Creating engaging videos from images and audio can enhance your content delivery. With FFMPEGAPI.net, developers can leverage a powerful hosted REST API for seamless video processing without the hassle of server management or FFmpeg infrastructure. This article explores how to use the Image and Audio Merge endpoint to easily generate MP4 videos from image/audio pairs.

What is the Image and Audio Merge API?

The Image and Audio Merge API provided by FFMPEGAPI.net allows developers to create MP4 videos from one or more image/audio pairs. This functionality is invaluable for applications in content delivery, automation, and SaaS platforms.

  • Combine multiple images and audio tracks.
  • Set custom transition effects between images.
  • Control image display time via audio duration.

How to Use the API

To use the Image and Audio Merge API, you need to send a POST request to the endpoint `/api/merge_image_audio`. Developers can easily construct JSON requests using the required parameters.

  • Use `image_urls` and `audio_urls` for multi-pair videos.
  • Specify optional effects such as transitions and zoom.
  • Choose between synchronous and asynchronous processing.
import requests

url = 'https://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())
