In today's digital world, video content is king. Whether you are developing a content pipeline, creating SaaS applications, or automating video processing tasks, having a reliable video processing API is crucial. FFMPEGAPI.net offers a hosted REST API that takes care of all the heavy lifting involved in video and audio processing, making it the best choice for developers looking to streamline their workflows. In this article, we will dive into the Video Merge endpoint, a powerful feature that allows you to concatenate videos seamlessly.

What is the Video Merge Endpoint?

FFMPEGAPI.net's Video Merge endpoint enables developers to merge multiple videos into a single MP4 file effortlessly. Unlike traditional methods that require managing FFmpeg installations and server configurations, FFMPEGAPI.net abstracts all that complexity away. You simply provide the URLs of the videos you want to merge, and the API handles the rest.

  • Concatenates videos while normalizing their formats.
  • Supports optional audio replacement.
  • Allows for subtitle burn-in and watermark overlays.
  • Can process videos asynchronously, providing a job_id for tracking.

Using the Video Merge API

To use the Video Merge endpoint, you will make a POST request to /api/merge_videos. The request should include a JSON payload containing the video URLs you wish to merge, along with any optional parameters like audio URL, output dimensions, subtitle URL, and watermark URL.

  • The 'video_urls' parameter is mandatory.
  • All other parameters are optional and can enhance the processed video.
  • You can specify dimensions in the format 'WIDTHxHEIGHT'.
import requests

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

response = requests.post(url, json=data)
print(response.json())
curl -X POST https://ffmpegapi.net/api/merge_videos \
-H 'Content-Type: application/json' \
-d '{"video_urls": ["https://example.com/intro.mp4", "https://example.com/main.mp4"], "dimensions": "1920x1080"}'
