# Minimize the end-to-end delay for contribution

In feed templates for contribution use cases, the default configuration for the **Live Encoder** service is already optimized for low delay.

If a Multiplexer service is present, this will add delay. If optimizing for low delay, consider whether a Multiplexer service is required.

If a Multiplexer service is required, delay can be reduced by adjusting the following parameters in the [Mux Advanced Settings](/beam/multiplexer/parameters/stream-processing#mux-advanced-settings) section:

* Input jitter buffer latency can be reduced to a minimum of 40 ms.

* If not using encryption, Scrambling latency can be reduced to a minimum of 10 ms.

* If using ASI output with a Dektec 2174b or 2178 card, ASI output buffer latency can be reduced to a minimum of 50 ms.
