Add B-Roll to Video Without Hunting for Clips
A talking head holds attention for a few seconds, then the eye starts to wander. VoxCut adds B-roll and stock footage over your dialogue automatically, so the picture keeps changing while you keep talking. It runs in your browser alongside Auto Captions and 9:16 reframing, with a free plan to start.
Stock footage that lands where the words call for it
The hardest part of cutting B-roll by hand is finding the right clip and dropping it on the right second. VoxCut's auto B-roll pulls stock footage and layers it over your talking-head video for you, so a long monologue stops being one static shot and starts moving with what you're saying.
It works on the kind of footage most creators actually have: a single camera, one person talking. Instead of leaving that shot untouched for a full minute, the auto B-roll breaks it up with cutaways, which is usually the difference between a clip people finish and one they swipe past.
B-roll, captions and reframing in one pass
Auto B-roll isn't a separate detour. In the same browser tab, VoxCut reframes horizontal footage to vertical 9:16 and generates word-level Auto Captions burned straight into the file, so the stock footage, the crop and the subtitles all land on the same export.
That pairing matters for short-form. Captions carry the muted viewer, the 9:16 crop fills the phone screen, and the B-roll keeps the visual moving underneath. You set it up once and get a clip that's already shaped for TikTok, Reels and Shorts rather than a raw recording you still have to dress up.
Built into the short-form workflow, not bolted on
Most VoxCut videos start as something longer. Clip Factory splits one long recording into a batch of short vertical clips in a single pass, and Best Moments uses AI to surface the strongest segments to cut. Auto B-roll then keeps those clips from feeling like a flat slice of someone talking.
If you publish under a brand, the Brand Kit locks your fonts, colors and watermark across every export, so adding B-roll never throws off your look. You can also generate titles, hooks and descriptions with the AI tools, or add a TTS voiceover in Voice Studio before the clip goes out.
From a talking-head recording to a posted clip
The flow is simple: upload your talking-head video, let VoxCut reframe it to 9:16, add Auto Captions, and let auto B-roll layer stock footage over the talking sections. You preview, adjust, and export a finished vertical clip. The interface is available in 10 languages and nothing is installed.
When the clip is ready, you can post or schedule it straight to TikTok and YouTube from the same place. VoxCut has a free plan to try auto B-roll in the browser, and paid plans start at $5.67/month if you need higher limits.
