Keynote: What idiot designed this?!

A tongue-in-cheek stroll through the history of video standards.

Phil Cluff (Brightcove)

What's in the box?!

You probably use MP4 containers every day, but do you really know much about what's inside them, and what changes as we start to use FMP4 delivery online? This session will dive into the MP4 atom structure, and how it has evolved for ISO BMFF format for FMP4 content. We'll look at tools you can use to dump, explore and fiddle with information in your (F)MP4s.

Other browser APIs that are going to change video on the web

MSE and EME aren't the only browser technologies that will affect how we deliver, process, and play back video on the web. This talk will explore tangentially related APIs in the early stages and how we can use them to improve (read: complicate) web video.

Delivering HDR

HDR - awesome buzzword, noticeable lack of consensus around what it means, much less how you can get it into your home. In this talk, we'll go over the state of the industry, make some informed predictions on how things are going to shake out in both the near-term and farther out, and take a look at how you (and your viewers!) can see HDR some time before 2018.

Decentralizing Video Streaming

Today almost all technology relating to video streaming works on the server-side: ingestion, encoding, packaging, caching, content delivery and more. Video consumption growth and higher bitrates have been creating issues for many video publishers, causing them to explore alternative technological opportunities. New client-side APIs that leverage the end user's capable, untapped computing power are just the solution. We'll talk about the benefits of using client-side solutions instead of server technology and discuss the issues associated with operating this type of architecture.

Owen Edwards (SSB BART Group)

It's just captions, right? Why does video accessibility matter in the 21st century.

Video continues to grow as a major source of online information, education, entertainment, and social engagement. With web content facing increased scrutiny under accessibility regulations including the Americans With Disabilities Act (ADA), Section 508 of the Rehabilitation Act and its upcoming Refresh, and the 21st Century Communications and Video Accessibility Act (CVAA), what do video techologists need to know? Can't we just turn on auto-captions and be done with it??

New video coding techniques under consideration for VP10­ - the successor to VP9

Google has recently embarked on an ambitious open-source project to develop a next generation royalty-free video codec VP10 that achieves at least 30-40% bit-rate reduction over the current generation codec VP9. While the project is still in early stages, a set of new coding tools has been added to baseline VP9 to achieve at least about 6% coding gain already over a large enough test set. This talk will provide an in-depth technical overview of these coding tools, along with information on how other parties can be involved in this project.

Digital El Mariachi the Beginnings of Cinema Workflows for Online Video

What El Mariachi did over 20 years ago making a film with a budget of 40K as a catalyst to launch independent cinema mainstream is happening again online. We'll challenge the audience to move past the term "broadcast quality" as the benchmark to beat for online video. Technology advances have now made it possible to make cinematic workflows practical for almost any video professional. We will focus on how to create a chain of command from pre-production to distribution that puts your content on a level playing field in terms of production value with the largest production companies in the world.

Eliot Miller (DaCast)

How to even camera

Ever stood there, with that lump of metal and flashing buttons in your hands, turned it over and said to yourself: "How do I even 'camera'?" We'll cover the basics of filmography, covering composition, lights and a bundle of cool tripod tricks in a fun and engaging way (Yes, there are "cool" things you can do with tripods).

And moar! (Assorted)

Lightning talks

We're opening the floor for lightning talks! We've already confirmed some of the best submissions we got, which include Seam Carving, a personal apology to vertical video, Getting Started with ExoPlayer, Surviving the Flash-pocalypse, and more!


The specifics of the schedule are subject to change.

To be terribly honest, we're simply engineers talking about video technology. After two years of chatting about video at the SF Video Technology Meetup, we've decided it's time for an engineer-first event with quality technical talks about video. Our focus is on video delivered over the web, but topics cover anything from encoding to playback and more!

Our guiding principles

No Marketing. Speakers are selected based on merit, not how much money their company paid. To be clear, that means speaking slots aren't for sale. Attendee information is also not for sale, and that includes any sponsors.

Affordable. We want anyone in the industry to be able to come! In order to do that, we keep tickets reasonably priced through amazing sponsors and corporate backing from our employers. Working on some great open source project that still can't afford to send you? Please reach out and we'll find a ticket for you.

For everyone in the industry. In keeping with our love for reasonable standards, we're adopting the Conf Code of Conduct for the event. Have any questions or concerns? There will be people wearing t-shirts at the event that mark them as volunteers or organizers, any of whom can either help or find someone that can. If you prefer, you can also email us directly at any time.

Community. We strive for high quality, technical content, but just as importantly we're trying to use these events to strengthen our community of video engineers, both in the Bay and at large.

Who's organizing this?

Most of the boring work is being done by engineers from Brightcove, but there was an amazing group of people from the meetup that we called our "Braintrust." They've been nice enough to do things like schedule planning, vetting the conference name, designing cool swag, and even arguing heatedly over which talk submissions should make the final cut.

This event is run with the help of the members of the SF Video Technology Meetup. We're incredibly lucky to have built up a community of engineers that work on some of the best video products on the web.

SF Video is made up of engineers working on amazing products such as...
