How do you plan to have users enter the info? Through the Flash player, through some kinda Ajax form, through a form in a frame or just a static form? Also, would the tags be predefined by you (eg. genres like the ID3 tag genres) or would people be able to add their own tags? The way I'd do it would be to let the users enter the info through an Ajax form below the video, with suggestions popping up as they type. Then save it in a separate table (I assume all your vids are in their own table) with a link table between the vids table and the tags table (M2M relationship). This means that if the tag is already in there and linked to one vid, you don't replicate it for a second vid. It's also very easy to do lookups of similar items. I'd also add a weighting to the tags in the links table, maybe with the more people that add a specific tag, the more weight that tag gets.
