Introduction
This document explains the preparations and operating procedures required for shooting using the Multi-Camera Orchestration system. Please read it carefully before use and operate the Multi-Camera Orchestration system correctly.
Before Use
This system uses AI technology to detect human bodies and track specified individuals. However, it does not guarantee effective camera control under all shooting conditions. Be sure to test the system in the actual environment before starting operation. Also, ensure that the system is used in an environment where an operator can manually intervene in case of misdetection.
Multi-Camera Orchestration System Overview
The Multi-Camera Orchestration system is a system that, in multi-camera video production, automatically controls multiple sub-cameras in coordination with the camera work of the main camera operated by a camera operator. You can configure framing and the coordination between cameras according to the shooting intent.
The system's operation uses multiple applications. For details, see "System Configuration" (P. 11) and "Applications" (P. 14). For information on operating the cameras and their functions, refer to the camera's User Manual. Also, make sure to complete the cameras' initial settings in advance.
Multi-Camera Orchestration Core Overview
The Multi-Camera Orchestration Core is the application that controls the Multi-Camera Orchestration System. In addition to controlling the behavior of sub-cameras based on settings and the subject's status, it also handles system startup/shutdown and license authentication.
Multi-Camera Orchestration Control Panel Overview
The Multi-Camera Orchestration Control Panel is the application used to operate the Multi-Camera Orchestration System. It handles camera registration to the system, role configuration, camera position measurement, and operations during shooting.

Licensing for the Multi-Camera Orchestration System
The Lite license for the Multi-Camera Orchestration System restricts certain features. Restricted features will be indicated on the Control Panel application screen with Full. To use all features, purchase a Full license and perform license activation. Trial use is also available; in that case, authenticate using a Trial license. For instructions on authentication, see "Authentication Using a Trial License" (P. 18) and "Authentication Using a Paid License" (P. 18).
For Full license users, a license for the remote camera Auto-Tracking Application is required for sub-cameras used. Purchase it separately and perform license authentication. For details, refer to the manual of the Auto-Tracking Application.
Restrictions
- When operating MCO, close all applications other than the applications used for MCO (P. 14).
- When reinstalling or uninstalling applications used for MCO, make sure to close any running applications.
- Communication via an HTTP proxy is supported, but it depends on the environment variables and network settings of the computer running the software.
- HTTP proxy authentication is not supported.
- While MCO is communicating with cameras, the system will not automatically enter sleep or hibernation mode; however, if you manually put the system to sleep or hibernate, it will do so even during communication.
- When launching an application used for MCO, a message such as "Do you want to run this file?" may appear. Click [Run] to continue launching the application.
- In Multi-Camera Orchestration Control Panel, if multiple network cards are used and multiple (non-AutoIP) IPv4 addresses are set on the same computer, communication may not function correctly. In that case, you will need to temporarily reduce the number of IPv4 addresses to one.
- When updating the OS, check your local Canon website for the latest operating environment information.
Getting Started
This section describes the concept of roles and role sets in MCO, the system configuration, and applications.
Roles
In MCO, a "role" defines how you want a camera to behave. When a role is assigned to a camera and the system is operated, the camera behaves according to the settings of that role. The main elements are:
- Configuration of manual camera control (main camera) / automatic control (sub-cameras) / fixed field of view.
- Shooting instructions for automatic control of sub-cameras (shooting target, viewing angle, zoom values, etc.)

![graph TD A["User Interaction"] --> B["Video Display"] B --> C["Video Output"] style A fill:#f9f,stroke:#333 style B fill:#ccf,stroke:#333 style C fill:#cfc,stroke:#333 subgraph (1) Video D["User Interaction"] E["Video Display"] end subgraph (2) MCO F["User Interaction"] G["Video Display"] H["Video O…](/content/2026/08/1630012/images/00ba6844f32fbe6e6b63160c3981f9e23789e412081650f38523403f8a67edfd.jpg)
(1) The operator of the main camera changes the framing. The main camera zooms in on subject A.
(2) MCO automatically controls the framing of the sub-camera according to the set role. Zooming in on sub-camera subject B.
By setting the "Role," you can automatically maintain the same framing as the main camera.
In MCO, a "Role Set" refers to a grouping that links cameras used for shooting with their assigned roles. In the Control Panel application, multiple role sets can be saved in advance. During shooting, you can switch between role sets to flexibly change camera roles according to the scene.

