New in Motive 2.0

This pane replaces the functionality of the properties section under the Project pane from the previous versions of Motive.

The new Properties pane lists out configured properties of selected assets in Motive. This pane can be accessed by clicking on the icon in Motive.

Rigid body properties shown for the selected rigid body is listed under the Properties pane.

Selected Assets

---

Properties will be listed for the following items, and they are documented in separate pages.

• Properties: Take
• Properties: Rigid Body
• Properties: Skeleton

The default properties for newly created assets can be configured in the Application Settings, Skeleton Pane, or Rigid Bodies Pane.

Properties: Tracking Group (Camera)

---

Tracking group configurable settings.

The following properties can be configured when the Tracking group is selected from the Devices pane. This properties section configures properties for the whole camera system.

Camera Settings

Filter Switch

Sets the camera to view either visible or infrared light on cameras equipped with a Filter Switcher. Infrared Spectrum should be selected when the camera is being used for marker tracking applications. Visible Spectrum can optionally be selected for full frame video applications, where external, visible spectrum lighting will be used to illuminate the environment instead of the camera’s IR LEDs. Common applications include reference video and external calibration methods that use images projected in the visible spectrum.

Automatic Gain Control

Default: False. Automatic Gain Control feature adjust the camera gain level automatically for best tracking. This feature is available only in Flex 3's and Duo/Trio tracking bars.

Video Type

Configures video type for the selected camera. Several modes are available for efficient on-camera image processing. Available modes vary slightly, depending on camera model. Read more from Data Recording page.

Illumination Type

Sets the illumination to either Strobed or Continuous. Strobed illumination will output more light with equivalent power when compared to Continuous and is the ideal choice for standard motion capture volumes. Continuous is ideal for volumes where external IR interference is potentially an issue (e.g. with IR actuated stereovision systems that cannot synchronize to the OptiTrack cameras, or when other volumes may be within line of sight).

Display Options

Name

Sets the name for the selected camera group.

Camera Color

Sets the color for camera group members as they appear in the 3D viewport. Color values are input as standard RGB triplets.

Visible Cameras

Selects whether cameras in the group are displayed in the viewport.

Show Volume

Selects whether the capture volume (defined as capable of tracking a single marker) is displayed in the viewport. Enabling this will allow the volume to be displayed as a wire cage around the ground plane where multiple cameras fields of view intersect. Valid options are True, False (default).

Camera FOV

Selects whether camera FOVs are displayed in the viewport. Camera FOV accurately depicts the frustum angles, while depth is artificially capped. Actual depth may vary depending on camera settings and marker size. Enabling this feature can be beneficial in volume visualization for creation and adjustment. Valid options are True (default), False.

Camera Overlap

Sets the minimum camera overlap necessary for a region to be visualized as part of the capture volume. Higher numbers represent more camera coverage, but they will tend to reduce the size of the visualized capture volume. Valid range is 1 to 25 (default 3).

Volume Resolution

Sets the resolution of the capture volume visualization. A higher number represents a more detailed visualization. Valid range is 1 to 120 (default 50).

Opacity

Sets the opacity of the volume visualization. A value of 1 is transparent and 100 is opaque. Valid range is 1 to 100 (default 100).

FOV Intensity

Sets the opacity of the FOV visualization. A higher value represents a more opaque volume visualization. Valid range is 1 to 100 (default 50).

Advanced

Point Cloud

Indicates which point cloud engine is being used for reconstruct 3D points. Point cloud engine v4.0 provides high quality 3D reconstruction outputs with fast speed computation.

Synchronization Control

Determines how late camera frames are dealt with. Timely Delivery will drop late frames, which is ideal for real-time applications where data completeness is secondary to timeliness. Complete Delivery will hold up processing of frames when a frame is late. Automatic, which is the default and recommended setting, runs in Timely Delivery mode until it gets a non-trivial percentage of late frames, at which point it will automatically switch to Complete Delivery.

Fan Mode

Provides an option to turn off the camera fan during recording, for S250e cameras only.

Shutter Offset

Delays the shutter timing of selected tracking camera group for N microseconds.

Mask Regions

• Mask Width (pixels):

Sets the extra pixel coverage (width) for masking visible markers when the mask visible function is used. A larger number will block a wider grouping of pixels simultaneously. Valid range is determined by the resolution of the cameras.

• Mask Height (pixels):

Sets the extra pixel coverage (height) for masking visible markers when the mask visible function is used. A larger number will block a wider grouping of pixels simultaneously. Valid range is determined by the resolution of the cameras.

Properties: Camera

---

Single camera configurable properties.

The following properties can be configured when a Camera is selected from the Devices pane.

Gain

Sets the gain setting for the selected camera.

Video Type

Sets the video type of the selected camera.

Properties: Force Plate Group

---

Force plate group configurable properties.

The following properties can be configured when Force Plates group is selected from the Devices pane.

Force Plate Group Settings

Units

Default: Metric. Sets the units for displaying force and moment data on the timeline graph.

Threshold

Minimum threshold, in N, force required for the resultant force to be displayed in the view port.

Baseline (frames)

Sets the length of initial recording, baseline, frames to be used as the reference zero samples in C3D files. During the initial frames, no load should be applied to the plates.

Sync Source

Sets the Sync source for the force plates. For now, the force plates (AMTI) only support Free Run mode with manufacture defined sampling rates, read more at Quick Start Guide: Force Plate Setup.

Force Display Scale

Adjusts the size of the resultant force vector displayed in the 3D viewport.
