BlitzReels Faceless Video Generation

Generate AI-powered faceless videos from a topic or script.

Cost Warning: Faceless generation consumes AI credits (AI script writing, image generation, voiceover, video assembly). You MUST present a plan to the user and get approval before calling any expensive endpoint.

Quick Start

# Full pipeline: topic → video
bash scripts/faceless.sh --topic "5 productivity tips" --duration 30 --voice rachel --style cinematic

# Dry run — show plan without executing
bash scripts/faceless.sh --topic "5 productivity tips" --dry-run

# From a user-provided script (paragraph breaks = scene breaks)
bash scripts/faceless.sh --script "First scene narration.\n\nSecond scene narration." --duration 60

Required Workflow

Always use plan mode. Before generating, present this plan to the user for approval:

1. Topic or script — What the video is about
2. Duration — 10–120 seconds (drives scene count)
3. Visual style — See references/visual-styles.md or GET /visual-styles
4. Voice — See references/voices.md or GET /voices
5. Image model — See references/models.md (default: gemini-2.5-flash)
6. Video model — See references/models.md (default: kling-2.1)
7. Output mode — Full video, storyboard-only (images), or images + audio
8. Captions — Enabled by default; optionally pick a caption style
9. Plan summary — Present all choices + "this will consume AI credits" warning
10. User approval → Execute

Input Modes

If both are provided, --script takes precedence.

Scripts

scripts/faceless.sh

Purpose-built end-to-end pipeline. Handles: create project → generate → poll → export → download URL.

faceless.sh --topic TEXT [--duration 30] [--voice rachel] [--style cinematic]
            [--image-model ID] [--video-model ID] [--video-duration SEC]
            [--storyboard-only] [--no-animated-video]
            [--aspect 9:16] [--captions true] [--caption-style ID]
            [--resolution 1080p] [--name TEXT] [--yes] [--dry-run]

Run bash scripts/faceless.sh --help for full usage.

scripts/blitzreels.sh

Generic API helper for ad-hoc calls. Requires BLITZREELS_ALLOW_EXPENSIVE=1 for expensive endpoints.

Faceless Request Body

{
  "topic": "5 morning routine tips",
  "duration_seconds": 30,

Generation Modes

References

• references/models.md — All image and video generation models with costs and capabilities
• references/voices.md — All available voice IDs, categories, and descriptions
• references/visual-styles.md — All available visual style IDs and descriptions

Safety

• faceless.sh prompts for confirmation before calling expensive endpoints (bypass with --yes)
• blitzreels.sh requires BLITZREELS_ALLOW_EXPENSIVE=1 for /faceless and /export paths
• Always present cost/plan to user before generation

Notes

• Use https://www.blitzreels.com/api/v1 as your base URL. https://blitzreels.com redirects to www, and some HTTP clients drop the Authorization header on redirects.
• POST /projects/{id}/faceless returns a plan and input_warnings to help you predict what will be generated.
