More videos for every client. Always on brand

Set each client’s brand guidelines once. Quelta makes videos to them for every campaign, market and language, and checks every creative, yours or a contractor’s, before the client sees it.

What Quelta solves

More creatives without more people

  1. Every client has its own brand book

    Problem
    Colours, tone of voice, banned words and required disclaimers differ from client to client, and every video must follow them.
    Quelta
    Set each client’s guidelines once: tone, colours and fonts, logo, words to use and avoid, music and disclaimers. Every video follows them.
    Example
    A cosmetics client: no medical claims, a pastel palette, a female voice aged 30–40, the logo in the last 2 seconds.

  2. Clients want more creatives every week

    Problem
    Creatives wear out in days, and every new one takes the team hours.
    Quelta
    Quelta makes dozens of versions to the same guidelines: new hooks, angles, creators and lengths for testing.
    Example
    One brief → 20 versions for a two-week TikTok test.

  3. One campaign, many markets

    Problem
    Translating and re-voicing every video for every market is slow and expensive.
    Quelta
    Quelta translates and localizes each video: the language and voice, the creator, the captions and what the offer leads with, for every market of the client.
    Example
    A launch in 6 countries: one master video → 6 local versions (as in case 2).

  4. Creative QA takes hours

    Problem
    Checking every video by hand before it goes to the client or into the ad account is slow, and mistakes still slip through.
    Quelta
    Check any creative, yours or a contractor’s: a score, every mistake with a timecode and the fixes in order of impact.
    Example
    A contractor’s video: a 3-second logo, no hook, captions under the buttons. Caught before the client saw it.

  5. Proving the work to the client

    Problem
    It’s hard to explain why one version is better than another.
    Quelta
    Show the client the Quelta report: the score, the categories and what was fixed, before and after.
    Example
    Before 18, after 69: the client sees exactly what changed (case 3).

Private accessGeneration and the one-click fix are in private access: we open them to teams one by one and help with the setup. The check is free for everyone.

Localization

Every client market, language and audience

For each market Quelta changes the language and the voice, the creator, the captions and what the offer leads with, within the client’s guidelines. And it makes separate versions for different generations of buyers.

  • Always within the client’s guidelines
  • Language, voice and captions of each market
  • Versions for Gen Z, Millennials, Gen X and Baby Boomers
  • US

    United States · English

    Leads with: the price

    $69, not $120+ for a logo

  • DE

    Germany · German

    Leads with: quality and free returns

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.

Cases

What your clients get

A check that catches mistakes before launch, ads for three markets, and a new angle that Quelta found on its own.

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.

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 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.

Questions and answers

Can each client have their own guidelines?

Yes. Guidelines are set per client: tone, colours and fonts, logo, words to use and avoid, music and required disclaimers. Every video for that client follows them.

Can we check videos made by others?

Yes. Any vertical video ad: yours, a contractor’s or the client’s. The preliminary check is free; the full check shows every mistake with a timecode and a fix.

Can the client see the report?

Yes. Every report has its own link: send it to the client, and they will see the score, the mistakes and the fixes.

How do we start?

Leave a request. We open private access to agencies one by one, help set up the first clients and agree the volumes.
