Movie database links

Used for exact Commentary lookup from sites such as Letterboxd.

Shared movie source (optional)

Paste a YouTube, OK.ru, direct video, HLS/m3u8, DASH, or magnet address. You can also upload a .torrent metadata file. Each participant plays from the provider or swarm; Clapboard does not relay movie bytes.

Video address or magnet link

Or choose a .torrent file Torrent playback joins the swarm from each viewer's browser and exposes their peer connection address to that swarm. Browser v1 reaches WebTorrent/WebRTC peers and web seeds; conventional BitTorrent peers require a bridge.

Copy protect media
Prevent Clapboard's built-in “Use Media” action from creating another Commentary with this shared movie source. This is a Clapboard policy, not DRM.

Scheduled watch party (optional)
