<br><br>For example...<br><br><a href="http://example.com/video.mpeg#smtpe(01:20:39:15)">http://example.com/video.mpeg#smtpe(01:20:39:15)</a><br><br>Also, I've suggested (privately and on one public mailing list) the use of fragments on video files for "pointing to" clips. (

<br>(Note that there are 2 SMTPE time codes there separated with a hypen. So it would be the clip, with in the video, from "01:20:39:15" to "01:28:14:50".)<br><br>(This notation was inspired by the "xpointer" fragments.)
