Index into video (series)

[John Graves]

Just worked through the 9 videos on Boa Constructor and wanted to
refer back to a particular section. Could there be an index made for
this (or other) series? I've seen something at www.ted.com where
parts of a talk are identified if you move your mouse over the
timeline. For example: http://www.ted.com/talks/lang/eng/helen_fisher_studies_the_brain_in_love.html

See the file timeline.jpg in the discussion Files where I've put a
screenshot to show what I'm talking about.

The kind of index below would be helpful, but I was hoping for
something more granular. Like a table of contents with subsections.
And with links INTO the video (if possible???).

1 - Overview of Boa Constructor and How to Get It
2 - Feature Tour of Boa Constructor and "Hello, World!"
3 - The Palette in Boa Constructor
4 - The Inspector in Boa Constructor
5 - The Frame Designer in Boa Constructor
6 - The Editor in Boa Constructor, Part I
7 - The Editor in Boa Constructor, Part II
8 - Using Sizers in Boa Constructor
9 - 12 Tips, 6 'bugs' and some resources for Boa Constructor

(And, yes, I know this is available on http://showmedo.com/videos/series?name=wKQrywla5
with comments)

hi john,

it's been an idea for a while, very much at the back of my mind. If we didn't have a bit of a manpower problem around here I would put someone on it. The idea of being able to 'bookmark' videos is very feasible - I have it working in prototype. And I too was struck by the TED example - very cool. All depends on having a budget and by association time. Which depends on getting the club in shape... etc..

but cheers for the feedback - it's great to get it and does go on the (long and getting longer) list.
