2022 Northwest Managers of Educational Technology Conference Summary

This April I attended the Northwest Managers of Educational Technology conference held this year in Coeur d’Alene, Idaho. Since there’s nothing quite like this group in the Southeast, it felt well worth it to me to fly across the country to enjoy a little normalcy and connect in person again with fellow A/V professionals focused on education. Of course, I can’t deny that the location for this year’s event on the shores of beautiful Lake Coeur d’Alene was an added draw. The conference was well attended (I’m guessing ~100 attendees), and exceptionally well run. NMET is a close organization with a history that spans several decades going all the way back to the beginning of the AV industry as we know it in the era of analog media.

Lake Coeur d'Alene


  • Responses to the pandemic and various school’s efforts to work toward a “new normal” 
  • The CARES Act as a catalyst for A/V classroom upgrades: UNLV launched a huge new program during COVID called RebelFlex using CARES funds that is seen as largely successful that would likely not have been possible otherwise. (Duke, along with several other top private universities such as Harvard and Princeton chose not accept CARES act funding.)
  • COVID as a driver for A/V initiatives and standardization: Many schools saw decision-making for A/V and IT-related projects shift to the provost level and higher as schools developed alternative teaching strategies such “emergency”, “HyFlex,” “hybrid,” “co-mingled,” and remote teaching as pandemic responses. In most cases timelines for implementing major A/V projects sped up significantly as well.
  • COVID as a driver for A/V standardization: Oregon State University described how COVID helped their campus standardize on an enterprise A/V strategy that centered on Kaltura, Canvas, and Zoom, and quieted demand for competing tools. Interestingly, OSU does not use a dedicated recording tool such as Panopto but instead utilizes Zoom for all recording and pushes this content to Kaltura within Canvas course sites. 
  • Faculty support models for hybrid teaching: UNLV’s RebelFlex program experimented with hiring students who were assigned to in-person classes as tech support. While overall this seemed successful, there were challenges, such as the diminishment of the need for tech support as the semester went on and faculty became familiar with the new technologies involved. Additionally it was observed that faculty members tended to morph the roles of their student help into roles resembling TAs and research assistants over time, including using these helpers as moderators for their Zoom chats.
  • Building a Networking Group like NMET: Some of the conference attendees were surprised I came all the way from North Carolina to attend the conference. “You mean the Duke?” several asked. I explained there’s nothing in the southeast comparable to NMET, an education-driven organization focused on the intersection of A/V and IT. That’s sad, but not surprising in a way, since a successful organization like NMET isn’t built overnight. NMET began holding conferences in 1979 and is the result of the hard work and passion of several generations of A/V professionals who have comprised NMET.
  • The A/V Superfriends Podcast (https://www.avsuperfriends.com/): Some of the members of NMET together with other A/V professionals extending beyond that group maintain a very cool podcast for A/V professionals focused on the intersection of A/V and pedagogy in higher ed. They were actually recording new episodes of the podcast live in the exhibit area. Members of this group led several interesting conference sessions focused primarily on the impact of COVID for classroom technology. Recent topics of their podcast include: 
    • Managing PO’s and supply chain issues
    • Campus support structures
    • Auto-framing and auto-tracking cameras
    • Cabling infrastructure and TIA standards
    • The intersection of A/V and IT in hiring new staff
    • AV replacement cycles–do we set arbitrary schedules of 5, 7, 10 years or tie AV refresh projects to capital projects?
    • Bootstrapping light video production switchers into classroom systems
  • AV over IP: It was argued by some that the NDI (Network Device Interface) protocol represents the wave of the future, and that we should future-proof our classrooms by purchasing NDI-capable cameras
  • Benefits and drawbacks of Zoom certification: It was discussed this may be OK as long as not mandated or exploited for commercial benefit (cross reference Tandberg)
  • “Hybrid” (instructor-driven) vs. “HyFlex” (student-centered) classrooms
  • USB as the “common language of hybrid learning spaces”
  • Elevating sound quality in the rush to add A/V infrastructure to classrooms 
  • Keeping classroom AV UI’s simple and standard even in classrooms where there is great complexity under the hood
  • ePTZ (auto-tracking) cameras: Importance of good lighting, fixed positions are better than continuous tracking
  • Making a virtual lightboard: One presenter showed how he used Procreate and a green screen in front of presenter to make a virtual lightboard 


