How to Add B-Roll in CapCut

Quick answer
In CapCut, B-roll is added as an overlay. On mobile, tap Overlay → Add overlay and pick your clip; on desktop, drag the clip onto a track above your main video. Resize it to fill the frame, then move and trim it on the timeline so it covers the right line.

Before you start
Gather your B-roll first: short clips you own or have permission to use, ideally in the same aspect ratio as your project. (See the aspect ratio guide.)
On mobile
- Open your project with the main (talking-head) clip on the timeline.
- Move the playhead to where the cutaway should start.
- Tap Overlay, then Add overlay, and choose your B-roll clip.
- Pinch to resize it until it fills the frame (for a full cutaway) or leave it smaller for picture-in-picture.
- Drag the overlay along the timeline and drag its edges to set when it starts and ends.
- Lower or mute the overlay's volume so your voice stays clear.
On desktop
- Import your main video and B-roll clips.
- Put the main video on the main track.
- Drag a B-roll clip onto a track above it.
- Select it and resize it in the preview to fill the frame.
- Move and trim it to the line it illustrates.
- Adjust its volume.
Button names and positions can change between versions and regions; if you can't find a control, follow the labels in your build.
Timing tips
- Start the cutaway on the word it illustrates.
- Use cutaways to cover jump cuts. (More here)
- Keep most cutaways around 3–5 seconds. (More here)
Common mistakes
- Leaving overlays smaller than the frame by accident, showing the base clip's edges.
- Forgetting the overlay's own audio.
- Mixing aspect ratios.
