In today's digital landscape, creating multimedia content quickly and efficiently is crucial for developers, SaaS applications, and content pipelines. FFMPEGAPI.net offers a fast and reliable solution for merging images and audio into captivating videos through its hosted REST API. This blog explores how to utilize the Image and Audio Merge endpoint to streamline your media processing workflow.

What is the Image and Audio Merge Endpoint?

The Image and Audio Merge endpoint allows you to create MP4 videos from pairs of images and audio files. Each image is displayed for the duration of its corresponding audio track, enabling seamless transitions between content. This is particularly useful for developers looking to automate video creation for presentations, tutorials, or promotional content.

  • Combines multiple image/audio pairs.
  • Supports automatic image transitions.
  • Offers zoom effects on images while audio plays.

How to Use the Merge Endpoint

To interact with the merge functionality, you'll make a POST request to the endpoint /api/merge_image_audio. The request can be made using JSON to include arrays of image URLs and audio URLs. Additionally, you can specify optional parameters such as transition effects and desired output dimensions.

  • POST method required.
  • Supports application/json or multipart/form-data.
curl -X POST https://ffmpegapi.net/api/merge_image_audio \n-H "Content-Type: application/json" \n-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}'
