Prerequisites

This quickstart assumes:

• You have the Azure Kinect DK connected to your host PC and powered properly.
• You have finished setting up the hardware.

Create recording

1. Open a command prompt, and provide the path to the Azure Kinect recorder, located in the installed tools directory as k4arecorder.exe. For example: C:\Program Files\Azure Kinect SDK\tools\k4arecorder.exe.

2. Record 5 seconds.

   k4arecorder.exe -l 5 %TEMP%\output.mkv

3. By default, the recorder uses the NFOV Unbinned depth mode and outputs 1080p RGB at 30 fps including IMU data. For a complete overview of recording options and tips, refer to Azure Kinect recorder.

Play back recording

You can use the Azure Kinect Viewer to play back a recording.

1. Launch k4aviewer.exe
