There is no question that Newtek’s NDI is rocking the world of video production. Whether in corporate video, educational video, live streaming or low-end broadcast, it allows a transition to IP transport that’s profoundly attractive in many ways.
NDI delivers high quality video at very low latency, under one frame of video. A 1080p60 NDI stream requires at most around 150 mbps. This is ideal for production applications, which are quite separate from transmission/delivery, where lower bitrates are preferred and some seconds of delay is tolerable.
In the early days of NDI, if you needed to view an NDI signal on a monitor that required a Windows PC running NDI Studio Monitor. This is an application that can pick the stream off the network and display it on a monitor. It has some nice features, like the ability to overlay a second stream (picture-in-picture) and show audio metering.
I used this approach at Cluecon 2018, with a very small PC purchased just for the task (pictured above.)
As you may recall, I had something of an issue with my Pixel mobile phone back in September. The August update to Google’s Android Pie OS badly mismanaged the Wi-Fi radio, resulting in battery life measured in minutes vs hours. On a typical day, with limited use, the phone needed to visit the charger by 1pm simply because the Wi-Fi was enabled. This was entirely unacceptable for phone just 16 months old.
Like a good fan-boy, I reported the trouble to Google, who took as much information as I could give, without ever admitting to a problem. Their team of online volunteers handed out anecdotal info, essentially home remedies, without regard for reality. Some users simply thought that 12-18 months was about all you could expect from the battery, and it was time to replace the phone.
Google’s own support team (Tier 3 no less!) took over six weeks to advise that the battery was faulty and should be replaced. This did not jive with my experience, which was that the behavior started when an OS update was installed.
I explored the battery replacement with our local uBreakiFix store. I was referred to them by Google. That was an $80 remedy that could possibly mask the underlying issue. I decided not to bother.
Time passed. A few more OS updates arrived. Now, as my Pixel turns two year old, its battery life is back to normal. If it comes off the charger at around 7am, with Wi-Fi enabled, it lasts the full day with light use. It no longer gets warm in my pocket. It seems that Google eventually addressed the problem of managing the Wi-Fi radio. The problem that they never admitted existed.
Last week I had to spend some time at Gulf Coast Veterinary Specialists. I had only expected to be there a couple hours, but it turned into almost the entire day. As I was mostly killing time in the waiting area, I was using the Pixel heavily. By 2pm its battery was so depleted that I ran to a nearby shop to purchase a USB-C charging cable. That was to be expected, given the age of the phone and my preference for a bright screen.
In September, I was angry at Google. They were difficult to deal with and did not seem willing to take responsibility for their product. They were evasive, which I found deeply offensive.
It’s finally rolled around to time that I would normally be considering a new phone. I’m not angry anymore, but I do still feel like I was burned by Google. Not enough to jump to Apple. Maybe enough to consider Samsung. I haven’t carried a Samsung phone since the Galaxy Nexus back in 2012.
Google needs to get it’s head in the game. If you make the product, you need to take ownership of the issues. Openly and honestly. Their present support effort is seriously lacking.
My how time flies. It hard to believe that I’ve had Logitech’s Brio 4k Webcam Pro in my office for well over a year. While I reported some cursory observations here and here, I’ve yet to give it a proper review…until now.
As you may recall, I was quite eager to get my hands on a next-generation webcam. I had high hopes for what might be possible using a faster USB 3 connection to the host and a more modern sensor. Brio certainly addresses those areas and more.
My initial evaluation of Brio stalled for quite some time. At that time neither my desktop nor laptop, both a circa 2013, were up to the task of handling 4k video in real-time. While I was using Brio every week, I wasn’t properly able to exercise the little beast.
Happily, the eventual purchase of the Airtop-PC has provided a more than capable host platform. The Airtop has the CPU, GPU and connectivity necessary to cope with 4K video without breaking a sweat. Or making a peep.
I don’t normally parrot press releases, but I have the highest regard for VB Audio, the Voicemeeter Series and his Virtual Audio Cables. These are profoundly useful pieces of software.
