Prezi in HTML5

  • Idea
  • Updated 5 days ago
  • Under Consideration
HTML5 Prezi embeds. I realize the whole application probably needs flash to create Prezis, but as far as I know you should be able to display prezis on other websites (the embed) as HTML5. This would allow those on phones or ipads to view presentations.

I hate to say it but lack of HTML5 embed is a dealbreaker for me. I was seriously thinking about signing up for a Pro account but not being able to view an embedded Prezi on an Ipad or iPhone made me hold off.

Any plans on rollout? Is it in the pipeline or just under consideration?

This comment is 3 years old. Has this changed? We won't use prezi in our product as long as flash is required. It appears it still is.

I think moving to HTML5 would also help with accessibility issues, but I'm still researching that. Using prezi instead of ppt means we have to also produce the ppt anyway, because prezi isn't accessible and we're required by law to make an accessible version available at the same time. So if HTML5 is more accessible, that would be a huge help!

Sandro,
we have no plan for this. Sorry. It will be available on android since it has flash support.

Rochelle,

what accessibility problem can you see? We can solve that without HTML5. Can you help in specifying what you need for accessible version?

Screenreaders can parse a prezi, can they?

My colleagues have been in touch with you with a list of accessibility problems, I'm sure I could have them send the correspondence on again if you like.

hi,
html5 would not solve the problem alone. I guess we need a transcript of the prezi -> texts in the order of path. You know in a PPT the transcript is a simple question.Slide by slide and text from top to the bottom. But how can we do this in prezi?

Bummer. No html5. Prezi is beautiful thinking. It would look so in an iPad. Bummer. Deep sigh.

ooh html5 version, from concept to presentation? or javascript version? flash is such a wild hog with memory, I prefer to use something open source, even though authoring or hosting may cost, so js or h5 would be a dearly loved selling point, go on, you know you can and still make $. It would knock em all dead!

Yeah, a lot of folks in my PLN no longer look at my presentations because "they won't work on their iPads" ... it would be nice if there was a production option for this, although I'm not sure I want to feed this latest frenzy.

iPad version is insufficient. Then you need to ask people to download the iPad app to view. That is very inconvenient. The people on this board are 100% correct - the success of your company requires that people can view the presentations in HTML5. PLEASE listen to your customers here.

We would use Prezi in an instant if presentations weren't only in Flash. Unfortunately, the inability to use iOS devices simply kills it for us.

I had a paid Prezi account last year (http://prezi.com/s-m8mcu1ed51/view/) but stopped using it because I could not show my presentation on the iPad.

I know Flash will run on Android devices if they have enough horsepower, but the iPad and iPhone are very popular, and almost none of my clients use Android devices. Even if they did, HTML5 would work on both, while Flash only works on desktops and very powerful mobile devices.

Flash can be forced to mimic some of the accessibility and SEO friendliness of HTML (with extra work) but why be trapped inside an uneditable Flash movie when you could have the code laid out right there for you in HTML5?

I understand if that is not where Prezi wants to go, but with all the demand for an HTML5 version, someone will go there, and people will pay for it.

I know I will!

What a brilliant idea. Didn't even occur to me that my iPod can't view it and I'm frustrated now I've realised.

HTML5 should be considered not just because it works well with the iPad, but as a standard should work well across a variety of platforms without worrying about Flash performance.

A port now may be so much easier than having to port later...

Device specific solutions don't meet the needs of anyone looking to share content with the public. Get rid of flash. It's the only solution.

I hate apple but I think HTML5 would make it more efficient with loading of media, which would be very important with large media.

maybe an autodetect feature? as in when you open a prezi to edit, it detects if your browser is standards-compliant to html5?

The question is pretty simple. Prezi must be available in HTML5 or soon alternatives like Sozi (not as simple as Prezi though yet) will take over. I can't understand why you keep developing it in Flash. I used to create many presentations with Prezi (about 2 years ago) but as soon as I definitely switched to GNU/Linux I've been unable to use it due to poor Flash performance on this system. So I second this request: make Prezi HTML5 compatible. Everyone knows it can be done (it's enough to view the Firefox HTML5 showcase to understand it is) and if you think you might have some troubles please post here the reasons. We (Flash "un"supporters) don't just criticize! But you should be honest and tell us if you keep developing in Flash because of many problems you would have with HTML5 or because other reasons. Thanks in advance.

