AI Tools

In the world of audio and video production, having the right tools can make a huge difference in the quality and efficiency of your work. In this article, we will be discussing three powerful applications that can help you take your audio and video production to the next level: Fliki, Dall-E2, and Descript AI. Each of these tools offers unique features and capabilities that can be used to create high-quality content quickly and easily.

Stephen Toback, does caution the use of the tools in a responsible and safe way before unleashing the magic of what these tools will do, and not putting Duke at risk. He highlights that the tools require users to give some information to it, and it’s important not to put any data into any of these applications that Duke hasn’t approved as public data. He also advises users to create accounts on the sites with alternate IDs, not Duke email address, and not to use the same net ID password. Additionally, he mentions that these tools are changing rapidly and should not be built into critical business applications yet. He encourages users to join an ongoing conversation about the tools in a Microsoft teams chat (Staff AI).

David Stein presented several AI tools such as Fliki a text-to-audio application that allows users to create high-quality audio recordings with a wide range of voices and emotions. Dall-E2 is a powerful application that has a wide range of potential uses, including the ability to generate detailed prompts for video and audio production. Descript AI is a web-based, collaborative system for video and audio editing that includes built-in capture from Zoom, green screen function, and stock images, music, video and sound effects. Together, these tools make it possible to generate high-quality content quickly and efficiently, with the added bonus of using ChatGPT for script and dialogue generation.

Another Script-Based A/V Editing Option: The Camtasia-Audiate Integration

Descript, a new video and audio creation and editing tool, has been making waves recently on campus with its ability to generate a script file for your project, and allowing you to edit the video simply by making changes to the script. One of the more useful things you can do with this approach is to automate the elimination of awkward “um’s” and pauses, adjust the speed and pacing of your project, and tighten things up quickly in other ways to make your media more listenable.

Some of you might not know, however, that there is a similar approach for those who already use Camtasia. Like Descript, Techsmith’s Audiate utilizes cloud-based speech-to-text technology to generate a script for your audio project. And like Descript, the changes you can make in Audiate, which include many of the things you can do in Descript, get exported back to your audio file without your having to touch that file in a timeline based editor. While Audiate in itself is geared for podcasters, those who are working with video or screen animation can get the full package via Techsmith’s roundtrip integration between Camtasia and Audiate. One cool feature of this integration we wanted to point out is that if you are working with a screen animation where you are using a cursor, Camtasia/ Audiate animates the movement of the cursor between cut points so your viewers don’t see it randomly jumping around on the screen. See below for a demo of Camtasia/ Audiate in action.

Pricing for Audiate at first glance seems to be about the same for Descript, so if you are working with video and are not already a Camtasia user, it probably makes the most sense to use Descript. However, there are discounts available for the Camtasia/ Audiate package.

Since interest seems to be growing in these types of tools and workflows, we would love to hear from you if you’ve tried either of them, and would especially be interested to hear how you think Camtasia/ Audiate stacks up to Descript for your use cases.

The Audio Engineering Society Convention

AES New York 2022

What is three days in a crowded convention hall full of audio engineers like?

It’s a completely immersive experience!

Mic Placement

Abbey Road Studio 2

 

The theme of this years edition of the AES convention was clear. Immersive and spatial audio is going to be the wave that propels the future of audio industry.  The range classes covered the entire work flow of how to plan, set up, record, mix, binauralize and distribute audio for the masses. Middleware like Wwise, Dolby Atmos and game engines like Unity and Unreal Engine will give audio engineers the tools they need to transition their audio tracks from stereo to an immersive aural experience.

 

 

Some of the highlights of the show floor that will be of interest include a sit-stand ready made podcast table and Ultra Low Profile Adjustable Mic Boom from Forecast and  O.C.White Co.

Magewell Capture & Combine USB Fusion is a multi-input USB video capture devise with integrated sourse switching and layout control. Offering two HDMI inputs and one USB webcam input, USB fusion can switch between sources or combine two inputs simultaneously into one output (picture-in-picture or side-by-side) for capturing into popular software via its USB 3.0 interface.

The Klover Mik 09 parabolic microphone is by far one of my favorites of the show! Engineered for the modern videographer, the KLOVER MiK 09 parabolic microphone is known as our “shotgun killer.” Attach it to the camera’s shoe mount, mount it to a light pole, attach a pistol grip, or even hang it from the ceiling, for long-range audio that’s always ready. By far the most comprehensive and effective demonstration I have ever been apart of!

This mic rig deserves an award all by it self!

Over the years I found that going to gathering like this often reward us with information that you never knew you needed or simply not aware of. Conversations with peers lead to things you simply cannot live without.

Like Krisp’s AI-powered, bi-directional Noise Cancellation eliminates background noise from your microphone and your speaker.

krispWith Krisp toggled “on,” you can rest easy knowing that your voice—and your voice only—is heard clearly. But Krisp doesn’t stop there. Sounds on the other end of the line are identified and eliminated, so there are no distractions to break your focus during that important meeting.

Shure/STEM ECOSYSTEM

The DDMC welcomed Ryan Budvitis & Brooks Platts from Shure’s conferencing and meeting product line up today. The STEM ECOSYSTEM audio products fill that gap just below professional audio products like the Microflex and the home office product lines at Shure. When you have a meeting space that can host 5-15 people and you would like to keep the AV simple and user friendly. The Shure STEM audio products is the right fit. The Audio Fencing feature reduces the busy streets and noisy offices that often encroach into most of our web conferences.