  • Kaltura: Kaltura was one of three main sponsors of the conference. As mentioned above, Oregon State University, which was the main organizer of the conference, is a Kaltura customer. It was noted that Kaltura, unlike most other vendors, still offers an unlimited storage and bandwidth licensing tier, although it was mentioned it is “expensive.”
  • Panasonic: Panasonic was another major sponsor of the conference. Their projectors and displays were used in conference venues.
  • Elmo was showcasing its wide array of document cameras from a $200.00 USB to similarly portable wireless options starting at ~$800.00 to its flagship 4K, 12x optical zoom version designed for fixed classroom installations, the PX-30E (MSRP $3700.00). Interestingly, while WolfVision is the 500lb gorilla in the doc cam space, Elmo actually invented the document camera, and is the older company.
  • Epiphan was showcasing its well-known Pearl live encoder lineup along with its cool new device, the LiveScrypt. The LiveScrypt connects to Epiphan Cloud to add live ASR-based captions to your live production. These captions can be embedded with your live streams or sent out to monitors in the room for display for in person or hybrid events. There is a charge of $10.00/ hr to use the cloud-based ASR service in addition to the $1,500.00 cost of the device itself.
  • Alfatron had its wide range of PTZ cameras on display, ranging from a MSRP of $700.00 to $2150.00.
  • Shure had a booth showcasing equipment by Stem, a company they recently acquired. Stem offers complete solutions for outfitting conference and meeting rooms with a range of mics, including tabletop, wall, and ceiling mounted ones, together with a hub and an integrated control system for managing the individual elements.
  • Smart was demoing its latest lineup of interactive displays
  • Legrand AV showcased a wide range of products focused on physical classroom infrastructure, including displays, display mounts, projectors, PTZ cameras, speakers, device controllers, and network switches. Legrand is a large company that owns Vaddio, Chief, Da-Lite, and Middle Atlantic Products.
  • Cleardigital featured its modular display wall called Vue featuring very smooth touch surfaces and replaceable panels as well as other products such as a PTZ cam, the RL400, a portable doc cam and an all-in-one conference camera.
  • Newline Interactive was featuring its newest interactive and non-interactive displays ranging from 27” to 98”
  • AVer gave a conference session demo-ing its new autotracking PTZ camera, the TR333V2. The TR333V2 offers:
    • 30x optical zoom
    • Sophisticated pre-set configuration, including the ability to move in and out of continuous tracking and fixed position mode based on how an instructor moves in the classroom
    • 4k
    • 3G-SDI, HDMI, IP, and USB output 
    • Full or half body tracking

Dynamic Video Group Overview – Production Studio in Durham

I had the pleasure of checking out a local production studio called Dynamic Video Group. For the Academic Media Production Team, this will be a great resource to point folks towards who don’t fall under our typical purview or availability.

Their “studio | space” model allows clients to book by the hour. Selecting from a variety of backgrounds (green screen, white, brick, etc), the client can show up with a script and/or slides in hand and work with a studio manager to record on one or more 4K cameras. The studio is equipped with a teleprompter, screen capture options, and soon a lightboard. They can also facilitate live-streaming for recording high quality remote interviews over Zoom etc. The studio can bring on freelance editors if needed, but most of their clients prefer to get the raw recorded files and handle on their end. Similarly, they’re in touch with graphic designers,  and make-up folks should the need arise. Overall, seemed pretty flexible and adaptable to whatever you could throw at them.

With the pandemic, they’re shifting a lot of focus to virtual events, which is reflected in their virtual event studio model. Essentially, it’s an upscale zoom room where they can bring up the grid of participants, display the chat, spotlight guests on a dedicated monitor, etc. This all runs into a control room on site where they can moderate the stream, live switch between cameras, and provide technical support. Their new HybridLink model will even allow them to bring up to 4 cameras on location and send the signal back to their studio control room, bypassing the need for a mobile control room setup.

If you have any questions or plan to work with Dynamic, please get in touch with us at oit-mt-info@duke.edu.

Callouts 3 for Final Cut Pro

FXFactory recently released the third iteration of their Callouts graphics as professionally demoed here:



And as personally demoed here (cheesy bgs are built-in to FCP):

Of the various features, it’s probably about 50/50 stuff we in the Media Production team might actually use. The most valuable elements I found are the Compound Callouts which use arrows, boxes, and text to diagram information. They have a clean animation style and would work well for an instructor who didn’t have Keynote slides. It has a bunch of built-in shapes, similar to Camtasia, that can be helpful in creating quick pop-up graphics and annotations.

There’s also a couple of magnify filters which would work well with displaying a high-res photo or graphic and wanted to focus in on a small section.

One proposed use case was working with the lightboard. In one video, the instructor drew on the glass but her pen did not leave a mark. Our producer Brandon did an incredible job of making it look like she really drew what he added in post (jump to 13:40):

I didn’t even realize that clip had been animated. These callouts are better suited for something that’s not as subtle. Something similar could be achieved with a little creative editing, but there’s not much control for timing the animation or shaping the line to match something that specific. You could theoretically modify them in Motion, but that seems contradictory to using them for their convenience. Maybe they’re still worth getting as animations to build upon. 

All in all, there’s a ton of options for customizing style and you can keyframe just about any attribute you can imagine. Personally, it seems a little light for $60 but I think one could make good use of them in the right contexts.

The LightBoard Is Done!

After few weeks of rapid prototyping we’ve finished Duke’s version of the LightBoard pioneered by Michael Peshkin.


