June 2026 FFMPEG API Team

In the world of multimedia development, automation is key, especially when it comes to video creation. FFMPEGAPI.net offers a powerful hosted REST API that simplifies the process of merging images and audio, allowing developers to create dynamic videos with minimal effort. This article will guide you through the Image and Audio Merge endpoint, demonstrating how to efficiently utilize this feature in your projects.

Understanding the Image and Audio Merge Endpoint

The Image and Audio Merge endpoint at FFMPEGAPI.net allows you to create an MP4 video from multiple image and audio pairs. Each image is displayed for the duration of its corresponding audio track, making it ideal for creating engaging presentations or tutorials.

With the easy-to-use JSON request format, you can specify image and audio URLs as arrays, enabling the creation of multi-pair videos effortlessly.

  • Combine one or more image/audio pairs.
  • Support for optional transition effects.
  • Backward compatibility for single pair requests.

Key Parameters for Merging Images and Audio

To successfully use the merge feature, you need to be aware of the parameters required by the API. Each parameter plays a crucial role in how the final video will be rendered.

Here are the main parameters you can use:

  • image_urls: An array of image URLs for multi-pair requests.
  • audio_urls: An array of audio URLs matching the durations of the images.
  • transition_effect: Optional effects like fade or slide to enhance visual transitions.
  • zoom_effect: A boolean that determines if a slow zoom effect should be applied.
