Animated captions

Brand fonts
Use a built-in font or upload your own brand font, keeping the same look from clipping through advanced editing — instantly recognizable as yours.

How it works
Drop a YouTube / Google Drive link, or upload a video file up to 10 GB.
OpusCut analyzes the whole video, picks post-worthy segments, reframes vertical, and adds captions.
Swap caption style, font, and color, or do advanced edits, then download HD / 4K to post.

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.
