Each videographer has a signature shot in each video and in their arsenal. Here in New York, one of the ones I see frequently is a wide shot of a couple in Grand Central station with the three windows above them and the information booth with the clock on top behind them. I even shot the same thing myself. But how distinct can a signature be when I can name the very shot and take it on any day of the week? It's a nice shot, but I'd suggest looking for something a little different to couples out there looking for a videographer. Most people will recognize composition and special effects (for better or worse). I'd suggest watching for emotional connection. Do you know what the bride and groom are like at the end of the video? Do you know how they felt about the moments and their guests? Did they think about different things during the day? Were they unique as a couple? Were their feelings more significant than the rituals they performed? To me, the shot that defines the wedding video is the one that makes me react most strongly. It's not the most impressive shot - it's the most insightful. Personally, my favorite moments are the glances and gestures. They always tell more than Grand Central Station will.
