Patents

The present invention concerns a clapper device and method for synchronizing the auditory and visual elements in motion picture film production. The device has a standard clapper, a means of receiving timecode from an audio recorder (by wireless transmission or by cable or by some other means), a visual display for indicating a machine readable code indicating the stage of the filming process, onboard processing and storage, and a data entry means. The timecode information and machine code displayed corresponding to the point of time when the clapper is closed are used to synchronize the auditory and visual elements after digitization of the same.

Claims

1. A clapper board for synchronizing film with audio, comprising:

(a) a body;
(b) operable sound producing means, attached to the body and adapted to present a simultaneous physical synchronizing video indication and an electrical synchronizing indication of when the said means is operated;
(c) a receiver in the body for receiving a timecode transmitted from an audio recorder;
(d) a processor connected to the sound producing means for receiving the electrical synchronizing indication from the sound producing means and to the receiver for receiving the plurality of audio timecodes from the receiver, the processor adapted to send a synchronizing audio timecode associated with the moment when the electrical synchronizing indication is received; and
(e) removable data storage coupled to the processor,
wherein the operable sound means includes a display and the synchronizing video indication is a machine readable code presented on a display in the body.

2. The board of claim 1 wherein the data storage containing the synchronizing time code is read by a code reader.

3. A clapper board for synchronizing film with audio comprising:

(a) a body;
(b) a display embedded in one side of the body;
(c) a marker board embedded in a further side of the body;
(d) an alphanumeric keyboard in the body for entering film information for presentation on the display;
(e) a clapper hingeably attached to the body and adapted to present a synchronizing video indication by the display and an electrical synchronizing indication by contact with a micro contact in the body when the clapper is operated;
(f) a receiver in the body for receiving a timecode transmitted from an audio recorder;
(g) a processor connected to the sound producing means for receiving the electrical indication from the sound producing means and to the receiver for receiving the timecode from the receiver, the processor adapted to send a synchronizing audio timecode associated with the moment when the electrical indication is received;
(h) removable data storage coupled to the processor for storing the synchronizing audio timecode and the film information; and
(i) means for accessing the synchronizing audio timecode and the film information in the data storage.
