AI B-Roll Generator

B-roll is the footage that carries a story: the cutaways under a voiceover, the establishing shot before a scene, the texture that keeps a talking head from feeling static. Most AI B-roll tools solve the placement problem. They read your finished video, guess the moments that need a cutaway, and drop in a stock clip or an auto generated one on a closed timeline. That is convenient, but you take whatever the match returns, and the look is bound to that one editor.

Wireflow treats B-roll as a workflow you own on a node canvas. A Text Input holds the shot description, Nano Banana Lite renders a controllable establishing frame, and a Seedance 2.0 node animates that exact frame into motion. Because it runs on hosted compute in the browser with nothing to install, the same canvas that makes a cutaway also drives every other AI video generator job your team runs, and a finished clip is an asset in the graph rather than a dead export.

The workflow behind this page's button is deliberately small: one Text Input and two model nodes.

• The Brief holds the shot. One line describes the cutaway, for example a slow push in on a steaming espresso cup on a rain soaked cafe table at golden hour.
• Nano Banana Lite renders the frame. The brief becomes a controllable establishing frame, the still you approve before paying for motion.
• Seedance 2.0 animates the frame. The node reads that frame plus the brief and returns a short cinematic clip, so the motion starts from the composition you chose.

That frame first order is the detail worth copying: you judge the still before spending on the clip, which is the asset first habit behind a controlled shot. It also makes testing cheap. When you want to try three different B-roll openings for an ad, you rerun the brief three ways and generate ad variants from the same canvas, rather than re editing in a closed tool. A clip that works does not sit in an export; it wires forward into the next shot in an AI video workflow.

If your job is to take a finished talking head video and have software watch the transcript and drop cutaways onto a timeline for you, a dedicated auto insert B-roll tool is built around exactly that, and this page will not pretend otherwise. Wireflow does not read your video and place clips, and it is not a stock footage library you search. It generates the shot you describe.

Wireflow is the generation layer, not the edit bay: it will not cut your sequence, sync to your voiceover, or decide where a cutaway belongs. What it offers instead is ownership of the pipeline, 70+ hosted models to swap between, a controllable frame before motion, and per generation pricing. If your B-roll is a shot you want to author and reuse rather than a clip auto dropped into one editor, build it here, and pair it with image to video AI when you already have the frame you want to move.
