ffmpeg - Subtitles - Preparing an SRT Subtitle file

An SRT file (SubRip Subtitle file) is a text file that contains subtitle information for videos, including the text of the dialogue and the timing for when each subtitle should appear and disappear on the screen.

Every SRT file consists of these four components:

• The counter/index for the subtitle.
• The start and end time of the subtitle in “hours:minutes:milliseconds” format.
• The subtitle text.
• A blank line to indicate the end of the subtitle.

Use any text editor to add texts to the subtitle file.
