Google Ads Malta service.

What Is Google Ads AI Video Resizing?

Google Ads AI video resizing is an asset optimisation upgrade for Performance Max campaigns. Where a campaign is missing a video in a particular aspect ratio, Google's generative AI will produce that version from the video you already supplied, so your creative becomes eligible for inventory it previously could not fill.

Google's stated goal is to maximise video ad reach while improving the viewing experience. In plain terms: YouTube Shorts, in-feed placements and Discover surfaces favour vertical and square video. If you only uploaded a 16:9 landscape ad, you were quietly locked out of a meaningful share of impressions. This update fills that gap for you.

How this differs from the old video enhancements

Performance Max has offered video enhancements for a while. Those tools could already crop and convert horizontal video into vertical and square formats, and shorten long videos into snappier cuts. That was mechanical: reframing, trimming, letterboxing.

The 2026 update is different in kind, not just degree. Generative AI does not simply crop into the existing frame; it extends the video to fill the missing space. The model invents pixels that were never shot. A landscape product shot becomes a 9:16 vertical with AI-generated background above and below the original frame. That is a meaningfully bigger creative decision than a crop, and it is why the opt-out exists at all.

What the 4 September deadline actually means

To be precise about the mechanics, because the messaging has caused some confusion:

• The upgrade applies to existing Performance Max video assets, not only new uploads.
• Advertisers who want to prevent it can contact their Google account management team or submit Google's opt-out form by 4 September 2026.
• Video settings can still be changed at any time from inside the Google Ads account after that date, so this is not an irreversible one-way door, but the default flips if you do nothing.
• Managed accounts with a Google rep have the easier route; self-serve advertisers, which is most Maltese SMEs, need to use the form.

Why This Matters More Than a Settings Change

1. It applies to creative you already approved

Most automation updates change how your ads are delivered. This one changes what your ads look like. If your video features a product, a price, a person, a logo placement or a regulatory disclaimer, an AI-extended frame can shift, crop or surround those elements in ways you did not sign off on. For anyone with brand guidelines, that is a review item, not a checkbox.

2. Reach and control are genuinely in tension here

The upside is real. Vertical inventory is where the attention is, and producing every format natively is expensive. If you are a five-person business in Malta with one video and no in-house editor, Google offering to generate the formats you never shot is a decent trade. The downside is equally real: you lose visibility over exactly what ran. There is no version of this where you get both maximum reach and total creative control, so decide which you are optimising for.

3. It is one more step in automated creative production

Read this alongside everything else Google shipped in 2026 and the direction is unmistakable. Performance Max has moved from automated media buying to automated creative production. Asset generation, automatically created assets, AI Max text customisation and now generative video extension all point the same way: you supply raw material and intent, the system assembles the ad. Treating creative as a fixed deliverable rather than a governed input is how advertisers get surprised. Building that governance into your wider paid media strategy is now part of the job.

The Malta Angle: Who Should Opt In and Who Should Not

Malta's market has a few characteristics that change the calculus compared to advice written for large UK or US accounts.

Creative production budgets are small, so free formats are valuable

The typical Maltese SME running Google Ads is not commissioning a five-format video shoot. Many are working with one landscape video made for the website, or a single clip repurposed from social. For these advertisers, AI-generated vertical and square versions unlock YouTube Shorts and in-feed inventory they were structurally excluded from. That is a real efficiency gain in a market where every euro of reach counts, and it is exactly the kind of leverage we look for when building lead generation systems in Malta on modest budgets.

On-screen text and bilingual creative are the biggest risk

Here is where local advertisers should be careful. A lot of Maltese creative carries burned-in on-screen text, English, Maltese or both, plus phone numbers, opening hours and offer terms. Generative extension can reposition the frame relative to that text, push it toward a safe-zone boundary, or surround it with invented background that clashes with your brand palette. If your video's message depends on text legibility rather than voiceover, review the generated versions closely or opt out.

Regulated and reputation-sensitive sectors should opt out by default

Malta has an unusually high concentration of businesses in financial services, iGaming-adjacent services, insurance, property and healthcare. In these sectors, ad creative often carries compliance-mandated wording, licence numbers or risk disclaimers, and the cost of a mangled frame is not a lower CTR, it is a regulatory conversation. If you operate under an MFSA, MGA or professional-body framework, the sensible default is to opt out before 4 September and evaluate generated formats deliberately later, in a controlled test.

Small market, high frequency, faster creative fatigue

Malta's addressable audience is tiny, which means frequency builds fast and the same people see your ads repeatedly. That cuts both ways here. More format coverage means more placements and potentially better frequency distribution across surfaces, which helps. But it also means any visual oddity in an AI-extended frame gets seen by the same small audience again and again. Local advertisers do not get the anonymity of a big market where a weak variant disappears into the noise.

A note on TikTok

Vertical video strategy inevitably raises TikTok. It is worth restating that TikTok Ads are not yet available in Malta, with a rollout expected during 2026. Until that happens, YouTube Shorts and Meta's Reels placements are where Maltese businesses get vertical video reach at scale, which is precisely why filling the 9:16 gap in your Performance Max assets matters more here than it might elsewhere. Many local brands are building organic TikTok audiences now so they are ready when the ad platform goes live.

