As a developer, integrating multimedia capabilities such as merging images and audio can be a daunting task. Fortunately, FFMPEGAPI.net provides an effortless hosted solution with its Image and Audio Merge API. This article explores how to leverage this powerful tool to create engaging video content without the hassle of server setup or management.

Overview of the Image and Audio Merge API

The Image and Audio Merge API allows you to create MP4 videos from image and audio pairs easily. Each image can be displayed for the duration of its corresponding audio, providing a straightforward way to present visual and auditory content together.

  • Combines multiple image/audio pairs for dynamic video creation.
  • Supports JSON requests with arrays for multiple files or backward-compatible single file uploads.
  • Offers optional transition effects and zoom capabilities for enhanced visual appeal.

How to Use the Image and Audio Merge Endpoint

To utilize the Image and Audio Merge API, you'll need to make a POST request to the /api/merge_image_audio endpoint. The requests can be made using JSON for multiple pairs or via multipart form data for single pairs.

Here’s a breakdown of the key parameters you can use in your request:

  • image_urls: An array of image URLs for multiple images.
  • audio_urls: An array of audio URLs; each audio duration matches its corresponding image.
  • transition_effect: Optional effects such as fade or slide to enhance transitions between images.
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',

    'transition_effect': 'fade',
    'transition_duration': 0.75,
