How do I add text, images and sound effects with B-Roll?
B-Roll lets you layer a heading, an image, or a sound effect on top of any scene without changing the scene itself. Use it for titles, callouts, product shots, logos, or sound effects.
Open Edit Video
- Click the scene you want to add to.
- In the left toolbar, click B-Roll.

The B-Roll panel has three sections: Add Text, Add Image and Add Sound Effects.
Add text

- Under Add Text, click Add a heading, Add a subheading or Add body text. The text appears on the scene preview.
- Click the text on the preview to type your own words.
- Use the toolbar above it to style it:
- Font (e.g. Raleway)
- Size: use – and +
- Colour: click A and pick a colour
- Drag the text to move it, use the corner handles to resize it and the round handle below it to rotate it.
Add an image

- Under Add Image, click Upload Image, drop a file or paste a file or URL (PNG or JPG, up to 1 MB). You can also click Select from Library.
- The image appears on the scene. Drag it to move it and use the handles to resize or rotate it.
- To swap it, click the image and click Replace.
Set when it appears

Every text and image has a Start and End time in its toolbar. By default, it shows for the first 3 seconds of the scene. Type new times to change when it appears and disappears, for example Start 00:00.0 and End 00:04.0.
Add a sound effect

Under Add Sound Effects, press play to preview a sound, then add the one you want. Click See All to browse the full library.
Check your result
- Use Shot, Scene and Full Video above the preview to play just the shot, the whole scene or your whole video.
- Click Back to return to the storyboard. Your B-Roll now shows in the video preview.
💡 Tips:
- Put headings near the top of the frame so they do not cover faces.
- Keep text on screen for at least 3 seconds so viewers can read it.
- For text across the whole video, use Captions instead.
