To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	function b2a(a) {
	var c, d, e, f, g, h, i, j, o, b = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=", k = 0, l = 0, m = "", n = [];
	if (!a) return a;
	do c = a.charCodeAt(k++), d = a.charCodeAt(k++), e = a.charCodeAt(k++), j = c << 16 \| d << 8 \| e,
	f = 63 & j >> 18, g = 63 & j >> 12, h = 63 & j >> 6, i = 63 & j, n[l++] = b.charAt(f) + b.charAt(g) + b.charAt(h) + b.charAt(i); while (k < a.length);
	return m = n.join(""), o = a.length % 3, (o ? m.slice(0, o - 3) :m) + "===".slice(o \|\| 3);
	}

	function a2b(a) {
	var b, c, d, e = {}, f = 0, g = 0, h = "", i = String.fromCharCode, j = a.length;
