HTML5 Media Controllers
An HTML5 media controller can synchronize and otherwise coordinate the playback of multiple media elements. For instance, you could use a media controller to overlay a sign language interpretation track over a video track and keep the two in synchronization.
A media controller has the same methods and events as an HTML media element. This means that, for example, when you call the
pause() method on a controller, any media slaved to that controller will be paused; or when a controller receives a
canplaythrough event, all media slaved to that controller can be played through to the end without buffering.
HTML5 Timed Text Tracks
HTML5 timed text tracks enable captions, subtitles, descriptions, and chapters by letting you specify the timing of text that appears with a video element.
CSS filters let you apply pixel effects to any image or web page element with a single line of code. Available filter functions include the following:
Filters can be combined, and changes to the filter property can be animated with CSS transitions or animations. The figures below show an image with various CSS filters applied to it.
Using Scalable Vector Graphics (SVG) filters, you can combine several filter primitive elements and light source elements into a single sophisticated filter, which can then be applied to any SVG element.
