Click Start. We do the rest.
Server-side recording for every live class — captured by LiveKit's egress workers, encoded at 1080p, uploaded directly to your Cloudflare R2 bucket. The instructor gets an email the moment the MP4 lands. No browser to keep open, no FFmpeg to run, no transcoding service to set up.
The recording survives a closed laptop.

Player + library
Watch the way you actually watch lectures.
Speed control, chapter navigation, resume-where-you-left-off, searchable transcripts, and a list that knows what you’ve already watched.
Auto-generated chapters
Transcript-derived chapter markers parsed from transition phrases (“Now let's talk about…”, “Moving on to…”). Click to seek. 5–12 chapters per recording, ≥90s spacing so you never get a chapter cluster.
Playback speed
0.75× / 1× / 1.25× / 1.5× / 2× chips below the video. Speed persists across recordings — set 1.5× once, every video opens at 1.5×.
Resume from last position
Player remembers where you stopped. Open it again → ‘Resume from 12:34?’ overlay. Watched-90% trips the Completed badge.
Class chat in the recording
Side-channel chat from the live class persists alongside the video. Re-watchers see the questions that came up in real time, not just the lecture.
Watch-state filters
Unwatched / In progress / Watched chips on the recordings list, with live counts. Slice a 40-recording backlog down to the 8 you haven't started yet.
Visibility tier filter
Filter the list by who can see each recording — Public, Enrolled, Community, or Link only. Self-hides on workspaces where everything is set to the default tier.
