Moving Performances
Performing starts with movement and smooth moves on camera that demand some tricks of the trade.
When normally graceful people get on-camera, they can turn into zombies or klutzes or puppets left dangling. Why is that? Sometimes it's stage fright, but more often the problem lies in the technical demands of the medium. Technical problems are fixable, as we're about to show you; so let's see how to block subject movement and help performers manage their bodies on camera. For convenience in this discussion, subjects (performers) are all "she," and any shooting area is a "set," whether on a stage or on location.
Blocking means setting and rehearsing subjects' movements on camera. All subject movement should be staged strictly for the way it appears on the screen, no matter whether it looks natural in the real world (see the adjacent sidebar). For instance, if a subject enters from the side and walks up to the camcorder, her real-world path would typically be a straight line. When blocking her for the screen, however, it looks quite natural (and often more attractive) to make her path a smooth arc.
Now suppose she has "business" (rehearsed activity) to perform before ending up in front of the camera. For example, she crosses to the ficus plant in the rear and waters it, then moves to a side table, puts down the watering can, and finally takes her position in front of the camera. Each of these three positions has been carefully lit and each requires a slightly different camera focus; so it's essential that she stop on exactly the right "mark" (spot) at each location
The first two marks are easy because the subject can memorize her position vis-a-vis the plant and the table. To hit her third spot exactly, she'll need an actual mark - usually chalk or tape - on the floor.
There are three ways she can "hit her mark," as it's called. She can track the mark in her peripheral vision as she approaches it. She can feel the heat and brightness of the key light focused on her stopping position (professionals get very good at this), or she can actually look at the mark - a method that works best if she's supposed to gaze contemplatively at the floor. Whichever her method (or combination), you can help her by rehearsing her full movement path thoroughly before shooting.
An ancient director's instruction to actors: "Don't just do something, stand there!" It's hard to stay still and relaxed under the eye of a camera. Subjects stand awkwardly, lose track of their elbows, shift from foot to foot and fidget around unnaturally.
In blocking movements, it helps to end at anchor points: a chair, a lectern - any object that gives subjects a destination instead of an arbitrary stopping point somewhere on a floor.
Wherever they stop, subjects should fall into a relaxed stance: weight on one slightly forward foot, back and shoulders straight but not military. Hands down at the sides get awkward very quickly. Instead, try clasping them lightly together in front of the waist (a very common trick with singers). I prefer to keep my hands with the thumbs and index fingers just lightly touching one another, but that's just a personal preference.
Holding the arms like this tends to keep elbows away from the body. That way, when a subject gestures with them, the whole arm moves instead of just the forearm. A performer windmilling forearms and hands from closely held elbows resembles a twin engine plane. Generally, when you're raising an arm to point at something, the elbow should rise with or just ahead of the hand.
Finally, if a subject must remain in position for a lengthy speech, try switching her to a high stool (e.g., a tall bar stool) and then framing a new angle that conceals the stool. It can make things more relaxed for the performer.
