Set timecode (optional step)

If your system includes an external timecode generator, before you calibrate the cameras, you must set the required timecode in Shogun Live.

To set the timecode:

1. In the System panel, expand the Connectivity Devices section and select your device to view its current settings.

   

2. At the top of theSystem panel, view the system settings.

3. In the Frame Rate (Hz) list, enter the required frame rate.

   Tip: If you're tracking fast-moving props, for best results, choose a reasonably high frame rate (100-120 Hz ) and ensure the rate of dropped frames is minimal.

   (For information about using High Speed mode, which enables you to run Vicon Vantage cameras at a higher frame rate while maintaining the FOV, see High-speed mode section of the Vicon Vantage camera range page, found in the Vicon Vantage Reference Guide.)

4. To use a genlock standard, ensure the Genlock Setup option is selected and from the Genlock Setup list, select the standard you want to use. Similarly, if required, enable the Timecode Setup option and select a timecode standard from the Timecode Setup list. The following example shows the LTC standard and a frame rate of 120 selected:

   

5. In the Genlock and Timecode section for the selected connectivity device, to enable genlock, select Genlock Enabled.

6. In the Timecode Source list, select the required option.

   

7. In the Data Capture panel (by default displayed at the bottom of the Camera Calibration panel, on the right of the Shogun Live window), the timecode is now displayed.

   

   It is also shown as part of the information displayed at the bottom of the Workspace.

   

Use High Speed mode to run Vantage cameras at higher frame rates

Shogun 1.5 and later supports the use of the Vantage+ firmware upgrade (Firmware 725 and later), enabling you to use High Speed mode with your Vantage cameras without having to change the field of view (FOV) or lens. When you capture optical data, subsampling (selectively reducing the pixel count) enables you to run at high camera frame rates without reducing the FOV (frame size). You can change frame rates during capture and you don't need to set up your cameras again when you increase the frame rate, as the FOV is unchanged.

Note that because the higher speeds are achieved through subsampling (removing some pixels from the frames), some reduction in resolution is incurred. For details, see High-speed mode section of the Vicon Vantage camera range page, found in the Vicon Vantage Reference Guide.

To select high-speed mode:

1. In Vicon Shogun Live, in the System panel, select the Frame Rate list and set the system frame rate to the speed you want to use in High Speed mode.

   A warning may temporarily be displayed, alerting you to the discrepancy between the requested frame rate and the actual system frame rate, until you select high speed mode for all the relevant cameras, as explained next.

2. In the System panel, select one or more cameras.

3. In the camera properties below, ensure the Advanced properties are displayed and in the Optical Setup section, select the Sensor Mode menu and select High Speed.

   

4. In the Cameras view pane, notice that the High-Speed mode icon is displayed in the top left corner of the view, next to the other camera details
