Built for Short Video — beyond CapCut
Not just better than editing apps — even rolling your own with an AI agent (like Claude Code) can't give you a repeatable cut that learns your style.

Frequently asked questions
- What formats and lengths are supported?
- MP4, MOV, MKV and other common formats up to 10 GB — or just paste a YouTube or Google Drive link. Long videos are auto-analyzed into multiple short clips.
- Can I upload my own font and download the caption file?
- Yes — upload your own font for the captions, and export them as an SRT file to reuse or edit elsewhere.
- What content works best?
- Variety shows, podcasts, interviews, livestreams, gaming, tutorials, vlogs, news, lectures, and stand-up all work well.
- Can't I just cut video with an AI agent like Claude Code?
- Technically yes — an engineer can wire ffmpeg, Whisper and a few APIs into a transcribe → select → burn-captions pipeline. But that needs code, API keys and a lot of debugging, and it's a one-off script: no UI, no preview, no memory, and you start over for every video. OpusCut productizes all of it: a non-coder operates it in a UI, and it learns and reproduces YOUR editing style — getting better the more you use it.
- How is OpusCut different from generic AI editors?
- Most tools only do 'AI finds the highlights' — which is becoming table stakes. OpusCut's edge is three things: ① Clone Your Cut reproduces your personal style (captions, pacing, selection, motion cards all learned from your own shorts); ② depth in Traditional Chinese / Taiwanese; ③ output that doesn't look AI-edited — natural framing, speech-aligned captions and motion — so it keeps its reach when you publish.
- Do I have to pay?
- New accounts get 50 free credits to try. Usage is billed by video length, pay as you go, no credit card required.
