This guide explains how to set up a multi-camera system using up to four cameras, and how to use them for multi-capture video analysis and live streaming, in NV Play Cricket for Windows.
As with single camera configuration, use the following steps to add more camera inputs:
- Go to Tools > Configuration. The Configuration dialogue opens.
-
Click the Video Capture tab.
-
Click the Add new Capture Device link in the Video Capture Devices section. The Capture Device Settings dialogue opens.
Configuring audio settings
To configure audio settings for your camera input:
- Go to Tools > Configuration. The Configuration dialogue opens.
- Click the Video Capture tab.
-
Click the Multi-Cam Audio Settings link in the Video Capture Devices section. This link is only shown if more than one video capture device has been added/configured. The Audio Settings for Multi-Cam Controller dialogue opens.
- Configure the required audio settings for the camera:
- Use Primary Input for all Audio: This option uses the first camera's audio across all inputs.
- Disable External Audio on Individual Inputs is enabled by default. If Use Primary Input for all Audio is ticked, this setting is overridden, and audio is enabled across all camera inputs.
- Click Save to save and close, and then OK again to close the Configuration dialogue.
Configuring video settings
To configure multi-camera video settings for your inputs:
- Go to Tools > Configuration. The Configuration dialogue opens.
- Click the Video Capture tab.
-
Click the Multi-Cam Video Settings link in the Video Capture Devices section. This link is only shown if more than one video capture device has been added/configured. The Multi-Cam Video Settings dialogue opens.
- Configure settings for each camera:
- Label: Assign a name to each camera for easy identification.
- Fixed Pitch End: Assign Pitch End cameras (specify if cameras are fixed and pointing down or up the pitch). Also used for automatic ball clip processing when using the Vision AI system.
- Capture: Enable continuous capture and ball clipping.
- Instant Replays: Enable to use this video capture device for live streaming instant replays.
- Automatically Switch Cameras at the End of Each Over: Enable automatic switching between end cameras at the end of each over (disabled by default).
- Save the Switched Continuous Capture File and Ball Clips: Saves the switched video feed and associated clips (enabled by default).
- Click OK to close to dialogue, and then OK again to close the Configuration dialogue.
The Video Display panel will update with all camera inputs and Input/Label buttons showing below the video preview window. These can then be used to control the 'switched' camera feed shown/streamed.
Viewing multi-camera feeds and inserting replays
To view all camera inputs simultaneously:
- Go to View > Video > Multi-Cam Video Display.
- The ‘switched’ camera feed is highlighted in yellow.
- Thumbnails of each camera can be used to control the switched feed.
Managing Capture and Replay Settings
- If a camera input does not have Capture enabled (the Capture box is not ticked on the Multi-Cam Video Settings dialogue), an Enable Capture button will appear at the bottom-right. Clicking this will reopen the Multi-Cam Video Settings dialogue.
- If a live stream is running but a camera input does not have Instant Replays enabled (the Instant Replays box is not ticked on the Multi-Cam Video Settings dialogue), an Enable Replays button will appear. Clicking this will reopen the Multi-Cam Video Settings dialogue.
Once Instant Replays are enabled, camera inputs will show a Last Ball button on the Multi-Cam Video Display panel with the following replay options:
- Last Ball
- Last Ball (Slow-Mo)
- Instant Replay
- Instant Replay (Slow-Mo)
The selected replay option will be injected into the live stream. If time permits between balls or overs, multiple Last Ball replays from different angles can be shown:
Recording continuous video
To begin recording continuous video:
- Click the Start Live Capture button on the Video Timeline panel (View > Video > Video Timeline).
- Auto capture or manual ball clipping will record up to four clips per ball (one per enabled camera input).
- Only the 'switched' ball clip is encoded and uploaded to minimise CPU load.
The 'switched' continuous video is displayed in the Video Timeline panel, with recorded ball clips appearing as usual. Additional continuous videos from other camera inputs can be selected via the camera input dropdown next to the Continuous Video dropdown.
Scrubbing and Synchronisation
- If a ball clip on the 'switched' continuous video is scrubbed during recording, corresponding ball clips on the other continuous videos will also be scrubbed to match.
- After recording, scrubbing any ball clip will synchronise the corresponding clips across all continuous videos.
In a multi-camera setup, the Video Player panel includes thumbnails of multi-angle clips at the top-right. Clicking a thumbnail allows playback of the corresponding angle:
Ball clips can still be accessed from the same tools and panels, e.g., Ball by Ball, Video Ball by Ball, Scorecard, Match Stats Wizard, etc. All other Video Player features also remain unchanged, e.g., Stop, Play/Pause, Frame Advance, Mute, Full Screen (with arrow key controls), Drawing Tools, Add to Package, Save Clip, and so on.
Monitoring hardware load
Using a multi-camera setup significantly increases hardware demands. Ensure that your system meets the minimum recommended specifications for Premium Video Capture, Premium Live Streaming, and Multi-Camera Inputs (as specified in System and Hardware Requirements).
While using multi-capture, monitor your system's performance metrics:
- Go to View > Video > Live Video Statistics
- Ensure performance indicators remain black (healthy) rather than red (unhealthy)
