Integrating CaptureCast and NDI®

With the addition of NDI® support to CaptureCast, and the upcoming release of the CaptureCast NDI® a lot of people are wondering how exactly NDI® can fit into their workflow, and how an IP workflow can work for them – so today we’re going to take a look at how you can take advantage of the flexibility that a Video over IP workflow allows while . CaptureCast allows you to create preset templates to record multiple incoming NDI® streams simultaneously, and save each of those recording sessions directly to MP4 files that can quickly and easily be tagged, sorted, searched, and viewed over a local network, or directly on the CaptureCast box itself. This flexibility allows you to tap into creative workflows with numerous publishing endpoints like YouTube, Kaltura, and Panopto for on demand media, all while simultaneously broadcasting to multiple live streaming providers.

The easiest way to envision this transition to networked video input is to think about network cables as direct replacements for traditional video connections like HDMI and SDI. Instead of directly routing the camera signal from the camera to the recording device, we are instead creating a broadcast for each device on the network. Many new cameras now have NDI® support directly built into their firmware, allowing you to simply plug one into power and network – with some cameras supporting Power Over Ethernet and only requiring a single cable for both power and networking.

But what about computers? Especially when it comes to recording video of a presentation, it’s important to be able to have a way to transmit the output of a computer over the network for ingestion in CaptureCast. NDI® makes it easy to bring together all the sources you need to make today’s modern hybrid world work, and this is where an extensive selection of different IO converters come into play. WIth a device like a NewTek Spark, BirdDog Mini, or Magewell Pro Convert, you can take the digital HDMI output signal from a computer, document camera, digital teaching devices, or legacy HDMI cameras, transmit it over the network, and also pass that signal through to the originally intended destination, whether that be a projector, TV, or monitor. 

Many NDI® users make use of a dedicated AV network separate from their organization’s main network. However, if this is not possible due to wiring constraints,oftentimes, separating AV traffic into its own VLAN can be just as effective, and much more cost efficient. However, if you can build a physically separate AV network, or already have one in place, this is where the multi-network capability of the CaptureCast Pro NDI® comes into play. Instead of having to pick and choose whether you want your CaptureCast recorder to be able to communicate over the AV network or your wider WAN-connected network, you can use both simultaneously, sending the relevant traffic to whichever network is required – making use of the dual 10Gigabit Ethernet ports to connect to an AV network at an even higher speed if your network is built to support it. If you’re building a new AV network from scratch, we highly recommend a good PoE switch, like Luxul, for the best experience, though if you’re in a pinch for money, Unifi devices can also provide an excellent middle ground between price and reliability. Both vendors offer plenty of Power over Ethernet devices, which are ideal for the reasons we outlined above.

Once you have your cameras, IO converters, and CaptureCast recorders all connected to the same AV network, you’re ready to go – CaptureCast will automatically be able to see the NDI® devices on the network, and you’ll be able to use them in simultaneous single and multi-source recording and publishing workflows. All NDI® inputs are hardware encoded, which means we can currently support up to 6 simultaneous NDI® sources with the CaptureCast Pro NDI® – but thanks to the power of network video, you can keep every one of your CaptureCast recorders safely stored away in far fewer places, either in a completely centralized server room, or in localized network closets for specific buildings, instead of needing to deploy one to every single room in your facility you need to record. By centralizing your recording devices, both monitoring and management of the physical hardware becomes significantly easier.Another exciting benefit is the ease with which you can expand your network of capture devices. All you need to do is install another recorder in the rack, and you’re able to record six more NDI® inputs, in any configuration you’d like.

We hope you’re just as excited about NDI® and the new opportunities it brings to the table as we are. If you’d like to learn more, reach out to us via our contact page or by sending an email to sales@catturavideo.com to schedule a demo and further discuss the possibilities that CaptureCast can create for your organization today! We are now taking preorders for the CaptureCast Pro NDI®, and will start shipping soon.
