The LIVE pill is an example of the in-player latency readout.

Latency

A few seconds, not ten or more.

Embedded web players keep a long buffer and fall well behind the broadcast. ONSET's native player uses Amazon IVS, which is built on the same video technology as Twitch, and keeps you close to the live edge.

  1. 01

    Live happens at the edge.

    The live edge is the newest moment of the broadcast. Everything behind it has already happened.

  2. 02

    Embedded players lag behind.

    An embedded web player keeps a long buffer, so what you see trails the action.

  3. 03

    ONSET rides the edge.

    A short buffer and a smooth catch-up whenever playback falls behind. The measured latency is shown in the player.

Illustration, not a benchmark. The app measures the real delay.
