La verdad es que Firefox4 está de lujo, y las demos que ofrece Mozilla son increíbles. De una de ellas he sacado cómo hacer clipping en vídeos usando HTML5 y la posibilidad de incrustar SVG (sólo funciona en Firefox4).

SVG
Vídeo
Javascript
var play = document.getElementById('play');
var pause = document.getElementById('pause');
var video = document.getElementById('video');
play.addEventListener('click', function() {
play.style.display = 'none';
pause.style.display = 'block';
video.play();
}, true);
pause.addEventListener('click', function() {
play.style.display = 'block';
pause.style.display = 'none';
video.pause();
}, true);
video.addEventListener("ended", function() {
play.style.display = 'block';
pause.style.display = 'none';
video.pause();
}, true);El vídeo es el mismo que el de la demo de Mozilla, he puesto el borde semi-transparente para que se vea el clipping como va.
