mimoLive: Live Video Production Studio in your Office or Living Room

For those of you who use tools like Wirecast as the centerpiece of a low cost live video production studio, there is a new player on the block. Boinx Software hosted a live stream today that showcased mimoLive, the successor to BoinxTV and the results of months of work in conjunction with a large beta-testing community. MimoLive is basically a broadcast studio for your Mac. It now natively integrates with Blackmagic devices, including the UltraStudio Mini ($150.00) and the UltraStudio 4k (~$950.00), and Magewell and Epiphan were also specifically mentioned as offering compatible products for those who want more advanced switching capabilities and/or the ability to integrate more than four simultaneous video sources.

One of the biggest updates showcased was the addition of a plethora of built-in live streaming options, including:

  • Wowza
  • Any other rtmp streaming server
  • Facebook
  • YouTube
  • nginx
  • UStream

The central element of the mimoLive layout is layers, and in fact the UI looks and operates a lot like Photoshop. Clicking on different elements uncovers extended palettes in a way those who like Adobe products should find intuitive. Sources are selectable on the left and outputs on the right, including the live options listed above plus the ability to record to disk, now with more codecs, including ProRes 422 or 444. 444 supports an alpha channel, so things like lower thirds and graphics maintain their editability after export. The layers are stacked like in Photoshop so that what is above hides what is below. They mentioned there is a third party integration that provides better visibility in the UI down through the layer stack but weren’t able to show this during the demo.

To begin a project, you select a template, choose your dimensions and frame rate, including plenty of options for mobile devices, and then begin working with your layers. Options include graphics like logos and lower thirds, and numerous external elements, including weather layers and Twitter or other social media feeds. One of the cool new features demoed was the new ability to edit many of these elements directly from the preview window–i.e., you can click and drag the lower thirds or logos to size them rather than entering pixel dimension manually like before.

Also new is play-out to an external player like the Blackmagic UltraStudio 4k or your ATEM Television Studio via SDI. This includes motion graphics plus their fill and key signals.

Right now, one down side compared to Wirecast is that you can only stream to one destination at a time with mimoLive.

Another change is how licensing works. All licensing is now subscription-based, with pricing that ranges from $19.00/month for personal licenses up to $199.00/month for enterprise usage. They mentioned that this will allow all users to take advantage of the fast update cycles they are planning. Their plans for the product seem ambitious–they even specifically mentioned that they want to support live 360 video with placing of objects in different parts of the “frame.”

One user asked about Integrating Skype and specifically Skype audio, and the presenter indicated this is easily done through a combination of video capture and a virtual audio router to get the audio from Skype into mimoLive

50% off Single EDU Licenses for Camtasia and SnagIT until June 10

TechSmith recently announced that they are ending support for Knowmia, a video recording app for iOS which allows users to record videos that can then be uploaded to Knowmia.com, a searchable learning object repository. TechSmith, which expanded its array of products and services in recent years (https://www.techsmith.com/products.html) will also discontinue support for ScreenChomp, the Teach apps, and their Google Chrome browser extension. They indicated this move will help them increase their focus on flagship offerings Snagit and Camtasia. Their plans for lecture capture app Relay weren’t mentioned in the announcement, which can be found here.

In conjunction with this announcement, Relay is offering a 50% discount for single edu licenses purchased through their web store until June 10, 2016.

Knowmia allows creators to describe and tag the videos by topic, define target teaching grades, and share them via public links and embed code or through social media. It seemed to have strong application in K-12 where teachers may not have access to enterprise level tools at their own schools.

New Progressive Download Capability for Warpwire

One of the cool features we rolled out out in our last major Warpwire upgrade is an option for progressive download. This work has grown out of our involvement with Duke global programs, such as our campus at Duke Kunshan University. Specifically, we’ve noted that in situations that combine low bandwidth with high network latency, we can reduce video buffering and significantly improve the end user experience by delivering the files via progressive download rather than the standard HTTP Live delivery method Warpwire currently uses by default.



We’ve updated our Warpwire FAQ (https://duke.service-now.com/kb_view.do?sysparm_article=KB0017639) to reflect this new capability as well as to include minimum technical requirements for using Warpwire. I’ve clipped the relevant info below:

What are the minimum technical requirements for using Warpwire?

Network Speed:
  • Viewing videos at 360p requires 1.0 Megabit per second
  • Viewing videos at 480p (SD quality) requires 3.0 Megabits per second
  • Viewing videos at 720p (HD quality) requires 5.0 Megabits per seconds
Latency (sometimes called “ping”):
To stream videos effectively via Warpwire’s default method (currently Apple’s HLS protocol), your network latency (“ping”) should be no greater than 150ms.
Test your network speed and latency (“ping”) here: http://www.speedtest.net/)

My Warpwire videos keep buffering. What can I do to improve performance?

If your videos keep buffering (i.e., showing three moving dots on top of the video), test your network connection for bandwidth and latency via http://www.speedtest.net/). If your bandwidth and/or latency are close to our minimum recommended thresholds, switching the media libraries to Progressive Download may help. To do that, contact the OIT Service Desk (oit.duke.edu/help) if you own the Media Library or Libraries containing the problem files and provide the name and URL of the Libraries in question. If you are not the owner, contact that person (the person who shared the files with you) and request that they contact the OIT Service Desk to switch to Progressive Download or make other arrangements to share the file/s with you.

