real time
Feeds // 0/0 live
The big number is how far behind real time a feed plays (real time = Twitch's timestamp on the video). A new feed starts as received: nothing added, it plays as soon as it reaches us, e.g. −3.6s, and that number floats a little with the connection.
Nudge to add delay. Nudges move from what's playing: +1s turns −3.6s into −4.6s. From then on the feed is locked to Twitch's timestamps and holds steady. If the channel later arrives later than that, the number floats again and shows late in amber.
Syncing players: streamers often run their own stream delay, which we can't see, so line them up by eye in Multiview: pick a moment every POV shows and nudge until it lands together. The slowest streamer gets the lowest delay; faster ones get more. Lowering a delay jumps forward within seconds; raising one freezes that output until the time has built up.
