First up, streamers now have the option to enable ultra-low latency, which will bring down streaming video latency to just a couple of seconds. That will make functions like answering questions during a livestream easier and more timely. YouTube has also made moderating chats easier and more efficient. You can now pause a chat feed by pressing "alt/option" and then hover over messages to take them out or approve them. Streamers can also opt in to a feature that will hold possibly inappropriate messages for review. The system, which can learn users' preferences with greater use, will keep identified messages from posting before users can decide whether to approve them, hide them or report them.
YouTube is also introducing hidden users lists that can be shared between moderators and across both comments and live chat as well as the ability to stream directly to the main YouTube app with your iPhone or iPad from any app that supports Apple's ReplayKit. All of the new features are launching today.
