Welcome, we're doing lightning talks now.
So the way this is going to work is that we have six speakers,
each of whom have five minutes to tell you their story.
There's some technical challenges.
We're gonna try to move it along briskly.
We'll try to take one question between each speaker while
the other speaker comes up and gets ready to go.
If there's time at the end, then we can do more questions for
any of the speakers, okay?
Okay, the first speaker is Nate and.
>> Peter.
>> Thanks, Ned.
>> [APPLAUSE] >> Hello everybody.
We're gonna talk about a new video XBlock for Open edX.
So my name is Nate Aune.
I'm with Appsembler and this is.
>> Peter Koblyakov.
>> Peter, from Raccoon Gang >> So what's the problem?
Well if you've used Open edX before you probably noticed that
the default is YouTube.
The problem with YouTube is that your videos are not protected
when you put them on YouTube.
It's an advertising model meaning that even if it's unlisted they can
get the URL, they can share that URL with their friends and
your IP is now in the public domain.
The other problem is that the S3 videos, you can only have one.
Which means if you wanna have one video that's optimized for
mobile, another video that's optimized for desktop, you have to pick.
So the video player can really play only one video.
The other problem is, if you use, let's say Brightcove or Wistia,
they'll give you an HTML embed code that you can drop in your Your Open edX site.
But that video player's probably not [COUGH]
compatible with the built in player.
It doesn't have the same features.
And you have these embed codes sprinkled all throughout your Open edX site.
So if the API changes you have to go through your entire course and
replace all those embeds with something else.
This is a problem that was affecting a lot of our customers and so
we put our heads together.
We said what can we do about this?
And two of our customers stepped up
to sponsor what we call the feature sponsorship model.
So they're basically cost sharing the development of a new video ex block.
We got together with Raccoon Gang who had some experience doing videos in Open edX,
so they were our development partner.
And we're gonna show a short video of the functionality of the new video XBlock.
I'm gonna hand over to Peter.
>> Yeah, I will do some comments.
So we can make an XBlock.
We embed just the URL of the YouTube and it's simple.
We have all the features edX player has.
Now we can just get the captions and
transcripts from YouTube.
And director's transcripts as well.
[COUGH] So the functionality is basically the same.
We can put Wistia, it will work like the same as YouTube,
we can do that with Brightcove, With vMail.
Here is the dog.
The Brightcove is the most cool one.
I will tell you.
Because we have integration with [INAUDIBLE] play media.
Which is the place you can handle your transcripts.
Here how we can embed it.
You can see the transcript appeared.
And the most crucial thing is that we can now encrypt the video only in Brightcove.
Which is real important for the corporate clients.
And basically, we can see that now video is encrypted.
>> [INAUDIBLE] >> I have another slide
Yeah, we have one slide.
Yeah so, very short.
We have support of YouTube, Wistia, Vimeo, HTML5.
We have a new feature with the integration of three play media which is cool for
corporate clients.
We've touched all the features video in edX has, speed up speed down.
Set start and time accessibility features.
Interactive transcripts and captions and handouts.
>> So how can you get involved?
If you're a course creator we have a demo site where you can play around with
it, try it out.
If you're a developer the code is up on GitHub.
We welcome patches, and new features.
If you would like to fund the development of other video hosting providers or
new features, come talk to us.
And lastly we're having a birds of the feather today at 3 PM, and
there's a video blog post, if you want to get more information about it, thank you.
>> Thank you.
>> [APPLAUSE] >> Hi, I'm Regis.
Let me just ask you one question, where do you host your videos?
I'll answer that for you.
Perhaps you store them on YouTube,
perhaps you store them on Vimeo or elsewhere, I don't know.
Well I am here today to tell you one thing, get your videos back and
host them yourself.
Really, it's not that hard.
And then you're gonna ask me, but why would I want to do that?
YouTube works really well.
Well, I have just one single reason to give you.
It's a pretty big reason.
Listen carefully.
Video is a core component of online education.
You absolutely must get it right.
Without video, you don't have online education.
