How to Add Speech Bubbles in Windows Movie Maker in Vista
In Windows Movie Maker for Vista, an application that allows you to create and edit video projects, you can add captions that can be used as speech bubbles. This effect can be used for comedic purposes, or to act as a "closed captioning" feature of sorts for deaf or hard-of-hearing viewers. It can also be used to help translate dialogue into different languages to reach a wider audience.
Open the Windows Movie Maker application on your Vista PC.
Click "File" and then "Open Project." Select your video project, and then click the "Open" button.
Click the "Caption" option in the toolbar at the top of the screen.
Drag the text box to the position you want on the screen. If you're using the caption as a speech bubble of sorts, you could place the box above someone's head in the video.
Type your speech text inside the caption box. When you play the video, your speech box will now appear on screen in the position you selected. You've successfully added speech bubbles or captions in Windows Movie Maker for Vista.
