Realtalk Character Generator

What it does

This prompt instructs an AI to direct and generate a 6–10 second, cinematic, hyper-realistic talking-head video based on a user-provided portrait, with the subject delivering a short supplied script in a specified emotional tone and setting. It defines realism requirements (accurate lip-sync, natural micro-expressions and gestures, subtle camera movement, warm lighting, clear audio with ambient sound, and shallow depth of field) while preserving the person’s identity and avoiding robotic motion. The outcome is a polished, authentic-looking announcement-style clip suitable for social media or updates, constrained by safety rules that limit misuse and require consent and non-misleading content.

Inputs

textInputs

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

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:

• Required text inputs:
  • script
• Optional text inputs (use defaults if not provided by the human):
  • setting (default: casual indoor room, bright studio, modern office,....)
  • emotion_tone (default: enthusiastic, friendly, confident, calm,...)
  • character_description (default: Lively young woman with short dark hair and natural makeup)
• 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":"8","size":"720x1280"}.
  • If the human does not specify, defaults are used: model sora-2, options {"seconds":"8","size":"720x1280"}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use realtalk-character-generator).

Command form:

betterprompt generate realtalk-character-generator \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• 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":"8","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 realtalk-character-generator \
  --input script=<value> \
  --input 'setting=casual indoor room, bright studio, modern office,....' \
  --input 'emotion_tone=enthusiastic, friendly, confident, calm,...' \
  --input 'character_description=Lively young woman with short dark hair and natural makeup' \
  --model sora-2 \
  --options '{"seconds":"8","size":"720x1280"}'
