How to Add Subtitles to a Video Including Youtube

Last Updated: Oct. 19, 2020

Adding subtitles to a video is essential for viewers to grasp the key information you want to convey in a video.

In this blog, you will learn how to add subtitles to your video in 3 best ways, including adding subtitles to a Youtube video. It’s 100% work and super easy.


Add Subtitles to a Video Automatically with Srt File

Of all the means to add subtitles to a video, inserting an Srt file to your video is the easiest and quickest way to do so.

An Srt file (or SubRip Subtitle File) is a text-based raw file that contains the words of your subtitle and the exact timeframe when a subtitle is shown and disappeared.

Make an Srt File for Your Video Subtitles

To add the subtitle to your own video, you need to make an Srt file.

It’s very easy and you may use text editors like Notepad, Wordpad, TextEdit, etc. to edit it. Check the top 3 movie subtitles websites.

Step 1 Open the text editor.

Step 2 Edit the No. of subtitles + the subtitles’ timeline (e.g. “hours: minutes:second: milliseconds”) + the subtitle itself

Step 3 Save subtitles as “video name”.Srt format

Then, all you need to do is play your video with a media player like VLC to and right-click the video and add the Srt file to it.

Download Srt File Online and Add It to a Movie

If you just want to add the missing subtitles for a movie, you can simply google “movie name + language + subtitles” and download the Srt file. For example, search for “Inception, English, subtitles”.

  • Only when the name of the movie file and that of the Srt file are the same can the media player load it and play it.

However, there are two drawbacks to Srt files:

  • Secondly, not all the media players support Srt files.
