June 2026 FFMPEG API Team

In today's digital landscape, automating video editing tasks can save developers a significant amount of time and resources. By leveraging the power of FFMPEGAPI.net, you can seamlessly merge images and audio to create professional-looking videos without the need for extensive server setup or FFmpeg management. In this article, we will explore how to use the Image and Audio Merge endpoint of FFMPEGAPI.net to automate your video editing workflows.

Understanding the Image and Audio Merge Endpoint

The Image and Audio Merge endpoint is designed to create an MP4 video by combining one or more pairs of images and audio files. Each image is displayed for the duration of its corresponding audio track, allowing for dynamic visual content synchronized with sound.

This powerful feature is particularly useful for developers working on automation, SaaS applications, content pipelines, or AI agents, as it simplifies the process of generating videos on-the-fly.

  • Supports multiple image/audio pairs.
  • Optional image transitions and zoom effects.
  • Simple JSON requests for quick integration.

Making Your First API Call

To get started, you'll want to make a POST request to the /api/merge_image_audio endpoint. The following parameters can be included in your request:

You can pass either arrays of image and audio URLs for multiple pairs or single image/audio pairs for backward compatibility.

  • image_urls: Array of image URLs.
  • audio_urls: Array of audio URLs.
  • transition_effect: Optional transitions for your images.
  • dimensions: Set specific video dimensions.

Advanced Features for Customization

FFMPEGAPI.net allows for a range of customization options to enhance your video output.

You can specify transition effects such as fade or wipe, adjust the duration of these transitions, and even apply zoom effects to each image.

  • Support for asynchronous processing, enabling large video jobs to be handled in the background.
  • Configurable transition effects including fade, slide, and more.
  • Set the zoom effect to make your videos more dynamic.

By utilizing the image and audio merge capabilities of FFMPEGAPI.net, developers can effortlessly automate video editing processes, create compelling visual content, and streamline workflows.
