AI b-roll generator · landscape YouTube & explainer video

AI b-roll that matches what you actually said.

Most AI b-roll tools search a stock library for clips that loosely match your keywords. Ahacut generates the visual for each line instead: the number you quoted, the comparison you made, the step you described. One continuous track, already on your timecodes.

The script of our own homepage, rendered by Ahacut start to finish. Every scene lands on the line it belongs to.
An animated chart, generated from one spoken line.
A side-by-side comparison scene.

What you put in

Any one of these
  • →A voiceover or your finished video (audio is transcribed for you)
  • →Or an .srt / .vtt subtitle file exported from your edit
  • →Or a pasted script

What you get back

Rendered in the cloud, nothing to install
  • ✓One full-length b-roll track, the length of your edit
  • ✓Or a transparent overlay track (ProRes 4444 with alpha) to stay on camera
  • ✓Landscape 16:9 by default (vertical 9:16 too), ready for Premiere, Resolve, Final Cut or CapCut
How it works

Three steps, no keyframes

1

Upload audio, subtitles or a script

Your subtitle timings become the cut list. If you upload audio, it's transcribed first.

2

Each line becomes a scene

Kinetic type, numbers, charts, comparisons, diagrams and generated backdrops, composed per spoken line.

3

Drop the track on your timeline

It's cut to your timecodes, so it lines up with the edit you already made. Trim wherever you want your face back.

Who it's for

Ahacut is built for talking-head and voiceover content where the point is information: YouTube explainers, finance and tech channels, course videos, product walkthroughs, and agencies that edit this kind of video for clients. If your b-roll needs to show what you said rather than set a mood, generated motion graphics fit better than stock.

It's built for landscape, long-form video first. Most AI b-roll and caption tools started from vertical shorts of a minute or two; Ahacut defaults to a 16:9 track that runs the full length of a YouTube video, and switches to a vertical layout when you pick 9:16.

If you need cinematic footage of real places and people, a stock library or a generative video model is the better tool. Plenty of editors use both: Ahacut for the explanatory moments, stock for atmosphere.

What the scenes look like

Each line gets the treatment that suits it: animated charts and big numbers for data, side-by-side cards for comparisons, step diagrams for processes, kinetic typography for key phrases, and generated background images where a scene needs a picture. On-screen text is written in the language you speak, including Chinese, Japanese, Korean, Hindi, Arabic and more.

For agencies and editors with clients

Paid plans include brand kits: save each client's colors, fonts and logos once, then pick the kit per render so every video stays on brand. The output is yours to use in client work and monetized videos.

Frequently asked questions

What is the best AI b-roll generator for talking-head videos?
It depends on the b-roll you want. Tools like Jupitrr, Submagic and OpusClip match stock footage to your transcript, which suits lifestyle and atmosphere shots. Ahacut generates motion graphics for each line (numbers, charts, comparisons, kinetic text), which suits explainers, finance, tech and educational content where the visual has to show what you said.
Does it use stock footage?
No. Every scene is generated for your script. Nothing is pulled from a stock library, so there are no licensing questions about the clips and no reused shots.
Can I keep my face on screen instead of cutting away?
Yes. Choose overlay mode and you get a transparent ProRes 4444 track that sits on the layer above your footage. You can mark the area around your face to keep clear, and graphics are placed outside it.
Does it work for long horizontal YouTube videos, not just vertical shorts?
Yes, that is the main use. Landscape 16:9 is the default, and the track covers the full length of your edit. Vertical 9:16 is there for Shorts and Reels, with its own layout rules.
Is there a free trial?
Yes. New accounts get 3,000 trial credits with no credit card. Trial renders are capped in length; output has no watermark.
