When it comes to social media, viewer engagement is critical. Adding subtitles to your videos is as important as adding music. You must use subtitles to make your audience understand and contextualize your video content.

All of us understand the importance of having subtitles in a video but how exactly do we add subtitles to video, is the question that intrigues all of us.

How to Add Subtitles to Video?

There are a few video making apps that help you add text on video. But Rocketium, an online video editing tool, lets you do it for free!

STEP 1: Create an account with Rocketium, a free online video editor

Head over to Rocketium and create an account.

STEP 2: Head over to the Editor

You will notice that there are 2 timestamps for every caption box. The left box represents the start time and the other represents the end time. You will also notice that some default values are already present. These timestamps are calculated based on a default reading speed of 150 words per minute.

To sync the captions with the video, you need to click on the icon above the timestamp boxes. First, play the video and everytime the caption starts playing, click on icon above the ‘start time’ box. When the caption is over playing in the video, click on the icon above the ‘end time’ box.

Check out this tutorial:

You can also manually enter the timestamps. Just play the video, note the start and end time of a particular caption, and enter the value manually in the space provided.

STEP 4: Style your video

There are multiple ways to show subtitles, and you can find relevant themes in the ‘Theme’ tab on your left.

  1. I used to think that only professional video editors such as openshot can add subtitles to the video. Later, I found that many amateur tools can do this, such as hd video converter factory pro, which is more than just a video converter, but also supports adding subtitles. Amazing, right?
