Our rapid product and customer development pointed to an obvious twist on the original idea - instead of chopping up old videos, we should build a camera app optimised for filming sports clips, that lets users publish right from their phones. We could then ask the users to add the special tags at the point of publishing, which would enable us (and them) to concatenate different clips together based on tags to create new edits around tricks, spots, teams, people and so on as per the original idea. This also solved a bunch of technical issues around video formats, sound and quality.
We started cranking out the new app as quickly as possible. It was about three weeks since we'd started work. We planned to get an alpha release / MVP out the door within four weeks, giving us another six weeks to get a more polished beta done.