Additional features that include room design, one button room adapt, room check, and remote management are more features that helps the STEM ECOSYSTEM stand out in a very crowded USB peripheral market.

The DDMC met with our good friends at Panasonic this afternoon. All of us know they provide high quality classroom projectors. We just now discovered is they have a “pimp my projector” option with custom vinyl wraps! Custom Graphic/Logo/Colors. A 5-10 day Business day turnaround will get you stylin n’ profilin before the fall semester!

Also new to the Panasonic line of education products is their entry into wireless microphones with (11) new products that aim to be intuitive to use, lightweight and secure. Designed for lecture halls, auditoriums, the system has the flexibility to deliver excellent quality in spaces small too large.

New and notable is the Panasonic Lecture Capture & Auto – Tracking system. An all-in-one system to automatically track, record and stream video. Delivering a high quality, rich multi-source viewing experience. Co-developed & certified with Seneca and Panaopto for plug and play capabilities that should make for easy integration into existing AV systems. I have requested a (4) camera on site demo! So, stay tuned for further developments.

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

TOPICS

  • 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 


VENDORS

  • 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

Sennheiser

The DDMC hosted Sennheiser’s Steve Wingo who spoke about two very interesting technologies that might serve our community.

Team Connect 2

The TeamConnect Ceiling 2, with its patented automatic dynamic beamforming technology, was already a leader in conference room audio technology. Now, with the addition of TruVoicelift and advanced zone control, TeamConnect Ceiling 2 combines the advantages of a boundary microphone and a microphone array. Therefore, it is the best solution for both (video) conferencing and in-room audio, for example in classrooms, lecture halls and boardrooms. TeamConnect Ceiling 2 now offers our customers unparalleled levels of control with the addition of a priority zone (allowing a single area in the room to be highlighted), 5 advanced exclusion zones (for pinpoint targeting and removal of unwanted noise sources) and more. All of these new features are activatable and configurable via the latest firmware update for the TeamConnect Ceiling 2 and via the latest version of Sennheiser Control Cockpit. Easy to install and, due to a flexible microphone ceiling mount system, easy to integrate. Let us help you understand the difference TeamConnect Ceiling 2 can make for you and your business.

MobileConnect

MobileConnect consists of three main components: The MobileConnect Station is the “audio-to-network bridge” that picks up the audio signal in the room and streams it to any preferred streaming network. Using the pre-existing WiFi access points, the signal is provided to up to 100 smartphones per Station, using the MobileConnect App as a receiver. When using multiple Stations, the MobileConnect Manager can be used as the single point of administration for all MobileConnect Stations. If not needed, MobileConnect can also be operated in the so-called Standalone Mode, where single MobileConnect Stations can be run and administered using a local web interface.

mmhmm, Taking Advanced Online Presentations to the Next Level

As we enter year 700 of COVID-19, some faculty and staff are looking at 2021 wondering how they can spice up their online teaching environment without spending hours or days learning a full-blown video production application. While Zoom offers a wide range of ever-expanding features, there is still plenty of room for growth and mmhmm, a startup from Phil Libin, is capitalizing on that need.

First and foremost, mmhmm acts like PowerPoint steroids. You can supercharge your presentation by your webcam video overlayed on rich media content elements such as slides, images, videos, sounds, etc. Best of all, I was able to pick up the basics of the application in under 20 minutes or so, your mileage may vary. The easy drag and drop configuration nature of the application will have you creating or enhancing your presentation in minutes. Best of all, you can save your layout so that the next time you present, unlike Zoom, you won’t need to reposition your webcam feed, content location, etc.

Where mmhmm really excites us is its ability to feed that content into Zoom and a range of other video applications as a virtual camera or piece of content. While Zoom has enhanced a few features in this area over the past 6 months, mmhmm is considerably further along when it comes to rich presentations. On top of that, mmhmm is capable of capturing your presentation locally in a high-quality .mp4 video file WHILE also sharing that presentation with Zoom. Yes, Zoom can record the session, but sometimes you want a higher quality version, or you would rather not have the participants being a part of your recording. It’s the best of both worlds.

Finally, mmhmm has a copilot capability that will allow a remote participant to manage aspects of the presentation. This would come in handy when you have large productions where people are working together advancing slides. Perhaps not something for everyday use, but for power users… this could be a game changer.

Pros:

  • It just works!
  • Adds a level of sophistication to presentations, when you have the rich content
  • May allow for a better teaching delivery
  • Simplifies tasks that could take 30-60 seconds in Zoom (30-60 seconds doesn’t sound like long, but when you perform that task 20-30 times during a class, it’s an eternity)
  • The ability to save rich presentations can’t be understated… and is a feature lacking in Zoom. Having to “reset” your video layout can be problematic.

Cons:

  • The subscription pricing model is… well, expensive ($9.99/mo or $99/yr – no educational pricing to be seen)
  • mmhmm can consume a considerable amount of processing power. The fans on my MacBook Pro were screaming when running Zoom and mmhmm with advanced videos, etc. in the content box. I’m sure the new MacBook Pro with the M1 CPU won’t even blink.
  • You CAN do much of what mmhmm does with free and open source applications if you are willing to invest a good bit of time learning such platforms (which can be buggy at times), but mmhmm packages it up in a more faculty/staff friendly package.
