One recording, every vertical format
Filming 16:9 and posting 9:16 throws away 65% of the width. A centred crop leaves whoever is speaking out of frame in half the takes — so here the crop follows the face.
The same project exports 9:16 for Reels and TikTok, 4:5 for the Instagram feed, 1:1 and 16:9 for YouTube. Captions, name bar and highlight are positioned per format.
Cutting pauses is free and needs no account.
How it works
This is what happens the moment you open a recording, before you decide anything.
What you get
Every one of these is a switch. Turn on what this video needs and leave the rest alone.
Reframing that follows the face
16:9, 9:16, 4:5 and 1:1 from one recording. The crop tracks whoever is speaking, one framing per take.
Captions from the speech
Already in sync, with ready-made styles and a screen to fix proper nouns before export.
Pauses cut automatically
Silence, hesitation and dead air are removed in the browser, before anything is uploaded. Free, no account.
Name bar, highlight and end card
Lower third, one sentence in focus and a closing card with your logo — placed on the preview itself.
Soundtrack that ducks under you
Generated to the length of your edit, dropping on its own while you speak.
Colour measured on your footage
White balance, levels and contrast from your own material, plus looks. Two cameras are matched to each other first.
Questions
The ones people ask before trying it.
What does NinjaClip do?
It removes silence and hesitation, reads the transcript to flag false starts and repeated lines, generates captions in sync, reframes 16:9 footage to 9:16, 4:5 or 1:1 following the speaker, levels the voice, corrects colour, adds a soundtrack that ducks under speech, and exports the finished video or a timeline for Premiere, Final Cut and DaVinci.
Can NinjaClip automatically add captions?
Yes. Captions are generated from the speech, already timed, with several styles and a correction screen for names and jargon. Only the audio is sent for transcription, and it is not stored.
Does NinjaClip work in the browser?
Yes. Editing runs entirely in the browser and your video file is read straight from your computer — it is never uploaded. Producing the final file works in Chrome, Edge, Safari and Firefox; Firefox writes WebM instead of MP4.
Is NinjaClip free?
Cutting pauses is free and needs no account. Captions, take selection, soundtrack and export need a free account, because they use a server — five videos a month while the beta lasts.
What files can I open?
Whatever your browser opens: MP4 and MOV in H.264 or HEVC, and WebM. You can drop several files at once and they become one video, in the order you picked them.
