--- title: "MCP review in Shogun Markerless" canonical: "https://help.vicon.com/space/ShogunMarkerless121/1253507096/MCP%20review%20in%20Shogun%20Markerless" format: markdown --- > Macro (anchor) Shogun Markerless 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 Shogun Markerless. When you’ve finished reviewing the take, you can immediately resume capturing. > ℹ️ **Note** > ℹ️ Shogun Markerless 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. **To review takes in Shogun Markerless:** 1. Ensure that you have at least one take in the Session folder (see [Capture a take](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507095) and [Create a folder hierarchy to store captures](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507126)). 2. In the **Review **panel (**View** menu > **Review**), go to the **Captures** section and click the name of the required take. 3. If required, change the **Description** and **Notes** fields at the bottom of the Review panel. 4. To review the selected take, double-click the row. At the top of the Shogun Markerless window, in the center of the menu bar, the words **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. 5. To play through the take, use the Play/Stop button > Macro (inline-media-image) and the Go to beginning > Macro (inline-media-image) and Go to end > Macro (inline-media-image) 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)). 6. To close review mode and return to capturing, click the exit button to the right of the take title in the menu bar.

For more information, see *[Load mocap data files into Shogun Post](https://vicon-help.atlassian.net/wiki/spaces/ShogunPost121/pages/1253739058)* and *[Export from Shogun Post](https://vicon-help.atlassian.net/wiki/spaces/ShogunPost121/pages/1253736812)* in *Getting started with Vicon Shogun Post*. The following topics describe alternative ways to review your data. > Macro (toc) > Macro (scroll-pagebreak) ## > Macro (anchor) Streaming via Vicon DataStream SDK The current data in Shogun Markerless is served to Vicon DataStream SDK clients over port 801, so that MotionBuilder and Unreal show the reviewed clip when you click **Enter Review**. This is the standard pipeline. > ⚠️ **Note** > ⚠️ When viewing data in Review mode, 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. This is also the standard pipeline. Low latency data is streamed over port 804 – this pipeline is the **ObjectTracker** pipeline. This data includes objects tracked using the **ObjectTracker** functionality, which ensures low latency. > Macro (scroll-pagebreak) #### Monitor datastream connections in the Connections panel Shogun Markerless enables you to display the current connections for the datastream ports. To do this, from the **View** menu, select **Connections** to display the **Connections **panel. > ![Connections panel in Vicon Shogun Markerless, showing Current Connections section.](media://b86c3c09-ec2f-4a4a-bdc8-71b93523f402) The following data is streamed over the ports. - **801** : Standard pipeline. This is the full output and includes live data, paused live data, and review data. :check_mark: **Tip**: To pause live data, click **Enter Review** to the right of the timeline. - **804** : ObjectTracker pipeline. This output is for low-latency data for rigid objects only. No subjects. - **8802** : Standard pipeline. This is the full output, live only, with no pausing. ## MCP review via Shogun Markerless SDK You can launch and control MCP review using the Shogun Markerless SDK. For more information, see the Shogun Markerless SDK sample script included in the API package (by default installed in *C:\Program Files\Vicon\Shogun Markerless1.##\SDK\*) and the information in the supplied code. The sample script (*playback.py*), enables you to open an MCP for review in Shogun Markerless by specifying a capture name, as shown in the following example, or just to review live data if no name is specified. `python playback.py --name Jack_Fin_2019-10-15_17-19-26` > Macro (scroll-pagebreak) ## Review Vicon video files You can check your reference footage against what was captured, including any overlay of the 3D mesh. To do this: 1. Load an .*mcp* file with video data into MCP review (see [MCP Review in Shogun Markerless](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507096/MCP+review+in+Shogun+Markerless#MCPReview)). 2. In the **Review** panel, in the **Review Options** section, make sure **Load Video Data** is selected (the default). 3. Play or scrub through the review of the capture. ## 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: 1. Load an .*mcp* file into MCP review (see [MCP Review in Shogun Markerless](https://vicon-help.atlassian.net/wiki/spaces/ShogunMarkerless121/pages/1253507096/MCP+review+in+Shogun+Markerless#MCPReview)). 2. Ensure the **View Filters** are set as required. 3. Play or scrub through the take and review the raw data as required.
