June 2026 FFMPEG API Team

Creating engaging videos for social media can be a tedious task, especially when you want to combine multiple images and audio files. FFMPEGAPI.net offers a robust and easy-to-use hosted REST API that simplifies this process. With the Image and Audio Merge API, developers can efficiently create MP4 videos from image/audio pairs, making it the best choice for social media video workflows.

What is the Image and Audio Merge API?

The Image and Audio Merge API allows developers to combine one or more image/audio pairs into a single MP4 video. Each image is displayed for the duration of its corresponding audio file, creating a smooth and engaging video experience.

This API supports both multi-pair operations through JSON requests and single pair operations using legacy strings, making it versatile for various use cases.

  • Create videos from multiple image/audio pairs.
  • Support for optional image transitions and zoom effects.
  • JSON requests for flexible and easy integrations.

How to Use the Image and Audio Merge API

To use the Image and Audio Merge API, developers need to send a POST request to the endpoint `/api/merge_image_audio` with the required parameters. The API accepts both JSON and multipart form data formats, allowing you to choose the best option for your application.

Key parameters include `image_urls`, `audio_urls`, and optional parameters such as `transition_effect`, `dimensions`, and `zoom_effect`.

  • image_urls: An array of image URLs for multi-pair requests.
  • audio_urls: An array of audio URLs matching the image count.
  • transition_effect: Optional transition effects like fade or slide.
import requests

url = 'https://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
}

response = requests.post(url, json=data)
print(response.json())
