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

**To set the timecode:**

1. Ensure that the Lock is connected into your Vicon Markerless system.
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.
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.
5. 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:

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