Merging Videos: The Video Merge Endpoint

One of the standout features of FFMPEGAPI.net is its Video Merge endpoint, which allows developers to concatenate multiple videos into a single MP4 file.

import requests

url = 'https://www.ffmpegapi.net/api/merge_videos'
data = {
    'video_urls': [
        'https://example.com/intro.mp4',
        'https://example.com/main.mp4'
    ],
    'dimensions': '1920x1080'
}
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer YOUR_API_KEY'}

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

The Video Merge API requires certain parameters to function effectively, allowing for customization according to your needs. Below are the parameters you can specify when making a request to the /api/merge_videos endpoint.

  • video_urls (required): An array of video URLs to merge.
