How to make a Christmas ad with AI on a small-brand budget
The big retailers spend millions on a 90-second tearjerker. You have a product, a phone and about 6 weeks. That is enough, if you plan it like they do and produce it like you can.
Published 2026-10-12 by Cat Claw, the UK's create-and-distribute AI studio. About a 9 minute read.
The short version
- Start in mid-October. The big retailers launch in early November, Black Friday is 27 November 2026, and the gifting window shuts when the last posting dates pass in mid-December.
- Make 1 story, not 1 ad: a 30 to 45 second hero film plus 6 to 12 short cutdowns, product stills and a UGC-style version for paid social.
- Lock the look and the cast in stills before you spend on video, then draft cheap and render the survivors at full quality.
- Test 2 or 3 openings with A/B versions in Cut Studio. The first 3 seconds decide whether anyone sees your ending.
- UK ad rules apply to AI ads exactly as they do to filmed ones. Show the product as it really is and label prices and offers honestly.
- A full campaign comes to roughly 1,000 to 1,500 credits, which is the £49.99 pack plus change.
In the UK the Christmas advert is its own season. The big retailers' films land in early November and become the thing people talk about for a week, and every brand on social gets measured against that mood whether it likes it or not. For a small brand that used to mean sitting it out or posting a festive product shot and hoping.
AI changes what is possible on a small budget. You can now write a proper story, render a cinematic hero film with sound, cut it into a dozen versions for every platform and test the openings, all for the price of a decent lunch per week. This playbook runs from mid-October to Boxing Day, with what to make each week and what it costs in Cat Claw credits.
Why a small brand should make a Christmas ad at all
Quick answer. Yes, a small brand can make a Christmas ad with AI. Write a short story with one emotional turn and your product at the centre of it, lock the characters and look as stills, render a 30 to 45 second hero film in 5 to 10 second takes, then cut it into vertical versions for TikTok, Reels and Shorts and test the openings. In Cat Claw the whole campaign runs to roughly 1,000 to 1,500 credits.
Attention in November and December is cheap to get and expensive to buy. People are in the mood to watch something festive, they share it, and they are already shopping. Paid social costs climb steeply towards Black Friday, so the brands that win organically are the ones with something worth watching rather than something worth skipping.
You are not competing with the big films on budget, and you should not try. You are competing on specificity. A 40-second story about a real kind of customer, in a real kind of British kitchen, beats a generic snow globe every time, and AI makes that story affordable to produce in versions.
The calendar: what to make and when
| When | What to do | What you finish with |
|---|---|---|
| Mid to late October | Write the story, lock the cast and the look in stills, board every scene | A script, character boards and a storyboard |
| Late October to early November | Draft the hero film cheaply, then render the best takes at full quality | A 30 to 45 second hero film with sound |
| Early November | Cut vertical versions, render A/B openings, make product stills | 6 to 12 cutdowns, 2 or 3 tested openings, a still set |
| Black Friday week (27 to 30 November) | Run the offer version; keep the story version running alongside it | An offer cut with honest price and end date |
| 1 to mid-December | Push the gifting angle hard before the last posting dates | Gift-guide stills and short gifting cutdowns |
| Christmas week to Boxing Day | Thank-you post, behind the scenes, then a Boxing Day sale cut if you run one | A warm close and a sale version |
The date that matters most for a product business is not Christmas Day, it is your last guaranteed delivery date. Check Royal Mail's published last posting dates and your courier's, put your own cut-off in every caption from early December, and switch the message to gift cards and next-year delivery once it has passed.
Write the story before you open a model
The best British Christmas adverts share a shape: a small, relatable situation, one emotional turn, and a product that is part of the moment rather than the point of it. You can use the same shape at 40 seconds.
- 1 character the viewer recognises: the nan who cannot work the group chat, the student coming home for the first time, the dad who always burns the roasties.
- 1 small problem that feels true, set somewhere specific: a terraced house, a bus stop in the rain, a shop counter in a market town.
- 1 turn, where your product quietly solves it or makes the moment better. Not a demo, a moment.
- 1 line of dialogue or on-screen text that people could quote back. Short enough to be a caption.
- 1 clean end card: brand, product, the offer if there is one, and the order-by date.
Write it as 5 to 7 scenes of 5 to 10 seconds each. If a scene needs more than 2 sentences to describe, it is 2 scenes. Drama Studio's AI screenwriter can draft a 5-scene script from a premise of a few sentences for 3 credits, which is a quick way to get a first version to argue with.
Produce the hero film
- Lock the cast in stills. Generate one clean portrait of each character, then run it through Kitten Shot as a character board. Attach the board to every video take so the face, hair and jumper stay the same from scene to scene. Continuity is what makes a 40-second film feel like a film.
- Lock the look. Decide the palette and light once: warm tungsten interiors, blue hour outside, practical fairy lights in frame. Put the same 1 or 2 sentences about light and colour in every prompt. Christmas lives in the lighting, so be specific.
- Shoot your real product properly. Use a real photo of the product as a reference wherever it appears. The model invents the room, never the thing you sell. A clean, well-lit product shot does more here than any prompt.
