Does it change my original video?

No. The footage is delivered untouched and the captions are the only thing added.

What styles does it offer?

A catalogue of 35 identities. By default it uses a quiet verbatim caption along the lower part of the frame and saves words placed behind the speaker for the peak moment.

Do I need external services?

The workflow, including transcription and subject matting, runs locally. It needs Node, FFmpeg and a few dependencies installed in the project.

Cinematic captions for video

/embedded-captions

/embedded-captions is a Claude Code skill in the Video & Motion section. It is maintained by heygen-com and published under the Apache-2.0 license. Adds captions to a talking-head video without touching the footage, from quiet verbatim text to words placed behind the speaker.

Author's description

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet `anchor` rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.

Use it when

You have a single-speaker video and want captions without editing the footage
You want quiet, verbatim, readable subtitles
You want a bold visual effect, with words behind the speaker, for a key moment

Not for

Multi-shot footage: split it into single shots before applying it
Editing or trimming the video: it only adds captions and leaves the picture intact

What you get

A final MP4 with the captions composited over your original footage, which is delivered unmodified, after frame previews and timing and overlap checks.
