Sending a friend a YouTube link works fine until you both hit play. One person pauses to grab a drink, someone has a slower connection, and within a minute you are 20 seconds apart and talking past each other. A SyncUp room keeps the timing aligned instead. When anyone plays, pauses, or seeks, that change is sent to everyone over a WebSocket and the room lands back within about 200ms. The video still streams from YouTube at full quality, since SyncUp syncs the timing rather than re-streaming or compressing the picture.
There are three ways to add something. You can paste a video URL, search YouTube from inside SyncUp without opening a new tab, or import a whole playlist into a shared queue. The queue is handy for a series, an album, or a long mix where you do not want to stop and pick the next video every few minutes. Rooms also have playlist voting and roles (host, moderator, viewer), so a group can decide what plays next without one person controlling everything.
