Subtitles are burned in with word-level timing and an animated highlight on the active word.
In the editor
Two moments from the real review screen, up close.
Fix a word — the caption updates on the frame
Speech recognition heard “Cat” instead of “Cut”? Correct it in the Text tab and the preview shows the fixed word right away.
Change the style and watch it on your clip
Click through the presets — Pulse, Marker, Story, Boom! — and the captions on your video redraw instantly, before anything is rendered.
Caption presets: one tap, a finished look
Start from a ready-made style instead of a blank panel. Every preset sets the font, size, letter case, how the words appear and how the active word is marked — and you see it on your own frame before anything is rendered. Pick one, then change anything you like.
Pulse
Bold uppercase, three words at a time. The spoken word is white, the rest stay muted — the eye follows the voice.
Studio
Clean white text set slightly higher in the frame, up to four words, with a soft shading behind the letters for light backgrounds.
Rhythm
One calm line of up to five words; each word fades in exactly when it is spoken.
Boom!
Alternates a small lead-in row with a large payoff row, so the important words land bigger.
Clean
Plain, compact white captions in natural case — for interviews, tutorials and anything that should not shout.
Promo
White uppercase lines with the active word in gold — the look you see on our home page.
Dynamic
Heavy white headline type mixed with a handwritten accent, built up row by row like a creator edit.
Impact
One big gold word at a time with a short pop — for fast, punchy speech.
Marker
The spoken word sits on a rounded violet plate, like a highlighter running along the sentence.
Story
White text on a translucent dark backdrop — the familiar social-app caption, readable on any shot.
Statement
Two large rows with the emphasis passing to the second one — for quotes and key lines.
Label
Short uppercase phrases on a solid light plate, like a printed sticker on the video.
After choosing a preset you can still change the font, size, colours, highlight, number of rows, letter case and caption position — and save the result as your own style for the next video. With several clips, each can have its own style, or one button applies it to all.

Whisper-grade accuracy
Transcription runs on a Whisper large model that recognizes speech in about 100 languages, with automatic language detection.
Grammar cleanup included
A language model corrects the raw transcript — punctuation, casing, misheard words — before it ever reaches the screen.
Animated, not static
Words appear in sync with speech and the active word is highlighted — the caption style that keeps viewers watching.
Editable before render
Review the transcript, fix names and jargon, then render. What you approve is exactly what gets burned in.
Why burned-in subtitles matter
The majority of short-form video is watched with the sound off, at least for the first seconds — no captions usually means an instant scroll-away. Platform auto-captions exist, but they are often inaccurate, unstyled and can't be edited. Burned-in subtitles look identical everywhere: Shorts, Reels, TikTok, or embedded on your site.
Wow Cut Video generates subtitles at word-level timing, so each word pops exactly when it's spoken. Styling starts from a preset — Pulse, Studio, Promo, Marker, Story and more — previewed on your own frame, then fine-tuned if you want. Everything renders in a single pass, so the output is one clean MP4.
Subtitle a whole video or just the clips
You can subtitle a full video as-is, or combine captioning with AI clipping: the same upload can produce subtitled highlight clips for social media. Source speech is recognized in about 100 languages, and if you need the captions in a different language than the audio, built-in translation covers 12 output languages.
Frequently asked questions
How accurate are the subtitles?
Transcription uses a Whisper large-v3 class model — among the most accurate speech recognition available — followed by an LLM grammar-correction pass. You can also edit the transcript before rendering.
Which languages are supported?
Speech is recognized in about 100 languages automatically. Subtitles can be rendered in the original language or translated into 12 languages.
Can I edit the subtitles before they're burned in?
Yes — the transcript is shown for review and every word is editable before the final render.
Are the subtitles a separate file or burned in?
Burned in: you get a final MP4 with animated captions that look the same on every platform. No SRT juggling.
Can I change how the subtitles look?
Yes. Pick one of 12 caption presets, then adjust font, size, colours, word highlight, rows, letter case and position on the preview. You can save the result as your own style.
How long does it take?
Transcription is near-instant on the fast path and rendering is a single video pass — most videos are done in 2–4 minutes.
