Once the capture volume is calibrated and all markers are placed, you are now ready to capture Takes. In this page, we will cover key concepts and tips that are important for the recording pipeline. For real-time tracking applications, you can skip this page and read through the Data Streaming page.
There are two different modes in Motive: Live mode and Edit mode. You can toggle between two modes from the Control Deck or by using the (Shift + ~) hotkey.
Tip: Prime series cameras will illuminate in blue when in live mode, in green when recording, and turned-off in edit mode. See more at Prime Series Status Indicators
Recording in Motive is triggered from the Control Deck when in the Live mode, and the recorded data
In Motive, capture recording is controlled from the Control Deck. In the Live mode, new Take name can be assigned in the name box or you can just simply start the recording and let Motive automatically generate new names on the fly. You can also create empty Takes in the Data Management pane for a better organization. To start the capture, select Live mode and click the recording button (red). In the control deck, record time and frames are displayed in (Hour:Minute:Second:Frames).
Tip: For Skeleton tracking, always start and end the capture with a T-pose or A-pose, so that the skeleton assets can be redefined from the recorded data as well.
In Motive, all of the recorded capture files are managed through the Data Management pane. Each capture will be saved in a Take (TAK) file, which can be played back in the Edit mode later. Related Take files can be grouped within session folders. Simply create a new folder in the desired directory and load the folder onto the Data Management pane. Currently selected session folder is indicated with the flag symbol (), and all newly recorded Takes will be saved in this folder.
Tip: Efficient ways of managing Takes
When a capture is first recorded, both 2D data and real-time reconstructed 3D data is saved onto the Take. For more details on each data type, refer to the Data Types page.
Throughout capture, you might recognize that there are different types of markers that appear in the 3D perspective view. In order to correctly interpret the tracking data, it is important to understand the differences between these markers. There are three different displayed marker types: markers, rigid body markers, and bone (or skeleton) markers.
Marker data, labeled or unlabeled, represent the 3D positions of markers. These markers do not present rigid body or skeleton solver calculations but locate the actual marker position calculated from the camera data. These markers are represented as a solid sphere in the viewport. By default, unlabeled markers are colored in white, and labeled markers will have colors that reflect the color setting in the rigid body or the corresponding bone.
Labeled Marker Colors:
Rigid body markers or skeleton bone markers are referred to as Asset Model Markers. They appear as transparent spheres within a rigid body, or a skeleton, and each sphere reflect the position that a rigid body, or a skeleton, expects to find a 3D marker. When the asset definitions are created, it is assumed that the markers are fixed at the same location and does not move over the course of capture.
In order to view asset model markers, both the Asset Model Markers visual aid option in the viewport and the Asset Model Markers property on the corresponding asset must be enabled. This is enabled by default for skeleton assets but this must be enabled for rigid bodies to view them. When the rigid body solver or skeleton solver are tracking from the 3D markers, the marker reconstructions and asset model marker positions will closely align in the viewport.
For rigid body assets, when their asset definition is created, it expects the markers to be fixed in the same location and the object does not deform over the course of capture. Each rigid body is given a acceptable deflection property value. As long as the actual marker position is within the allowable deflection from the asset model marker position, the marker will be labeled. For skeleton assets, as the body segments are not perfectly rigid, some amount of offset from the model marker position is allowed.
