YouTube now supports higher quality videos (finally!). The new format brings better resolution and quality of playback.
To embed high quality YouTube video you need to append &ap=%2526fmt%3D18 to your embed string. Of course if you use WordPress, you can use Smart YouTube plugin which will do this automatically for you, among other cool things.
Watch the difference in example below. First is the low quality version, standard size 425x344.
Now this is a high quality version in 480x360. Not only the resolution is better but quality too. Smart YouTube supports different sizes for normal an HQ videos.
The video is about a guy called Matt, a computer game developer (like me) who decided to travel the world and record the “Matt’s dance” in every crazy place (unlike me).

You could just use this form:

I use that plugin all the time on my other websites - smart youtube is really good.
What about integrating it into tiny editor?

Hi!
Does your plugin only work with InternetExplorer? I’m using the latest version of Firefox and no videos are shown in your post!

That’s a really huge different. Do you meant that by using Smart Youtube, it will automatically change to High Quality video?