■ Overhead Camera Installation
- Two overhead cameras must be installed and connected to MCO. Configure the "shooting range" and "stage area" in advance. For details, refer to "Stage Settings" (P. 26).
• Install the cameras so that the "shooting range" fits within the fixed viewing angle. - Position each overhead camera so that the "shooting range" is captured as large as possible within the viewing angle. If the "shooting range" is too small relative to the overhead camera's angle, the tracking performance of the subject may decrease.
- Ensure that subjects do not overlap within the overhead camera's viewing angle.

Note
By installing the overhead camera above the subject, you can avoid subject overlap.

■ Main Camera/Sub-Camera Installation
The number of main/sub-cameras that can be connected to MCO depends on the type of license in use.
| License Type Number of Cameras |
| Full License 1 main camera, 4 sub-cameras |
| Lite License 1 main camera, 3 sub-cameras |
Position the cameras so that each camera's subject is fully within the camera's angle of view.
■ iPhone Mounting for the Main Camera
If the main camera is a digital cinema camera, video camera, or a system camera, mount an iPhone with Multi-Camera Control installed onto the main camera. Place the iPhone in landscape orientation with its screen facing the camera operator, and mount it so that it is perpendicular to the camera's optical axis. This allows the iPhone to capture the movement of the camera's optical axis.
MCO obtains the pan/tilt position of the main camera via Multi-Camera Control.
Connect cameras and the Control Panel application to MCO. Connection settings are performed in the Control Panel application.
■ Connection Settings for the Control Panel Application
Connect the Control Panel application to MCO.
1 Start MCO (P. 17).

■ Connecting an Overhead Camera
Connect overhead cameras to MCO. Select the [Connection Settings] tab from the screen switching tabs. [Overhead Camera Settings] will be displayed.
The setup procedure is the same as steps 2 to 6 in "Connecting a Main Camera/Sub-Camera" (P. 24).

Note
Since the overhead camera is a remote camera, [Device Type] is not selected. Also, because no role is assigned, [Camera ID] is not selected.
Before shooting with MCO, you need to configure the stage settings. The stage settings include configuring the stage area, setting up tracking exclusion areas, and measuring and registering the camera position.
Areas/Markers Used for Stage Settings

(1) Shooting range
The shooting range for MCO. The shooting range is defined as the area within which the entire bodies of all subjects, when moving within the stage area, are fully captured within the viewing angle of two overhead cameras.
(2) [Stage Area]
The area within the shooting range where the subject moves.
(3)-(7) Markers A/B/C/D/E
Markers required for measuring the camera position. Position the markers so they are centered in the viewing angle of all cameras (main camera, sub-camera, and overhead cameras).
(8) [Tracking Exclusion Area]
An area in which, during tracking shoots with MCO, tracking is paused, and while tracking is paused, no search or selection of a tracking target is performed.
■ [Stage Settings] Tab Screen

(1) [Apply]
Applies the stage settings from the Control Panel application to the MCO.
(2) [Get Latest Settings]
Updates the Control Panel application with the stage settings currently applied to the MCO.
(3) [Camera Position Measurement]
Displays the [Camera Position Measurement] screen.
(4) [Stage Area]
Configures the stage area.
(5) [Tracking Exclusion Area]
Configures the tracking exclusion area.
(6) Area/Camera/Marker display area
Displays the configured areas, cameras, and markers in an overhead view.
■ Stage Area Setup
Set up the stage area. Measure the actual width and depth of the stage area, as well as the relative distance from Marker A (reference marker), and input these values into the Control Panel application.
Open the [Stage Settings] screen from the screen switching tabs (P. 19) in the Control Panel application.
1 Measure the [Width (m)] and [Depth (m)] values of the stage area and enter them in [Stage Area].
- The recommended size for the stage area differs depending on the license type.
![]() |
^ Under certain camera installation conditions, performance may be reduced.
- By setting the stage area slightly larger than the actual range in which the subject can move, you can reduce the risk of the subject not being detected at the edges of the area.
2 Place Markers A / B / C / D / E.
The greater the distance between markers, the higher the accuracy of camera control. A distance of at least 2 m (6.6 ft.) is recommended.
- Position the 5 markers so they are centered* in the viewing angle of all cameras (main, sub and overhead cameras).
- Place markers A, B and C on the floor of the stage area.
- Markers A and B should be placed parallel to the horizontal direction of the stage area and at least 1 m (3.3 ft.) apart from each other. In this case, marker A is placed on the side of stage right, and marker B on the side of stage left.
- Marker C should be placed at least 1 m (3.3 ft.) away from A and B in the front-back direction.
- Place Markers D and E at a height of at least 1 m (3.3 ft.) above the floor of the stage area.
- Markers D and E should be placed at least 1 m (3.3 ft.) away from A and B in the front-back direction, and at least 1 m (3.3 ft.) apart from each other.
* When measuring the camera position, you must adjust so that each marker is at the center of the viewing angle at the camera's maximum zoom.
Note
• Each marker is used as a visual reference to ensure all cameras capture the same field of view during "Measure Camera Position" (P. 30).
- Place markers that are no larger than 1 cm (0.39 in.). If the markers are too large, measurement precision may decrease, affecting camera-control accuracy.
- Marker A serves as the reference marker and is used as the baseline for measuring distances during stage setup.
- If the camera positions are changed, you will need to use the markers again to perform camera position measurement and connection setup for Multi-Camera Control (P. 29). To make repositioning easier, it is recommended to mark the positions with tape or use fixed reference points such as walls.
3 Measure the relative position of the stage area from Marker A and enter it in [Stage Area].
- The relative position of the stage area is determined by measuring the distance between the vertex at the back side of stage right and Marker A.
- When viewing the stage area from the camera side, if the stage area is to the left of Marker A in the horizontal direction or above Marker A in the vertical direction, input the distance as a negative value.

