add-voiceover

add-voiceover is a command for coding agents from DojoCodingLabs/remotion-superpowers. It costs 44 tokens per session (520 once invoked), scanned A, original, MIT.

A command that creates spoken narration from a script and adds the resulting audio to a Remotion video. Text-to-speech means converting written words into a generated voice recording.

In plain words
What is it for?
Use it to create narration from supplied or newly written scripts, choose a listed voice and tone, and place the audio in the composition.
Why use it?
It avoids recording narration manually and connects the generated speech to the video project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-voiceover scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Add Voiceover — Generate & Integrate Narration

You are helping the user add a voiceover narration to their Remotion project.

Load the remotion-production skill for the voiceover-sync and audio-integration rules.

Workflow

1. Get the Script

If the user hasn't provided a script:

  • Ask what the video is about
  • Ask about tone (professional, casual, energetic, calm)
  • Write the narration script
  • Present for approval

2. Choose Voice

Available voices (via remotion-media TTS):

  • Eric — Warm, professional male (default)
  • Rachel — Clear, engaging female
  • Aria — Energetic female
  • Roger — Deep, authoritative male
  • Sarah — Friendly, conversational female
  • Laura — Calm, soothing female
  • Charlie — Casual, youthful male

For voice cloning or custom voices, use the dedicated ElevenLabs MCP (requires ELEVENLABS_API_KEY).

3. Generate TTS

Use remotion-media generate_tts:
- text: [the approved script]
- voice: [chosen voice]
- project_path: [project root path]

Record the returned file path and duration.

4. Wire into Composition

Add the voiceover <Audio> component:

import { Audio, staticFile } from "remotion";

// In your composition:
<Audio src={staticFile("[returned-file-path]")} volume={1} />

5. Adjust Composition Duration

If the voiceover is longer than the current composition:

// Update durationInFrames in the Composition registration
durationInFrames: Math.ceil([voiceover_duration_seconds] * fps) + 60 // +2s padding

6. Generate Captions (optional)

Offer to generate subtitles:

Use remotion-media generate_subtitles:
- input: [voiceover file path]
- project_path: [project root path]

7. Duck Background Music (if present)

If the project already has background music, lower its volume during voiceover. See audio-integration rule for the ducking pattern.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
