In the world of multimedia, merging images and audio to create compelling video content is essential. Whether you're building a content pipeline, automating video production, or developing SaaS applications, having a reliable tool at your fingertips is crucial. FFMPEGAPI.net provides hosted REST API solutions that simplify the video processing workflow, allowing developers to focus on their core projects without the hassle of server setup or FFmpeg maintenance. This article will explore how to use the Image and Audio Merge endpoint to create MP4 videos effortlessly.

Understanding the Image and Audio Merge Endpoint

FFMPEGAPI.net offers a powerful endpoint to merge images and audio seamlessly. The '/api/merge_image_audio' endpoint enables you to create MP4 videos from one or more image/audio pairs. This is particularly useful for generating content such as presentations, tutorials, and marketing videos.

  • Combine multiple images with their corresponding audio.
  • Control image display duration by audio length.
  • Customize transitions and effects to enhance video quality.

Making a Request to the Merge Endpoint

To use the merge functionality, send a POST request to the '/api/merge_image_audio' endpoint. The request can be made using JSON or multipart form-data. Here’s how you can structure your request to create an engaging video.

  • Use 'image_urls' and 'audio_urls' arrays for multiple pairs.
  • Optional parameters include transition effects and output dimensions.
import requests

url = 'https://www.ffmpegapi.net/api/merge_image_audio'

payload = {
    '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=payload)
print(response.json())
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
}'
