Thanks, Perrone, for your thoughts, much appreciated.
Just to explain my situation a little, I have done a series of photos (free) for a charitable organisation which is developing a state-of-the-art website. They are using my photos exclusively, take mostly with my D3.
As part of the website, they engaged a video photographer to come up with a clip, The result was totally sub-standard. Hence my original question in this thread. I am agonising over whether I should try to do something I'v never attempted.
