Which players actually support these embedded chapters?

Most modern video players and platforms that support the chapter metadata standard will recognize and display them — support varies by specific platform.

Is this different from just writing timestamps in a video description?

Yes — timestamps in a description are just text; this embeds real, navigable chapter markers into the file's own metadata, which is supported natively by compatible players.

How many chapters can I add?

As many as your video naturally breaks into — there's no meaningful limit for typical use.

Does Video Chapter Marker upload my files to a server?

No. Video Chapter Marker runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Chapter markers let viewers jump directly to specific sections of a video instead of scrubbing through the whole timeline, but adding real chapter metadata (not just a description with timestamps) requires embedding it properly into the video file itself. This tool embeds real chapter markers into a video's metadata, giving you actual navigable chapters supported by compatible players, not just a text list.
