Some shoots are simple, a single cameraperson gathering footage in a "documentary fashion" under the direction of a client. The specifics of the project (and the budget) will determine what equipment is used to shoot the raw footage.
For efficiency, or sometimes effect, footage is shot handheld. In other cases, the camera is mounted to a tripod for stability and to facilitate simple camera-moves such as pans (side-to-side) and tilts (up-and-down).
Where the shooting space, as well as schedule allows, we can employ a Dolly to perform 'rolling' shots that give a wonderful 'cinematic' look to the footage, employ a Jib, which is a large arm that the camera is mounted on. On rare occasions we have gone so far as to employ a Steadicam. Some corporate clients have asked us to incorporate aerial views, i.e. of their facility, in their video.
In some cases additional light is not required (when speed and efficiency is the key factor) to obtain a good image, today's camera technology allows shooting in most light settings (i.e. offices, shop floors), this is called shooting with "natural light". In other cases, lights are set for each 'scene' to create the best possible image, brighten up low-light areas, or highlight a particular person or product in the frame. In some cases, the cameraperson puts up and sets the lights; in other cases a separate person with or without an assistant. In virtually all cases, these lights are small fixtures (100 watt to 1000 watt) that run off normal electrical supply (wall plugs in any house or office).
In some cases, it is necessary to record dialogue as we shoot, in others we record narration or voice-over later in a studio, in which case we only record 'background sound' as we shoot which may or may not be used later. In a case where only one person is speaking, we would normally use a wired clip-on microphone. In other cases, wireless mics are used; and in still other cases a boom mic is employed to capture voices.
Talent is of course as an important factor. 'Talent' refers to anyone that is appearing on-camera, from professional actors to non-actors, such as a company executive. Good directing is the best assist talent can have, especially non-actors who need assuring and coaching - we specialize in this.
On higher-end productions, there are many tools that can help talent look and speak better, if budget allows. Some examples are the use of a TelePrompter; this is a device that mounts on the camera and displays the words to be read, so that as the talent reads, they are looking directly into the camera lens. Also on higher-end shoots, we often employ a make-up and hairstylist to make the talent look their best.
Some videos can be shot in a matter of hours, others have their shooting time measured in days as the complexity and "look" of each shot is the driving factor.
In most cases, the shots or images are not taken in the order that they will be appearing in the final production, but rather filmed in an order that makes logistical sense. Shots will be reordered later in editing.
Other production's shooting times are determined by the length of events, such as videotaping a sales presentation or an live-event of some type.
