Understanding the Image and Audio Merge Endpoint

FFMPEGAPI.net's '/api/merge_image_audio' endpoint allows you to create an MP4 video by combining one or more images with corresponding audio tracks. Each image is displayed for the duration of its matching audio file, creating a seamless multimedia experience. This API is particularly useful for automating content pipelines and integrating into SaaS applications.

  • Supports multiple image/audio pairs.
  • Allows for custom transitions and zoom effects.
  • Easy integration with API-key authentication.

Making Your First API Call

To get started with the image and audio merge functionality, you can send a POST request to the '/api/merge_image_audio' endpoint. The request can be made in either JSON format or multipart/form-data, depending on your preference.

  • Use 'image_urls' and 'audio_urls' for multiple pairs.
  • Use 'image' and 'audio' for a single pair.
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_duration': 0.75,
    'dimensions': '1280x720',
    'zoom_effect': true,
    'async': false
}

response = requests.post(url, json=data)
print(response.json())
