June 2026 FFMPEG API Team

In today's digital landscape, automation is key to efficient workflows, especially when it comes to video editing. FFMPEGAPI.net offers a powerful hosted REST API that makes it easy for developers to merge images with audio, creating engaging video content without the hassle of server management. This article will guide you through the process of using the Image and Audio Merge endpoint to enhance your projects with automated video editing.

Understanding the Image and Audio Merge Endpoint

The Image and Audio Merge endpoint allows you to create an MP4 video from image/audio pairs with minimal setup. You can combine multiple images and audio files, where each image displays for the duration of its corresponding audio track. This is particularly useful for creating presentations, educational content, or marketing videos.

  • Supports both single and multiple image/audio pairs.
  • Provides optional transition effects for a polished video.
  • Allows for dimensions and zoom effects to enhance visual appeal.

How to Use the Endpoint

To utilize this feature, you send a POST request to the /api/merge_image_audio endpoint. The request can either be in JSON format or multipart/form-data. Below are the required and optional parameters you can use:

  • image_urls (array): List of image URLs for multi-pair requests.
  • audio_urls (array): List of audio URLs for multi-pair requests.
  • image (string): Single image URL for legacy support.
  • audio (string): Single audio URL for legacy support.
  • transition_effect (string): Defines any transition effect between images.
  • transition_duration (number): Duration of the transition effect.
  • dimensions (string): Set the output video dimensions.
  • zoom_effect (boolean): Enable or disable the slow zoom effect.
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, headers={'Authorization': 'Bearer YOUR_API_KEY'})
print(response.json())
curl -X POST https://ffmpegapi.net/api/merge_image_audio \
-H "Authorization: Bearer YOUR_API_KEY" \
-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}'
