June 2026 FFMPEG API Team

The demand for automated video content is on the rise, especially in the realms of AI and SaaS applications. FFMPEGAPI.net provides a hassle-free solution for developers looking to merge images and audio into engaging MP4 videos. With a simple API endpoint, you can create stunning video presentations with minimal effort.

Overview of the Image and Audio Merge API

The Image and Audio Merge API endpoint at FFMPEGAPI.net allows you to create MP4 videos from pairs of images and audio files. This functionality is especially useful for developers who want to automate video content creation as part of their workflows.

By leveraging this hosted REST API, developers can avoid the complexities of managing their own FFmpeg infrastructure, ultimately saving time and resources.

  • No server setup required.
  • API-key authentication for secure access.
  • Ideal for content pipelines, automation, and AI agents.

How to Use the Merge API Endpoint

The endpoint for merging images and audio is straightforward: POST /api/merge_image_audio. The request can take multiple parameters, including arrays for image and audio URLs, as well as options for transition effects and dimensions.

For multi-pair videos, JSON requests should contain image_urls and audio_urls arrays of equal length. If you only need to merge a single image and audio, you can use the backward-compatible image and audio parameters.

  • Supports multi-pair videos through image_urls and audio_urls.
  • Customizable transition effects and dimensions.
  • Asynchronous processing option available.
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
}

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

print(response.json())

  • Set dimensions for the output video.
  • Control the zoom effect of images.
