Subtitles are burned in with word-level timing and an animated highlight on the active word.
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 is handled for you — a bold readable font with an animated highlight — and 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.
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.
