I've just been sent this notice which might be of interest (presumably a European initiative):

Harnessing YouTube for the Arts - posted 02.5.2007

The Culture.Info portal will shortly be adding showcase.culture.info, a portal focusing on clips of performances, exhibitions and venues.

Showcase.culture.info will provide a directory of clips hosted by YouTube and around twenty other similar services from around the world.

It aims to help:
. Prospective audiences, by enabling them to view clips of what they might want to see
. Festivals and venues, by enabling them to view clips of touring performances
. Touring companies, by enabling them to view clips of possible venues
. Organisations seeking partners for joint projects, by enabling them to view clips of the work of potential partners

To date, organisations supporting the service include the Edinburgh
Festival Fringe, LIFT, IFEA Europe (festivals network) and the Voluntary Arts Network. There will be an initial announcement of showcase.culture.info at the MayFair 2 event being held at Tate Modern
on 9-10 May (see www.euclid.info for details) with a launch to follow on 1 June.

In the meantime, Culture.Info is looking for clips to add to its directory. Please email info@culture.info with either of the following:
. Your clip (up to 10MB), preferably as a compressed file
. If you already have a clip on YouTube or a similar service, just send the relevant URL

You should also include some notes about the clip - e.g. title, short description, artform, where your company is from, where you are performing and dates if relevant, etc.
