If you wish to edit the subtitle content, download the subtitle file and use a text editor.

or edit directly using apps like Notepad.

How to Add Subtitles to Videos from a Subtitle File in Adobe Premiere

Next, we will explain how to add subtitles using "Adobe Premiere" and "DaVinci Resolve," which are widely used by video editors.

First, let's look at "Adobe Premiere."

※This guide uses Adobe Premiere 23.6.0.

1. Open the Project

First, open the project to which you want to add subtitles.

In this example, only the video footage is loaded, with no subtitles or captions whatsoever.

2. Import the Subtitle File (SRT File) as Media

Import the SRT file of the transcribed subtitle text as media into the "Project" panel.

You can drag and drop the SRT file, or

import it from the menu: "File" → "Import."

※This is the same process as importing other media like videos or audio.

The SRT file has now been imported, as shown.

Drag and drop the SRT file onto the timeline.

A dialog box titled "New Caption Track" will appear. Click "OK."

Once the subtitle adjustments are complete, encode the video in its final format, such as MP4.
