A couple of days ago we featured on this blog theRenamer, a great software the could rename downloaded movie and TV show video files by automatically inserting episode names, titles, etc to the file name. While the software did an excellent job on renaming video files, it did not rename any associated subtitle files. As you might know, most computer applications, built in media players on DVD, Blu-Ray players & modern TVs require subtitle file names to match those of video file names for subtitles streams to display properly. When file names are mismatched, you will be left with the painstaking task of renaming each file manually, which can take quite some time if you are dealing with something like a TV show with multiple seasons. SubDude is a useful little utility that can automate this rename process and save you a lot of time.


To clear any confusion, SubDude does not only work with video files renamed using theRenamer. You can use it to automatically rename even downloaded subtitles. Following table shows how SubDude will rename the subtitle file of a single TV episode:

  Before SubDude After SubDude
Video Filename The.Sopranos.s03e01.avi The.Sopranos.s03e01.avi
Subtitle Filename The-Sopranos3x1.srt The.Sopranos.s03e01.srt

How this software works is pretty simple. It matches the season and episode numbers in video and subtitle files using regular expressions (RegEx) and renames the matches accordingly. Below are some instructions on how to use the app, in case you didn’t figure it out already":

  1. Move all your subtitle files and video files inside a single directory (see notes below for additional details).
  2. Launch SubDude. In the ‘Rename’ tab, browse and point to the directory with files you created in Step 1.
  3. If you want to later undo the rename actions, check ‘Create and unDude file’ checkbox.
  4. Press Go.

Important Notes (Quoted from developer page):

  • SubDude assumes that every files in the folder are from the same show and checks season and episode numbers only.
  • Subdude uses regular expressions to detect season and episode numbers. Most common patterns (TVShow-s04e01, TVShow-4x1 etc) are handled, however Subdude will eventually fail to detect season and episode numbers on certain files (TVShow401 etc). This problem is being worked on.

    As I have already said in my previous comment theRenamer will do [b]rename[/b] your subtitles. Will not work if you drag them without the movie file (mkv,avi, etc). I didn't read the entire article, but if does nothing but renaming the subtitle it's useless
    PS: to prove that have a look in this screenshot: http://i52.tinypic.com/5vtykm.jpg

    You are correct theRenamer does rename subtitle files if you drag them into the app. Never tried that earlier. Thanks for the tip.
