Overview

This node merges multiple video files into a single video file using FFmpeg. It is useful in scenarios where you need to combine several video clips into one continuous video, such as creating a highlight reel, compiling footage from different sources, or preparing a video for presentation. The node supports specifying a minimum number of files required for merging, customizing the output file name, and defining FFmpeg command arguments for the merge process.

Use Case Examples

  1. Merging multiple recorded video segments into one file for easier sharing.
  2. Combining clips from different cameras into a single video for editing.
  3. Creating a single video file from multiple short videos for social media posting.
