Understanding the Image and Audio Merge Endpoint

The Image and Audio Merge endpoint allows you to create an MP4 video from one or more pairs of images and audio files. This functionality is especially useful for creating video content for presentations, tutorials, and creative projects.

The endpoint supports various parameters, including optional transition effects and a default slow zoom effect that enhances viewer engagement.

Creating a Video with CURL

Using CURL, you can easily send a request to the merge endpoint. Below is an example that combines two images and their respective audio files into a single video.

This request showcases how to include optional parameters like transition effects and dimensions.

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}'
