# Campaign creative

Agencies and in-house teams need a master that is right, then many exact adaptations of it, fast and on budget.
The common failures are drifting off-brand, re-inventing the layout in every format, and burning credits on variants that test nothing.

Follow `magnific-essentials` for pricing, project folders and waiting.
Prompt craft is in [image-prompt-craft.md](../magnific-essentials/references/image-prompt-craft.md).

## 1. Brief and project

From the request, settle: product or offer, audience, single message, mandatory elements (logo, legal line, price, CTA), channels and formats, languages, client, budget.
Find or create the client's project and pass `folderReference` on every call; agencies bill and review per project.

## 2. On-brand: use the brand kit

If the client has a kit, it owns colors, type, logo and imagery.
- Find it with `brand_kit_list` (`search` by name), read it with `brand_kit_get`. Several matches: ask; never guess.
- `images_generate` with `brandKitId` always runs Magnific One. Keep the prompt short: the subject plus hard constraints ("winter blend on a cabin table, snow outside, no text"). Do not restate palette, fonts, logo or tone.
- Use `templateSlug` (from the kit's `templates`) when the user asked for that format, and `channel` (for example `instagram_post`, `instagram_story`, `linkedin_post`, `youtube_thumbnail`, `print`) when you know the destination, so the kit's channel rules apply.
- Read `brandCheck` on the finished image (via `creations_wait` or `creations_get`) before calling it on-brand.
- Kit rules the client set (bans) are applied by the server; do not fight them in the prompt.
The full brand-kit procedure, including building a kit from a website, is in `guides_get` with `brand-kit`.

No kit: write the brand cues into a reusable style line (palette in words or hex, type feel, photographic tone) and repeat it in every prompt; offer to build a kit (`brand_kit_create` + `brand_kit_scrape_url`) if the client will come back.

## 3. Formats and safe zones

| Placement | Ratio | Notes |
|---|---|---|
| Instagram and Facebook feed | 4:5 (or 1:1) | 1080 x 1350 |
| Stories, Reels, TikTok | 9:16 | keep text out of the top 14% and bottom 20% |
| LinkedIn and X posts | 1:1 or 1.91:1 (use 16:9 if 1.91 is unavailable) | |
| YouTube thumbnail | 16:9 | 1280 x 720, readable at small size |
| Web hero, display leaderboard | 16:9, 3:1, 8:1 | very wide shapes need a `customSize` model (up to 8:1, or 16:1 on Seedream 5 Pro) |
| Print | per the printer's spec | deliver `tiff16` |

Not every model offers every ratio (Magnific One, for example, has no 4:5); use the closest supported ratio and adapt with `images_expand` or `images_crop`, or set exact `width` and `height` on a `customSize` model.
To adapt a finished ad to 4:5 (or any ratio `images_expand` and `images_crop` lack), use `design_auto_resize` with that ratio in `aspectRatios`: it keeps the layout as editable layers. In a coding agent, expanding to 3:4 and cropping to 4:5 locally also works. Do not regenerate the winner for a new ratio.

## 4. Master first, then adaptations

- Generate the master in its main format and get it approved (or pick the best of a `count` set).
- Adapt the approved master instead of regenerating per format:
  - `images_expand` to a wider or taller ratio keeps the art and generates the margins;
  - `images_crop` (with `auto: true` for subject-aware crops) for tighter ratios;
  - `design_auto_resize` turns a design into resized pages for many aspect ratios at once, with editable layers when it can;
  - `images_resize` for exact pixels.
- Regenerate per format only when the composition must truly change (a 9:16 story with the subject in a different place), and then pass the master as an `image` reference.
- Exception, brand kits: when the kit has a template or channel for a format, generate that format with its `templateSlug` and `channel` and the master as an `image` reference, so the kit's channel rules (logo position, safe zones) apply and each file gets its own `brandCheck`. A crop of another format skips both.
  Then crop or resize the result to the platform's exact size (for example 4:5 at 1080 x 1350 when the model has no 4:5).

## 5. Copy a reference layout

When the user wants "the same design with new copy" or "keep the layout":
- Pass the reference ad as the first `image` reference and write the layout explicitly: "Same layout as the reference: headline top left, product centered, logo top left, CTA button bottom right. New headline text: \"...\". New background: ...".
- Text-and-layout heavy designs render best on GPT image models (catalog `useFor` typography, text_layout); check `images_models_list`.
- For an edit that must keep everything except the copy, use the whole-image edit route of `precise-image-edits` with the ad as the first reference (`preciseEdit` when the edit model supports it).
- Quote exact copy, keep it short, and proofread the result. Long legal lines belong in the design tool.

## 6. Variants for testing

- Each variant should test one hypothesis (hook, headline angle, background scene, product framing, CTA), and the reply should say which.
- Six variants that differ randomly teach the team nothing; vary one dimension per test cell and hold the rest.
- Variants of one prompt = one call with `count`; different hypotheses = different calls, in parallel.
- In a grid that holds one dimension fixed while another varies (3 headlines on 2 scenes), the fixed one must be identical across its cells, or the test measures noise: make each scene once, then change only the headline on it with the whole-image edit route.
  Make each scene base from the original ad with that route, changing only the background, so the product, props, logo and button stay as approved; a base rebuilt from a prompt drifts (props and backgrounds get swapped).
  Without `preciseEdit` the edit model also redraws the rest of the ad, so compare each base with the original before you use it; for copy-only cells, setting the headline in a design tool keeps the cells identical.
- Keep variants in one format for the test; adapt only the winner.
- When the layout, logo and button must stay exactly as in the original ad, edit the original per variant (the whole-image edit route, see section 5) rather than regenerating the whole ad.
- Show the variants together (`creations_show` with all identifiers in chat apps) so the team compares them side by side.

## 7. Localization

Generate the text-free master once, then put each market's copy on it (in a design tool, or with the whole-image edit route of `precise-image-edits` for short headlines), rather than regenerating the image per language.
Quote the translated copy exactly; for right-to-left or CJK scripts, prefer models with strong typography and proofread.

## 8. Review and delivery

- For client review, follow the review rule in `magnific-essentials`.
- Deliver `png16` or `tiff16` for print and retouching, the generated PNG for digital.
- Report: each asset by format with its link, the credits spent, what each variant tests, and what still needs a human (final type, legal lines).
