In today's fast-paced digital landscape, automation is key to efficient workflows, especially for developers working with video content. FFMPEGAPI.net offers a robust hosted REST API for FFmpeg-powered video and audio processing, eliminating the need for server setup. This article explores how the Image and Audio Merge endpoint enables seamless video creation, perfect for content pipelines and AI agents.

Understanding the Image and Audio Merge Endpoint

The Image and Audio Merge endpoint allows you to create an MP4 video by combining image and audio pairs. This functionality is particularly useful for automating video creation, where images can be displayed sequentially with corresponding audio. Whether you're building a presentation, a marketing video, or content for social media, this API enables you to streamline the process.

  • Supports both single pairs and multi-pair combinations of images and audio.
  • Offers optional transition effects and a slow zoom feature for enhanced visuals.
  • JSON and multipart/form-data request support for flexible integration.

How to Use the Merge Image and Audio Endpoint

To utilize the merge functionality, you can send a POST request to the endpoint: `/api/merge_image_audio`. You can specify parameters such as `image_urls`, `audio_urls`, transition effects, and even output dimensions.

  • Image URLs must correspond with audio URLs for proper pairing.
  • Optional parameters include transition effects, transition duration, and zoom effects.
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, "async": false}'
