If your system includes Vicon video cameras, you can check your data accuracy by comparing optical capture data with supported video data. You do this by overlaying the 3D data onto the video (.vvid or .mov) data.

Shogun Post supports the following types of video files:

.vvid files captured from Vicon Shogun Live using Vicon Vue cameras
.mov files that have been transcoded using Shogun Post or the standalone ViconVideoConverter tool (a command line tool that is installed with Vicon Video Viewer, by default to C:\Program Files\Vicon\ViconVideoViewer).

To overlay 3D data onto video files in Shogun Post:

Ensure that the video files are in the same folder as the required 3D data (.x2d or .mcp) file. If a different path was defined during capture (often an SSD per pair of cameras), use the batch transcoding feature of Shogun Post to ensure the files are moved to the correct location. For more information, see Transcode video files.

Tip: If video files are kept in a different folder from the 3D data files, when you load an . x2d or . mcp file, Shogun Post warns you that the video files cannot be located. To manually specify the video file path, in the Selection panel (or 3D Scene view) select the video camera, then in the Attributes panel, expand the Video (Offline) section and set its Video_File attribute to the path of the file. This change is saved when you save the scene in Shogun Post.
Open the .x2d or .mcp file (either from the Data Management panel, or click Import on the File menu, or drag and drop the relevant file from Windows Explorer, as described in Load mocap data files into Shogun Post).
The video files are automatically loaded.
In the Selection panel, expand the System node and click the required camera.

At the top left of the view pane, click the current View type button, and then click Cameras.
At the top of the Cameras view, select View Filters.
Ensure the 3D check box is selected.

The video for each Vicon video camera is displayed in a 3D overlay.

Video is in black and white or color, depending on the video camera used.
To see the image plane of the camera corrected for lens distortion, select Distort 3D.

The 3D overlay should line up with the subject in the Cameras view and the grid should line up with the floor.

You can zoom and pan the video using normal Cameras view controls.

You can select or clear the View Filters to control which 3D elements are displayed.
