What you need to know
A replay buffer is a local recording that runs in a loop. New footage replaces the oldest footage until you press the hotkey. ReplayBox then saves the moment that has already happened, and the source recording stays on your computer.
How loop recording works
Regular recording requires pressing Start before an event and then finding the relevant clip in a long file. A replay buffer continuously keeps the selected interval, such as the last few minutes, updating it in a loop.
When an important or disputed event happens, press the assigned key. The app saves the accumulated interval as a separate recording. This suits unpredictable situations such as a rule violation, technical error, rare game event or successful play.
What to configure before playing
Before your first session, check not only the buffer duration but also which screen and audio sources are recorded. A short test saves time when you actually need the footage.
- Choose a duration that provides enough context before an event.
- Check the video source, resolution and frame rate.
- Make sure game audio is recorded at the right volume.
- Assign a hotkey that does not conflict with game controls.
- Check free disk space and the folder used to save source files.
What to do after saving a moment
Review the saved clip promptly to make sure it shows the start, participants' actions and outcome. If the footage is for project administrators, you can remove unnecessary minutes in ReplayBox's built-in editor.
After trimming, add timestamps to key moments and publish the content. Instead of sending a large file, you get one link to a viewing page with clear navigation.

Questions and answers
Do I need to start recording before the event?
You need to start the buffer in advance, but you don't need to save a separate file before the event. Press Save after the moment you want.
Is the source recording uploaded to the cloud immediately?
No. The content is saved locally first. Uploading starts only after preparation and an explicit publish command.
Does a replay buffer replace a full-session recording?
Not always. Regular recording is more suitable for a long session planned in advance. A buffer is useful specifically for unexpected short episodes.
