ai-media

name	ai-media
description	Generates images, videos, and audio via AI models (fal-ai MCP): cheap iteration models, expensive production finals, cost-estimate before generation. Trigger for 'generate an image', 'create a thumbnail', 'make a voiceover', 'AI video', 'text to speech for'. Not for design composition; use /ai-visual instead. Not for animation specs; use /ai-animation instead.

Media

Generate images, videos, and audio via fal.ai models over MCP. Progressive quality: iterate cheap, finalize expensive. Modes: image (text-to-image + editing), video (text/image-to-video), audio (speech, music, SFX, video-to-audio).

Workflow

Applies §10.2 YAGNI (don't pay for production models until composition is locked) and §10.1 KISS (simplest model that meets the need).

1. Gate: MCP — verify the fal.ai MCP server is configured. If missing, give setup instructions (key at fal.ai):

"fal-ai": {
  "command": "npx",
  "args": ["-y", "fal-ai-mcp-server"],
  "env": { "FAL_KEY": "YOUR_FAL_KEY_HERE" }
}

2. Estimate cost before generating; report the estimate for expensive runs (video especially): estimate_cost(model_name: "fal-ai/...", input: {...}).
3. Gate: ElevenLabs — for TTS via ElevenLabs, verify ELEVENLABS_API_KEY; else fall back to csm-1b or inform the user.
4. Generate progressively — cheap model for prompt iteration, lock with seed, then switch to the production model for finals.
5. Deliver — file path/URL, model + parameters, cost incurred, iteration suggestions if quality is low.

Progression: nano-banana-2 -> nano-banana-pro · seedance-1-0-pro -> veo-3 · csm-1b -> ElevenLabs.

Model Reference

Model	Type	Best For	Cost Tier
fal-ai/nano-banana-2	Image	Quick iterations, drafts, image editing	Low
fal-ai/nano-banana-pro	Image	Production images, realism, typography	Medium
fal-ai/seedance-1-0-pro	Video	Text-to-video, image-to-video, high motion	High
fal-ai/kling-video/v3/pro	Video	Text/image-to-video with native audio	High
fal-ai/veo-3	Video	Video with generated sound, high visual quality	High
fal-ai/csm-1b	Audio	Conversational text-to-speech	Low
fal-ai/thinksound	Audio	Video-to-audio (matching sounds from video)	Medium

• Image params: prompt (required); image_size (square, portrait_4_3, landscape_16_9, portrait_16_9, landscape_4_3); num_images (1-4); seed; guidance_scale (1-20, higher = more literal).
• Video params: prompt (required); duration ("5s", "10s"); aspect_ratio ("16:9", "9:16", "1:1"); seed; image_url (source for image-to-video).
• MCP tools: search, find, generate, result, status, cancel, estimate_cost, models, upload.

Image Editing

Nano Banana 2 with an input image for inpainting, outpainting, or style transfer:

upload(file_path: "/path/to/image.png")
generate(model_name: "fal-ai/nano-banana-2", input: {
  "prompt": "same scene but in watercolor style",
  "image_url": "<uploaded_url>",
  "image_size": "landscape_16_9"
})

For non-MCP integrations (ElevenLabs, VideoDB), follow handlers/external-apis.md.

Common Mistakes

Using pure text-to-video when image-to-video would be more controllable; assuming fal.ai access covers ElevenLabs credentials (separate key).

Integration

• Called by: user directly, /ai-build, ai-video-editing (Layer 5 generated assets)
• Calls: fal.ai MCP, ElevenLabs API, VideoDB API
• See also: /ai-visual (composed visuals), /ai-slides (deck visuals), /ai-animation

Examples

/ai-media image hero for parallel agent planning blog

Iterates with nano-banana-2 (cheap), locks composition with seed, switches to nano-banana-pro for the production final, returns URL + cost.
