Abstract
A lighting system includes at least a first light source and a second light source. The system also includes a camera system configured to capture sequential video frames under multiple lighting conditions. The system includes a synchronization system that is configured to activate the first light source during the last millisecond of a first frame and the second light source during the first millisecond of a subsequent frame. Applications include modern cinematography workflows requiring efficient lighting design and superior scene capture under varying illumination. Various other methods, systems, and computer-readable media are also disclosed.

A system for lighting in video production, comprising:
- a lighting system including at least a first light source and a second light source, wherein the first light source and the second light source are capable of being selectively turned on for a duration of one millisecond or less;
- a camera system for capturing video in sequential frames including a first frame and a second frame temporally adjacent to and after the first frame;
- and
- a synchronization system that synchronizes the first light source to activate during a last millisecond of the first frame and the second light source to activate during a first millisecond of the second frame, wherein the first light source and the second light source are both deactivated during remaining times of the first frame and of the second frame.
A method for lighting in video production, the method comprising:
- capturing a sequence of video frames of a scene using a global shutter camera;
- emitting a first light pulse from one or more computer-controlled light sources, the first light pulse having a pulse duration of one millisecond or less and occurring at a terminal portion of a first frame exposure;
- and
- emitting a second light pulse from the one or more computer-controlled light sources, the second light pulse having a pulse duration of one millisecond or less and occurring at an initial portion of a second frame exposure immediately following the first frame exposure, the first and second light pulses being synchronized to occur within one millisecond of each other.
A method for forming a system for video production, comprising:
- operatively coupling, to a light driver, at least one first light source and at least one second light source;
- operatively coupling, to the light driver, a global shutter camera for capturing video in frame sequences each including a first frame and a second frame;
- and
- synchronizing the global shutter camera and the light driver to cause the first light source to emit a first light pulse during a last millisecond of the first frame of each frame sequence and to cause the second light source to emit a second light pulse during a first millisecond of the second frame of each frame sequence.
