<h2>Synchronization </h2>
<p>A parallel group of clips can be stopped at the same time using the <b>
endsync</b> attribute in the <par> tag.<br />
<br />
<b>endsync="first"</b> stops all the clips in the <par> group when the shortest
clip are finished regardles of any time parameters set for the other clips.<br />
<br />
<b>endsync="last"</b> concludes the <par> group when all clips have finished
playing. This is the default.<br />
<br />
<b>endsync="id(ID)"</b> concludes the <par> group when the clip with the
identified (ID) clip are finished. The ID is referring to the value of the clips
id attribute.</p>
