Streamline Your Video Processing with FFMPEGAPI.net: Merging Images and Audio Made Easy

June 2026 FFMPEG API Team

In the world of video production, merging images and audio can significantly enhance the storytelling experience. Whether you are developing automation tools, SaaS applications, or content pipelines, FFMPEGAPI.net provides you with a hosted REST API to perform these tasks effortlessly without the hassle of server setup or managing FFmpeg infrastructure. In this article, we will explore how to use our API to merge images and audio into a single MP4 video.

Understanding the Image and Audio Merge API Endpoint

The Image and Audio Merge API allows you to create an MP4 video by combining one or more image/audio pairs. This means that each image is displayed for the duration of its corresponding audio file. You can send requests using image URLs and audio URLs for multiple pairs or utilize backward-compatible options for single pairs.

  • Create videos from multiple images and audio files.
  • Support for optional image transitions and zoom effects.
  • Simple JSON or multipart form data requests.

How to Make a Request to the Merge Endpoint

Using the POST method, you can send a request to the /api/merge_image_audio endpoint. The request can include several optional parameters, allowing you to customize the output video.

  • image_urls: An array of image URLs (for multi-pair requests).
  • audio_urls: An array of audio URLs (each paired with an image).
  • transition_effect: Choose from various transition effects.
  • dimensions: Specify the resolution of the output video.
import requests

url = 'https://www.ffmpegapi.net/api/merge_image_audio'
data = {
    '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=data)
print(response.json())