A Simple Decision Framework

Run your account through these questions before 4 September.

Opt in (leave the default) if: your videos are simple, product or lifestyle-led, driven by voiceover rather than burned-in text; you have limited creative production capacity; you are chasing volume and incremental reach; and no regulator cares what your ad looks like.

Opt out if: your creative carries compliance wording, licence numbers or legal disclaimers; your brand guidelines are strict and enforced; your video is text-heavy or design-led; you sell a physical product where visual accuracy matters; or you simply want to test the feature deliberately rather than have it applied wholesale.

Opt out temporarily if you are unsure. This is the underrated option. Opting out by 4 September does not lock you out forever, video settings remain adjustable in-account. You can opt out now, review the feature properly in September, and switch it on for one campaign as a controlled test. That sequencing costs you a few weeks of incremental reach and buys you certainty.

What to Do This Week: A Practical Checklist

Audit which campaigns have video assets. Only Performance Max campaigns with uploaded video are affected. If your PMax campaigns are image and text only, this update does nothing to you today, though Google's asset generation roadmap suggests it will eventually.

Screenshot your current video assets. Before anything changes, capture what is running so you have a baseline to compare against. This takes ten minutes and saves an argument later.

Check your existing video enhancement settings. Open each Performance Max campaign's asset settings and note whether automatic video formats and enhancements are already enabled. Many advertisers do not know their current state.

Make the opt-in or opt-out decision and act on it. If you are opting out, submit Google's form or contact your account team before 4 September. If you have a Google rep, this is a two-minute email.

Set a review date in mid-September. If you stay opted in, check the asset-level and channel-level reports two to three weeks later. Google's 2026 Performance Max reporting now shows how Search, YouTube, Display, Discover, Gmail and Maps each contribute, so you can see whether new vertical inventory is actually producing conversions or just cheap impressions.

Judge it on outcomes, not aesthetics. The honest test is not whether the AI version looks as good as your original. It is whether total conversions at an acceptable cost went up. Sometimes a slightly imperfect vertical ad that reaches Shorts outperforms a beautiful landscape ad that reaches nobody.

The Strategic Read

The advertisers who will do well out of 2026 are not the ones who resist Google's automation, nor the ones who accept every default. They are the ones who treat each of these updates as a decision with a deadline, make it consciously, and measure the result. Generative video resizing is a good example: for a small Maltese business with one video and no editor, it is close to free upside. For a licensed financial services firm with mandated on-screen wording, it is an unnecessary risk. The feature is neutral; the fit is not.

What does not change is the underlying discipline. Clean conversion data, sensible targets, a landing page that converts and a clear view of what a lead is actually worth still determine whether any of this pays. Automation amplifies the quality of your inputs, in both directions. That is the core of how we approach growth strategy for Malta businesses: get the fundamentals right, then let the machines scale them.

Frequently Asked Questions

What is Google Ads AI video resizing?

It is an asset optimisation upgrade for Performance Max campaigns, announced on 17 August 2026, in which Google uses generative AI to create missing aspect ratios from video assets an advertiser has already uploaded. Unlike earlier video enhancements that simply cropped or trimmed footage, this extends the video to fill formats such as vertical 9:16 and square 1:1, making the creative eligible for more inventory across YouTube, Discover and Display.

How do I opt out of Google's AI video resizing?

Advertisers who do not want the generative AI optimisation applied can contact their Google account management team or submit Google's opt-out form by 4 September 2026. If you miss the deadline, the upgrade applies by default, but video settings can still be changed at any time from within the Google Ads account afterwards. Self-serve advertisers without a dedicated Google rep should use the form route.

Does AI video resizing apply to videos I already uploaded?

Yes, and this is the most important detail to understand. The upgrade applies to existing Performance Max video assets, not only to new uploads. Creative that was scripted, produced and approved months ago can be reframed by the model without further review, which is why brand-sensitive and regulated advertisers should make a deliberate decision rather than letting the default apply.

Will AI-generated video formats hurt my ad performance?

Not necessarily, and for many advertisers the opposite is likely. Filling missing aspect ratios makes your ads eligible for vertical and square placements you were previously excluded from, which usually increases reach and can lower CPMs. The risk is qualitative rather than quantitative: generated frames may not match brand guidelines, may reposition on-screen text, or may render products inaccurately. Judge it on conversions and cost per acquisition over a two to three week window, using Performance Max channel-level reporting to see where the new impressions are coming from.

Should Malta businesses opt out of Google Ads AI video resizing?

It depends on your sector and creative. Most Maltese SMEs with limited video production capacity and simple, voiceover-led creative should stay opted in, since free vertical and square formats unlock inventory they could not otherwise reach in a market where TikTok Ads are still unavailable. Businesses in financial services, iGaming-adjacent services, insurance, property and healthcare, or any brand with strict guidelines and burned-in on-screen text, should opt out before 4 September and test the feature deliberately later.

Not Sure Which Side of the Line You Are On?

The 4 September deadline is close, and the right answer depends on what is actually sitting in your account. If you want a second opinion on your Performance Max setup, your video assets and where your budget is leaking, book a strategy call or explore the Google Ads Malta service. We will tell you plainly whether this update is an opportunity or a risk for your business.