And if you get to trouble of hosting your own MOOC platform,
yourself, why not host your videos?
Really, it's not that hard.
So really, you cannot compromise on video.
What cannot you compromise on?
Basic features.
You can't compromise on multiple resolutions,
you can't compromise on just adjustable play speed, clickable video transcripts.
But more importantly, you cannot compromise on downloadable files for
offline viewing.
This is crucial to the learner experience so that they can view videos offline.
And this is not possible on YouTube, as you know.
You can't compromise on 100% accessibility.
What does that mean?
That means accessable all the time and for everyone, not just 80% of the world.
I'm looking at you China and YouTube and.
And here I picked on China, but it's also true for many countries.
At that point, you might be thinking this is going to be hard.
Hosting my own videos?
I don't know how to do that.
I would like to tell you one thing.
It's going to be fine.
Get rid of YouTube, really.
All you have to do is three simple things.
Very easy.
First, install Videofront.
This is a new project, it's a Django project.
Small, about 3,000 lines of code that provides an API.
And where you can upload your videos.
It's great.
Then you have to plug to it with a custom XBlock,
called a Videofront XBlock which is also open source.
It's based on video.js.
And the third thing that you must do is send me your credit card number.
No.
So yeah, everything is free.
But it's actually, [LAUGH].
It's actually no but, yeah, seriously.
So video from how much does it cost?
So it's a pretty important question.
In order to understand what it cost you have to understand what is video hosting.
Video hosting is three things.
First, it's storage on disk.
Then it's transcoding to multipurpose solutions, that is CPU bound.
And then you have streaming, which is delivering the videos to users.
This is related to bandwidth.
The cost of the first two items is a function of the number of videos.
The cost of the third item is proportional to the number of users that you have.
Okay, so how much is this going to cost you?
Well, if you make a graph with a number of videos and users.
Okay so maybe you have a personal blog.
It's here.
You have few users, you have few videos.
On the other hand is YouTube.
YouTube has many users, many videos, very expensive.
You don't want to be them.
And then at the bottom right, many videos, very few users, MySpace, I don't know.
But you, you are there at the top left corner.
You have few videos, because you're a Mooc platform, but you have many users.
So the cost is not going to be that much.
Let's break this down into numbers.
Let's say you have a course with 20 videos, 10-minute videos.
You have 1000 users that view all videos every month.
This is an assumption.
And then, how much is this going to cost?
So you can use two different backends, let's say.
You can store everything on your own servers.
This is what I call the local backend.
So I made the math, it costs about 10 Euros per month.
So you will have all the slides on the GitHub afterwards.
So the 10 Euros, this is per month per 1,000 users.
I call that the Gold plan.
Then you could use a backend on AWS with all nice servers that they provide.
This is what I call the Platinum backend, it's more expensive.
This is again a price per a thousand users per month per course.
And the great thing is that Videofront supports both of these backends.
Actually Videofront was developed so
that you can use, you can create your own custom backend.
So you can have a custom backend with the best of both worlds.
And then you have a pricing that is dependent on what you pick.
I call that the Double Rainbow plan.
Okay at that point you might be thinking no so seriously a bandwidth.
I am a video provider.
A bandwidth is going to be very expensive.
Well good news for you.
Sorry about that.
So the required average bandwidth is 5.3 megabit per second.
But today, a server comes for free with 250 megabits for second.
So this is great news.
Will it scale?
Seriously?
Well Videofront has been in production on Fun Mooc.
I don't know if you heard about Fun Mooc.
It has 1 million users, 300 courses Videofront has been running for
eight month and it has been running great.
That's all I got thank you very much, migrate your videos today,
get in touch, I'm Regis.
>> [APPLAUSE]
>> Okay Regis can help him [INAUDIBLE].
Just so Regis mentioned it but all of these slides, everything's being
videoed and all the slides are gonna be made available afterwards so you don't
have to try and capture these things as Regis flies by them on the screen.
>> So thank you very much.
I'm going to do this slide and talk in Spanish.
No, no just kidding.