This great project will give a low tech method for people with traditional whiteboard learning modules to present them in a more camera friendly way for lecture capture or production.  The concept is simple, a large piece of glass is placed between the presenter and the camera who writes on it with a day-glow marker.  The video is mirrored so the text appears correctly to the viewer.  The result is a presentation where the lecturer can visually explain the lesson without turning their back to the learners or blocking the writing with their body.

That’s the simple concept.  In actuality the engineering was more difficult and we had several project goals and improvements we wanted to make over the original Peshkin model:

  • The project needed to be portable and lightweight but still not vibrate or move
  • Our version should simplify the lighting challenges as much as possible
  • The unit should be quickly deploy-able since it will be setup before and after shoots
  • The design of the system should not include any more custom fabricated parts than necessary and should consist primarily of commodity components easily sourced online
  • Final design should be documented and easily constructed by a junior technician or a non-professional fabricator.  It should not include any skilled labor for the build such as complicated electrical work, welding or metal cutting.

We made several simple improvements to accomplish our goals.  The structure was built entirely of 80/20 extruded aluminum making it light weight and simple to build while being easily sourced through online retailers.  We opted for an electronic solution to mirroring the camera versus using physical mirrors.  The system uses high quality casters making it easy to move.  The height of the design was also a factor as it needed to fit through a standard commercial door.  We avoided the temptation to at every turn to involve more complicated components and processes for the sake of simplicity.

2014-05-27 17.09.54

Regarding our lighting and deploy-ability.  We are operating on the assumption that most universities have access to a 3D Printer at this point.  Components that utilized custom designs have been published in formats that are easily 3D printable.  The designs of those components are also easily fabricated with simple carpentry in any campus wood or scene shop.

The one stand out of the design is the LED mounting system.  We found that no such product existed on the market so we designed our own and consider it to be the center piece of this version.  We found that holding the LED’s directly to the glass was the key to using low cost LED strips and less power.  The further the light source is form the glass, the less illumination there is by orders of magnitude.  There is also light leakage.  The system we designed holds the LED strips precisely and directly to the glass leaving little light leakage and greatly improving the efficiency of the light transmission.  We also discovered that a key to the design was to have the space on the lecturer half of the board well lit while the camera side of the board remains as dark as possible.  Applying large studio lights to that goal makes traditional 3-point lighting difficult since the lecturer will be just two or three feet from the glass.  To overcome that problem we added additional tracks for more LED’s that can discretely but effectively and evenly illuminate the subject.  This also allows light tuning, the strips on the subject side can be tuned to 2700-3000K for skin tones while light penetrating the glass can be tuned to 6000K to better illuminate the markers.  The result of the LED Clip greatly reduces the need for additional studio fixtures.

The Dawn of a new day


One of the challenges we’ve faced with the dLightboard is cleaning the neon Expo marker from the glass. Regular cleaners including Windex leave a haze as you can see above. We tried using Expo marker cleaner, but the smell was so incredibly bad, we’ve banned it from our lab and the first floor completely.


Chip tried using a squeegee with water. That worked well, but created a mess and would preclude us from putting LEDs on the bottom. So we lined up a bunch of products to test looking for a de-greaser.


No, we didn’t try CoffeeMate.

The winner was… Dawn! Mixing Dawn in a spray bottle with water (about 1/3 Dawn + 2/3 Water) did really well. We’d spray it on a paper towel and then use a dry paper towel to dry it up. As you can see below, no more haze!


dLightboard Development


Based on some AMAZING work being done at Northwestern University, Chip Bobbert from Duke’s ITS group partnered with the Duke Digital Initiative to build our own. We decided to first build a desktop prototype to work out construction challenges. That has proven to be a great approach as there were many.

Rather than welding parts, Chip used his experience with pre-fabricated aluminum parts from 80/20 to construct the frame for the piece. Billed as the “Industrial Erector Set” – the parts from this company really helped make this project achievable. Once the glass arrived, Chip realized that glass offsets that were commercially available would not do the trick. Since Chip also heads up DDI/ITS’ 3D printing project, he used that technology to create the offsets.

When it came time to mount the LED’s, Chip added a new feature of “self lighting”. A second set of LED’s were added to the original design which lit the glass edges to allow the neon Expo markers to illuminate. This second set was a warmer color temperature and was used to light the subject, eliminating the need for external lighting.  Dimmers were added to control both the edge light illumination and subject illumination.

In the example below, we tested using a $0.99 app called “LightDV” to flip the video in real time. For the desktop version, it’s thought that the subject could use their iPhone or iPad on a tripod stand to shoot the video, flipping in real time. Other tools such as Screenflow can also flip the video in post production.

The large version is still under construction. Challenges with the larger design and ordering parts will make this deliverable later this summer. Duke Media Services will take delivery of this and experiment ways in which they can provide this as a service to interested faculty and students.


Once the project is completed, Chip will provide a complete set of parts and details on construction if other schools or departments want to create a light board on their own.
