Believe it or not, we do not do this to make you look bad, or to throw your words out of context. Making tv is a pretty complex business, with many, many, technical and creative steps you never see when you are at home watching the set. Decisions get made all the way down the line. While I'm producing your interview, either in the studio, or out in the field, I'll be timing things, and paying close attention to everything you say. If at all possible, I'll catch glitches at that stage, and work with you to redo a section if necessary.
Tv is a visual medium.
You can take great footage, with scientific content on the slim side, and still make a great story, but the reverse is never true. If you hold the key to life itself, but have no footage to back you up, you will not be a great story for tv. So, if you want your work shown on tv, it might be worthwhile to spend a little time trying to 'think in pictures' about your research. Also, record important developments as your research progresses. Stills can be useful, but are obviously a second choice.
