(ENG) Before You Begin

Checking Network Status 

When the venue construction is completed, the first thing to do is check the network connection status of the devices before operating the 4DReplay & 4DLive service. In 4DDM, the connection status of devices such as camera, PC, and Switch is all green to check whether the connection is normal.

• If there is a device whose status is not green, proceed with the ping test to the IP of the device
  (see the Main Ping Test section below for details on the ping test method)

• If the ping connects normally, but does not turn green, check the Daemon activation (see the Daemon Activation section below for details on how to check
  the Daemon Activation)

Camera Property Adjustment 

After checking the connection status of the network device, it is necessary to check whether the camera's focus, color, and exposure are normal, unified, and well set for each sports environment. When building a pre-venue, if the camera is focused on through the Live View or Direct Monitor connection, check whether the camera properties are unified or need to be modified separately in the Software step, and then adjust the camera property of the 4DDM Tab.

• Recognize in advance the part that should be unified and the part that should be different due to the characteristics of the camera position
  and modify it (for details in the step of adjusting the camera properties, refer to the Camera Property section above)

• When the camera property settings for the entire venue to be photographed are completed, click the Property Save button at the top of the Camera Property View to recommend saving the property information (use the Load button to load the property information afterwards)

Calibration

As the final step in Before You Begin, Calibration is an essential pre-stage before you start editing your video. Before operation, it is necessary to check whether calibration data is registered or whether calibration is properly set. Calibration is performed using the calibration function of the 4DDM Tab.

• Click the Record button to simultaneously shoot
  images of all cameras facing the reference bar (All data related to calibration : C:\4DReplay\Calibration)

• Select the Calibration Type of 2D or 3D or 2D + Position Tracking on the photographed image and set the Point to the desired point (refer to the Step of Calibration section above for the steps to set
  the Point according to the Calibration Type)

• After completing all calibration courses, run the 4DPD program to perform 4DREPLAY Services
