Using Backtrack on SE.Live Canvas (Replay Buffer Guide)

Updated

Purpose: This article explains how to use the Backtrack (Replay Buffer) feature on SE.Live custom canvases, highlighting the differences from native OBS functionality and noting key resource considerations.

Prerequisites:

  • Latest SE.Live version (Build .477 or later)

  • Custom canvas created in SE.Live

  • OBS Studio 31.x or newer installed 

 

What is Backtrack (Replay Buffer)?

Backtrack allows you to save recent moments from your stream retroactively by continuously recording into a temporary buffer. This is perfect for capturing highlights or unexpected moments.

Backtrack Availability

  • On OBS (Native):

    • The replay buffer can run while streaming or offline.

    • Available globally, no canvas-specific configuration needed.

  • On SE.Live Canvas:

    • As of Build .477, available on custom canvases in SE.Live.

    • Only functions while streaming.

Resource Usage Warning

  • Backtrack always consumes encoding resources when enabled, even if the canvas is not currently streaming.

  • Recommendation: Do not use buffers longer than 180 seconds, as extended use can significantly impact system performance.

  • Only enable Backtrack on canvases where it’s truly needed.

 

How to Enable Backtrack on SE.Live Canvas

  1. Enable Backtrack Per Canvas:

    • Click the canvas settings gear icon.

    • Enable Backtrack under the specific canvas options.

    • Save the changes.

  2. Start Streaming:

    • Backtrack will only function while a canvas is actively streaming.

Setting a Hotkey to Save Backtrack Replays

  1. Ensure streaming is active.

  2. Open OBS Hotkey Settings.

  3. Locate the entry:
    "Save Replay" under
    Canvas Backtrack (Replay Buffer): [CANVAS NAME]

  4. Assign your preferred hotkey and save.

ℹ️SE.Live remembers hotkey assignments for each canvas.
⚠️Backtrack will only work while streaming.
⚠️ Enabling backtrack will use encoding power even when idle.
