NewTek now makes cameras: 3 important new announcements from the TriCaster maker

NewTek proves that good things come in threes, with the announcement of an IP-Native camera, new - and wireless - video to IP converters, and the release of version 3.0 of NDI.

NewTek’s NDI ecosystem is gathering power and momentum today with the announcement of three new elements to the openly-available video over IP technology. If you’re not familiar with NDI, here’s a quick primer. 

Traditionally, video has been sent from point to point using SDI. Most cameras either have SDI ports or HDMI. It’s easy to convert between HDMI and SDI without quality loss. 

To get digital video onto a network, it has to be encoded as an IP stream. Once this has been done, it can be routed just like any other type of digital data, with the notable exception that the “signal” will be continuous and contain a lot of data. 

Lots of companies are working on Video over IP. Some are working with uncompressed video, which demands very fast, mostly dedicated networks. 

NDI compresses the video but does so gently so that it remains broadcast quality. This NDI-specific compression is low-latency - there are no delays; and it’s accurate. Timing is precise and as deterministic using SDI but massively more flexible as there is no need for physical matrix routers. 

NDI is easy to use: just select sources and destinations from a menu. The system takes care of “discovery”: Just add a new source or destination and it appears to all the other connected devices. 

NewTek’s new generation of Tricaster - the Tricaster TC1 - uses NDI exclusively for input and output. It’s a complete live production system that relies on IP video. 

Who’s using it? A growing number of companies, including BirdDog, Bluefish444, Microsoft Skype, NewBlueFX, OBS, Panasonic, PTZOptics, SplitmediaLabs – XSplit, Broadcast Pix, Ross Video, Telestream, Wirecast and Gameshow, vMix  - and of course NewTek.

Today's specific announcements

First, NDI 3.0 is here, and as befits an integer release, it’s a big one - the biggest so far, in fact. There are overall efficiency improvements with faster encoding.  And there’s good news about compatibility: it’s compatible with past versions as well as future ones too, with minimal changes needed to applications to support it. 

Perhaps the biggest deal with NDI 3 is Multicast. 

This new mode, complete with forward error correction (FEC) is an extremely efficient way to use a network for multiple destinations that want to see the same source. Effectively (and this is a massive oversimplification) multiple destinations “pretend” to have the same IP address. This means they can all tap into the same stream, without needed a separate stream for each destination. 

NDI handles this simply and transparently and allows the system to fall back to conventional Unicast mode if necessary. 

Here are the other new features in NDI 3: 

High Efficiently Mode (NDI|HX) allows for full resolution, full frame rate with limited bandwidth wireless, remote and large scale networks. 
Pan / Tilt / Zoom camera support standardises video, audio, tally and camera control. 
Improved encoding performance Software encoding has always been impressive with NDI but these new figures are astonishing. On a modern Intel i& based system, you can expect 1080p at 2500 fps, 4K at 1000 fps, 8K at 320 fps

That Pan / Tilt / Zoom support is in there for a reason. 

NewTek PTZ NDI camera

The second announcement is that NewTek now has a PTZ camera that speaks NDI natively. The camera needs only one cable carrying the video signal, PTZ data and power. So it’s easy to install and set up. In fact, it’s completely “plug and play”.

The new device sends full 3G 1080p 60 directly to NDI-compatible products across and standard IT network. 
Once the camera is connected, it’s visible to all systems running the latest version of NDI, including LiveStream Studio, SplitmediaLabs XSplit, Streamstar®, OBS Studio, StudioCoast vMix, Telestream Wirecast, NewTek TriCaster®, and "hundreds more”.

The NewTek NDI PTZ camera can be ordered now and will begin shipping on August 1st 2017 at a US MSRP of $2,700. 

NewTek Connect Spark

Finally, to help to bring non-NDI devices into the IP video world, NewTek is releasing Connect Spark. This accepts SDI or HDMI connections and converts the signal to NDI - not just via a wired connection but via WiFi too. This opens up all sorts of possibilities for wired and wireless topologies and most importantly makes it easy to bring virtually any existing video device into the NDI ecosystem. 

NewTek Connect Spark devices can convert up to 3G SDI or HDMI 1080p with loop through. They will also allow recording in MP4 to an SD card or USB drive. Recording is controlled and configured through a web interface. 

Connect Spark devices will start shipping on August 1st starting at US$ 499 MSRP. 

Finally

NewTek’s decision to bypass the usual standardisation process and develop their own end-to-end system is paying off. We’re told that literally hundreds of third parties - including major names - are adopting NDI. At the very least this makes it a de-facto standard. Ultimately it might be the one system to dominate the industry. It’s already well on its way to do so. 

NDI may not have followed a standardisation procedure, but it is openly available to all, free, and comes with a detailed API. 

This means that NewTek can make the maximum use of available and future technology, without the inevitable delays that standardisation would incur. We think that this, together with their openness, has put them in a virtually unassailable position of ubiquity for production quality IP video.
