In the fast-paced world of content creation, having a reliable and efficient way to process media is essential. FFMPEGAPI.net offers a powerful hosted REST API specifically designed for video and audio processing, allowing developers to streamline their workflows without the need for complex server setups or FFmpeg infrastructure management. One of the standout features is the Video Merge endpoint, which allows you to concatenate multiple videos into a single, polished MP4 file.

What is the Video Merge Endpoint?

The Video Merge endpoint at FFMPEGAPI.net is a POST API that enables users to combine multiple video files into one. This feature is invaluable for developers looking to create seamless content pipelines or automate video editing processes.

This endpoint not only merges videos but also provides options for audio replacement, output dimensions, subtitle burn-in, and watermark overlays, making it versatile for various use cases.

  • Concatenate one or more videos into a single MP4.
  • Supports optional audio replacement.
  • Allows specification of output dimensions.
  • Enables burning of subtitles from ASS/SSA files.
  • Can add watermarks to the final video.

How to Use the Video Merge API

To utilize the Video Merge API, you must make a POST request to the `/api/merge_videos` endpoint. You must provide a list of video URLs to merge, with additional options provided for customization.

Here is a breakdown of the required and optional parameters for the API call:

  • Required: `video_urls` - Array of video URLs (at least one URL is mandatory).
  • Optional: `audio_url` - URL of the audio to replace the original.
  • Optional: `dimensions` - The desired output dimensions (e.g., '1920x1080').
  • Optional: `subtitle_url` - URL of the subtitle file for burn-in.
  • Optional: `watermark_url` - URL of the watermark image.
  • Optional: `async` - If true, the request will return a job ID for background processing.
