When we are watching a TV show or program produced in foreign languages, subtitles are crucial for us to understand what is going on. But in a lot of video resources, multilingual subtitles are usually not included, which requires us to manually add an outside SRT subtitle file in order to enjoy the video better. Adding an SRT subtitle file to an AVI video is not hard as long as you have the right application. So today I’m going to introduce some tools for you to add SRT subtitles, and explain how you can do that with these tools.

Part 1: About SRT Subtitle

SRT files are also known as SubRip Subtitle files. They are simple plain text files that contain not only subtitle text information, but also the start and end timecodes of each subtitle line to ensure your subtitles match your video and audio when it’s being played. Since SRT files are just plain text files, it’s easy to create an SRT file with any text editor tool like Notepad++, TextEditor or just the native text editor tool on your computer. To create an SRT subtitle file, you just have to follow the SRT file format to edit your file, and then save it as a file with the “.srt” file extension.

SRT files can be added to an AVI movie or any other movie files by using some video editor applications. They can also be added live in the playback process if the player has the outside subtitle support. Neither of the two subtitle adding approaches are complicated to do. As long as your timecode in the SRT file matches the actual video, the subtitle you add could bring you an absolute perfect watching experience.

Part 2: About AVI File

If you want to add an SRT subtitle to an AVI movie, you also have to know something about the AVI file format. As one of the most popular and compatible video formats, AVI was introduced by Microsoft in 1992 and is supported by most of the video playing devices and platforms up till this day.

The full name of AVI is Audio Video Interleaved, meaning the container format can have both audio and video data saved in one file and supports synchronous audio-with-video playback. With a synchronized video and audio playback, an AVI file could be made even more perfect and enjoyable with a single well-timed SRT subtitle file added.
