Use supporting shots to show the point
About this video
Alex is a fictional illustrated presenter with audio-reactive animation. Narration is AI-generated. Editor visuals are screenshot walkthroughs; inspect the interactive demonstrations below as you follow along.
Place B-roll where it adds evidence and preserve the main audio.
B-roll is supporting footage shown while the main story continues. In a lamp review, a close-up of the switch belongs near the sentence about the switch. A random city skyline may look polished but adds little to that claim.
Put a supporting shot on a visual track above the speaking clip when you want the narration to continue underneath. Check its audio: a noisy camera recording can compete with the speaker. Mute that supporting clip if you only need its picture. Listen again after the change so you do not accidentally mute the main voice.
B-roll can hide a visible jump between two parts of a talking-head recording. It should still have a reason to be there. Start it around the idea being explained and end it when the viewer has had time to see the detail. Repeatedly cutting away before the viewer understands a shot makes the video feel busy rather than helpful.

From a file to your first timeline clip
Real editor screenshots · September 2026 · Select a step, then tap the image to zoom.
Start in the Media library
Choose Upload / drop media and select the three lamp images from the practice pack. A source in the library is available to use; it is not yet part of the finished video.
Find the upload area, then the three source cards.
Place a source on the timeline
Double-click lamp-wide.png in the library. In this captured example, it becomes a five-second clip on V1. Select the clip before changing its properties.
Look for the outlined clip on V1. The ruler above it is time.
Read the whole workspace
The library is on the left, the picture in the middle, and the selected clip’s Motion controls on the right. The timeline below decides what appears and when.
Select your own clip and check that the inspector follows your selection.
Step 1 of 3
Follow along in Vidmoat
- Identify one sentence that would benefit from a visual example.
- Add a matching close-up to a track above the main recording.
- Align it with the relevant sentence, using timeline time.
- Mute the close-up audio if it is unnecessary. Keep the narration audible.
- Play the sentence before, during and after the insert. Adjust its duration.
A prompt you can adapt
Show my uploaded switch close-up while I explain the switch. Keep the main recording’s voice continuous underneath and mute the close-up’s camera audio. Use the real product shot, not generated replacement footage.
Your turn
Cover one visible talking-head jump with a relevant detail shot. Then remove the insert and compare what the viewer understands in each version.
What a successful attempt looks like
The insert supports a specific phrase, stays visible long enough to inspect, and does not interrupt the voice.
A common trap
Putting two full-volume recordings on top of one another can create an echo or a distracting second conversation.
