With FrameSync, the Vortex8 can be triggered from an external source, such as a sync generator (e.g. Ambient Lockit ACN-CL), or the genlock output of a cinema camera, to ensure that it is synchronised with the camera shutter. This is especially useful when using effects such as strobe, where a lack of synchronisation between the camera and the lights can cause issues like frame tearing and flash banding. This feature alleviates the problem that most digital CMOS cameras can have with any flashing or strobing light source. It can also be used for frame-accurate strobing for advanced special effects, for frame rates up to 5,000fps.
