How to make a product video in one run

  1. 1

    Put in your materials

    Product name, a brief (PDF, pasted text or product page URL) and 1–6 product photos. Drop them in as one zip, a folder or several files; photos, logo, end card, PDF and copy files are sorted automatically. Choose a length (15, 20 or 30 s) and a ratio.

  2. 2

    Check the estimate

    Before anything is made, the credits for each line are shown. You agree once.

  3. 3

    Press once

    Script, scene images, narration, checks and redraws, motion, BGM, captions and export run in one go.

  4. 4

    Edit and export

    Rewrite the copy or redraw one cut at a time, then download in 9:16, 1:1 or 16:9.

Checks every video goes through

The product looks as photographed

Product cuts use your photo as it is. AI-drawn scenes use the photo as a reference and are redrawn if the shape, color, label or logo differs.

Exaggerated claims

Guaranteed results, unsupported “No.1” and numbers or prices that are not in your brief are removed. The check follows Japanese advertising rules; check the rules of the market where you advertise.

First 3 seconds and the closing call

Cut 1 is a hook within 3 seconds. The last cut shows the product photo with the product name and a call to action.

No real people or other brands

References to celebrities and other companies’ brand or product names are removed from the script and image prompts.

FAQ

How much does an AI product video cost?

Each video uses credits. For a typical 20-second video with three AI-drawn scenes, the estimate lists the credits line by line before you agree. You can use the credits of a plan, or buy a single video without a plan (see the pricing section). There is no unlimited free generation.

How long are the videos? Can I get landscape?

You can choose 15, 20 or 30 seconds. The default is vertical (9:16); the same video can also be exported as square (1:1) and landscape (16:9).

Will the product’s shape, color and logo stay intact?

Product cuts use the photo you upload as it is. AI-drawn scenes use the photo as a reference and are redrawn automatically if it differs. Cuts that cannot be fixed are replaced with the photo.

What happens to claims that break advertising rules?

Absolute claims, drug-like effects, “No.1” without a source and numbers that are not in your brief are removed from the script. The check follows Japanese rules. The final wording is the advertiser’s responsibility.

Can I make one without a brief?

Yes. A product page URL or a few pasted lines of features are enough. PDFs up to 3 MB can be read. You can also put everything in one zip.

Which language will the video be in?

Currently Japanese: narration and on-screen text are generated in Japanese, and the editing screen is in Japanese. Other languages are not supported yet; this page will be updated when they are.

Can I use the video on TikTok, Instagram Reels and YouTube Shorts?

It is exported as a vertical MP4 (9:16, 1080×1920) you can post as it is, with a notice at the end that it was made with AI. You can use it in ads, social media and shop pages. Upload only photos and documents you have the right to use.
