How to synchronize multiple cameras to a video switcher

We’ve heard our customers asking about multi-camera streaming when using webcams like the Logitech C920 and Logitech C922 . We’ve also heard setup isn’t always that intuitive – or that software updates are impacting multi-camera streaming settings.

We hear you! We want to make sure you have the tools you need to be successful. To get started, watch this step-by-step video to help you set up your cameras the way you want.

We also know you’ve got questions about drivers, software and more. Here are some of the most frequently asked questions and answers.

What is the effect of using standard UVC drivers on Logitech drivers?

Logitech drivers were developed before UVC drivers were optimized for webcams. Today, standard UVC drivers are great for controlling streaming settings from multiple cameras while maintaining a stable environment. The video quality remains unprofessional.

So why am I having professional problems with the C920 webcam and UVC drivers?

The Logitech C920 webcam works with Logitech Webcam Software (LWS), which is professionally designed to work with Logitech drivers. As a result, using the Logitech C920 with a standard UVC driver prevents the LWS from functioning properly. Alternatively, we recommend the following applications:

-Windows 8 and 10: Microsoft Camera application (installed by default)

-Windows 7: OBS or XSplit broadcaster

-Mac: Quicktime or OBS

Also, make sure your webcams are plugged directly into your computer’s USB port, as USB hubs can limit the available bandwidth.

Does this also apply to the Logitech C922 webcam and / or the Logitech BRIO 4K Pro webcam?

No. These webcams use standard UVC drivers.

I have stopped using LWS and now I want to use it again – can I go back?

This is. Pro Games Logitech Webcam Software 2.8 can be reinstalled from our website.

When is the next LWS update expected?

Since the UVC drivers are now optimized for webcams, it is no longer necessary to use LWS. As mentioned above, we recommend registering applications such as:

-Windows 8 and 10: Microsoft Camera application (installed by default)

-Windows 7: OBS or XSplit broadcaster

Dubai, United Arab Emirates, March 9, 2021 – FOR-A Middle-East Africa, a subsidiary of FOR-A Company Limited, today announced that Cubic Media Production, a broadcasting and vocational training company based in Abu Dhabi, Emirates United Arab, docked is the latest professional development vehicle with FOR-A HVS-490 digital video switch. The truck has been booked for a variety of high-professionalfile professionaljects, from multi-camera professionalduction of professionalfessional football matches to last month’s coverage of the historic UAE Mars professionalbe for Abu Dhabi TV.

Built last summer on the chassis of a Mercedes-Benz Sprinter van, UNIT2 4K is a compact yet powerful mobile unit that typically uses eight professional HD cameras or six professional 4K cameras. Feras Hamdan, Managing Partner and COO of Cubic Media Production, said the HVS-490 was perfect for the new truck as it contained features and options usually found in larger switches. UNIT2 4K also uses all three of the switcher’s multi viewer outputs.

In addition to the HVS-490, UNIT2 4K also includes two FA-505 and three FA-9600 multi-channel professional signaling accessories, mainly used to convert external sources to 4K during professional production. However, professional accessories can also be used to synchronize inputs, embed and remove audio, color correct and convert 4K to HD or HD to SD movies. Other FOR-A devices installed include the MFR-3000 and MFR-3232 routing switches.

This is not Cubic Production’s first FOR-A purchase; the company has FOR-A devices in many of its mobile vocational training units. “We trust their professionals in our live broadcasts and their support here in the UAE,” said Hamdan. “The exceptional technical and operational support we receive before and after the purchase gives us the confidence that we have FOR-A on most of our transmission networks. It gives us the feeling that FOR-A is a member of the team, not a professional vocabulary. “

“You don’t get selected to professionalduce live coverage of prime professionaljects like the Mars professionalbe unless your company is reliable and delivers high-quality work,” said Mohammed Abu Ziyadeh, FOR-A system engineering manager. “Cubic Production continues to place its trust in FOR-A professionals because they are reliable, affordable and feature rich in HD and 4K workflow.”

With integrated frame synchronizers and multiple browsers, the HVS-490 reduces the amount of hardware required for professional live instruction. Event memory and macro functions make it easy to quickly set up the switch for live performances, while support for multiple control panels allows multiple operators to work on separate tasks. MELite™ technology eliminates the need for multiple switchers in a multi-monitor staging scenario, and extends the switcher’s 2 M/Es to 6 M/E performance. When equipped with optional I / O expansion cards, the HVS-490 supports 40 in / 18 out, 36 in / 20 out or 32 in / 22 out, including dual channel HDMI outputs. Plus, FOR-A’s FLEXaKEY™ allows a traditional AUX bus to transform into a functional mix effects with cuts, mix, wipes, keys, and DVE including full preview.

Cut the cables and forget to connect all recording devices together. Professional recording with Panopto will change the way you record events.

How to synchronize multiple cameras to a video switcher

How professional recording works.

Capturing multiple camera angles in a single event or presentation usually required a lot of equipment. Literally. Several cameras would have had to be physically connected to a control station and countless complex switches, transcoders and other technologies would have been required to synchronize all these different streams.

