What makes a good camera for livestreaming?

The demand for livestreaming continues to soar. It's now an essential part of the everyday content creation menu, from corporate, education and sporting events to places of worship, weddings and music concerts.

Canon has responded to the growth in livestreaming with a number of new solutions for every level of videographer, such as EOS Webcam Utility software, which makes it straightforward to use more than 40 compatible Canon EOS and PowerShot camera models as streaming cameras, and a range of PTZ (Pan, Tilt, Zoom) remote cameras with software and hardware controller options for managing a multi-camera setup efficiently. Other options include the Canon XF605, XA75/XA70 and XA65/XA60 camcorders, with their extensive connectivity options, through to Canon's Cinema EOS pro video cameras such as the compact EOS C80, EOS C70 and EOS C50.

So how do you choose the best camera for your needs? "There are five components a camera should have in order to deliver high-quality footage for your livestream: reliable and accurate autofocus, powerful zoom, professional audio, intuitive controls and flexible outputs," says Aron Randhawa, Canon Europe Product Specialist.

"Some elements of livestreaming are out of your control, including platform compression and the audience bandwidth. But if you start off with a setup that's built for the job, then it puts you in the strongest position for the best possible output."

With livestreaming, there's no room for focusing errors. You can't edit out a bad shot, and if you aren't running a multi-cam setup then you will be unable to cut to a different camera if there's a problem. This is why Canon's reliable Dual Pixel CMOS AF system is a real asset for live broadcasts.

Dual Pixel CMOS AF technology is used throughout the EOS range, from EOS R System mirrorless cameras through to PTZ remote cameras and Cinema EOS pro video cameras such as the EOS C80, EOS C70 and EOS C50. It's also employed in the Canon XA75 and XA70, adding additional livestreaming versatility to these professional 1.0-type 4K camcorders.

"The face tracking is a real benefit," explains Ram Sarup, Product Marketing Specialist at Canon Europe. "If you have one of these camcorders mounted on a tripod and you're doing a presentation – as a lecturer livestreaming to students, for example – then having the ability to maintain focus on your face as you move is fantastic."

If you're working in a small studio environment, or even livestreaming from home, then you're unlikely to need a far-reaching zoom lens. But if you're covering a larger venue, then a powerful zoom, like the Canon XF605's 15x optical zoom and 30x advanced zoom, can make all the difference.

"This is where the XA65/XA60 and CR-N300, which offer up to 20x zoom, truly shine," says Aron. Newer models in Canon's PTZ camera range offer even greater reach: the CR-N400 and CR-N350 deliver 20x optical zoom in 4K, and a huge 40x Advanced Zoom in Full HD, making them a great option for large auditoriums. "They provide extensive flexibility when framing the shot, and they can also perform subtle, motorised zooms while broadcasting live.

"If you're using one camera then you won't have the flexibility of cutting to a different angle, but you can slowly go into a close-up from a wide shot, for example, when filming a wedding."

Coupling a high-quality 4K lens with advanced 5-axis stabilisation ensures a steadier image, allowing you to take full advantage of the high magnification offered by camcorders such as the XA65/XA60 (20x zoom) and XA75/XA70 (15x zoom) when you're moving around.

What if you're not using a camcorder but instead livestreaming with a camera with interchangeable lenses, whether it's a Cinema EOS pro video camera such as the Canon EOS C70 or a hybrid mirrorless camera such as the EOS R6 Mark II? The Canon RF lens range includes many lenses suitable for livestreaming with such cameras – including the pioneering Canon RF 24-105mm F2.8L IS USM Z and Power Zoom Adapter PZ-E2/PZ-E2B.

"The full-frame RF 24-105mm F2.8L IS USM Z represents the next step in optical engineering," says Aron. "It combines outstanding image quality with a fast f/2.8 aperture that's available throughout the focal length range.

"In live event situations, you can't necessarily control where you are as an operator in relation to the talent, so having that extra reach while maintaining a constant iris when you zoom is incredibly beneficial."

It's the 20-pin connector that unlocks this lens's true potential as a broadcast-style lens, though. "Attaching the Power Zoom Adapter or a focus demand to the lens provides the operability that broadcasters are used to in a professional live environment," adds Aron. "Using a controller, such as the Canon RC-IP1000, it's possible to not only operate a compatible camera such as a Canon PTZ camera, the EOS C70 or EOS R5 C remotely, but control the zoom as well."

For streaming, audio clarity is just as important as the image quality. With two built-in XLR terminals, the Canon XF605 is compatible with an extensive range of microphones, whether they're self-powered or not, and offers four-channel audio. The Multi-Interface Accessory hot shoe can expand XLR functionality even further with an additional two inputs, with the monitoring of all four audio channels possible on the screen via a firmware update.

Canon's XA and XF Series camcorders, the CR-N700, CR-N500 and CR-N400 PTZ cameras, as well as all Cinema EOS cameras, include XLR terminals as standard. The Canon XA75/XA70 and XA65/XA60, for example, all come with a detachable top handle that has dual XLR inputs, enabling users to record professional quality audio. It's one of the key features that differentiates these video cameras from the mirrorless camera solutions. What's more, each audio input can be independently controlled, offering users greater flexibility.

"Recording the audio in-camera means that the sound is already synced with the image, so you can immediately just go live with it, whereas if you're capturing audio separately, you will need to sync the audio in post, resulting in a longer workflow," explains Aron.

Many Canon cameras have a range of assignable buttons to customise the user experience. The Canon XF605 professional camcorder also has separate control rings for iris, focus and zoom, which means that single-camera operators working on the fly can easily adjust the image very efficiently.

