To ensure optimum recognition of subjects and markers, you adjust the camera settings in Shogun Markerless.

## Optimize markerless camera settings

1. In Vicon Shogun Markerless, view video data from your markerless cameras in one or more **Cameras** views. (To display the necessary layout, click the View settings > Macro (inline-media-image)

 in the menu bar, then click **System Setup**.)
2. Ensure you can clearly see images moving in each **Cameras** view.
3. In the **System** panel, click **Vicon Markerless Cameras** to select all the cameras, go to the **Video Setup** section below, ensure the advanced settings are displayed > Macro (inline-media-image)

 and adjust the following camera settings as necessary:
  - **Shutter Duration**: If the images are too dark or too light, adjust this setting.
  - **Gain**: In most cases, leave the setting at the default of 1x to ensure images are bright enough to see clearly. If adjusting the Shutter Duration doesn't sufficiently improve the image, and the images appear too faint, adjust this setting.
4. If you need to further adjust any of the above settings for individual cameras, in the **System** panel, click the name of the relevant camera and change the required setting(s) in the **Video Setup** section.
5. When you have finished focusing and optimizing the cameras, depending on your Vicon Markerless system, choose the next step:
  - If your system includes optical cameras, see [Optimize optical camera settings](#OptimizeOptical); or
  - If your system includes only markerless cameras, if required, go to [Set timecode (optional)](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507216) or if not, proceed straight to [Calibrate cameras](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507088).

## Optimize optical camera settings

1. In Vicon Shogun Markerless, make sure you are viewing 2D data from your optical cameras in one or more **Cameras** views. (To display the necessary layout, click the View settings > Macro (inline-media-image)

 in the menu bar, then click **System Setup**.)
2. Have someone wave the calibration device around in the capture volume and ensure you can see marker images moving in each **Cameras** view.
  
3. In the **System** panel, click **Vicon Cameras** to select all the cameras, go to the **Optical Setup** section below, ensure the advanced settings are displayed > Macro (inline-media-image)

 and adjust the following camera settings as necessary:
  - **Gain**: To start with, leave the setting at the default of 1x to ensure 2D marker images are bright enough to see clearly. If the markers appear too faint or if the cameras have trouble distinguishing them, adjust this setting.
  - **Threshold**: A good starting value is 0.2 to 0.3. This setting determines the minimum value at which data is registered by pixels on the camera sensor and considered for circle fitting. As this setting acts like a high-pass filter, reducing this value increases the data that can pass through the sensor.
  - **Strobe Intensity**: Adjust this setting to increase the effective brightness of the strobe and therefore the distance at which and clarity with which it is likely to illuminate. A good starting value is 1.0 (100%), which is why this is the default setting.

If you need to further adjust any of the above settings for individual cameras, in the **System** panel, click the name of the relevant camera and change the required setting(s) in the **Optical Setup** section.

When you have finished focusing and optimizing the cameras, with all optical cameras selected, in the **Optical Setup** section change **Grayscale Mode** back to **Auto**.

Depending on whether you need to set a timecode, proceed to the next step:

- If required, go to [Set timecode (optional)](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507216); or
- If a timecode is not required, proceed straight to [Calibrate cameras](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507088).
