Knowledge Base Advanced Features Ultra Low Latency
How to enable Ultra-Low Latency?


Stream latency is the delay between your camera capturing an event and the event being displayed to viewers. When setting up your live stream, think about how the level of latency may affect your viewers.

If you live chat with viewers, a lower latency is best to reply to viewer comments and questions. Note that with lower latency, your viewers may experience more playback buffering. 

If you don't interact with your audience, a lower latency is not as important.

Why is there a trade-off between latency and quality?

The lower the latency, the less read-ahead buffer the video player will have. The amount of read-ahead buffer is important because it's the main source of stream latency. With a lower latency, viewers are more likely to feel the issues between the encoder and the player.
Network congestion and other factors may also cause live streaming issues, which can delay your stream. Delays can happen even when you have a great network that can sustain your average streaming bitrate.

How to switch to Ultra-low latency?

  • In the Publish section (1) of your LiveU Studio.
  • Enable the Ultra-Low Latency setting (2&3).

If the ultra low latency button is grayed out, please get in touch with your sales rep in order to enable this feature for you depending on the workflow you're trying to achieve.
