Image-to-Video with Seedance

import wavespeed
import base64
from pathlib import Path

def image_to_video(image_path: str, animation_prompt: str) -> str:
    """Convert a static image to an animated video"""

    client = wavespeed.Client(api_key="your-api-key")

    # Read and encode image
    image_data = Path(image_path).read_bytes()
    image_base64 = base64.b64encode(image_data).decode('utf-8')

    # Generate video from image
    video = client.video.generate(
        model="seedance-v3",
        image=image_base64,
        prompt=animation_prompt,
        duration=4,
        motion_strength=0.8  # Control how much motion to add
    )

    return video.url

# Example: Animate character artwork
video_url = image_to_video(
    image_path="character_design.png",
    animation_prompt="The character smiles and waves at the camera"
)

print(f"Animated video: {video_url}")

Advanced: Quality Comparison Tool

const wavespeed = require('wavespeed-sdk');
const fs = require('fs/promises');

/**
 * Generate the same video across multiple models for quality comparison
 */
async function compareModels(prompt, models) {
  const client = new wavespeed.Client({ apiKey: process.env.WAVESPEED_API_KEY });

  const results = await Promise.allSettled(
    models.map(async (model) => {
      const startTime = Date.now();

      const video = await client.video.generate({
        model,
        prompt,
        duration: 5,
        aspectRatio: '16:9'
      });

      const generationTime = Date.now() - startTime;

      return {
        model,
        url: video.url,
        thumbnail: video.thumbnail,
        generationTime,
        metadata: video.metadata
      };
    })
  );

  // Format results
  const comparison = results.map((result, i) => {
    if (result.status === 'fulfilled') {
      return result.value;
    } else {
      return {
        model: models[i],
        error: result.reason.message
      };
    }
  });

  // Save comparison report
  await fs.writeFile(
    'comparison-report.json',
    JSON.stringify(comparison, null, 2)
  );

  return comparison;
}

// Compare top models
const comparison = await compareModels(
  'A professional product shot of a luxury watch rotating slowly',
  ['kling-v1', 'runway-gen3', 'luma-dream']
);

console.log('Comparison complete:', comparison);

Best Practices for Video Generation APIs

1. Optimize Your Prompts

Be specific and descriptive:

// Poor prompt
"A car"

// Better prompt
"A sleek red sports car driving along a coastal highway at sunset, cinematic angle"

// Best prompt
"A sleek red Ferrari sports car driving along a winding coastal highway at golden hour, shot from a helicopter following alongside, dramatic cliffs and ocean in background, cinematic color grading"

2. Choose the Right Model for Your Use Case

def select_model(use_case: str) -> str:
    """Select the best model based on use case"""

    model_map = {
        'high_quality': 'kling-v1',          # Best quality, reasonable speed
        'fast_generation': 'hailuo-v1',       # Fastest, good enough quality
        'professional': 'runway-gen3',        # Professional features
        'product_demo': 'luma-dream',         # Best for 3D/products
        'image_animation': 'seedance-v3',     # Image-to-video
        'cost_effective': 'pika-v1'           # Budget-friendly
    }

    return model_map.get(use_case, 'kling-v1')

# Usage
model = select_model('high_quality')

3. Implement Proper Error Handling

async function robustVideoGeneration(prompt, options = {}) {
  const maxRetries = 3;
  const retryDelay = 2000;

  for (let i = 0; i < maxRetries; i++) {
    try {
      const video = await client.video.generate({
        prompt,
        ...options,
        timeout: 120000  // 2 minute timeout
      });

      return video;

    } catch (error) {
      console.error(`Attempt ${i + 1} failed:`, error.message);

      // Don't retry on validation errors
      if (error.code === 'INVALID_PROMPT') {
        throw error;
      }

      // Retry on rate limits or server errors
      if (i < maxRetries - 1) {
        await new Promise(resolve => setTimeout(resolve, retryDelay * (i + 1)));
      } else {
        throw new Error(`Failed after ${maxRetries} attempts: ${error.message}`);
      }
    }
  }
}

4. Monitor Costs

class CostTracker:
    def __init__(self):
        self.costs = {
            'kling-v1': 0.08,
            'runway-gen3': 0.10,
            'hailuo-v1': 0.03,
            'luma-dream': 0.06,
            'seedance-v3': 0.07,
            'pika-v1': 0.03
        }
        self.total_spent = 0
        self.generations = []

    def estimate_cost(self, model: str, count: int = 1) -> float:
        return self.costs.get(model, 0.05) * count

    def track_generation(self, model: str):
        cost = self.costs.get(model, 0.05)
        self.total_spent += cost
        self.generations.append({
            'model': model,
            'cost': cost,
            'timestamp': time.time()
        })

    def get_report(self) -> dict:
        return {
            'total_spent': self.total_spent,
            'total_generations': len(self.generations),
            'average_cost': self.total_spent / len(self.generations) if self.generations else 0
        }

# Usage
tracker = CostTracker()
print(f"Estimated cost: ${tracker.estimate_cost('kling-v1', count=10)}")

5. Cache and Reuse Content

const crypto = require('crypto');
const cache = new Map();

function generateCacheKey(prompt, options) {
  const data = JSON.stringify({ prompt, ...options });
  return crypto.createHash('md5').update(data).digest('hex');
}

async function cachedVideoGeneration(prompt, options = {}) {
  const cacheKey = generateCacheKey(prompt, options);

  // Check cache first
  if (cache.has(cacheKey)) {
    console.log('Returning cached video');
    return cache.get(cacheKey);
  }

  // Generate new video
  const video = await client.video.generate({
    prompt,
    ...options
  });

  // Cache result
  cache.set(cacheKey, video);

  return video;
}

FAQ

2. Choose the right model: Use Kling or Runway for highest quality
3. Specify style: Add terms like “cinematic,” “professional,” “4K”
4. Use reference images: When available (e.g., Seedance)
5. Iterate and refine: Generate multiple variations

Q: What are the rate limits?

A: Rate limits vary by provider and tier:

• Free tiers: 5-10 videos per day
• Paid tiers: 100-1000+ videos per day
• Enterprise: Custom limits

WaveSpeedAI offers generous rate limits that scale with your usage tier.

Q: Can I generate videos from images?

A: Yes, several providers offer image-to-video:

• Seedance (via WaveSpeedAI): Excellent image-to-video quality
• Runway Gen-3: Image and video inputs
• Pika Labs: Image animation features

This is useful for animating concept art, product renders, or storyboards.

Q: How do I handle failed generations?

A: Best practices:

1. Implement retries: Automatic retry with exponential backoff
2. Use webhooks: For async generation, get notified of completion/failure
3. Validate prompts: Check for restricted content before generation
4. Monitor status: Poll generation status for long-running jobs
5. Log failures: Track failure patterns to improve prompts

Q: Are there content restrictions?

A: Yes, all providers restrict:

• Violence and gore
• Adult content
• Illegal activities
• Copyrighted characters/brands
• Deepfakes of real people

Review each provider’s acceptable use policy.
