June 2026 FFMPEG API Team

Creating engaging video content from images and audio has never been easier. With FFMPEGAPI.net's Image and Audio Merge endpoint, developers can effortlessly generate MP4 videos that pair images with corresponding audio tracks. This hosted REST API simplifies complex media processes without requiring server setup or intricate FFmpeg management.

What is the Image and Audio Merge Endpoint?

The Image and Audio Merge endpoint allows developers to combine one or more image/audio pairs into a cohesive MP4 video. Each image is displayed for the duration of its associated audio track, creating a dynamic viewing experience. This functionality is essential for developers looking to enhance SaaS applications, automate video creation, or build content pipelines.

  • Supports multiple image/audio pairs.
  • Optional transition effects for a polished finish.
  • Default slow zoom effect on images enhances visual appeal.

How to Use the Image and Audio Merge Endpoint

To make a request to the Image and Audio Merge endpoint, you'll use a POST method at the endpoint path '/api/merge_image_audio'. The request can be formatted in JSON or multipart/form-data, depending on your needs.

  • Required parameters include image_urls and audio_urls for multi-pair requests.
  • Single pairs can be specified using backward-compatible image and audio fields.
  • Transition effects and dimensions can be customized for each video.
import requests

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

payload = {
    '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,
    'dimensions': '1280x720',
    'zoom_effect': true,

}