Just kidding.
So I'm going to talk a little bit about the video.
I'm the developer and the founder of IBL Studios,
which is of course production company, New York.
We also do Open edX deployment and
I'm going to talk how to film at a scale by using the latest technologies.
So last year we got this engagement.
We needed to produce two courses per month in all these subjects.
Introductory level courses, thirty hours, forty hours courses.
And the requirement was very clear.
You need to put yourself these courses.
I need at least six to eight hours of video.
You need to hire 25 plus professors from top schools.
So I say, okay, how can we do this?
Efficiently and in a minor way.
So we say, well the first thing, the very first thing,
the real answer is no post production.
How many videographers in the room?
Okay, know you what, you know the pain of post production.
Post production takes time, and time, and time.
So you say okay, let's get rid of post production.
Forever. Let's produce everything in real time.
Not streaming but in real time.
So mixing cameras, many cameras, laptops, iPads, everything in real time.
The second point was key.
We needed to have always a top instructors.
That means train them well, and obviously,
we need to use all the very latest technologies available in the world.
So we install our white cyclorama, any an idea what is a cyclorama?
It's a huge infinite background.
I will show some pictures here.
We needed to use light board.
light board is like writing in the glass.
A nice piece of technology especially well for
STEM courses and in terms of green screen we wanted to
use CN style the latest technology meaning avoiding that kind of
a green glow that you see when you do green screen, so.
Obviously a 4K.
Even if it's YouTube, you need to do 4K, because the quality is much more better.
iPad, I know that our technologies, but
we say okay, iPad works very well, works the best for
the kind of descriptional design, and obviously audio is key.
This is the cyclorama that I am talking, it allows any professor
to not only be in stuck in a podium but walk around the whole room, right,
because at the end they would like to do teaching is this way.
So this is the light board.
And by the way anyone can install a light board,
it's open source it's an open source technology.
But you're gonna need to have a lot of equipment and
specially dedicated studio for the light board.
Because as you can see you need a black background.
This is the control room and from this control room we are using all the studios.
That was the white cyclorama.
The other one is the, the other studio with a light board.
So you need to have a very well coordinated team.
People say team, team, team.
Yeah.
Always best at professors, instructional designers, videographers and engineers,
cuz at the end,
it's not only creating the courses, you need to create an interactive experience.
So this is a shot of the studio, that's a biology course.
And that's the view of the professor.
The professor is using the iPad but at the same time, following their notes,
you need to create a situation where they all feel extremely comfortable.
This is one of the team of the courses and
I want to show a couple of videos produced in real time.
They say real time is low quality, it's a guy with a little camera.
It requires a lot of pre-production.
You don't have post production but you need a lot of pre-production.
So maybe this one is the first one, or that is the second one.
Yeah, that's fine.
So this is the intro.
The intro to a precalculus course, we need the sound,
so we have the professor talking in real time and
obviously we've prerecorded video.
We are adding all of these images, you may say no, no way, this is post-production,
you're kidding me, believe me, this is all real-time production.
So when you are producing at a scale massively, you need to produce in
real-time, exactly the same way that the television business works.
If you go America's Got Talent or any other program, it works this way.
So let's just say you wanna do courses at a massive scale delivering a couple of
courses per month you are gonna need to do live productions and that's all.
>> [APPLAUSE] >> Sure, the question was if you
wanna try out the Video XBlock on your own Open edX instance, how would you do that?
So you would download Video XBlock from GitHub, installed in your local edX
instance, and then for the course where you wanna use a Video XBlock.
You would add that to the advanced modules, and then it will show up under
Advanced, the little beaker icon, you'll see and do a thing there called Video.
>> Hello I'm Jeffery Cross and this is, >> Srigato.
>> We're from Tokyo Institute of Technology, and we'd like to tell you
about TokyoTechX's training program utilizing online resources.
So I know this is a video session, one of the challenges with the video is,
how do you train people to make videos using the online resources?
So we'd like to take about that, first I would like to introduce TokyoTechX,
we joined edX is 2014, we've created three MOOCs.
