Simple shell script for concatenating video files

vidcat

Simple shell script for concatenating video files of the same dimensions and encoding.

This simply copies the data and does not re-encode, so it's speedy (hours of video will concatenate in seconds).

Prereqs

• ffmpeg
  • Mac users can install with

    brew install ffmpeg
    

Install

Mac/Linux/Unix

1. Copy vidcat somewhere that you want it.
2. cd to that directory.
3. chmod 755 vidcat
4. When you want to run it, specify the path:

   ~/mydir/vidcat *.mp4 outfile.mp4
   

Alternately, you can add that directory to your PATH variable so that the shell can always find vidcat. E.g.

mkdir -p ~/.local/bin
cp vidcat ~/.local/bin
chmod 755 ~/.local/bin/vidcat

and in your ~/.bashrc file:

export PATH=$PATH:~/.local/bin

then relaunch your shell. You should be able to then:

vidcat *.mp4 outfile.mp4

from any directory.

Windows

1. Install bash somehow
2. Install vidcat kinda like for Mac
3. ...
4. Profit!

Usage

vidcat vidfile [ vidfile ... ] outfile

vidcat will steadfastly refuse to overwrite any existing file. Manually remove your outfile ahead of time if you need to overwrite it.

Examples

vidcat zoom*mp4 outfile.mp4

vidcat zoom_1.mp4 zoom_3.mp4 outfile.mp4

vidcat *.mp4 outfile.mp4
