Context

Two weeks ago I made a presentation at an Open Content workshop in Como. I promised particpants I would post the slides and audio of the presentation. I made a first version using the audio of my presentation- but at 47 minutes it did not make for compelling viewing. I made a second version  - this time redoing the audio whilst following the slides. This came in at about 19 minutes which still seemd too long. I scripted the audio for this version and then edited the slides following the audio. This version seems to me about the right length - though perhaps it could be even shorter.

I intend to produce a series of short videos like this and would be  interested in feedback. it is difficult to guage how long these things should be. Making them even shorter is quite attractive but it means cutting down on the breadth and depth of the content.

For future videos, I will try to produce a full presentation 'pack', including written materials and references.

Technical notes

This is produced using Apple iPhoto, i Movie and GarageBand applications. The vdieo was exported to Quicktime using the preset web movie settings. I am not happy with the quality of the lettering. Any advice on how to get better quality would be very welcome. I suspect the answer may be to produce 2 versions - one a relatively small version like this for downloads and a second, MP4 (?) version which will be too big to realistically download but will provide better streaming quality.
