Aside from dealing with IE 8 and earlier, the major issue with embedding HTML5 audio and video in web pages is the variety of formats / codecs that must be supported. Conversion between these can be a little tricky if you don’t have the right tools to hand; fortunately, all the applications you need are free.
The first and primary rule before doing any format conversion of any media file – image, audio, or video – is to use the best quality version of the media file as the source from which compressed versions will be derived. (See the article on video workflow tips for more information on this process).
