Every product you sell now needs more than one video ad. The same launch has to run as 16:9 on YouTube and connected TV, 9:16 on TikTok, Reels and Shorts, 1:1 in the feed, and sometimes as a 2.39:1 cinema master. This guide explains how to turn a single product page into a ready-to-post video ad in every one of those formats, what each format is for, how much it should cost, and where an AI ad generator fits.
A product page already holds almost everything an ad needs: the product images, the description, the price, the selling points. An AI ad generator reads that page, follows your brand book, and builds a finished video from it. The better tools export the same ad in landscape, vertical and square in one pass, so a single job covers YouTube, TikTok, Instagram, Facebook and your own site. Nothing is filmed, and no one opens an editor. Paste one product page, and get ads ready for YouTube, Instagram, TikTok, TV and even cinema.
What "product page to video ad" actually means
The workflow is simple to describe. You give a tool the URL of a product or service page. The tool extracts the product images, the description, the benefits and the price. It writes a short script, lays out scenes that match your colours, fonts and tone, adds motion, captions and music, and renders a finished video. You download an MP4 you can upload to any ad platform. Nothing is filmed and no timeline editing is involved.
Two families of tools do this, and the difference matters. The first family builds UGC or avatar ads: an AI presenter, or a synthetic creator, talks about your product in a testimonial style built for social feeds. Tools such as Creatify and Oxolo work this way. The second family builds designed, brand-led ads: motion graphics driven by your brand book, closer to a commercial than to a selfie video. iReplay.tv's AI Ad Generator is in this second family. Both start from a URL. They produce very different videos, and they suit different placements, which is the next thing to get right.
Why one video is no longer enough: the format problem
The single biggest reason product video ads are expensive is that every placement wants a different shape. A 16:9 YouTube ad looks wrong as a 9:16 TikTok, and a vertical Reel wastes most of the screen on a desktop feed. Match the aspect ratio to how people already watch on each platform, and the same creative performs; ignore it, and the ad is letterboxed, cropped or skipped.
Here is the practical mapping most advertisers work from:
| Aspect ratio | Resolution | Where it runs |
|---|---|---|
| 16:9 (landscape) | 1920 x 1080 | YouTube, your website, connected TV and FAST channels, LinkedIn, X |
| 9:16 (vertical) | 1080 x 1920 | TikTok, Instagram Reels, YouTube Shorts, Facebook and Snapchat stories |
| 1:1 (square) | 1080 x 1080 | Instagram and Facebook feed, and as a safe fallback almost anywhere |
| 1.85:1 (cinema flat) | 4K DCP | Cinema pre-roll, in-venue screens |
| 2.39:1 (cinema scope) | 4K DCP | Cinema pre-roll, widescreen brand films |
The old way to cover that list was to brief a video editor, then pay again for every re-crop and every new product. The reason AI ad generators have taken off in ecommerce is that they collapse that per-format, per-product cost. The better ones render every ratio from a single job, so covering YouTube, TikTok, Reels and the feed is one click, not four briefs.
How to turn a product page into a video ad, step by step
Using iReplay.tv's AI Ad Generator, the flow is five steps and takes about fifteen to thirty-five minutes of rendering, most of which is unattended:
- Paste your product or service page URL. This is the source of truth for the copy, the images and the price.
- Add your brand book as a PDF. This is what keeps the ad on-brand: your colours, fonts and tone. No brand book yet? The tool gives you a ChatGPT prompt that generates one you can export to PDF and upload.
- Choose a duration, the output formats and a language. Pick 16:9, 9:16, 1:1, or the cinema masters, in any combination. The ad can speak the page's language automatically or one you select.
- Set the style and generate. Describe the rhythm you want, for example energetic with fast cuts, or calm and elegant, then start the job. The page updates itself while the AI writes, designs and renders.
- Download the finished ad. You get the MP4s, closed captions as WebVTT, and a matching music prompt you can paste into Suno to generate a soundtrack. Upload the files to any ad platform.
No editing skills are needed because there is no timeline to edit. You are filling in a short form, not learning software.

Formats and delivery that go beyond social
Most URL-to-video tools stop at social. The reason iReplay.tv's generator exists inside a broadcast company is that a product ad increasingly needs to run in places a social tool never touches, and it can deliver to all of them from the same job:
- Cinema. The tool can output a DCP-ready 4K master in flat (1.85:1) or scope (2.39:1), the format a cinema actually projects. Very few generators produce a real cinema deliverable.
