Understanding the Video Merge Endpoint

The Video Merge endpoint is designed for concatenating multiple video files into a single MP4 file. This endpoint supports various features such as audio replacement, output dimension specifications, subtitle burn-in, and watermark overlay.

How to Use the Video Merge Endpoint

To merge videos, you must provide at least one video URL as input. You can also specify optional parameters to customize the output. Here's a step-by-step guide on how to utilize the Video Merge endpoint effectively.

Make sure you have your API key ready, as authentication is required for making requests.

  • Input video URLs: Provide an array of video URLs to merge.
  • Optional audio URL: Replace the default audio with your own.
  • Output dimensions: Specify the desired resolution such as '1920x1080'.
  • Personalize your video: Add subtitles and watermarks as needed.
import requests

url = 'https://ffmpegapi.net/api/merge_videos'
data = {
    'video_urls': [
        'https://example.com/intro.mp4',
        'https://example.com/main.mp4'
    ],
    'dimensions': '1920x1080'
}

headers = {'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json'}