- Draft cheap, finish premium. Run each scene on a draft tier first to check the action and framing, then render only the takes that work at full quality with native sound. Most scenes need 2 or 3 drafts; very few need 2 finals.
- Assemble in Cut Studio. Order the takes, trim them, add captions from the speech, a music bed and a title card, and level the sound for social. The edit itself is free; only AI fixes such as Extend +5s or Upscale to 4K cost credits.

One film, many cuts
The hero film is the source, not the campaign. What actually runs is a set of versions built from it, each shaped for where it will be seen.
| Version | Length and shape | Where it runs |
|---|---|---|
| Hero film | 30 to 45 seconds, 16:9 and 9:16 | YouTube, your website, the pinned post |
| Story cutdown | 15 to 20 seconds, 9:16 | Reels, TikTok, Shorts |
| Hook-first cutdown | 6 to 10 seconds, opens on the emotional turn | Paid social and Stories |
| UGC-style version | 15 to 30 seconds, creator to camera | TikTok and Meta ads |
| Offer cut | 10 to 15 seconds, price and end date on screen | Black Friday and Boxing Day |
| Stills | 1:1 and 4:5 frames from the film plus product shots | Feed posts, gift guides, email |
For the paid versions, use A/B versions in Cut Studio to render 2 or 3 openings of the same cut together, then post each one and let the feed tell you which holds. Marketing Studio's UGC mode makes the creator-to-camera version from a product photo and a brief, which is often the best performer for cold audiences.
The UK ad rules still apply to AI ads
The UK Code of Non-broadcast Advertising applies to an ad however it was made. The Advertising Standards Authority judges what the ad shows and says, not which tool produced it, so an AI-rendered ad is held to the same standard as a filmed one.
- Show the product as it really is. If the render makes it bigger, shinier or capable of something it cannot do, that is misleading, exactly as a doctored photo would be.
- Make offers honest. A Black Friday saving must be against a price you genuinely charged, and the end date must be real.
- Label paid partnerships. If a real creator posts your ad for payment or free product, it must be clearly marked as an ad.
- Do not imitate real people. Never generate a recognisable person, including a celebrity lookalike, without their permission.
- Be careful with children and alcohol. Christmas ads often feature both, and both carry extra rules.
This is general guidance, not legal advice. If your ad makes a specific claim about health, finance or price comparisons, read the relevant CAP guidance or ask the CAP Copy Advice team before you spend on media.
What it costs in credits
Every Cat Claw render shows its price before you commit, and failed renders refund automatically. The figures below are realistic ranges for a small campaign at the time of writing, with room for redoes.
| Item | Approximate credits |
|---|---|
| Script draft and character boards | 30 to 80 |
| Storyboard frames for 6 scenes | 30 to 60 |
| Video drafts for 6 scenes, 2 or 3 each | 200 to 400 |
| Final takes at full quality with sound | 350 to 600 |
| UGC-style version and offer cut | 150 to 250 |
| Product and gift-guide stills | 50 to 100 |
| Editing, A/B openings and posting | Free |
| Total | About 1,000 to 1,500 |
Credit packs at the time of writing are 100 credits for £4.99, 550 for £24.99, 1,200 for £49.99 and 3,000 for £109.99, so a full campaign with a hero film, a dozen cutdowns and a still set sits around the £49.99 pack. Posting to your connected socials through Puurfect Post costs nothing, and you can schedule posts for the dates in the calendar above. The cat is available for festive cameos and asks only for the warm spot by the radiator.
Frequently asked questions
Can I make a Christmas advert with AI?
Yes. Write a short story with one emotional turn, lock your characters and look in still images, render 5 to 10 second video takes with sound, then edit them into a 30 to 45 second hero film and shorter vertical versions. In Cat Claw the whole campaign, including cutdowns and stills, costs roughly 1,000 to 1,500 credits.
When should a small brand launch its Christmas ad in the UK?
Have it ready for early November, when the big retailers launch theirs and audiences start watching festive content. Start production in mid-October. Black Friday 2026 is 27 November, and the gifting push should peak before your last guaranteed delivery date in mid-December.
How long should a small-brand Christmas ad be?
Make a 30 to 45 second hero film, then cut 15 to 20 second story versions and 6 to 10 second hook-first versions from it. Most people will see a short version on a phone, so the first 3 seconds matter more than the length.
Do I have to say an ad was made with AI in the UK?
There is no general UK rule that every AI-made ad must be labelled as AI. The rule that matters is that the ad must not mislead, so the product must look and work as it really does, and offers must be honest. Some platforms ask you to label realistic AI content, so check each platform's own policy when you post.
How do I keep the same characters across every scene?
Generate one clean portrait of each character, turn it into a character board with Kitten Shot, and attach that board as a reference to every video take. Repeat the same short description of each character in every prompt as well.
How much does an AI Christmas ad cost in Cat Claw?
A full small-brand campaign, with a hero film, a UGC-style version, an offer cut and a set of stills, typically comes to 1,000 to 1,500 credits. The 1,200-credit pack is £49.99. Editing in Cut Studio, A/B openings and posting to socials are free.
