B-roll is supporting footage laid over the main audio track, used to show what the narration is describing, hide an edit, or give the eye something new without changing the voice.
The name comes from editing with physical film, where the A-roll was the main take and the B-roll was everything else on a second reel. The job has not changed: cover the cut, illustrate the point, keep the picture moving while the voice keeps going.
A gameplay layer under a brainrot video is deliberately unrelated to the script. B-roll is deliberately related. Both keep the frame moving, but only b-roll adds information, which is why explainer and news-style faceless channels use it and story channels usually do not.
Stock libraries with a clear commercial licence are the safe route, and so is AI-generated imagery you prompt yourself. Clips lifted from other creators are the route that ends a monetization application, because reused content is what YouTube reviews for. See the YouTube Partner Program entry.
MakeViral generates the imagery for its meme and photo-reveal formats from the script itself, so every panel is made for that video rather than pulled from a library. See the AI voiceover video generator.
The narrator-over-gameplay format: a written script becomes a voiced, captioned vertical video with a background clip, in one pass.
