auto-edit.ps1

<#
.SYNOPSIS
    Runs a new instance of auto-editor.
.DESCRIPTION
    Runs a new instance of auto-editor by using several folders.
    It also installs auto-editor if it is not present, however it still needs the user to choose the proper version of ffmpeg from a webpage.
    
    Run this file in a folder that contains the auto-editor folder or edit the default value for -Loc (Currently Line 46), or always specify -Loc.
    
    For more information see 'get-help .\auto-edit.ps1 -full'
