The developers are working on delivering our new video section for the site this week and I'm pretty excited about getting that up and running asap. We're looking out for any out-takes/bloopers as well as any interesting stuff that just doesn't manage to make the final edit for TV, so the section should be well worth a look once we've managed to get hold of all the clips we're looking for. We'll put our broadcast promos there and anything good that we can get the rights for.
We'll also be looking for User-Generated content so if you've got any local arts-related event to promote or you want to do a review of one of our programmes, a new film or a performance/exhibition that you've been to, then film it on your mobile or camera and stick it up on Sky Cast - we'll be pulling our UG content from there.
Just post up a comment here and let us know what the link is - we'll include it on the Sky Arts video section.