Cheers.

In my opinion Flash is and will stay a great platform. With AIR 2.6 it is supporting iOS (iPhone and iPad), as well as Android and very soon more upcoming mobile OSs. So I hope to see an iOS and an Android App very soon! But the real big advantage of Flash over HTML5 is, that it is actualy working on almost any actually used browser (IE6, IE7, IE8, Firefox, Safari, Chrome, ...). Maybe not on GNU/Linux. But I don't think that a stagnating market share of 1% for GNU/Linux is a problem of Prezi or Flash.

Not so fast. GNU/Linux share is growing, Android has Linux kernel, iOS is UNIX-like, most of best performing computers use Linux.
In fact Linux is the best option of study for any new guy entering in IT. Is the one with larger range of applications.

just think about it! why should W3C support a single community in HTML5. thats not realistic at all! maybe they will support a new API but then the whole thing has to be translated from Flash to the new API.

nice idea but pretty unrealisitc

You don't have to use Prezi. Just use impress.js. http://bartaz.github.com/impress.js/

As of recently, Adobe has announced they will only release flash for Linux on Chrome. This is a HUGE problem. many people simply do not have the computing power to run Chrome while running other programs, which many people do have to run for productivity. Also, html5 would smooth out such things as copy & paste. And yes, while it is a lot of work, and Internet Explorer (meh) does not support it, it would make it run a lot smoother, and it would be easier to implement customization. We can already see how much more effiecient html5 has already been for Youtube.

Not to toot my own horn, but yesterday I made Awwation, an 'HTML5' Prezi-like app yesterday: Link

Presentations are SVG documents and animated using Javascript.
The editor is very unpolished since I have a lot of schoolwork to do and not enough time. :P
Presentations can be viewed out of the box in any browser, but the editor works best only in chrome.

Some notes (since this topic is about technology, may go into technical details!):

HTML5 prezis would be good for:

1. Accessibility - in the sense that stuff like chrome's inbuilt translator can translate content in the presentation on-the-fly just like anything else in the webpage. And other things.

2. Event handling - I don't know about flash but animations done by javascript have the advantage that events can be thrown during points in the animation timeline. This means that a transcript/description/summary can be displayed beside the presentation and this content can change depending on the time frame. Third-party developers can think of other wonderful things if the flash/webpage barrier is broken. Oh, and one could implement a progressbar! :P

3. Embedding in webpages - This is obvious, and obviously good for iOS devices so that you don't have to open a whole app for viewing some content.

4. Flash really is dying - Yes, it's not there on iOS devices, but now for Linux users (like me), it is only going to be available on Chrome. Sad. :(

Why Prezi still uses flash (my thoughts):

1. Technology - Current browser implementations of standards are sadly still inconsistent across browsers. SVG is a natural choice for prezi-like presentations, but the rendering tends to differ. For example, in Awwation, you can see that the fonts look different across different browsers. Even when you ignore that, it's just not 'fast-enough' yet.

2. Lack of suitable libraries - SVG is what one would pick for creating zooming vector presentations, but it's not fast enough. The HTML5 canvas is a like a 'bitmap buffer' and super super fast, but it cannot handle vector graphics easily because the API is too 'low-level' and you don't get a DOM like SVG. There are some projects like fabric.js that try to provide a DOM-like structure on top of Canvas, but such projects are not 'there yet'. :)

So that's why Prezi still insists on going with Flash. It just works., and is consistent.
But I think it is a good idea to start working on it now. :)

Hi Aditya, Great Job!. As a worried prezi lover (and advanced user), I expect that Prezi company hire you to help them to develop the new version of of the tool without flash needed.

I would be very pleased about a HTML5-based Prezi, too. Just right now I am using prezi to prepare a HTML5 talk presentation. It would be great if i could say: "... this presentation is done using HMTL5 technology ... and prezi".
