Topic $TipTopic

SRT captions are text files which are both easy to read and easy to edit. These text files can be opened in any text editor, such as Text Edit or BBEdit.

The format of the text inside the file is very specific:

  • Caption number. This must be on the top line and a unique, sequential number.
  • Timecode. This indicates the start and end of the caption, with the last set of numbers set off by a comma and representing milliseconds.
  • Caption text. This is one or two lines of text. Notice that this text file does not support significant text formatting.

As long as your text lines don’t run too long, you can easily correct spelling or punctuation errors.


While you can correct timing in this file, Final Cut makes timing adjustments easier within their respective programs.

    I find the easiest way to edit is to upload a quick version of the video to YouTube along with the SRT file. Then i use YouTube’s software to edit the text. Finally I download their edited fie and the thing is done.
