Instant Replay (Editor-Only)

Save the last N seconds of Play Mode directly to MP4 using ffmpeg.

Highlights

  • Press F9 to capture the previous N seconds
  • Direct MP4-only pipeline
  • Background encoding (no Editor freeze)
  • Timestamped filenames, no overwrite
  • Editor-only; perfect for debugging clips & quick shares

Setup

  1. Add InstantReplayCapture to your main camera.
  2. Ensure one AudioListener exists in the scene.
  3. Pick resolution, FPS, buffer seconds, and output folder.
  4. Enter Play Mode and press F9 or use the Editor window.
Unity Asset packages cannot include executables. ffmpeg is not bundled; follow the steps on the right to install it once.

Install ffmpeg (Required)

Instant Replay uses ffmpeg to encode MP4 files. Download it once and either place it in the asset’s FFmpeg folder or point the Inspector to its path.

Download

Go to the official Windows builds:

https://www.gyan.dev/ffmpeg/builds/

  • Download the latest release ZIP (e.g. ffmpeg-release-essentials.zip)
  • Unzip it and find bin/ffmpeg.exe

Use it in Unity

  • Option A (auto-detect): Copy ffmpeg.exe to
    Assets/InstantReplay/FFmpeg/ffmpeg.exe
  • Option B (custom path): In the InstantReplayCapture Inspector, set the ffmpeg Path to your exe (e.g. C:/Tools/ffmpeg/bin/ffmpeg.exe)
After this one-time setup, you’re good to go — no need to repeat for future projects if you keep a shared location.

Notes & Tips

  • If UI doesn’t appear in the recording, set your Canvas to Screen Space - Camera.
  • Large buffers and high resolutions use more RAM — start with 1280×720 @ 30 FPS and a 10–20s buffer.
  • The Instant Replay window overrides Inspector seconds/output for that save only; F9 uses the component’s values.
