How to add a dialogue bubble box to a video screen?

Well, you need a tool that can add dialogue bubbles to video images.

Open the software and add the video file to which you want to add the dialog box to the screen of the software.

Then switch to the subtitle library, find the dialogue bubble box we want, add it to the text track below the software, and then adjust the display time and display duration of the dialogue bubble box on the track.

Then double-click the dialogue bubble box in the track to enter the dialogue bubble box editing page to edit the text content, display position, font size and color of the text in the dialog box.

Then we can output the video file after editing the dialogue bubble box. Click the "Export" button at the bottom right of the software to enter the video output setting page. After the output setting is completed, click the "Start" button to start outputting video files.
