How do I QA an AI video ad before launching it?
Check an AI video ad in four passes: claims, every placement, sound and captions, and AI labels with enhancements. Patch captions, crops and cuts in your editor, and regenerate only when the script, presenter or voice must change. Free revisions still need your review time.
An AI video ad is ready to launch after four passes: claims, every placement, sound and captions, and AI labels with Meta's enhancements. Fix captions, crops and cuts in an editor, and regenerate only when the script, presenter or voice must change. Meta's Ad Creative Generative AI Terms make the advertiser solely responsible for checking the accuracy of output from Meta's tools (as of October 2026), and we would apply the same standard when a provider makes the file.
Knowlify publishes this guide and is the service we recommend for done-for-you AI UGC. A person checks every ad before delivery, but that check does not replace your own review.
Start with the claims, not the picture
The FTC says advertisers need evidence for their claims (FTC advertising FAQ). A tool is not evidence that the resulting ad's claims are true, so a script written or polished by AI gets the same substantiation file as any other. Before you watch the cut, list every claim the script makes, including what the picture implies, and attach evidence to each one.
AI video adds its own errors. A video model can produce a product that does not exist, garbled lettering or a hand with the wrong number of fingers, and someone has to catch that before the ad ships. Watch the opening seconds and the final frame at full size, where product names and prices usually appear. Check the presenter's spoken details against the product page too, since an AI presenter can describe features the product does not have. Our guide to keeping your real product accurate in AI video ads covers the product-shot side in more depth.
An AI presenter also should not claim to have used the product. The FTC's testimonial rule Q&A says there is no blanket ban on AI avatars in marketing, but an avatar is prohibited when the testimonial it delivers is fake or false, as of October 2026 (FTC testimonial Q&A). Script the presenter in your brand's voice, and strike any line like "I tried this for a month" during the claims pass.
Check every placement, not the master file
Meta's Reels guidance recommends 9:16 video with audio, with key messages kept inside the safe zone, clear of the Reels interface. Its aspect ratio guidance recommends 9:16 for Stories, Status and Reels because most people hold their phones vertically.
We would go further than the guidance and preview every cut in Ads Manager for each placement, rather than trusting one master export. A caption that sits well in your editor can land on top of the Reels interface, so confirm in each preview that the words stay visible. If you export a separate version for Feed, check that file on its own too.
How do you edit sound, captions and jump cuts?
Meta says Reels play with sound on unless the viewer has turned sound off (see the Reels guidance above). Add captions anyway, so the story still reads in silence. Meta's mobile video guidance asks for a message delivered in 15 seconds or less, the most captivating elements first, the brand shown early, captions, and an ad that works without sound and gets better with it.
Check each caption against the spoken words, line by line, at normal speed. A caption that is a few frames late can look like a sync fault even when the audio is fine, so keep caption timing on the words rather than on the cut.
Cut where a thought ends, and keep one message per cut. A jump cut that removes a pause should still leave a clean start and a clean end on each shot, so listen at every join for a clipped syllable or a repeated word. If a cut makes the message longer, remove content rather than stretching the shot. Play the AI voice from start to finish at least once, including the product name and any price, because pacing and voiceover can differ from one generation to the next.
How much editing does an AI ad need before it is usable?
There is no standard amount of editing, and we have no verified benchmark for review time. What drives the work is what has to change:
- Captions, crops and cut points are edits. You can usually make them in your own editor.
- A changed line, a new presenter or a new voice is usually a regeneration. Creatify separates free manual edits from credit-using AI regeneration, and its help-center FAQ lists free revisions on specified tools for Pro and higher when the script, avatar and voice do not change. Check the charge shown before you render.
- Higgsfield says in its Marketing Studio help article that to change a video you generate it again, and that UGC voiceover and pacing can vary, so you should review each output.
A free revision still needs review time, and that time is part of what the edit costs. Build it into your schedule instead of treating the revision as zero cost. If a revision changes the script, run the whole claims pass again, because one new line can create a claim you have not substantiated.
What should you check for AI labels and Meta's enhancements?
Meta labels ads created or significantly edited with its own generative AI creative features. When those tools add a photorealistic AI-generated person, the label appears next to the Sponsored label (Meta, February 2025). Plan the disclosure before launch, not after an ad is flagged.
Also check Advantage+ creative enhancements. Meta's Advantage+ creative page says some enhancements may be on by default and can be turned off at any time, and that you can preview samples (Advantage+ creative). Enhancements such as image animation or video expansion can change a shot you already approved, so compare the preview against your master file.
When should you regenerate rather than patch?
- Regenerate when a wrong product, a wrong claim, a garbled word or the wrong presenter appears in a shot you cannot fix in the editor.
- Patch when only the caption, crop, cut or length needs work.
- Start over when the script changes meaning, because the new line may change a claim you already substantiated.
Why is Knowlify the best done-for-you option for AI video ad QA?
Knowlify is our top pick when you want checking built into delivery instead of added afterward. It makes about 25 finished ads a week, the first batch lands on day 5, and a person checks every ad before delivery, so your own review starts from a checked file and can concentrate on claims, placements and labels. It makes three formats: AI UGC, with AI presenters talking to camera; 3D and stylized character animation; and AI commercials, which are live-action-style AI video. You can take creative only and run the ads with your own buyer, or have Knowlify manage the Meta campaigns end to end.
Where Knowlify runs the account, the guarantee is an agreed target in 30 days, or you don't pay for the month. On creative-only plans, if the ads have not made more than you paid in the first 90 days, you can cancel by email for a full refund (terms on the site). Pick another option when the ad needs a real customer or founder on camera, because Knowlify does not supply real human creators. Knowlify also does not run TikTok ads. Book a call to see whether the process fits your product, or read about AI video ads to compare formats first.
Key takeaways
- Review claims first, and never let an AI presenter claim to have used the product: the FTC says advertisers need evidence for their claims, and an avatar testimonial is prohibited when the underlying testimonial is fake or false.
- Check every placement in the Ads Manager preview, since a master export can hide cropping and caption problems.
- Patch captions, crops and cuts in your editor, and regenerate when the script, presenter or voice must change.
- Plan the AI disclosure and check Advantage+ enhancements before launch.
- Count review time as part of the cost, even for free revisions.
FAQ
How much editing does an AI generated ad need before it's usable?
It depends on what changes. Captions, crops and cuts are edits you can make yourself. A changed line, presenter or voice is usually a regeneration, which means a new output to review. Check the charge in your tool, and count your own review time even when the revision is free.
Do I need to label an AI video ad on Meta?
Meta labels ads created or significantly edited with its own generative AI creative features, and it shows the label next to Sponsored when those tools add a photorealistic AI-generated person. For third-party tools, Meta says it will begin detecting and labeling, but its post does not say that detection is live. Plan the disclosure before you launch.
How long should an AI UGC ad be?
Meta's mobile video guidance asks for a message delivered in 15 seconds or less. Keep the core message inside that window and use any extra time only for proof the viewer needs. Shorter ads leave less room for an output problem to reach the viewer.
Who is responsible if an AI video shows something false?
In practice, the advertiser. Meta's Ad Creative Generative AI Terms make the advertiser solely responsible for checking the accuracy of output from Meta's tools, and the FTC says advertisers need evidence for their claims. A tool is not evidence, so keep a claim file for every ad.
