RecBox
RecBox
Screen recording for Windows — without the OBS complexity. Capture a monitor at native resolution, with optional mic and system audio. No streaming. No scenes. No clutter.
Features
Minimize to tray
Hide from the taskbar while recording so RecBox never appears in your video.
Native monitor capture
Pick any display. Output matches that monitor’s real resolution — no scaling.
Mic + system audio
Toggle each independently. NVIDIA Broadcast shows up as a normal mic when installed.
Simple quality presets
Low file size, Balanced, or Maximum quality — with hardware encode when available.
Modern desktop UI
Clean dark interface with a one-click record control. Settings save automatically.
Never lose a take
Crash-safe files, automatic resume if capture is interrupted, and recovery of unfinished recordings on next start.
Easy to run
One PowerShell script downloads FFmpeg, builds, and launches. Or publish a portable folder.
Install & update
Installers place RecBox under %LocalAppData%\Programs\RecBox (no admin),
create Start Menu shortcuts, and bundle FFmpeg.
Your settings stay in %AppData%\RecBox across upgrades.
Setup.exe
Download RecBox-*-Setup.exe from
GitHub Releases and run it.
New versions: run the newer Setup — settings are preserved.
Zip + PowerShell installer
powershell -ExecutionPolicy Bypass -File .\Install-RecBox.ps1 -FromZip .\RecBox-1.1.0-win-x64.zip -DesktopShortcut -Launch
Or install/update from the latest GitHub Release:
powershell -ExecutionPolicy Bypass -File .\Install-RecBox.ps1 -FromGitHub -DesktopShortcut -Launch
Developers — build packages
build-installer.cmd
Setup.exe. For day-to-day coding use run.cmd
(bypasses PowerShell execution policy). Or:
powershell -ExecutionPolicy Bypass -File .\run.ps1.
Requirements
- OS: Windows 10 or 11 (64-bit)
- End users: no .NET SDK needed (self-contained build)
- To build installers: .NET 8 SDK; optional Inno Setup 6 for Setup.exe
- Optional: NVIDIA / AMD / Intel GPU for hardware encoding; NVIDIA Broadcast for mic
How to record
- Choose a monitor — native resolution is shown in the list.
- Microphone (optional) — Default, a specific device, or NVIDIA Broadcast.
- System audio (optional) — capture what your PC plays; independent from the mic.
- Quality — Low file size, Balanced, or Maximum quality.
- Press Start — the big teal control. Timer begins.
- Hide to tray — minimize or close so RecBox leaves the taskbar.
- Stop from the app or tray menu. Open folder to find your MP4.
System tray
Minimize or close the window to send RecBox to the tray (next to the clock). Recording continues in the background without appearing in the capture.
- Double-click the tray icon to restore the window.
- Right-click for Show, Start/Stop, or Exit.
- Use Exit when you want to quit completely.
Troubleshooting
FFmpeg was not found
Run run.ps1 or tools/download-ffmpeg.ps1, or place ffmpeg.exe in tools/ffmpeg.
No microphone / NVIDIA Broadcast missing
Check Windows Sound settings. Install/enable NVIDIA Broadcast, then restart RecBox.
System audio silent or disabled
You need an active playback device (speakers/headphones) set as default. RecBox uses WASAPI loopback — no virtual cable needed.
Black screen in games
Try borderless windowed mode. Elevated windows may need RecBox run as Administrator.
Where are my files?
Default: %UserProfile%\Videos\RecBox. Use Open folder in the app.
RecBox or the PC crashed while recording
Start RecBox again — it finds the unfinished recording and saves it as MP4 automatically
(“Recovered from last session”). If conversion is impossible, the playable .mkv is kept.
The status says “Recording resumed”
Capture was briefly interrupted (UAC prompt, lock screen, display change). RecBox resumed on its own and all parts are joined into one file; a short gap may appear at that moment.
Reporting a problem
Attach the log from %AppData%\RecBox\logs.
