How to make all video files in a directory have a uniform naming format

The title for this page is a bit confusing, but the idea is simple. Rename all video files to standard format or style. If you download TV episodes from different sources they often use different naming styles and formats. This can be very annoying. For example:

  • The.Good.Guy.S01E01.HDTV.XviD-LOL.[VTV].avi
  • The Good Guy S01-E02 - the math test - HDTV XviD-2HD.avi
  • the good guy - 1x03 - happy days.avi
  • The_Good_Guy_-_S01_E04_-_HDTV_XviD.avi

The following script renames the files to follow a standard format.

FeaturesEdit

  • Removes all special characters
  • Replaces all spaces and underscores with periods
  • Removes common tags, ex HDTV, XviD, LOL, [VTV], DIVX, ...
  • Makes all characters lowercase
  • Renames only video files
Flaws
  • Cannot fix problems like the following
    • if the real title is 'The Good Guy' and some files use 'The Goodguy'
    • This can be manually fixed by adding a line to 'sub renamer' like the following. (use \. as spaces)
      • $oldname =~ s/the\.goodguy/the.good.guy/;

Standard format used Edit

  • [title].[season][episode].[episode name].[extension]
  • Example: the.good.guy.0103.happy.days.avi

ExamplesEdit

Original files
  • The.Good.Guy.S01E01.HDTV.XviD-LOL.[VTV].avi
  • The Good Guy S01-E02 - the math test - HDTV XviD-2HD.avi
  • the good guy - 1x03 - happy days.avi
  • The_Good_Guy_-_S01_E04_-_HDTV_XviD.avi
Renamed files
  • the.good.guy.0101.avi
  • the.good.guy.0102.the.math.test.avi
  • the.good.guy.0103.happy.days.avi
  • the.good.guy.0104.avi
