Shogun Live enables you to replay takes as soon as you’ve captured them. MCP review enables you to review a take (.mcp file), update your notes on a take, or investigate technical issues, all without having to leave Live. When you’ve finished reviewing the take, you can immediately resume capturing.

To review takes in Live:

Ensure that you have at least one take in the Session folder (see Capture a take and Create a folder hierarchy to store takes).
In the Review panel (View menu > Review), go to the Captures section and click the name of the required take.
If required, change the Description and Notes fields at the bottom of the Review panel.
To review the selected take, double-click the row.

At the top of the Shogun Live window, in the center of the menu bar, the word Review is displayed, followed by the title of the selected take.
At the bottom of the screen a time bar displays information about the selected take. It shows you the current frame, current timecode and duration.
To play through the take, use the Play/Stop button and the Go to beginning and Go to end buttons to the right of the time bar. You can also press the default A and S hot keys to scrub back and forward one frame at a time (to change hot keys, double-click the relevant line in the Hot Keys dialog box (Shift+H)).
To close review mode and return to capturing, click the exit button to the right of the take title in the menu bar.

Note
Shogun Live is either in capture mode (ie, live) or in review mode for a single take. You cannot view both live and captured data simultaneously, or compare two takes.

Streaming via Vicon DataStream SDK

The current data in Shogun Live is served to Vicon DataStream SDK clients over port 801, so that MotionBuilder and Unreal show the reviewed clip when you click Enter Review.

Note
When viewing capture data in Enter Review, you are viewing just a few seconds of cached data from the captured take.

For clients that require an uninterrupted live output, an additional DataStream SDK server sends the current live data over port 8802.

Low latency data is streamed over port 804. Such data includes objects tracked using the low latency object tracking functionality, for more information see Understand object tracking in Shogun Live.

Monitor datastream connections in the Connections panel

Shogun 1.6 and later enables you to display the current connections for the datastream ports.

To do this, go to the View menu, select Connections to display the Connections panel.

The following data is streamed over the following ports.

801 : Full output, includes live data, paused live data, and review data.

Tip: To pause live data, click Enter Live Review to the right of the timeline.
804 : Low latency, object-only output. No subjects.
8802 : Full output, live only, no pausing.

MCP review via Shogun Live SDK

You can launch and control MCP review using the Live SDK.

For more information, see the Live SDK sample script included in the API package (by default installed in C:\Program Files\Vicon\ShogunLive1.#\SDK\) and the information in the supplied code.

The sample script (playback.py), enables you to open an MCP for review in Shogun Live by specifying a capture name, as shown in the following example, or just review live data if no name is specified.

python playback.py --name Jack_Fin_2019-10-15_17-19-26

For more information on using Python with Shogun, see Python scripting with Vicon Shogun.

Review Vicon Video and SDI video files

You can check your reference footage against what was captured, including any overlay of the 3D mesh. To do this:

Load an .mcp file with video data into MCP review (see MCP Review in Shogun Live).
In the Review panel, in the Review Options section, select Load Video Data. (This option is cleared by default, as performance may be affected in files with multiple video cameras.)
Play or scrub through the review of the take, which includes data from Vue or supported third-party video cameras.

Review raw camera data

You can check raw data for captured takes. This can be useful when troubleshooting or investigating possible issues. To do this:

Load an .mcp file into MCP review (see MCP Review in Shogun Live).
Ensure the View Filters are set as required.
Play or scrub through the take and review the raw data as required.
