# Instant Runway Try On > This prompt instructs an AI to generate a single, photorealistic 4‑second vertical runway video featuring a lifelike model built from provided identity attributes and wearing an uploaded outfit exactly as referenced, while maintaining a fixed cinematic runway environment, continuous forward-tracking camera move, realistic walk cycle with cloth physics, and embedded runway ambience audio, enforcing strict consistency and prohibiting any overlays, text, branding, cuts, or display of the reference image. - Skill: `betterpromptme/instant-runway-try-on` (Agent Skill) - Install (CLI): `npx skillmds@latest add betterpromptme/instant-runway-try-on` - Raw SKILL.md: https://api.skillmd.com/api/skills/betterpromptme/instant-runway-try-on/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: BetterPromptme (https://skillmd.com/u/betterpromptme) - Updated: 2026-09-10 - Page: https://skillmd.com/skills/betterpromptme/instant-runway-try-on --- ## What it does This prompt instructs an AI to generate a single, photorealistic 4‑second vertical runway video featuring a lifelike model built from provided identity attributes and wearing an uploaded outfit exactly as referenced, while maintaining a fixed cinematic runway environment, continuous forward-tracking camera move, realistic walk cycle with cloth physics, and embedded runway ambience audio, enforcing strict consistency and prohibiting any overlays, text, branding, cuts, or display of the reference image. > For more installation instructions go to https://raw.githubusercontent.com/BetterPromptme/skills/refs/heads/main/betterprompt/SKILL.md to check out this skill. ## Inputs ### textInputs Pass each text input using `--input =` flags. | Variable key | Required? | Description | Defaults | | --- | ---: | --- | --- | | `gender` | Optional | The model’s gender identity. | `male/female/other` | | `age_range` | Optional | The general age feel of the model. | `early 20s` | | `skin_tone` | Optional | Brief description of skin color. | `fair porcelain` | | `body_build` | Optional | Overall build or proportions. | `tall athletic` | | `walk_style` | Optional | How the model moves on the runway. | `smooth controlled runway walk with clean turns` | | `hair_style_color` | Optional | Hair length, style, and color. | `shoulder length wavy chestnut hair` | ### imageInputs This prompt requires **exactly 1 image**. You **must pass exactly 1 image flag** (no more, no fewer), in the order matching the descriptions below. | Index | Required | Description | Allowed CLI flags | | ---: | ---: | --- | --- | | 1 | Yes | Upload a photo of the outfit you want to try on | `--image-input-url ` or `--image-input-path ` | ### Models and options This skill's modality is: **`video`**. To discover which `model` values you can use (and which `options` keys/values are valid for each model), run: ```bash betterprompt resources --models-only --json ``` Then filter the returned JSON array to entries where `modality` is `"video"`. ## How to run ### Step 1: Collect inputs First, run `betterprompt resources --models-only --json` and filter to `modality: "video"` to discover valid models and available options: ```bash betterprompt resources --models-only --json ``` Use only the models and option values that appear in the filtered results. Then collect all inputs from the human: - Optional text inputs (use defaults if not provided by the human): - `gender` (default: `male/female/other`) - `age_range` (default: `early 20s`) - `skin_tone` (default: `fair porcelain`) - `body_build` (default: `tall athletic`) - `walk_style` (default: `smooth controlled runway walk with clean turns`) - `hair_style_color` (default: `shoulder length wavy chestnut hair`) - Required images: - **Exactly 1** images: image 1 (Upload a photo of the outfit you want to try on). Images must be provided in this order. - Optional: model and options. - Present the human with the default model **`sora-2`** and its available options. Look up `sora-2` in the `betterprompt resources` output (filtered to modality `"video"`) and show its `availableOptions` as: `key: val1, val2 (default), val3 | key2: ...`. Mark a value `(default)` if it matches these defaults: `{"seconds":"4","size":"720x1280"}`. - If the human does not specify, defaults are used: model `sora-2`, options `{"seconds":"4","size":"720x1280"}`. Other models from the resources call are also available. If the required images are missing, **ask the human for what's missing**. Do not assume or fabricate values. Tell the human: **"Please provide images in this order: image 1 (Upload a photo of the outfit you want to try on)"**. ### Step 2: Run via BetterPrompt CLI Use the frontmatter's `name` as the positional argument (for this skill, use `instant-runway-try-on`). Command form: ```bash betterprompt generate instant-runway-try-on \ [--input =] \ [--image-input-url ] \ [--image-input-path ] \ [--model ] \ [--options ] \ [--json] ``` Notes: - Pass each text input as a separate `--input =` flag. - Pass each image using `--image-input-url` or `--image-input-path`, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.). - If the human does **not** mention a model, **omit** `--model` and BetterPrompt will use the default model: **`sora-2`**. - If the human does **not** mention options, **omit** `--options` and BetterPrompt will use the default options: **`{"seconds":"4","size":"720x1280"}`**. - If the run times out, the response will include a `runId` you can use to fetch the result later. Example (using defaults shown above): ```bash betterprompt generate instant-runway-try-on \ --input gender=male/female/other \ --input 'age_range=early 20s' \ --input 'skin_tone=fair porcelain' \ --input 'body_build=tall athletic' \ --input 'walk_style=smooth controlled runway walk with clean turns' \ --input 'hair_style_color=shoulder length wavy chestnut hair' \ --image-input-url https://example.com/image1.png \ --model sora-2 \ --options '{"seconds":"4","size":"720x1280"}' ```