- Enter the measured distances into the fields [Offset from A (Horizontal) (m)] and [Offset from A (Vertical) (m)].
4 Check that the 5 markers are centered in the viewing angle of all cameras (main, sub and overhead cameras). If a camera does not cover them, reposition the markers or the camera.
5 Click [Apply] to apply the settings to MCO.
■ Set the Tracking Exclusion Area
You can optionally set up tracking exclusion areas. This is useful in situations such as when there are posters with people in the camera's field of view. By setting exclusion areas, the system can more accurately detect the intended subject. Up to four exclusion areas can be set. The setup procedure is the same as for the stage area (P. 27).
1 Click one of the [Tracking Exclusion Area] areas.
The input fields for the selected area will be displayed.
2 Select [Rectangle].
3 Measure the [Width (m)] and [Depth (m)] values of the tracking exclusion area and enter them in [Tracking Exclusion Area].
4 Measure the relative position of the tracking exclusion area from Marker A and enter it [Tracking Exclusion Area].
- The method for measuring relative position is the same as in "Stage Area Setup" (P. 28).
- Enter the measured distances into the fields [Offset from A (Horizontal) (m)] and [Offset from A (Vertical) (m)].
5 Repeat steps 1 to 4 as necessary.
6 Click [Apply] to apply the settings to MCO
■ Multi-Camera Control Connection Setup
Perform the connection setup for Multi-Camera Control when the main camera is a digital cinema camera, a video camera, or a system camera.

Note
You must install the iPhone onto the main camera in advance. Complete the procedure described in "iPhone Mounting for the Main Camera" (P. 23) beforehand.
1 Configure the iPhone's Ethernet settings and connect it to the server running the Core application.
2 Start Multi-Camera Control on the iPhone.
3 Register the sub-cameras in Multi-Camera Control.
You can check the live feed from the sub-cameras on the iPhone. Up to 4 sub-cameras can be registered.
4 Select MCO mode in Multi-Camera Control.
5 Enter the IP address/FreeD port number of the server running the Core application.
6 With the main camera (with the mounted iPhone) facing the reference marker*, start sending data.
This will start pan/tilt information output from the iPhone to MCO.
* Refers to Marker A placed during "Stage Area Setup" (P. 27).
7 Use the Control Panel application to measure the camera position (P. 30).
8 With the main camera (with the mounted iPhone) facing directly forward in the shooting direction, tap the onscreen button to set the displayed values to zero.
The forward direction will serve as the reference for the values displayed in Multi-Camera Control.
You can use this to confirm the direction in which the camera moves.

Note
- If the position of the main camera or iPhone is changed, you will need to measure the camera position again. Please follow steps 4 through 8 again.
- If you switch to the home screen or another application while Multi-Camera Control is transmitting, or if you resume after stopping transmission, make sure the reference marker is facing the same way as in step 6 before resuming.
■ Measure Camera Position
To enable automatic camera control by MCO, measure the camera positions in advance. For all cameras (main camera, sub-camera, and overhead camera), register each of the five markers so that they are within the camera's viewing angle, and then perform the camera-position measurements.

Note
If the camera positions are changed after measurement, you must remeasure the camera positions. Otherwise, proper shooting may not be possible.
