Creating dynamic videos from images and audio files has never been easier, thanks to FFMPEGAPI.net. Our hosted REST API allows developers to merge images and audio seamlessly, making it the perfect solution for automation, SaaS applications, and content pipelines without the hassle of server management.

Why Use FFMPEGAPI.net for Image and Audio Merging?

FFMPEGAPI.net provides a cloud-based solution for video processing that eliminates the need for local FFmpeg installations and infrastructure management. With our API, developers can focus on building applications rather than managing complex video processing tasks.

  • No server setup required, saving time and resources.
  • API-key authentication ensures secure and efficient workflows.
  • Ideal for integration with existing applications and automation.

Understanding the Image and Audio Merge API Endpoint

The 'Image and Audio Merge' endpoint allows you to create MP4 videos by combining image and audio pairs. Each image is displayed for the duration of its corresponding audio file, enabling you to craft engaging narratives through visual and audio storytelling.

The endpoint path is POST /api/merge_image_audio. You can send your requests in either JSON or multipart/form-data format.

  • Supports multiple image/audio pairs through arrays.
  • Optional transitions and zoom effects enhance video quality.
  • Asynchronous processing available for large tasks.
import requests

url = 'https://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())
