Cheapest AI Video Model for Ads:
Cost per Variant Compared

Of the two, Topview T1: $0.22 a second at 1080p at Topview's topview.ai launch price, against $0.585 a second for Seedance 2.5 at its official API price. Topview launched T1 on October 21, 2026 as its own model, pitched at 62% lower cost than Seedance 2.5, which works out at 2.66x the seconds for the same budget.

Three qualifications, because ad budgets live in the details:

• The 62% is Topview's in-app price. Its developer API lists T1 at $0.1649 a second at 720p, 28.66% off Seedance's official price.
• Inside Topview's own credits the gap is smaller. At 1080p T1 is 8.8 credits per 4 seconds and Seedance 2.5 is 14.8, so T1 uses 41% fewer credits.
• The saving is a ceiling. It assumes every shot stays on T1. Each shot you move to Seedance 2.5 brings the bill back toward its price.

We have not priced every model on the market here. These are the two we would shortlist for ads with people, voices and real-looking light.

An ad has to be accurate, legible and compliant, and it has to come in many versions. What follows is our working advice from making ads, not a measured result.

• Product accuracy. The label, logo, shape and color must match the real product, and models like to redraw packaging. Send clear product photos with every shot, or start from a real product photo as the first frame. T1 accepts up to 50 multimodal inputs per request on topview.ai; in AdAnt it takes a start frame instead of reference images, so the product photo goes in as the first frame.
• Readable text. Prices, offers and legal lines must be exact. Generated lettering is not; add every word of on-screen text in an editor.
• Claims and disclosure. A generated person who looks like a real customer, saying they got real results, can mislead. Ad platforms have their own rules on AI-generated people and on claims such as health or before-and-after results; read the current policy for each platform before you launch.
• Many variants. A test plan multiplies quickly: hooks times formats times audiences. A model that is cheap per second is only cheap if most takes are usable.
• Talking heads. Most performance ads are a person talking to camera. Lip-sync and a natural delivery matter more than cinematic camera work.

On faces, light and dialogue, the two models look close; neither launch clip shows a packshot or on-screen text. These comparisons come from Topview's launch campaign, and several of the launch-week posts are marked as paid promotion, so treat the posts as marketing and the clips as the evidence.

The talk-show clip is the closest thing in the launch set to a talking ad: a host in an olive suit behind a desk and a guest in a red satin dress on a leather armchair, trading lines in close-ups and two-shots, with a city skyline behind them. Faces, expressions and lip-sync look comparable on both sides. That is the shot a testimonial or explainer ad is built on.

The laundromat clip is a short drama: a lit storefront in the rain, the inside of a spinning washer, an old meter dial, a car at the curb, and a man and a woman arguing across a folding table, ending on a shot through a washer door. For ads, watch the object close-ups. The washer drum and the dial hold their shape on both models, but they are props, not branded products. Test your own packshot on both models before you trust either with a label.

Make every variant on T1, then move only the shots that fail to Seedance 2.5.

Keep the script, prompt and product references identical when you switch a shot, so the re-render still cuts against the rest of the ad.

Ten 15-second variants, with two takes per shot, is 300 seconds of 1080p generation: $66.00 on Topview T1 or $175.50 on Seedance 2.5 at its official API price. We assume two takes because talking-head shots usually land quickly; product shots may need more. The T1 column is Topview's topview.ai launch price.

AdAnt users can now make those variants on T1 directly: pick Topview T1 in Studio's video picker or ask the Creator for it by name. In AdAnt, T1 uses 60% fewer credits per second than Seedance 2.5 at 1080p, and 54% fewer at 720p. The AI UGC video workflow shows the examples and controls.

One person, one product, one claim you can prove, and every word of on-screen text left for the edit. A template for a 15-second talking-head variant:

Format: vertical, handheld phone footage, natural window light, no on-screen text.
Person: a woman in her thirties, short dark hair, gray sweatshirt, at a kitchen table. Match the reference images.
Product: [your product], held up to the camera label first. Match the product photos exactly; do not change the label.
Shot 1, 3 s, hook: she holds the product up and says one surprising, true line about it.
Shot 2, 7 s: she shows it in use and explains the one problem it solves.
Shot 3, 5 s: close-up of the product on the table; she says where to get it.
Sound: her voice and room tone. No music.

To make variants, change only the hook line in shot 1 and keep the rest identical, so the test measures the hook. Add the price, offer and any disclaimer in the editor, and write your own presenter: no real people, no lookalikes.
