June 2026 FFMPEG API Team

In today’s digital landscape, the demand for dynamic video content is ever-increasing. Developers are constantly looking for efficient ways to generate videos programmatically. FFMPEGAPI.net offers a robust hosted solution for merging images and audio, allowing you to edit videos without the hassle of server management. This guide will walk you through using the Image and Audio Merge API endpoint effectively.

What is the Image and Audio Merge API?

The Image and Audio Merge API is a powerful endpoint provided by FFMPEGAPI.net, enabling developers to create MP4 videos from image and audio pairs with ease. You can combine multiple image/audio pairs, where each image is displayed for the duration of its corresponding audio file.

  • Supports multi-pair combinations with JSON request formats.
  • Optional effects including image transitions and slow zoom.
  • No server setup required—fully managed by FFMPEGAPI.net.

API Endpoint Details

To use the Image and Audio Merge endpoint, you will make a POST request to the following path: `/api/merge_image_audio`. The request can accept either JSON or multipart/form-data, providing flexibility based on your implementation needs.

  • Method: POST
  • Content Types: application/json or multipart/form-data
  • Key parameters include image_urls, audio_urls, and optional transition effects.
curl -X POST https://www.ffmpegapi.net/api/merge_image_audio \
-H 'Content-Type: application/json' \
-d '{"image_urls": ["https://example.com/intro.jpg", "https://example.com/chapter-1.jpg"], "audio_urls": ["https://example.com/intro.mp3", "https://example.com/chapter-1.mp3"], "transition_effect": "fade", "transition_duration": 0.75, "dimensions": "1280x720", "zoom_effect": true, "async": false}'

Practical Example of Merging Images and Audio

To demonstrate the capabilities of this API, let’s consider an example where we want to create a video that features a series of images synchronized with their respective audio files.

  • Image URLs: ["https://example.com/intro.jpg", "https://example.com/chapter-1.jpg"]
  • Audio URLs: ["https://example.com/intro.mp3", "https://example.com/chapter-1.mp3"]
  • You can customize transitions and zoom effects to enhance the visual appeal.
import requests

url = 'https://www.ffmpegapi.net/api/merge_image_audio'
payload = {
    'image_urls': [
        'https://example.com/intro.jpg',
        'https://example.com/chapter-1.jpg'
    ],
    'audio_urls': [
        'https://example.com/intro.mp3',
        'https://example.com/chapter-1.mp3'
    ],
    'transition_effect': 'fade',
    'transition_duration': 0.75,
    'dimensions': '1280x720',
    'zoom_effect': True,
    'async': False
}

response = requests.post(url, json=payload)
print(response.json())
