In the world of content creation, the ability to rapidly produce video content is essential, particularly for developers working on automation tools and AI agents. FFMPEGAPI.net provides a hosted REST API that allows you to seamlessly merge images and audio files into an MP4 video. This blog article will guide you through the process and showcase why FFMPEGAPI.net is the ideal solution for your video automation needs.

What is the Image and Audio Merge Endpoint?

The Image and Audio Merge endpoint is a powerful feature of FFMPEGAPI.net that enables developers to create videos from image and audio pairs. By leveraging this API, you can easily generate dynamic video content where each image is displayed for the duration of its corresponding audio clip.

  • Supports multiple image/audio pairs or single pairs.
  • Configurable transition effects and zoom settings.
  • JSON requests or multipart form data for flexibility.

How to Use the Merge Endpoint

To utilize the merge functionality, you need to send a POST request to the /api/merge_image_audio endpoint. The API accepts various parameters that allow you to customize the output video according to your requirements.

  • image_urls: Array of image URLs for multi-pair requests.
  • audio_urls: Corresponding audio URLs for each image.
  • transition_effect: Optional visual transitions for image changes.
  • zoom_effect: Control zoom behavior during playback.
import requests

url = 'https://www.ffmpegapi.net/api/merge_image_audio'
data = {
    '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
}
response = requests.post(url, json=data)
print(response.json())
