Understanding the Image and Audio Merge API

The Image and Audio Merge API allows developers to create engaging videos by combining one or multiple image/audio pairs. The API is designed for automation, content pipelines, and SaaS applications, making it a versatile tool for developers.

  • Merge multiple images with corresponding audio tracks.

How to Use the API Endpoint

To create a video, you will use a POST request to the endpoint: /api/merge_image_audio. The request can include arrays for multiple image and audio URLs or single image/audio pairs in a backward-compatible format.

  • Request content type can be either application/json or multipart/form-data.
  • Parameters like transition effects, zoom effects, and output dimensions can be specified.
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,
    'async': False
}
response = requests.post(url, json=data)
print(response.json())
