Just an FYI.

I've been promoting the use of fragments for (binary) video file.  (Not
here... but privately and on one public mailing list.)

For example...


Also, I've suggested (privately and on one public mailing list) the use of
fragments on video files for "pointing to" clips.  (I.e., "pointing to"
intervals of the video.)

For example...


(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".)

(This notation was inspired by the "xpointer" fragments.)

See ya
