You might want to start considering how the video will link to the print products.

Don't forget - you will need to produce a magazine advert and a digi-pak linked to the album your single is taken from. Now that you are getting close to (or indeed have started) shooting, you might want to kill two birds with one stone and gather appropriate material for your print products (this is what Kathryn did last year). Make sure you take a digital stills camera with you on your shoots to record behind-the-scenes info as well as possibly taking pictures you might use in the final pieces.
