Workflow Examples

Portrait Animation Pipeline

// 1. Generate a portrait image
const portrait = await fal.subscribe("fal-ai/flux/dev", {
  input: {
    prompt: "Professional headshot of a business woman, neutral expression, studio lighting",
    image_size: "portrait_4_3"
  }
});

// 2. Animate the portrait
const video = await fal.subscribe("fal-ai/kling-video/v2.5/pro/image-to-video", {
  input: {
    prompt: "She slowly turns her head, makes eye contact with camera, and gives a warm professional smile",
    image_url: portrait.images[0].url,
    duration: "5",
    aspect_ratio: "16:9"
  }
});

console.log(video.video.url);

Product Showcase

// Animate product image
const result = await fal.subscribe("fal-ai/minimax-video/image-to-video", {
  input: {
    prompt: "The camera slowly rotates around the product, highlighting details, studio lighting",
    image_url: "https://example.com/product-shot.jpg",
    prompt_optimizer: true
  }
});

Nature Scene

// Create ambient nature video
const result = await fal.subscribe("fal-ai/luma-dream-machine", {
  input: {
    prompt: "Gentle breeze moves through the grass, clouds drift slowly overhead, peaceful ambient motion",
    image_url: "https://example.com/landscape.jpg",
    aspect_ratio: "16:9",
    loop: true  // Perfect for background video
  }
});

Fast Preview Workflow

// Quick preview with faster model
const preview = await fal.subscribe("fal-ai/stable-video-diffusion", {
  input: {
    image_url: sourceImage,
    motion_bucket_id: 100
  }
});

console.log("Preview:", preview.video.url);

// If satisfied, use higher quality model
const final = await fal.subscribe("fal-ai/kling-video/v2.6/pro/image-to-video", {
  input: {
    prompt: "Refined motion description based on preview",
    image_url: sourceImage,
    duration: "5"
  }
});

Best Practices

Image Preparation

1. High Resolution: Use high-quality source images
2. Clear Subject: Ensure main subject is clearly visible
3. Proper Framing: Leave room for motion
4. Consistent Lighting: Avoid harsh shadows

Prompt Tips

1. Describe the motion, not the static scene
2. Be specific about direction (left, right, forward)
3. Include speed (slowly, quickly, gradually)
4. Match motion to image content
