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.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

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.

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:

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:

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:

betterprompt generate instant-runway-try-on \
  [--input <key>=<value>] \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> 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):

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"}'
