Chat velocity

Chat velocity is the rate at which messages arrive in a live chat — messages per second. A sudden spike in chat velocity is one of the strongest signals that something clip-worthy just happened on stream.

When a streamer hits a clutch, lands a joke, or a moment gets heated, the chat reacts before any audio or visual model would flag it. ClipMe treats chat velocity as a first-class signal, weighting those spikes alongside loudness and scene-change density when it scores each second of a VOD. It's a signal upload-first clippers ignore entirely — and a big reason a live-native clipper finds better moments, especially for IRL and Just Chatting streams that have no gameplay to detect.