Please note that if you do not have a bandwidth of at least 1 Megabit per second, your best option may be to request that the owner of your Media Library or Libraries move the files to Duke’s box.com site where you can download the videos and view them on your local hard drive.

Warpwire 1.6 Update

Great news! The talented team at Warpwire together with OIT Media Technologies implemented a significant upgrade of Warpwire (v. 1.6) at Duke last week that adds a number of eagerly-anticipated features.

Warpwire Secure Media Publishing

These new features include:

Closed Captions:
– Added ability to upload closed captions in SRT format for any video asset
– Closed Caption icon is present within the video player for files with associated caption metadata
– Simplified sharing by consolidating the “Share secure link or Embed” and the “Share with Users and Groups” into a single share interface
– Added the ability to promote shared members within a Media Library to administrators of the media library
– Sharing with groups and users now use the same search interface and are threaded within the results
– Share link, embed code, and scripts are visibly more distinctive and now automatically select the link text on click
Removing Media:
– Revised workflow for media removal to allow for automatic deletion from all shared locations
– Removing media that is only present in a single Media Library will permanently remove the asset
– Added the ability for users to assign ownership of a media asset to a different user

We are very excited to be able to offer you these updates.  The Warpwire team is continuing to actively develop their product in part based upon our (i.e., your) input, and so we are eager to hear how Warpwire is working out for you as well as to hear what additional feature requests would be useful for you and the teams, departments and programs  you are a part of at Duke.

For more information, and to start using Warpwire, just visit https://warpwire.duke.edu and log in with your Duke NetID. Feel free to reach out with any questions.

Duke Has a YouTube-like Video Publishing Tool!

Some of you have been following OIT’s three year search for a replacement for our antiquated DukeStream servers. We searched diligently for something super easy to use and that would integrate seamlessly with our identity management systems so that users can secure videos based on Duke NetIDs and groups. Finally, after spinning our tires with the 500 pound gorillas in the industry, we found three Durham-area developers (developers of Voicethread) who basically built the system, called Warpwire, from the ground up to our specs. We first told them about our need for this type of tool on January 8, 2014. In just a few weeks they gave us an early demo of the system’s core security features, and on January 8, 2015, we went live in production. Only one year! Multiple teams within OIT collaborated with the Warpwire developers to make this happen, and we’re really thrilled to be able to introduce this tool to the Duke community.


Anyone with a valid Duke NetID can log in to Warpwire and start using it (go to https://dukestream.duke.edu/ and click the yellow button that says “Log In.”)

A few highlights to mention:

  • Warpwire is easy to use.
  • Warpwire’s asset level security means that it will honor viewing permissions no matter where or how you choose to publish your media.
  • Warpwire supports photos/ images in addition to video. (Audio only files are coming in a later release.)
  • Warpwire’s interface is designed to function (and scale gracefully) across mobile and desktop browsers. You can upload videos and photos right from your iOS device to Warpwire.
  • You can also record videos right into Warpwire on your iOS device.
  • Warpwire is fully integrated with Duke’s production Sakai instance through a custom LTI integration.
  • There is not an option yet to share with All Duke NetID Holders (as one unit) or to make videos public, but those features will be announced soon.
  • Did I mention Warpwire is easy to use?

There is documentation to help users get started (as well as other information about streaming at Duke, including Wowza Media Server for live streaming) at https://warpwire.duke.edu/.

Please note that Warpwire cannot be used to distribute or store any media that requires HIPAA or FERPA compliance.

Please feel free to kick the tires, let us know what you think, and help us spread this exciting news!

Streaming Deployments in Higher Education at SM West, 2014

Screen Shot 2014-12-04 at 3.11.25 PM


I attended Streaming Media West in Huntington Beach, CA this month and got a chance to brag about DukeStream and DukeCapture there on a panel called Streaming Deployment Architectures in Higher Education. The session Moderator was Chris Knowlton, Vice President and Streaming Industry Evangelist for Wowza Media Systems, and the panel included representatives from USC Sol Price School of Public Policy, Berklee College of Music, and UC Riverside. The video for the session was just posted and is available below, and I’m planning to post more information about the conference in the coming weeks.

I was intrigued that of all the schools on the panel, Duke was the only school with a coordinated, central video strategy. Most of the other schools were completely decentralized, with the panel participants working solo in individual schools and departments. I felt privileged to be a part of this talented group of speakers and enjoyed hearing about their roles and various projects they coordinate at their schools.

To whet your appetite for watching the video, I wanted to highlight a project called Lola by panelist Ernest Gillis from Berklee College of Music. Lola is a home grown system based on Internet 2 that offers 110Mbps up and down for synchronous video collaboration where musicians in different states perform together in live broadcasts up to 800 miles apart. The system is not currently HD but allows them to remain in synch with less than 30 milliseconds delay. You can find more details about this project in the video above.

Session description:
 Video in the classroom isn’t a new concept, but as streaming media becomes a mainstream staple in the household, it’s only natural for the technology to trickle into education. This session explores how universities are bringing live and VOD streaming into the classroom, including a closer look at how it’s being deployed (with architecture diagrams), which use cases are showing the best success, and best practices that should be followed.
