In the evolving landscape of digital content, automating video creation processes has become essential for developers and businesses alike. FFMPEGAPI.net offers a powerful hosted REST API that allows you to merge images and audio seamlessly. This article will explore the Image and Audio Merge endpoint, detailing how you can utilize it to enhance your video automation workflows.

What is the Image and Audio Merge Endpoint?

The Image and Audio Merge endpoint is a POST method that lets you combine image and audio files to produce an MP4 video. This endpoint provides an intuitive way to create videos where each image is displayed for the duration of its corresponding audio file.

FFMPEGAPI.net makes this process straightforward. Developers no longer need to manage complex FFmpeg infrastructure or server setups, allowing them to focus on building their applications.

  • Combines multiple images and audio files.
  • Supports image transitions and zoom effects.
  • API-key based authentication ensures secure usage.

How to Use the Image and Audio Merge Endpoint

To leverage the Image and Audio Merge functionality, you'll send a JSON request that includes the URLs of your images and audio files. The API supports both multi-pair requests and legacy single pairs, allowing flexibility based on your needs.

Here’s a breakdown of the parameters you can use:

  • image_urls: Array of image URLs for multi-pair requests.
  • audio_urls: Array of audio URLs that correspond to each image.
  • transition_effect: Optional effects like fade, slide, etc.
  • zoom_effect: Specify if you want a slow zoom on images.
