API Integration Guide

Step 1: Basic Conversion

javascript
const convertToGIF = async (videoUrl) => {
  try {
    const response = await fetch('https://eranol.com/api/v1/convert/gif', {
      method: 'POST',
      headers: {
        'x-api-key': process.env.ERANOL_API_KEY,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        input_url: videoUrl
      })
    });

    if (!response.ok) {
      throw new Error(`API Error: ${response.statusText}`);
    }

    const result = await response.json();
    return result;
  } catch (error) {
    console.error('GIF conversion failed:', error);
    throw error;
  }
};

// Convert entire video to GIF
const job = await convertToGIF('https://example.com/video.mp4');

Step 2: Extract Specific Clip

javascript
const extractClipAsGIF = async (videoUrl, startTime, duration) => {
  const response = await fetch('https://eranol.com/api/v1/convert/gif', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.ERANOL_API_KEY,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      input_url: videoUrl,
      start_time: startTime,
      duration: duration,
      width: 480,
      fps: 15
    })
  });

  return await response.json();
};

// Extract 5 seconds starting at 10s mark
const gif = await extractClipAsGIF('https://example.com/video.mp4', 10, 5);

Step 3: Optimize for File Size

javascript
const createOptimizedGIF = async (videoUrl, options = {}) => {
  const response = await fetch('https://eranol.com/api/v1/convert/gif', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.ERANOL_API_KEY,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      input_url: videoUrl,
      start_time: options.startTime || 0,
      duration: options.duration || 3,
      width: options.width || 480,
      fps: options.fps || 12,
      colors: options.colors || 128,
      optimize: true,
      lossy: 80
    })
  });

  return await response.json();
};

// Create small, optimized GIF
const smallGIF = await createOptimizedGIF('https://example.com/video.mp4', {
  width: 320,
  fps: 10,
  colors: 64,
  duration: 2
});

Optimization Techniques

File Size Optimization

Setting	Small	Medium	Large
Width	320px	480px	640px
FPS	10	15	24
Colors	64	128	256
Duration	2s	3s	5s
File Size	~500KB	~2MB	~5MB

Quality vs Size Trade-offs

javascript
const qualityPresets = {
  social: {
    width: 480,
    fps: 15,
    colors: 128,
    optimize: true,
    lossy: 80
  },
  highQuality: {
    width: 640,
    fps: 24,
    colors: 256,
    optimize: true,
    lossy: 60
  },
  thumbnail: {
    width: 200,
    fps: 10,
    colors: 64,
    optimize: true,
    lossy: 90
  }
};

const createGIFWithPreset = async (videoUrl, preset) => {
  const settings = qualityPresets[preset];
  
  const response = await fetch('https://eranol.com/api/v1/convert/gif', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.ERANOL_API_KEY,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      input_url: videoUrl,
      ...settings
    })
  });

  return await response.json();
};

Best Practices

1. Keep It Short

javascript
// Good: 2-5 seconds
const shortGIF = await convertToGIF(videoUrl, {
  duration: 3
});

// Bad: 30 seconds (huge file)
const longGIF = await convertToGIF(videoUrl, {
  duration: 30 // File will be 20MB+
});

2. Reduce Frame Rate

javascript
// Smooth but large
const smoothGIF = await convertToGIF(videoUrl, {
  fps: 30 // 5MB
});

// Acceptable and smaller
const optimizedGIF = await convertToGIF(videoUrl, {
  fps: 15 // 2MB
});

3. Limit Colors

javascript
// Maximum quality
const fullColorGIF = await convertToGIF(videoUrl, {
  colors: 256
});

// Good balance
const balancedGIF = await convertToGIF(videoUrl, {
  colors: 128 // Half the size, minimal quality loss
});

4. Add Captions

javascript
const addCaptionToGIF = async (videoUrl, caption) => {
  const response = await fetch('https://eranol.com/api/v1/convert/gif', {
    method: 'POST',
    headers: {
      'x-api-key': process.env.ERANOL_API_KEY,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      input_url: videoUrl,
      duration: 3,
      text: caption,
      text_position: 'bottom',
      text_size: 24,
      text_color: 'white',
      text_background: 'rgba(0,0,0,0.7)'
    })
  });

  return await response.json();
};

Real-World Implementation

javascript
class GIFConverter {
  constructor(apiKey) {
    this.apiKey = apiKey;
    this.baseUrl = 'https://eranol.com/api/v1';
  }

  async convertToGIF(videoUrl, options = {}) {
    const defaultOptions = {
      width: 480,
      fps: 15,
      colors: 128,
      optimize: true,
      duration: 3
    };

    const finalOptions = { ...defaultOptions, ...options };

    const response = await fetch(`${this.baseUrl}/convert/gif`, {
      method: 'POST',
      headers: {
        'x-api-key': this.apiKey,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        input_url: videoUrl,
        ...finalOptions
      })
    });

    if (!response.ok) {
      throw new Error(`API Error: ${response.statusText}`);
    }

    const job = await response.json();
    return await this.waitForCompletion(job.job_id);
  }

  async waitForCompletion(jobId) {
    const maxAttempts = 60;
    
    for (let i = 0; i < maxAttempts; i++) {
      const response = await fetch(`${this.baseUrl}/status/${jobId}`, {
        headers: { 'x-api-key': this.apiKey }
      });

      const status = await response.json();

      if (status.state === 'completed') {
        return status.output_url;
      } else if (status.state === 'failed') {
        throw new Error(`Conversion failed: ${status.error}`);
      }

      await this.sleep(3000);
    }

    throw new Error('Conversion timeout');
  }

  sleep(ms) {
    return new Promise(resolve => setTimeout(resolve, ms));
  }
}

// Usage
const converter = new GIFConverter(process.env.ERANOL_API_KEY);

// Create optimized GIF
const gifUrl = await converter.convertToGIF('https://example.com/video.mp4', {
  start_time: 5,
  duration: 3,
  width: 480,
  fps: 15
});

console.log('GIF ready:', gifUrl);

Cost Optimization

Duration Impact

Duration	File Size	Cost
1 second	~500KB	$0.05
3 seconds	~2MB	$0.08
5 seconds	~4MB	$0.12
10 seconds	~10MB	$0.20

Recommendation: Keep GIFs under 5 seconds for best balance.

Troubleshooting
