How can we make video more appealing to humans? We’ve evolved to live a certain way and this has defined – and will continue to define – our video technologies. MUX founder Jon Dahl talks to us here about the ways in which human physiology drives viewing habits.
Vertical vs. horizontal video, angular resolution and how the typical viewing distances of computers, TVs and other devices affects what resolution we can perceive are all discussed. Jon moves on to frequencies both of audio and video where frame rates and flicker are important and where physics comes into play alongside biology.
Even for the experienced, this talk is bound to bring something new and is a great tour of the fundamentals of the visual perception that our industry relies on and strives to please day in, day out.
This talk was given at Streaming Tech Sweden which is an annual conference from Eyvinn Technology. Streamed on their own video platform, talks are initially available exclusively to all conference attendees, but are released free-to-view during the subsequent year. Free registration is required to watch the videos.
Mux’s Justin Sanford explains the difference between Quality of Service and Quality of Experience; the latter being about the entire viewer experience. Justin looks at ‘Startup time’ showing that it’s a combination of an number of factors which can include loading a web page showing the dependence of your player on the whole ecosystem.
Justin discusses rebuffering and what ‘quality’ is when we talk about streaming. Quality is a combination of encoding quality, resolution but also whether the playback judders.
“Not every optimisation is a tradeoff, however startup time vs. rebuffering is a canonical tradeoff.”
Finally we look at ways of dealing with this, including gathering analytics, standards for measuring quality of experience, and understanding the types of issues your viewers care most about.
MUX is a very pro-active company pushing forward streaming technology. At NAB 2019 they have announced Audience Adaptive Encoding which is offers encodes tailored to both your content but also the typical bitrate of your viewing demographic. Underpinning this technology is machine learning and their Per-title encoding technology which was released last year.
This talk with Nick Chadwick looks at what per-title encoding is, how you can work out which resolutions and bitrates to encode at and how to deliver this as a useful product.
Nick takes some time to explain MUX’s ‘convex hulls’ which give a shape to the content’s performance at different bitrates and helps visualise the optimum encoding parameters the content. Moreover we see that using this technique, we see some surprising circumstances when it makes sense to start at high resolutions, even for low bitrates.
Looking then at how to actually work out on a title-by-title basis, Nick explains the pros and cons of the different approaches going on to explain how MUX used machine learning to generate the model they created to make this work.
Finishing off with an extensive Q&A, this talk is a great overview on how to pick great encoding parameters, manually or otherwise.

Encoding and transcoding are at the heart of every video service and solution, and the codec and format landscape has never been more crowded. Publishers are wringing the most efficiency out of H.264 while making the move to HEVC/H.265 and AV1—and keeping an eye on other proprietary codecs. On top of all that are considerations like video optimization, bitrate ladders, and per-title encoding.
Join this expert panel as they discuss the latest in encoding and transcoding, including the following:
The state of the art in encoding efficiency in 2018
How per-title encoding and machine learning can increase quality and decrease delivery costs
How to build flexible and cost-effective encoding solution
The latest developments in video encoding platforms and infrastructure
The benefits of contribution to distribution encoding and transcoding
The next big advances in encoding and transcoding, including AV1

Streaming Media are back with Bitmovin and MUX to talk about APIs.
After all, more APIs and SDKs than ever are available to developers, and they’re getting smarter—allowing businesses to advance their video development at a more rapid pace. APIs simplify everything from payment processing to content management, and SDKs allow for heretofore unheard-of customization for everything from formats and delivery protocols to player controls and features.
Learn how to leverage APIs and SDKs to grow your video business fast, as they dive into these issues:
How developers can use APIs and SDKs to build highly customized video streaming platforms, instead of relying on out-of-the-box OVPs
The implications and challenges of the APIs & SDK revolution for enterprise engineering teams
Best practices for relying on third-party APIs: testing, monitoring, etc.
What developers need to know about the video infrastructure layer
How to decide which video API fits your needs
What resources exist to help broadcast engineers, as well as “traditional” software engineers, advance their video development skills.
Practical advice on delivering video content live or over OTT.
By watching this video you’ll understand the pros and cons of all the elements needed. Matt Ward from Mux starts with a list of ‘what we need’ and goes through each one using personal experience to filter through the many options out there which can feel overwhelming. What actually are all of those options and how do you decide what to actually do? This talk will go into the details of how to make CDN decisions and actually improve the things that you once thought were out of your control.
