Intro

This tutorial will guide you through the necessary steps to record tracking data with Captury

Step 1: Check the Physical Set Up

1. Make sure to close the curtains (and windows) in the DBL (if the light situation changes you will have to re-capture the background again) calibration tutorial

2. Make sure the cameras are on by checking that the switch is plugged in and green lights are on (photo 1.1)

3. Turn on and use the computer on the lefthand side (see photo 1.2)

1. In case you do not know the password for the user login, ask a person who does

2. Open/Select the console

2. Start the Captury tracking software from the console by typing captury (see photo 2.1)

There are currently two different versions of The Captury installed
If you want to work with the old version, type captury in the console
If you want to work with the new version, type captury-new in the console

2. Have your performer stand in the performance platform area with their arms out (see photo 4.2)

3. Click and hold on <new> from the active skeleton area (this will create a new skeleton), drag it onto the person you wish to track on camera and release (see photo 4.3)

4. If it worked, the skeleton should be following the movements of your performer pretty accurately.

After placing the <new> skeleton is on your performer, name it appropriately by right clicking
All the previous non-active skeletons are saved in the searchable area above

4. If the sketelon does not apply properly to the performer, or you are having latency problems, select the Low Latency option and ensure that Quick Scaling is checked (see photo 4.1)

5. If you wish to view advanced options for skeleton optimization, click the advance option icon near the top right of the screen. It looks like a Cog and is next to the X (see photo 4.1)

STEP 5: Recording Tracking Data/Motion

Once the tracking skeleton has been properly applied to your performer, you are ready to record the tracking data

1. Create or select a folder from the area at the bottom of your screen where your tracking data will be recorded. You can also use the "Browse" function to create new folders and locations (see photo 5.1)

2. Ensure that the Record Motion Box has a checkmark in it. If you wish to record normal video from the cameras, ensure that Record Videos is checked as well (see photo 5.1)