I’ve used Voicemeeter from VB Audio since it launched. It’s great, simple audio mixing software for Windows. In truth, I now routinely use Voicemeeter Banana, which the more capable version, supporting extra virtual inputs and outputs. This is how I bidirectionally connect ZipDX to a Hangout and my headset for VUC each week.
Today VB Audio extends the Voicemeeter series further with the first official release of Voicemeeter 8, which Vincent has nicknamed Potato. Here’s the formal announcement:
Voicemeeter Potato Press Release VB-AUDIO SOFTWARE THURSDAY, JANUARY 17, 2019
Voicemeeter 8 (a.k.a. POTATO) is finalizing the Voicemeeter Series with an ultimate virtual mixing console application, offering 5 Physical I/O and 3 Virtual I/O to connect again more audio devices and more applications together and to provide more control on any kind of audio workflows (now from 44.1 kHz to 192 kHz).
This Voicemeeter release (version 18.104.22.168 / 22.214.171.124 / 126.96.36.199) offers new virtual audio drivers for the entire series (also to Voicemeeter Standard and Voicemeeter Banana) made to be more reliable, with optimal CPU load, better audio quality and fully compatible with all Windows versions (XP, VISTA, WIN7, 8, 8.1, WIN10 32 or 64 bits and Windows Server 2003, 2008, 2012, 2016 32 or 64 bits). Voicemeeter also installs virtual ASIO drivers (4 clients per ASIO driver) to connect 32 and 64 bits DAW’s and a Virtual ASIO insert driver made to connect a VST HOST to process any pre-fader inputs with any VST Plug-ins.
Voicemeeter Potato brings again new features inspired by audio pro mixing console and provides a better Microsoft windows integration. With the 8 BUS multi layer mixer, it is now possible to define an independent mix for each BUS (SEL Button). The internal FX section offers a reverb and a Multitap delay FX to invite musician or small bands to use it as music production mixer. The external FX section provides regular AUX with SEND and RETURN path to connect external hardware FX. Finally the Potato virtual input strips are showing the connected applications with a volume and mute control for each (as it is proposed by the Windows Volume Mixer).
Voicemeeter Series is also providing extra services through VBAN protocol to transport Real Time audio, Real time MIDI and Real Time Remote Control over network. Voicemeeter package also installs additional applications like MacroButtons, VBAN2MIDI and 2 examples of a BUS A.P.A. (Audio Processing as Application) a 15 Bands Graphic EQ and a 8×8 Gain Matrix. Finally with Voicemeeter comes a complete API to control any parameters or to process audio stream inside Voicemeeter in a client application programmed in any language supporting standard DLL. SDK Download and Voicemeeter Remote API information are on our forums.
Fair trade, affordable for everyone!

The entire guide to this new marketecture, which includes a library of symbols for use on packaging, is here. It’s worth a glance. Remember, the point of the exercise is to bring clarity to the oh-so-confusing world of Wi-Fi.
They’re taking pre-orders for the device, which marries a 4K PTZ camera with a 20x zoom lens, with the ability to drive dual, 4K displays. Thus it delivers 4K participant video and 4K full-motion shared content at each location.
Lifesize must be quite excited since the announcement happened even before they had marketing support for the device. Lacking for a spec sheet, I posed a couple of questions to their sales team. They report the device as leveraging H.264 baseline or high profile, with H.265 on the road map. Further, that 4k30 video requires 3 Mbps for each stream.
Dedicated RJ for the Lifesize phone provides power to the phone via POE.
Audio codec support includes; Opus, G.722.1, G.722, G.711 and Siren 7.
I’m a big fan of dog-fooding. That’s actually using the tech that’s being pitched. So I was happy to see that the promo video used in the launch of the Icon 700 are actually produced in 4K.
Lifesize began as a manufacturer of end-points and MCUs. They were founded by Craig Malloy, General Manager of Polycom’s Video Communication Division, who was frustrated at how slowly Polycom was moving into HD video conferencing.
In 2015 they made a major pivot from being a maker of traditional, installed MCU hardware to offering their MCU back-end as a cloud service.
This is NOT the first that I’ve heard of 4K video conferencing, but it is the first time I’ve seen a 4K-capable end-point appliance with a real PTZ camera. The Icon 700 lists for $7,500 USD.
