Stellar Converter for Audio Video has an added feature to add subtitles to videos. You can add English language subtitles to video with no audio or to those in different languages. The feature helps to better comprehend the video, especially the tutorials, how-to, or training videos.

The software supports .srt files for adding video subtitles.

What is an SRT file?

SRT or a SubRip Subtitle file is a text file that has information about video subtitles. It includes the start and end timecodes (as hours:minutes:seconds,milliseconds) of the text, so that the audio matches with the video.

Example subtitle text in a .srt file:

  1. 00:00:03,254 --> 00:00:08,467 Welcome to our show Discover Science.
