How to enable HTML5 on youtube
What is Flash?
Flash is a group of technologies for running applications on the Word Wide Web. 95% of Internet-enabled desktop computers have Flash installed, and it's used extensively by many popular websites including Facebook and YouTube. "Flash" is not really one thing, but a system that comprises several components:
- An application file format (either .flv or .swf)
- A web browser plug-in
- A Flash media server
A point of additional confusion is that terms which appear to be a generic descriptive name, like "Flash Plug-in" or "Flash Media Server", also refer to specific product owned and trademarked by Adobe.
What's wrong with Flash?
- It's not an Open Standard
- It requires propriatery Software
- It causes vendor lock-in
- It's insecure
- It threatens privacy
An Open alternative
HTML 5 is a powerful new Open Standard that can be used to replace many instances of Adobe Flash. It comprises a family of technologies, including standards for video and audio, and advanced 2D and 3D graphics. Even before HTML 5 was finalised, in 2011 34 of the world's top 100 Web sites were using it. Youtube are one of these sites - but, for now, you need to tell them you want to take part.
How can I use html5 playback on Youtube?
It's going to take a few years for HTML5 to replace Flash completeley, but you don't need to wait so long to get involved. The video documents one way to use HTML5 on Youtube - here is a step by step guide showing the same thing.
- Open your browser. In this instance we used Firefox, as this seemed to provide the best outcome.
- Go to youtube.com - at the moment, all of the videos will be played using flash.
- Go to youtube.com/html5 and click to "join the html5 trial"
- Thats it, Your in! If you now search for and play one of your favorite videos, it may well be playing in html5. To check, right click on the video and see if html5 is mentioned.
- Unfortunatly not all videos are HTML5 ready, these should simply default back to flash, so you can still watch them. In these instances, when you right click on the video, adobe/flash will be mentioned.
- You need to repeat this process for each computer, and even each browser. As HTML5 inclusion is determined using cookies, you will need to rejoin the trial if you clear all your cookies too.
- ... and if you make a video, render it in webm (vp8, vorbis, matroska)
