Automate Video Creation with FFMPEGAPI.net's Image and Audio Merge

June 2026 FFMPEG API Team

In today's digital landscape, automation is key, especially when it comes to media processing. FFMPEGAPI.net offers a powerful hosted REST API for FFmpeg-powered video and audio processing, allowing developers to quickly and efficiently create videos from image and audio pairs. This article will guide you through the process of merging images and audio to create seamless MP4 videos using the Image and Audio Merge endpoint.

Understanding the Image and Audio Merge Endpoint

FFMPEGAPI.net provides an easy-to-use endpoint for merging images and audio, which is especially useful for developers automating content pipelines or building AI agents. The endpoint allows you to combine one or more image/audio pairs into a cohesive video.

The endpoint is accessed via a POST request to /api/merge_image_audio.

  • Supports both single and multiple image/audio pairs.
  • Optional image transitions and zoom effects can be added.
  • Returns a job ID for asynchronous processing, if desired.

Making a Request to Merge Images and Audio

To merge images and audio, you need to send a JSON request to the Image and Audio Merge endpoint. The request can include arrays of image and audio URLs for multiple pairs or individual image and audio strings for single pairs. Below is a JSON example for a multi-pair video creation.

{
  "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
}

Example cURL Request for Merging Images and Audio

If you prefer working with command-line tools, you can use cURL to make the same request. This is particularly useful for testing or integrating into automated scripts.

curl -X POST https://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
}'
