How to set up Instant Replay feature in OBS Studio

Thanks to the relentless efforts of volunteers, OBS Studio now includes powerful functions from programming. And this gave birth to a very interesting feature: Instant Replay.

This tutorial will examine how to set up Instant Replay in OBS Studio. It can be set in the same scene with gameplay (Gameplay is all the player can do in the game) or your main video, or even configured to be used in a separate scene for Immediate transition.

Request:

Update / install OBS Studio version 21.xx.xx

1. Open the OBS Studio settings section , go to the Output section and check the box " Enable Replay Buffer ".

Set your desired time length.

Note: The longer the time for Replay buffer, the more memory you need. This tutorial will set the time to 10 seconds.

2. In the General settings section , select Automatically start replay buffer box when streaming .

3. In the Hotkey settings section , set hotkey (hot key) to save the Replay buffer. This tutorial will use Ctrl + Shift + S as hotkey.

Using this hotkey, you can still save normal replays, even when installing Instant Replay.

4. Now, close the settings page and start with the Replay Buffer by clicking on the " Start Replay Buffer " at the bottom right of the OBS Studio.

5. Add a new media source to the current scene, call it "Instant Replay" in this tutorial and select the Replay buffer file.

By default it will be placed in the "Video" folder and the file name will start with Replay.

6. At the top of OBS Studio, click Tools, then select Scripts and select "instant replay.lua"

7. From the drop down Media Source menu , select the media source you just added to the scene. Then click Close.

If the media source does not appear, click the refresh icon on the left.

8. Open OBS Studio settings again and go to the Hotkeys section . There will be a new hotkey, called "Instant Replay".

For this tutorial, we will set hotkey to Ctrl + Shift + R.

9. Now, the Instant Replay feature is ready to use. Just press the hotkey combination you just selected and the last 10 seconds will play in the media source. Now, you can resize the source and move it around.

If you have a control device like a Stream Deck, you can create a hotkey action, set up hotkeys just like in OBS Studio, and then, you can use the Instant replay feature with just one button. .
