June 2026 FFMPEG API Team

In today's digital landscape, creating engaging video content is more essential than ever. Whether you're building a SaaS application, developing a content pipeline, or working with AI agents, automating video creation can save time and enhance productivity. FFMPEGAPI.net offers a powerful hosted REST API that simplifies the process of merging images and audio into stunning videos. In this article, we will explore the 'Image and Audio Merge' endpoint and demonstrate how it can revolutionize your video processing workflows.

What is the Image and Audio Merge API?

The Image and Audio Merge API allows developers to create MP4 videos from pairs of images and audio files. Each image is displayed for the duration of its corresponding audio clip, making it a perfect tool for creating presentations, tutorials, or any content that requires visual storytelling.

  • Supports both single and multiple image/audio pairs.
  • Offers optional effects like transitions and slow zoom.
  • Allows customization of video dimensions.

How to Use the Image and Audio Merge API

Using the API is straightforward. You can make a POST request to the endpoint /api/merge_image_audio with the appropriate parameters. Here’s a breakdown of the key parameters you can use:

  • image_urls: An array of image URLs for multi-pair requests.
  • audio_urls: An array of audio URLs that correspond to the images.
  • transition_effect: Optional transition effects for image changes.
  • dimensions: Set custom output dimensions for the video.
  • zoom_effect: Control whether to apply a zoom effect while the audio plays.
curl -X POST https://www.ffmpegapi.net/api/merge_image_audio \
-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}'

Practical Example of Merging Images and Audio

Let's look at a practical example of how to use the Image and Audio Merge API to create a video from two images and their corresponding audio files. This example will demonstrate the ease of use and flexibility provided by FFMPEGAPI.net.

  • You can specify custom transition effects like 'fade' or 'slide'.
  • Define the duration of transitions to make your video more dynamic.
  • Set dimensions to ensure the video fits your desired layout.
import requests

url = 'https://www.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())
