Text-to-Video Prompting for Brands: A Working Style Guide
A working style guide to text-to-video prompting for brands: shot grammar, brand tokens, model quirks, and templates that survive real campaign work.
Our team keeps a shared prompt document for every brand we produce for. It is not a folder of clever one-off prompts. It is a style guide: a fixed sentence grammar, a short list of brand tokens, and a bank of pre-approved shot descriptions. When a new campaign spins up, nobody starts from a blank text box, and the output looks like it came from one brand instead of six freelancers. That document is the difference between text-to-video as a toy and text-to-video as a production system.
This post is the template for building that document. It assumes you are prompting across multiple models, because in 2026 no single model wins every shot type, and a brand style guide that only works on one model is a liability.
Why brands need a prompt style guide, not a prompt library
A prompt library collects outputs: "this prompt made a nice clip once." A style guide encodes decisions: "our brand always shoots at eye level, always in soft daylight, never uses whip pans." The library goes stale every time a model updates. The guide survives, because it describes your brand, not a model's quirks.
The practical test: hand your guide to someone who has never generated a video, point them at the AI video generator, and see if their third clip looks on-brand. If it does not, the guide is missing rules, not the person missing talent.
The sentence grammar that transfers across models
After running the same briefs through VEO 3.1, Kling O3, Hailuo 2.3, and Wan 2.7, the ordering that degrades least across all of them is:
Shot type → subject → action → setting → lighting → camera movement → grade/style → duration
One example, fully assembled:
Medium close-up of a runner tying trail shoes on a rocky overlook, golden hour side light, slow push-in, warm filmic grade with lifted blacks, 6 seconds.
Rules we enforce on top of the grammar:
- One subject, one action per prompt. Compound actions ("ties shoes then stands and waves") is where most models start improvising.
- No brand adjectives. "Premium," "luxurious," and "high-quality" do nothing measurable. Describe what premium looks like: materials, light, pace.
- Negations go last, and sparingly. "No text, no logos" works; a paragraph of exclusions confuses more than it constrains.
- Duration is part of the prompt discipline. A 5-second idea prompted as a 10-second clip produces 5 seconds of padding.
Brand tokens: the reusable half of every prompt
The second half of the style guide is a set of fixed phrases every prompt reuses. Ours typically has four:
| Token | What it locks | Example phrase |
|---|---|---|
| Light token | Time of day + quality | "soft overcast daylight, no hard shadows" |
| Palette token | Grade + color bias | "muted earth tones, gentle teal shadows" |
| Camera token | Movement vocabulary | "static or slow push-in only, tripod feel" |
| World token | Recurring environment | "minimal Scandinavian interior, pale oak" |
Every generated clip inherits all four tokens verbatim. When a client asks why our AI output "looks like a campaign" and their in-house tests look like a mood board explosion, this table is the whole answer. It is boring, and it works.
For product-led brands there is a fifth token that beats text entirely: a reference image. Models like Wan 2.7 reference-to-video and VEO 3.1 reference-to-video accept product or character reference images, which removes the hardest prompting problem (describing your exact product) from the text layer altogether.
Model quirks worth writing down
Cross-model prompting is not fully portable, so the guide needs a short "dialect" section. The quirks we currently annotate:
- Kling O3 rewards explicit camera language and reasons about physics well; it is the default for anything with believable object interaction.
- Hailuo 2.3 handles human motion and expressive faces strongly, but drifts on long environment descriptions; keep setting clauses short. The fast tier is our iteration model because cheap retries change how boldly you experiment.
- Wan 2.7 text-to-video follows staging instructions literally, which makes it good for layout-critical shots and unforgiving of vague ones.
- LTX 2.3 and Flux 3 generate native audio, so prompts should describe the soundscape ("distant traffic, soft room tone") or you inherit whatever the model imagines.
The dialect section should be dated. Model behavior shifts with versions, and a quirk note from three releases ago is worse than no note.
The iteration protocol: three passes, then stop
Unlimited regeneration is a budget leak. Our guide mandates a three-pass loop:
- Pass 1 — composition. Generate at the cheapest acceptable tier. Judge framing and action only. Ignore texture flaws.
- Pass 2 — one variable. Change exactly one clause (light, lens, or action verb). Changing two means you learn nothing from the result.
- Pass 3 — quality tier. Re-run the winning prompt on the premium model tier for the final asset.
If three passes have not produced a usable composition, the shot idea is wrong, not the prompt. Rewrite the shot. This single rule cut our per-campaign generation spend roughly 40% versus the "regenerate until pretty" habit most teams start with.
Keeping the guide alive
A style guide nobody updates becomes fiction within a quarter. Lightweight maintenance that has worked for us:
- Every failed prompt that took more than three passes gets a one-line post-mortem in the doc.
- Every model version bump triggers a re-run of five benchmark prompts; diffs get noted in the dialect section.
- New writers onboard by regenerating five approved shots from the guide alone, no coaching. Gaps they hit become edits.
If writing prompts from scratch is the bottleneck, Versely's built-in prompt generator can expand a rough shot idea into the full grammar for you; we covered that workflow in Using an AI Prompt Generator to Write Better Video Prompts. And for the model-selection layer that sits underneath all of this, the live rankings on /models are the fastest way to sanity-check whether your defaults are still the right defaults.
FAQ
What makes text-to-video prompting different for brands than for individual creators?
Consistency requirements. A solo creator can chase whatever looks good today; a brand needs fifty clips across three months and four writers to feel like one voice. That forces fixed grammar, reusable tokens, and documented model dialects instead of ad-hoc prompting.
How long should a text-to-video prompt be?
Usually 30 to 60 words. Below that, the model fills gaps with its own defaults; far above that, most models start dropping clauses unpredictably. Structure matters more than length: one subject, one action, and your brand tokens.
Should I use the same prompt across different AI video models?
Use the same grammar and brand tokens, but expect to adjust the dialect. Camera language, negation handling, and audio description vary by model. A good style guide keeps 80% of the prompt portable and isolates the model-specific 20% in a quirks section.
How do I keep products accurate in text-to-video output?
Do not rely on text descriptions of your product; use reference-to-video models and feed actual product images. Text prompting then only has to handle scene, light, and motion, which is what it is good at.
How many regenerations are reasonable per shot?
Three focused passes: one for composition, one changing a single variable, one on the premium tier. If that fails, the problem is the shot concept. Teams that cap iterations spend meaningfully less and, counterintuitively, ship better clips because they fix ideas instead of gambling on seeds.
