Where it works

A coffee cutaway, from text

How to use AI B-Roll Generator
Describe the cutaway
Subject, action and setting, plus the look: “slow motion”, “close-up”, “shallow depth of field”.
Match your footage
16:9 for YouTube, 9:16 for Shorts. Name the light (warm morning, neon night) so it cuts in with your main shots.
Generate and drop it in
Download the MP4 and put it on the timeline over your voiceover.
What is a b-roll clip?
A b-roll clip is supporting footage cut in over the main shot, like hands typing, a coffee pour or a city at night. An AI b-roll generator makes those clips from a prompt, so you get the exact shot your edit is missing.

Matching b-roll to your video
B-roll works when it feels like part of the same shoot. Say the light and color of your main footage in the prompt, and keep the camera move gentle: a slow push-in or a slight drift. Five seconds is usually enough for a cutaway. Kling clips start silent, which suits footage that sits under your own voice; for clips with ambience, switch to Veo 3.1 or Seedance 2.0.
