Now that we have some basic control over individual media let's see how we play them together.
The <seq>
tag is used to define a sequence of media.
..... <seq> <img src="img1.gif" region="reg1" dur="6s" /> <img src="img2.gif" region="reg2" dur="4s" begin="1s" /> </seq> .....
So the setting 1s makes the img2.gif icon appear 1 second after img1.gif.