Panopto’s professional recording eliminates everything. For professional recording (also known as multi-machine recording), connect each of your cameras and audio sources to an internet-connected computer and / or mobile device with Panopto installed. Instead of tying everything up with cables, each computer or mobile device can be configured independently. From there, after the pro, set up each computer to record the same Panopto session. Panopto will do the rest automatically, synchronizing each channel into a single non-professional professional training.

How to synchronize multiple cameras to a video switcher

Cut cables and reduce installation time.

Record quarterly events, monthly town hall meetings, or the company’s annual user conference with reduced setup time and at a fraction of the cost of hiring an external video production professional.

Professional recording means you no longer have to connect all devices and computers with hundreds of meters of cables in large rooms or auditoriums with complex AV setups. Record the presenter’s slides and audio from the front of the house, capture video of the presenter on stage from the back of the house, and let Panopto sync your feeds for you in the cloud.

“It’s amazing how simple it was — with Panopto, everything just worked. We immediately had repeatable and reliable professional success that we could use for [live broadcast] all future team meetings. “

Director of Information Technology, global manufacturer of sporting goods

How to synchronize multiple cameras to a video switcher

Record from different locations and networks.

Capture and mix video from global executives for your next face-to-face meeting or present a remote guest speaker without complicated setup or configuration. Panopto’s distributed recording capability enables you to capture and sync video from presenters in multiple locations. After the pro, use Panopto to record in both locations and save channels in the same session.

How to synchronize multiple cameras to a video switcher

Do it live.

Live broadcast from multiple camera angles thanks to professional Internet broadcasting.

Whether you’re streaming live or recording for on-demand viewing later, you can use Panopto’s distributed recording capability to sync multiple AV feeds from anywhere into one single broadcast. Live broadcasting is as professional as recording multiple channels in the same session and controlling live broadcast options in Panopto. All live broadcasts are automatically recorded and then uploaded to your video library, where any words spoken or shown in them can be searched and played on any device at any time.

This works for professional cuts. For transitions, you need to be aware of the effect on the length of the clip. Fades and fades do not lengthen or shorten the length of the clip, but any cross transitions (the ones with the two arrows facing each other in the transitions window) will compress the video. This is because both clips play simultaneously while the transition is in progress.

However, the solution is quite professional. Let’s say we want to perform a one second crossfade between two clips. After being pro, add a second of footage to the end of the first clip, the beginning of the second clip, or a little bit of both. In the example above, I often take only 4 seconds from the start of camera 2 instead of 5 seconds. So when I apply the cross dissolve it all comes together perfectly.

The reason I trimmed each camera clip is because it is easier for me to work with the start of each clip than to trim pieces from the center of the clips, especially since your clips won’t look pretty, even if they are 5 seconds long. Adding 3 seconds 12 frames plus 4 seconds 19 frames plus 2 seconds 11 frames (etc) gets boring and more error prone the longer you work on the profession.

When you’re done, trim the beginning of the film and audio to where you want to start (eliminating the slap scene). The easiest way to do this is to make a split and unwrap the opening clip. Add music video titles at the beginning and end and soon, You areprofessional!

Connecting multiple peripherals of the same type, such as two mice or two keyboards, is impractical in most cases, but Windows will still recognize all devices connected to the system, including the two webcams. This setup can be useful if you want to set up a basic home monitoring system. Windows 8 includes a native camera app that can detect both webcams and allows you to switch between camera views on the fly.

Please see this article

  • Connect both webcams to your computer
  • Click Start
  • Right-click anywhere on the screen

1 Connect both webcams to your computer

Can we control multiple DSC-QX100 cameras with Camera Remote API SDK from iPad OS7?

The goal is that multiple cameras “snap” the image at exactly the same time. Maybe each camera has an address (serial number). Can the software communicate with all cameras simultaneously using multiple addresses? The need is limited to photos and so-called fast, high-speed photography. Film is not necessary.

Unfortunately, you can only control one QX100 lens at a time. This is because the lens connects via Wi-Fi, and on the iPad you can only use one Wi-Fi connection at a time. This might be possible using a desktop computer with multiple wireless cards installed, but that would be the only way.

Come ha affermato un rappresentante Sony, questo non può essere fatto con tecniche "ufficialmente supportate".

The reason is that the camera acts as a Wi-Fi access point (AP), so while many devices can connect to it, most mobile devices can only connect to it and not anything else (since iOS and Android don’t they do support connections from multiple APs at the same time). Therefore, it is not possible to use other network interfaces when connected to the camera. (I don’t know much about iOS, but Android always prioritizes Wi-Fi over data from a cellular network, for example.)

Android devices have a feature called “WiFi Direct” that professionalvides more flexibility in terms of peer-to-peer interconnection, but iOS does not support WFD. ANSWERS WFD QX100 invitations and pairing request can be accepted (if I remember correctly) with a long press of the shutter button. However, the official app only supports normal Wi-Fi AP connections.

I have not yet tried to see if using Sony’s remote API along with the Wi-Fi Direct feature (unsupported but apparently present) works.
