The video

How Quelta makes videos that sell in every market

Why generated videos fail, and how Quelta turns product photos into checked, localized videos for a whole catalog. Two minutes, with sound.

This video was made with the Quelta engine too: script, voice, motion and sound.

Scale

One button: videos for your whole catalog

Choose a scenario once. Quelta turns it into the same videos for every product: in one style, with the same presenter and voice, and checks each one. Hundreds of products, thousands, up to hundreds of thousands of SKUs.

  • New products get their videos as they arrive
  • The same style and presenter across the catalog
  • Every video checked before it reaches a card

Localization

Localized by meaning, not just by words

People in different countries buy the same product for different reasons. For every market Quelta changes not only the language and the subtitles, but what the video leads with, who presents it, the voice, the pace and the text on screen.

  • USUnited States · English

    $69, not $120+ for a logo

    Leads with: the price

  • DEGermany · German

    Kostenlose Rücksendung

    Leads with: quality and free returns

  • BRBrazil · Portuguese

    Em até 3x sem juros

    Leads with: installments and a discount

Examples of what one product can lead with in different markets.

What changes for each market

  • Language and subtitles
  • What the video leads with
  • Presenter and voice
  • Pace and delivery
  • Text on screen
  • A version for each generation

And for every generation of buyers

  • Gen Z

    Fast cuts, a creator their age, humour and trends, the price up front.

  • Millennials

    Reviews and proof, value for money, a clear benefit in the first seconds.

  • Generation X

    Facts, quality and guarantees, a calmer pace and a confident voice.

  • Baby Boomers

    Large captions, clear speech, trust, service and an easy way to order.

How it works

From product photos to videos for every market

You don’t write scripts or prompts for video generators. Quelta works out the scenario for your audience.

  1. Send your products

    Photos, a product feed or links to product pages. No filming, models or studio.

  2. Say where and to whom

    Markets, languages and platforms, and who buys: age, interests, what matters to them.

  3. Quelta builds the scenario

    From trends and what already sells in your category, for each market and audience. For the catalog, in the style of your photos.

  4. Checked and delivered

    Every video passes the Quelta check: product, text, hands and faces, hook and sound. Defects are fixed before delivery.

Quality

Where video generators fail, and how Quelta fixes it

Video generators make ads fast and cheap, but they break in ways that cost sales. Quelta closes each gap.

  • Extra fingers, distorted hands and faces

    Quality control reviews every frame and catches defects before delivery

  • Logos and labels turn into letter soup

    Text and packaging are checked against your product photos

  • The product changes shape and colour mid-shot

    The same product in every frame

  • A new face in every scene

    The same presenter and voice in every shot and every video

  • A long video can’t be made in one prompt

    The video is assembled from checked fragments, by the scenario

  • Nobody knows if the script will sell

    The scenario is built for the audience, from trends and top-converting ads

  • Every regeneration costs time and money

    Only the broken fragment is remade, with the best model for the task

Cases

One phone video in. Ads for every market out.

Three short stories: an ad for one market, ads for three markets, and a check that saved the budget.

Case 1

Seller · USA

Embroidered pet tees → a gift ad for the US

A home embroidery shop puts customers’ pets on tees from one photo. Great product, no ads.

Request
A 10-second phone video: the tee, the shop with 6 pets and “Make me an ad for the US”.
Quelta
Found the angle on its own: a gift reaction, a genre that sells custom gifts in the US. Then the creator, voices, captions and edit for TikTok.
Result
A 15-second ad, “I put my mom’s dog on a shirt”, for US pet owners aged 25–45.

  • Pet owners 25–45
Case 2

Seller · 3 markets

One perfume → Mexico, Brazil and Saudi Arabia

A man makes perfume in his kitchen: cedar, cardamom and smoke. So far only his friends buy it.

Request
“Sell it in Mexico, Brazil and Saudi Arabia.” One phone video, in English.
Quelta
Three angles, not three translations: a compliment magnet in Mexico, lasts all day in the heat in Brazil, cardamom as the scent of hospitality in Saudi Arabia.
Result
Three local ads in Spanish, Portuguese and Arabic: native creators, voices, captions and calls to action.
  • Mexico
  • Brazil
  • Saudi Arabia
Case 3

Check · USA

A $900 ad, 3 orders → 28 mistakes found

A small skincare brand paid $900 for a beautiful horizontal ad. It brought 3 orders.

Request
A check for TikTok in the US, audience: Millennials. 18 out of 100, 28 mistakes, 4 of them critical.
Quelta
Pinned every mistake to a timecode, with a fix: a 3-second logo at the start, horizontal 16:9, only a tiny URL as a call to action.
Result
She fixed the worst ones: 69 out of 100 on the re-check. It didn’t go viral, but the orders came back.

Start with a pilotPrivate access

Videos for your catalog, starting with one category

Tell us about your catalog, markets and volumes. We make the first videos for one category, so you can compare them with what you have now. Then the same scenarios cover the whole catalog.

  1. Send your products

    A product feed, links to product pages or photos for one category.

  2. Agree markets and audiences

    Countries, languages, platforms, generations of buyers and the quality threshold.

  3. Get the pilot videos

    Localized for each market, checked and ready to post.

  4. Scale to the catalog

    Every product, every market and every new arrival, in one style.

We don’t copy other people’s videos. Every video is new and about your product. We keep the mechanics that sell (script, pacing, delivery), not anyone’s footage, people or music.

Questions and answers

What is Quelta?

Quelta makes short videos that sell from product photos: for product cards, social media and ads. It works at catalog scale, localizes every video for each market by meaning, not just by words, and checks each one before delivery. Quelta also checks any video ad for free.

Who is it for?

Marketplaces that need video for thousands of product cards, sellers and brands with a catalog to promote, and agencies that make videos for many clients. We also make videos for you, turnkey: from the brief to the finished video.

How many videos can you make?

From one category for a pilot to your whole catalog: hundreds, thousands, up to hundreds of thousands of SKUs. One scenario turns into the same videos for every product, in one style, and each one is checked.

Is localization just a translation?

No. Besides the language and the subtitles, Quelta adapts what the video leads with to local buyers: in one market it is the price, in another installments or a discount, in a third quality and free returns. The presenter, the voice, the pace and the text on screen change too, and there can be separate versions for each generation of buyers.

Do we need to film anything?

No. Product photos, a product feed or links to product pages are enough. If you already have videos, Quelta can use them too.

How do you control the quality of so many videos?

Every video passes the Quelta check before delivery: the product, text and packaging against your photos, hands and faces, the hook, the pacing, the sound and the rules of each platform. A defective fragment is remade before you see the video.

Do you copy other people’s videos?

No. Every video is new and about your product. We keep the mechanics that sell (script, pacing, delivery), not anyone’s footage, people or music.

How do we start, and what does it cost?

With a pilot on one category. The price depends on volumes, markets and formats, so we quote it for each project. Leave a request and we will get in touch.

What is the free check?

Upload any vertical video ad up to 3 minutes or paste a link to a public post. In about a minute you get a preliminary 0–100 score for your platform, country and audience age, up to 5 videos a day, no sign-up. The full check shows every mistake with a timecode and a fix: the first one is free with a Google account, then packs from 10 for $19.

What happens to a video I check?

Without an account, the video and the report are kept for 7 days and then deleted automatically. In an account, the report stays until you delete it, and the video copy is kept for up to 6 months. We do not sell videos, do not share them except with the processors needed for the analysis and do not use them to train models. Details are in the Privacy Policy.

In which languages does it work?

The site and the check reports are in English, French, Spanish and German. Videos are made in any common language, for any market.
