Video: Streaming Tech Sweden 2018 Keynote


To mark International Women’s Day these videos are free to watch, but for 3 days only! Free registration required.

To mark International Women’s Day, Eyevinn Technology have opened their premium archives to allow you to watch two videos for free until 11th March which are normally reserved for patrons of the Streaming Tech Sweden conference – so act quickly to watch Netflix’s Megha Manohara discuss Netflix’s dynamic optimiser framework and how they ensure best quality over a variety of bandwidths.

Megha covers encoding testing, metrics such as VMAF, visualising the results, per-shot encoding and the way they validate with their audience they have done a good job.

Streaming Tech Sweden is an annual conference which prides itself on excellence and independence. Without sponsors, they are free to pick the best and the most relevant speakers working on at the cutting edge of video streaming. The talks from Streaming Tech Sweden 17 are free to watch, but those from 2018 are available for attendees only. Later in 2019, they will become free, but until then, this is a short opportunity to watch these two great talks in order to mark International Women’s Day 2019. Registration with the site is free.

The second talk available from Streaming Tech Sweden 2018 is from Codemill’s Johana Björklund talking about contextual marketing and ad personalisation. Johana explains how the ads work, how GDPR has changed the way personalisation is carried out and how video metadata is used to find pre-roll and post-roll ads.

Video: VMAF – the Journey Continues

VMAF is a video quality metric created by Netflix which allows computers to indicate what quality a video is. This is an important part of evaluating how good your encoder or streaming service is so it’s no surprise that Netflix has invested years of research into this. Other metrics such as PSNR and MS-SSIM all have their problems – and let’s accept that no metric is perfect – but what the industry has long grappled with is that a video that has a strong fidelity to the source doesn’t necessarily look better than one that less-faithfully replicates the source.

Imagine you had a video of an overcast day and one encoder rendered the video a bit brighter and a bit more blue. Well, for that clip, people watching might prefer that encoder even though the video is quite different from the source. The same is true of noisy pictures where replicating the noise isn’t always the best idea as some people, for some content, would prefer the cleaner look even though some details may have been lost.

As such, metrics have evolved from PSNR which is much more about fidelity to metrics which try harder to model what ‘looks good’ and VMAF is an example of that.

Zhi Li explains the history of VMAF and explains some of the new features which were released in August 2018, when this talk was given, which gives an insight into the way VMAF works. Plus, there’s a look ahead at new features on the road map. This talk was given at a SF Video Technology meet up.

Video: OTT Moves Toward Microservices


 

Using microservices is a way of architecting your software platform to be nimble, simple and is just as applicable to on-premise platforms as cloud. As scaling is important for OTT providers, it’s not surprising that much work is being done in the OTT sector to utilise microservice architectures.

Even companies that are not yet actively operating on a microservices architecture are looking for vendors who at least have a strategy to cater to it for the future. This session will examine the core benefits (including redundancy, dev ops, scalability, and self-healing), the different approaches (including containerisation and orchestration via Docker, Kubernetes, and Mesos, as well as native microservices models like Erlang), and the complexities of migrating a generic architecture to a microservices architecture.

This panel covers:

    • Why is OTT so suited to microservices?
    • How microservices enable companies to be flexible to changing customer demands
    • How microservices reduce complexity
    • Benefits of continuous deployment

plus much more!

Video: Best Practices for Advanced Software Encoder Evaluations

Streaming Media East brings together Beamr, Netflix BAMTECH Media and SSIMWAVE to discuss the best ways to evaluate software encoders and we see there is much overlap with hardware encoder evaluation, too.

The panel gets into detail covering:

  • Test Design
  • Choosing source sequences
  • Rate Control Modes
  • Bit Rate or Quality Target Levls
  • Offline (VOD) vs Live (Linear)
  • Discrete vs. Multi-resolution/Bitrate
  • Subjective vs. objective measurements
  • Encoding Efficiency vs Performance
  • Video vs Still frames
  • PSNR Tuning
  • Evaluation at Encode Resolution Vs Display Resolution

Video: Beyond Netflix: How specialist streaming services can compete against global players

From the IBC 2018 conference, a discussion on how to compete against Netflix and the other global players. We hear from Britbox, Filmstruck, DAZN, ErosNow their ways of differentiating. Exclusive content rights is a key element in the strategy, but innovating around technical challenges is necessary to make it in the fray.

When the global players have to be everything to everybody, what gaps in her need does this leave? DAZN’s Chief Product Officer Ben Lavender explains their sports rights strategy and how they ensure sustainability. DAZN are constantly fighting to reduce latency. Ben describes the work they’ve done over the years to reduce latency by a third.

Ali Hussein gives us the Indian perspective whilst Soumya Siraman explains why the British experience of Britbox is a hit with her US customers. Kerensa Samanidis makes the point that FilmStruck’s ‘quality cinema’ principle will mean different things in different countries.

Video: Lights, Colors, Artwork


Mark Watson from Netflix examines how to combine SDR and HDR video from many sources into one seamless experience. How do you manage the different colour spaces, the difference in dynamic range, the types of HDR? Mark talks about how the different delivery formats differ and presents ways in which they can be unified, representing the work that Netflix is putting in to create a rich, seamless and dynamic auto-playing user experience.

Video: Streaming at 250 kbps – raise your expectations


Megha Manohara discusses Netflix’s ongoing efforts to reduce the bitrate of movies whilst maintaining their enjoyability showing their success right down to 250kbps.

As a Senior Software Engineering on Video Algorithms, Megha’s talk focuses on the research and implementation challenges of Dynamic optimizer – an innovative shot-based encoding tool that raises the perceptual quality of streams at bitrates as low as 250kbps. Visiting VMAF, PSNR and other metrics on the way, this talk gives great ideas on reducing bitrate and measuring success.