Our average MOOC development duration has been about 18 months for various reasons.
We have a number of faculty and staff and we work with about 25 TAs.
Here's our MOOC production model, in this case we have staff and faculty and
of course, instructor, and the TAs do most of the work.
>> So our fourth MOOC, which was on Science and Engineering Ethics,
we developed TA training in order for us to speed up our MOOC making process.
So this is a question we wanted answers throughout the MOOC making,
how do we train TAs effectively to develop a MOOC?
So in order for us to answer this question, we divided the TA training
topics into two, which was content creation and video production.
So those two are the teaching method that we use, online resources and
then Hands on Workshop.
>> So you can see our video studio here, or you could.
There's the professor and a TA recording in the studio, and
you can see our control room, and those are the TAs there.
So with online content creation, we use online resources to train the TAs,
next, and then we created several SPOCs to teach students.
And then some of those students became TAs, so we used SPOCs and
we taught the students how to create learning objectives, content assessments.
We taught them how to use edX Studio, we took materials from various sources,
and we had an agreement with Stanford.
And we used their Creating Effective Online and
Blended Courses, and we also translated that into Japanese.
As far as the hands on workshop, what we did was we,
Again we invited a speaker to give a workshop,
in this case the title of the workshop was.
From Ideation to Innovation, How to Create an Effective Online Course.
This is taught by Stanford's Dr Grace Lyo,
she's the director of digital teaching and learning at Stanford.
So you can see several photos shown here on the right, this is during the workshop.
We had some of the TAs working on creating the online course and
on the bottom, the TAs who were actually presenting their ideas.
In addition, Tokyo Tech, Kyoto University, and
Osaka University also participated in our workshop.
As far as video production, when we got started with this several years ago,
there wasn't a lot of online materials so we used what was available.
We had the students actually create marketing and educational short videos.
The instruction was from pre to post production, and
there's the SPOC over there.
And we used these materials and then we supplemented that with guest lectures.
As far as the Hands on Workshop,
in this case the learning objectives were for the groups.
To actually create short videos and
to work with experts to acquire the video special skills.
So the Hands on Workshop consisted of three days, and
we had a group from Hollywood come.
And we had 25 participants, and
then we gave the group that prepared the best video an award.
>> So, we created our ethics MOOC in about seven months And then,
we believe this was partially due to the TA training that we implemented.
Through this MOOC industry, also through this TA training we have
learned that customizing online resources is very important.
And then also that having a group of TAs to complete the online training allows
a MOOC team to share a common language.
And then also then lastly, in our case it was Hands on
Workshop boosted the TAs competency and also the motivation.
Thank you.
>> Do you wanna take a question?
>> Sure, thank you very much.
>> [APPLAUSE]
>> Okay, hello one more time,
I am from Russia, and I don't know what I'm doing in the video section.
But I want to share with you some experience about scaling proctor exams.
Some background,
we're speaking about national platform of Open Education Russia.
There are top nine universities, a huge amount on students and courses.
And right now, this is the only one platform that can give you credits for
your courses if they passed in the protectorate mode.
So, we do need proctoring, and this year we have the aim to scale proctoring
students for 10th time than the last year.
And there are some problems and solutions that we have found on this pass.
First, there are students often late for their proctoring exams, and
they are trying to make to another time and so on and so forth.
So we have to create our own schedule mechanisms,
use it over a multi proctoring solution.
That has been developed with our friends from also.
And give the students ability to change the time even before an exam, and
it worked.
And it helped us really, to scale the number of exam which is going in one time.
The second problem is that we have very different courses, from art,
from mathematics, from physics.
And from the different universities you have different rules for the exams,
on one exam you can use a calculator or piece of paper.
On other exam you should know everything from heart, so we need to add
some additional info and parameters for each exam and each type of exam.
For proctors to understand what a learner could do and
what he couldn't do during the exam.
From some universities, professors don't trust proctors,
they want to be proctors by themselves on some exam.
So we have to give them ability to be as a proctor at exam or
revise the proctoring exams by the representatives of the university.
