June 2026 FFMPEG API Team

In today's fast-paced digital environment, developers are constantly seeking efficient tools to enhance their content production workflows. FFMPEGAPI.net offers a robust REST API that simplifies video and audio processing without the need for server setup or FFmpeg infrastructure management. This article focuses on the 'Image and Audio Merge' feature, enabling you to create engaging MP4 videos by combining images and audio effortlessly.

Getting Started with Image and Audio Merge

FFMPEGAPI.net provides a straightforward endpoint for merging images with audio files. By using the '/api/merge_image_audio' endpoint, developers can transform multiple image and audio pairs into a single MP4 video.

This feature is particularly beneficial for creating multimedia presentations, tutorials, or even video content for social media, allowing each image to be displayed for the duration of its corresponding audio clip.

  • Easily merge images and audio into MP4 videos.
  • No server management or complex setup required.
  • Customizable transitions and zoom effects available.

How to Use the Merge Endpoint

To use the merge endpoint, you need to send a POST request with the necessary parameters. The API supports both JSON and multipart form data formats. You can provide either arrays of image and audio URLs for multiple pairs or single image/audio strings for one pair.

  • Use 'image_urls' and 'audio_urls' for multi-pair videos.
  • Use 'image' and 'audio' for single pair videos.
import requests

url = 'https://ffmpegapi.net/api/merge_image_audio'
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer YOUR_API_KEY'}

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, headers=headers, json=data)
print(response.json())

Parameters for Customization
