I have finished filming the first GNOME 3 launch video. In the coming days I'll post the video for review to the marketing-list so that I can get some feedback. And then, it will go on to the translators for subtitle translation (a11y and i18n are important to the GNOME community!) And then, with a little luck, the video should be up somewhere public shortly thereafter with all the "source" files so that the videos can be re-mixed and branded by downstream distros. But that's not what this post is about.
I hope that you all agree that it would be pretty lame if I'm the only guy in all the launch videos so I hope we can get good diversity of speakers in our videos representing the different nationalities and different ablednesses of our community. From my own experiences, I updated some "best practices" on the HOWTO here: http://live.gnome.org/GnomeMarketing/Gnome3In30Seconds/HOWTO. I did it all for less than $150. (I only had to buy the work lamps from a hardware store.) However, if you're a student at a university or if you ask around, you may be able to do this with no budget at all.
I filmed the first idea on this page: http://live.gnome.org/GnomeMarketing/Gnome3In30Seconds so there's plenty more ideas.
If you are interested, please join the marketing-list and coordinate there. Looking forward to seeing the creativity of the GNOME community!