- Broadcast and FAST TV. The encode can be conformed for TV ad insertion, with broadcast closed captions (CEA-708) alongside the web WebVTT track, so the same ad is valid on a linear channel.
- Connected TV squeezeback. For always-on channels, the tool can produce a squeezeback overlay: the live picture shrinks into a corner while your promo plays in the freed space, instead of interrupting the stream.
What an AI product video ad should cost
Pricing in this category ranges from budget tools at a few dollars a month to platforms at up to two hundred dollars a month, almost all sold as subscriptions. That model works if you produce ads constantly, and wastes money if you do not.
iReplay.tv's generator is priced the other way around. Your first ad is free when you bring your own Anthropic API key: the key covers the generation cost and is never stored after rendering. After that, you pay per ad with no monthly subscription, so the cost tracks how many ads you actually make. For a store that ships a handful of new products a month, paying per ad is usually cheaper than a seat you renew whether you use it or not.
Scaling from one product to a whole catalogue
Making one ad is a starting point. The harder problem for a store is turning the whole catalogue into ads without it becoming a full-time job, and two things make that realistic.
The first is bulk generation. Because every ad starts from a URL, a list of product URLs can become a library of ads, in every format, without briefing anything by hand. If you run an online store and want this at catalogue scale, you can request bulk generation from the tool directly.
The second is having somewhere to run them. iReplay.tv can turn a catalogue into an always-on TV channel, so a new product goes to air the moment you launch it, and it can run your ads as pre-roll or mid-roll on the channels streamed by My TV Channel. The product page becomes an ad, and the ad becomes airtime.
Frequently asked questions
Can I really make a video ad just from a URL?
Yes. An AI ad generator reads the product page at that URL, extracts the images, copy, benefits and price, and assembles a finished video from them. You do not upload footage or edit a timeline. With iReplay.tv you paste the URL, add a brand book PDF, choose your formats, and download the rendered ad.
What video formats do I get?
iReplay.tv's AI Ad Generator outputs 16:9 (landscape, for YouTube, web and TV), 9:16 (vertical, for TikTok, Reels and Shorts) and 1:1 (square, for feeds), plus optional 4K cinema masters in 1.85:1 and 2.39:1. You choose any combination and they are rendered from the same job. Closed captions (WebVTT) are always included.
Do I need video editing skills?
No. There is no timeline and no editing software. You fill in a short form: the product URL, a brand book, a duration, the output formats and a style. The AI handles scripting, design, motion, captions and music.
How much does it cost?
Your first ad is free when you bring your own Anthropic API key. After that you pay per ad, with no monthly subscription, so the cost matches how many ads you make rather than a recurring seat.
How long does it take to generate an ad?
Generating a finished video ad takes roughly fifteen to thirty-five minutes. The job runs unattended and the page updates automatically as the ad is written, designed, rendered and finalised.
Can I use these ads for TV or cinema, not just social?
Yes. Beyond social MP4s, the tool can produce a DCP-ready 4K cinema master (1.85:1 or 2.39:1), a broadcast-conformed encode with CEA-708 captions for TV ad insertion, and a connected-TV squeezeback overlay for always-on channels.
Will the ad match my brand?
Yes. You upload your brand book as a PDF and the ad follows your colours, fonts and tone. If you do not have a brand book, the tool provides a ChatGPT prompt that generates one you can export to PDF and upload.
Can I make ads for my whole catalogue?
Yes. Because each ad is generated from a product URL, a catalogue of URLs can be turned into a library of ads in every format. iReplay.tv offers bulk generation for ecommerce catalogues, and can run the resulting ads on TV channels as pre-roll or mid-roll.
Turn your product page into an ad
If you have a product or service page, you already have the raw material for a video ad in every format. The iReplay.tv AI Ad Generator is available on the web and as native apps for iPhone, iPad and Android. Your first ad is free with your own Anthropic API key, so you can see a finished ad from your own page before deciding anything.
iReplay.tv is run by a collective of streaming and broadcast engineers. If you need people rather than tools, for example to build a white-label streaming app or a FAST channel around your catalogue, you can also hire streaming and broadcast specialists directly.