"We also have many other ways of controlling our cameras," says Aron. "There's our Browser Remote, for example, which enables you to preview the image from our professional camcorders and Cinema EOS cameras over a network, as well as adjust the autofocus and the exposure settings on the camera. This can be an efficient way of controlling our cameras from a distance."

EOS Utility software for Canon mirrorless cameras is similar to Browser Remote, and gives you control of exposure, focusing and other aspects of recording when the camera is connected to a computer over USB. "You can also instantly convert numerous EOS mirrorless cameras into high-quality webcams using EOS Webcam Utility software," adds Aron.

There are Canon control solutions that are especially beneficial to camera operators working in a professional livestreaming or live broadcast environment. The Canon Multi-Camera Control smartphone app for iOS provides an intuitive and convenient way to control up to four cameras from a smartphone, for example. It is compatible with selected Cinema EOS cameras, such as the EOS C70, EOS C80 and EOS C300 Mark III, plus several Canon PTZ camera models, as well as the XF605 following a firmware update.

The PC-based Canon Multi Camera Management Application offers more comprehensive coverage. It has the capability to monitor up to 200 cameras, including almost all Canon PTZ cameras, a number of Cinema EOS cameras and the XF605.

"These are two different control solutions for different types of users," explains Aron. "While the smartphone app is ideal for a relatively simple setup where a solo shooter needs to control a couple of cameras, the Canon Multi Camera Management Application is geared towards a larger production ecosystem, such as a studio with numerous unmanned cameras."

There are dedicated remote controls for Canon's video cameras too. "Canon Remote Controller RC-V100 gives professional camcorder users extensive options for fine-tuning the image," Aron explains. "This is especially ideal for livestreaming, where you cannot adjust the footage in post-production.

"Another really interesting option that we introduced with our PTZ remote cameras is XC Protocol. We've since added it to the Canon XF605 and our Cinema EOS range, including the EOS C300 Mark III and the EOS C500 Mark II, via a firmware update, which can be downloaded from Canon's support pages.

"XC Protocol enables the Canon XF605, PTZ cameras and Cinema EOS cameras to seamlessly integrate into a live production workflow. Using the Canon RC-IP100 or RC-IP1000 remote controllers, you can adjust the pan, tilt, zoom, focus and exposure settings on a PTZ camera, and you can now control the other cameras too."

The more advanced RC-IP1000 is essentially a hardware version of the software multi-camera control solutions, enabling up to 200 remote cameras to be monitored and adjusted via a large joystick, 7-inch colour touchscreen and 56 buttons and dials. "Having a hardware controller with multiple buttons that are tuned to the way that the operator likes to work will help things in a professional environment where speed is key," says Aron.

Canon offers camera solutions ideally suited for integration into livestreaming workflows with a variety of outputs, such as HDMI or more robust connections, such as SDI for linking to live production switchers.

"The 12G-SDI output of the Canon XF705 and XF605 camcorders has very low latency and provides a secure cable connection, for integration into a professional production environment," says Aron. The CR-N700 and CR-N400 PTZ cameras also feature 12G-SDI output, which supports high resolutions and frame rates, including 4K 4:2:2 10-bit signals up to 60p over a single cable. All of Canon's PTZ camera range except the base model CR-N100 offer 3G-SDI and HDMI.

In addition to their 3G-SDI and HDMI terminals, both the Canon XA65 and Canon XA75 are equipped with a USB-C output which supports Full HD UVC streaming in Windows or MacOS. The Canon XA60 and XA70 camcorders, as well as the CR-N400, CR-N350, CR-N300 and CR-N100 PTZ cameras, also come with the convenience of UVC compliant USB-C connections, ensuring that they're easy to set up and use with camera applications on your computer.

IP streaming capabilities also feature in many Canon cameras, including the PTZ camera range, XF605 camcorder, EOS C80, EOS C70 and EOS C300 Mark III. "Although these will need a decoder connected to the camera, it means the signal is already in the required format to be efficiently streamed over a network," says Aron.

"Some people may want to simply take the HDMI or SDI output and put that into a production switcher, which will then encode it and stream it live. An alternative that requires less hardware, however, is to have your cameras connected to a local area network and then go through an IP-based livestreaming software solution. It's another option to consider when you're choosing the right workflow for your needs."

Support for SRT (Secure Reliable Transport), a broadcast-standard protocol that enables high-quality streaming in unstable or unpredictable network conditions, comes as standard with the CR-N700, CR-N400 and CR-N350 PTZ cameras, and it's also available for the CR-N500 and CR-N300 via a firmware update. Adjustable bitrate support for SRT is available via additional firmware.

All Canon indoor PTZ cameras also offer RTMP/RTMPS (Real-Time Messaging Protocol and Real-Time Messaging Protocol Secure), which enables content to be shared directly to platforms such as YouTube and Facebook.

A Canon XF605 firmware update brings SRT protocol support to this popular professional video camera as well, giving ENG crews a reliable streaming option when they're in the field. The firmware also adds a chunk transfer function, which enables breaking news footage to start being uploaded to the newsroom while it's still being recorded.

"Bite-size video clips are recorded to the second card slot of the camera, which are then automatically transferred to a news server via FTP," explains Aron. "As a result, the newsroom will be getting the information much quicker and be able to process it while the video is still being recorded."



Livestreaming continues to be an essential part of the content creation mix and Canon is excited to be able to support this burgeoning area of production with tools that work effortlessly together, enabling users to focus on the content.
