Customizing your subtitles can make them more legible and enhance the look and feel of your video. To do this, double-click the title in your Timeline and open the Text tab in the upper left corner of the application. Here, you can enter the text, choose its font, text size, and how it appears and aligns on the video. Next, open the Clip tab next to the Text tab to adjust how long your captions appear on the screen. This tab will also allow you to change the text and background color for your captions, and you can make edits to specific words or parts of the subtitles, as well. For example, if you want to change the color of the subtitles to visually differentiate between two people speaking in your video, you can do that here.
