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 the**System** panel, view the system settings.
3. In the **Frame Rate (Hz)** list, enter the required frame rate.
  :check_mark: **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](https://help.vicon.com/space/Vantage).)
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](https://help.vicon.com/space/Vantage).

**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 > Macro (inline-media-image)

 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
