  1. ## ConvertVideo.ps1
  2.  
  3. ## Requires FFMPEG https://www.ffmpeg.org/download.html
  4.  
  5. ## Batch converts a directory of files to the a given format
  6. ## eg
  7. ## Given a directory with files:
  8. ## vid1.mkv, vid2.mkv, vid3.mkv
  9. ## Running the command ConvertVideo.mp4 -filepath %PATHTOFILES% -convertto MP4
  10. ## the results would be:
  11. ## vid1.mp4, vid2.mp4, vid3.mp4
  12.  
  13. ## Usage:
  14. ## ConvertVideo.ps1 -filepath %PATHTOFILES% -convertto %EXT% [-ffmpeglocation %PATHTOFFMPEG%]
  15. ## -filepath is the path to the files to be converted, spaces must be quoted, trailing slash must be added
  16. ## -convertto is the new extension.  Extension must be supported by ffmpeg https://www.ffmpeg.org/documentation.html
  17. ## -ffmpeglocation (optional) is the filepath to ffmpeg.exe.  Default is "c:\program files\ffmpeg\ffmpeg.exe"
  18.  
  19. ## eg:
  20. ## ConvertVideo.ps1 -filepath c:\scripts\videos\ -convertto MP4
  21. ## ConvertVideo.ps1 -filepath "c:\batch files\videos\" -convertto FLV
  22. ## ConvertVideo.ps1 -filepath "c:\batch files\videos\" -convertto FLV -ffmpeglocation "c:\program files\audio files\ffmpeg\ffmpeg.exe"