In this configuration we have educational platform and the support we have
proctoring and then support and then we have university and then support.
There are three groups of people and
after a half of a year of Hat processes when they have some,
that we have to create some special requirements or how they should interact.
We have created them and their life become much more easier.
And of course cost efficiency pushed us
to create the mechanism to lowering the price of the proctoring because right now,
on the real time, proctoring is affordable if you want to get credits.
Not offline proctoring asynchronous, only online, so
that is why our colleagues trying to create some different solutions for
cyber proctoring and so on and so forth.
And at least we managed, we have multipled the number of students this year for
tens time than the last year.
So that I want, all that I want to share.
Thank you very much.
If you have question about scaling proctoring,
ask us or our friends from thank you.
>> [APPLAUSE] >> While
we're switching laptops any questions for any of the speakers, so far?
None no, okay.
There we go.
Good afternoon I'm [INAUDIBLE], I'm the CEO of [INAUDIBLE] Video Research.
We are a company focusing on solutions,
specially on open solutions for
online video to support teaching and learning.
We have customers worldwide, and
today I would like to talk about, this is the usual workflow.
You have to produce videos,
usually you upload videos to YouTube and then you publish videos on Open edX.
This could be exhausting and unsecure many times.
And what if we can provide our professors a way to manage their videos and
even to produce their videos inside of Open edX?
Well our proposal is something like this,
these are the outcome of three open projects working together.
One for the recording, the second one for the enrichment, and
the third one for media management.
Talking about recording, the solution is Galicaster, it's called Galicaster.
This solution what it does is to record two or more synchronous streams,
typically a separate video from professor and a separate video from the screen.
This is just a software with a regular PC that you can place elsewhere,
somewhere you have the two screen recorded.
It generates a touch interface so
professor in the classroom very easily can trigger the recording and manage it.
You can have in your classroom something like this.
You can also integrate it in via conference rooms,
in theaters, you can also build recording studios based around this.
There are many institutions worldwide using this open solution.
But I will also present a version of this embedded on Open edX.
To enrich this is based on Open Cast a project at the time led by UC Berkeley.
It creates this user experience, it index the videos, it extracts text from
the slides but it can also recognize for instances QR codes on the slides.
For instance this slide will be removed because it indicates
that it's copyrighted material.
This one can assign a chapter mark so the video can be then cut automatically.
To publish where you seen PuMuKIT.
PuMuKIT is a YouTube like thing, but also interacts with Moodle, Open edX and so on.
Many institutions are using this solution for instance, [INAUDIBLE].
This one University of Cologne in Germany, others in UK, United Nations.
This is all open source.
To create this magic, you have to install a PuMuKIT bundle and an Open edX XBlock.
You would also be able to embed YouTube videos, of course.
And if you want to learn more, there are the URLs.
And now we'll try to showcase you this user experience of the integration.
So, Here we are.
We are in the Studio.
New green button here, video is coming from PuMuKIT,
here just clicking it, this is the default video.
It's an Xblock that is able to videos you can,
>> [INAUDIBLE]
>> You can manage the video, but
of course this is the default one.
You can edit the video here, you can now add the URL if you have it.
You can also upload your videos right from here.
Professor Grant managed his library but he can also record here his own video.
Just have to activate camera, activate the screen sharing.
For instance, this application, I will give it,
I will trigger recording, it's recording.
Hello, here I am.
This is enough.
I stop recording.
It will upload the thing.
Okay and now I Save, and if everything is worked,
here I have published it on my unit the new Stream video.
>> Are you recording, are you recording hello, there I am.
>> And there it is.
[LAUGH] Thank you, that's it.
[APPLAUSE].
>> Not only a five minute lightening talk but
a live demo in a five minute lightening talk.
Okay, thank you all for coming, we are out of time, I hope this was helpful.
We have Birds of a Feather sessions later on this afternoon.
And this might be a good time to find these people and
ask them more questions about what they've built.
Thanks for coming. >> [APPLAUSE]
