# Lower-Latency HLS Output with Configurable Buffer Depth

> HLS playback now starts faster and stays closer to live, with configurable buffer settings to balance latency against playback reliability.

We've tuned HLS output for lower live latency without compromising playback reliability on variable networks. Players see content sooner at channel start, and you have direct control over the latency-versus-buffer tradeoff for your specific audience.

Faster player start-up — The master manifest is now available immediately at channel start, so players see the full variant list right away instead of waiting for the first segment.
Configurable live window — Choose how many segments to keep in the live window, letting you tune for lower latency or deeper buffering depending on your viewers' network conditions.
Faster manifest updates — Segment list changes propagate quickly, so players pick up new content sooner on their next poll.
Smoother program transitions — Upcoming content is staged further in advance, reducing the chance of hiccups at program boundaries.
