Live Stream Latency Modes

Stream with confidence by choosing the right latency option for your live events

Updated today

Live streaming brings your content to audiences in real-time, but the technical process of delivering video over the internet introduces a delay between what happens on camera and what viewers see on their screens.

Understanding and selecting the appropriate latency mode is crucial for creating the optimal viewing experience based on your content type and audience needs.

📝 NOTE: Latency Mode options are only available when streaming via third-party software using RTMP. These settings do not apply to Uscreen Live Studio or Zoom integration streams.

Understanding Live Stream Latency

Latency refers to the delay between the moment content is captured on camera and when viewers actually see it on their screens.

ℹ️ INFO: This delay occurs due to the technical process of transmitting video data across the internet.

The complete journey of your video stream includes:

  1. Input Source (Camera)

    • Captures raw audio and/or video

  2. Encoder

    • Compresses the raw feed and wraps it in a stream format

  3. Ingest/Media Server

    • Receives the live feed, validates it, may transmux, and hands it off for processing

  4. Transcoder

    • Creates multiple renditions/bitrates and enforces settings like resolution, fps, and keyframe cadence

  5. Origin/Packager

    • Packages segments, and manifests/playlists, and serves as the source of truth for distribution

  6. CDN (Content Delivery Network)

    • Caches and delivers segments/playlists globally with low latency

  7. Viewer’s Player/Device

    • Requests the manifest, chooses the best rendition based on network conditions, downloads segments, decodes, and plays

  4. Select your preferred option: Standard, Reduced, or Ultra-low

  5. Click Save


Selecting the Right Latency Mode

Standard Latency (20-30 seconds)

Recommended for: Performances, lectures, or any content where viewer interaction isn't time-sensitive.

Pros:

  • Most stable streaming experience

  • Highest compatibility with all devices

  • Better for viewers with slower internet connections

  • Ideal for one-way broadcasts where immediate interaction isn't critical

Cons:

  • Longer delay makes real-time interaction challenging

Reduced Latency (10-15 seconds)

Recommended for: Webinars, educational content, and events with moderate interaction needs.

Pros:

  • Better balance between low delay and stable playback

  • Good for semi-interactive content

  • Compatible with most devices

Cons:

  • May experience occasional buffering on slower connections

  • Still has noticeable delay for truly real-time interaction

Ultra-Low Latency (5-10 seconds)

Recommended for: Interactive Q&A sessions, live coaching, and events where immediate feedback is crucial.

Pros:

  • Closest to real-time streaming available

  • Best for immediate viewer feedback and interaction

Cons:

  • May cause buffering for viewers with weaker connections

  • Uses CMAF format, which isn't compatible with all devices (like Google Chromecast)

  • Requires more bandwidth and stable internet connections

⚠️ WARNING: Geographic location can also impact latency regardless of your settings. If you're streaming from a location far from our ingest servers, even Ultra-Low Latency may not provide significant improvements.


FAQs

Will reducing latency affect my stream quality?

Yes. Lower latency means less buffer time, which can lead to more interruptions for viewers with unstable internet connections.

What if I need real-time interaction but also stable streaming?

Consider using a hybrid approach: stream with Standard latency for stability, but offer a separate Zoom link for viewers who want to interact in real-time.

Which latency setting is best for fitness classes?

For fitness instruction where form correction is important, Reduced latency offers a good balance. However, if your audience includes older or less tech-savvy members, Standard latency may provide a more reliable experience.
