Professional Live Streaming and Virtual Production

• UVC: USB Video Class functionality allows you to connect your camera to a computer via USB and it will appear as a webcam.

• HDMI Output: Use an HDMI cable to connect the camera to an external video capture device or encoder.

• SDI Output: For professional setups, use an SDI connection to a compatible capture card or switcher.

• Network Streaming: Some Canon camcorders and cameras offer built-in network streaming options that can connect directly to streaming platforms.

• Direct Streaming: Some Canon cameras, like the C400 and XF605, can stream directly over a network without additional hardware.

• Many Canon mirrorless and video cameras support USB Video class (UVC), which allows them to act as a USB webcam over a wired connection

• Resolution: Most Canon cameras support 1080p Full HD and 4K UHD video.

• Frame Rates: Common frame rates include 24p, 30p, and 60p for smooth video. Higher frame rates may be available depending on the model.

• Camera Control Software: Canon offers software like EOS Utility of the Multi-camera control application for remote camera control.

• PTZ Control: For PTZ cameras, use Canon’s remote-control options or third-party software to adjust camera angles and settings remotely.

• External Microphones: Canon cameras with XLR inputs or 3.5mm inputs allow you to connect high-quality external microphones.

• Built-in Mics: While built-in microphones are available, external mics are recommended for professional audio quality.

• Menu Settings: Access the camera’s menu and enable clean HDMI output, which removes on-screen displays and overlays.

• External Recorder: Connect the camera to an external recorder or streaming device to ensure a clean video feed.

Cameras: High-definition or 4K cameras with live streaming capabilities.

Microphones: High-quality audio capture is crucial, so consider lapel mics, shotgun mics, or headset mics. Some streaming configurations will require audio to be captured on the streaming computer instead of the camera.

Lighting: Proper lighting enhances video quality and visibility.

Encoder: Hardware or software encoders are used to convert video signals for streaming.

Streaming Platform: Choose a platform like YouTube Live, Zoom, or Facebook Live.

Network Connection: A stable and fast internet connection is essential.

Resolution: Opt for cameras with at least 1080p resolution; 4K is preferable for high-quality streams.

Connectivity: Ensure the camera has HDMI or SDI outputs for connection to streaming equipment.

Autofocus and Low-Light Performance: Features like Dual Pixel CMOS AF and good low-light capabilities are beneficial.

Hardware vs. Software Encoders: Hardware encoders are more reliable and suitable for high-demand environments, while software encoders are more flexible and cost-effective.

Popular Options: Hardware encoders include devices like the Teradek VidiU or Roland V-60HD, while software encoders might be OBS Studio or Wirecast.

Use Quality Microphones: Invest in high-quality microphones that suit your environment (e.g., lapel mics for speakers, shotgun mics for general capture).

Monitor Audio Levels: Use headphones to monitor audio in real time and adjust levels as needed.

Minimize Background Noise: Choose locations with minimal background noise or use soundproofing.

Resolution and Frame Rate: Set your camera to match the resolution and frame rate of your streaming platform (e.g., 1080p at 30 or 60 fps).

White Balance and Exposure: Manually adjust white balance and exposure settings to ensure consistent and accurate colour reproduction.

Focus: Use manual focus or set the camera to use continuous autofocus if it supports it.

Encoder Settings: Adjust your encoder settings to minimize latency, such as using lower buffer sizes and faster presets.

CDN: Choose a Content Delivery Network (CDN) that offers low latency options and is geographically close to your audience.

1080p HD: Typically requires a bit rate between 4,500 to 6,000 kbps.

720p HD: Generally, requires a bit rate between 2,500 to 4,000 kbps.

4K UHD: Needs a bit rate of 15,000 to 25,000 kbps or higher.

Virtual Production is a method of filming in a specialised studio where a wall made of LED screen (known as a volume) acts in a similar way to a chromakey background.

The benefits of filming with a volume rather than a blue or green screen include increased possibilities for camera movement and perspective changes as the camera communicates with the volume in sync.

The Canon EOS C400 is ready for Virtual Production out-of-the-box outputting real-time metadata required via the RF mount’s high-speed communication capabilities. Plug-ins are available for Unreal Engine and Adobe After Effects.

Audio Mixing: Use an audio mixer to balance sound levels and manage multiple audio sources.

Latency: Monitor audio sync with video to prevent delays. Adjust audio settings to match video delay if necessary.

Audio Sources: Ensure all microphones and audio sources are properly connected and tested before the event.
