This article explores how to use the Image and Audio Merge endpoint to create MP4 videos from image/audio pairs seamlessly.

Getting Started with the Image and Audio Merge Endpoint

FFMPEGAPI.net offers an easy-to-use endpoint for merging images and audio into an MP4 video. By sending a POST request to the /api/merge_image_audio path, you can create videos that are tailored to your specific needs. Whether you need to combine multiple images and audio files or just a single pair, this API simplifies the process.

  • No server management required.
  • API-key authentication for secure access.
  • Supports multiple image/audio pairs.

Parameters for Merging Images and Audio

The Image and Audio Merge API accepts several parameters that allow customization of the final video. Here's a brief overview of the key parameters you can use in your JSON requests:

  • image_urls: An array of image URLs for multi-pair requests.
