Description

Technology Field

[0001] The following embodiments relate to a vehicle-connected filming trailer device for reproducing movement. Background Technology

[0003] Generally, when producing video content such as movies or dramas, equipment was mounted on a moving vehicle to create dynamic horseback riding or motorcycle riding scenes.

[0004] In particular, because real horses pose a constant risk of unpredictable behavior and safety accidents, a method of producing horse dummies to replace them and securing them to vehicle cargo beds for filming is widely used.

[0005] However, conventional filming methods involved arbitrarily modifying the cargo bed of a standard cargo vehicle or attaching unstable extension plates and auxiliary wheels to the rear of the vehicle to accommodate personnel and equipment, which resulted in serious safety issues such as structural fatigue failure or passengers falling out when exposed to road shocks while driving.

[0006] In particular, conventional technologies have limitations in visually realizing the relative sense of speed of dynamic acceleration and deceleration that occurs when a real horse gallops, as they operate horse dummies in a simply fixed state, causing the vehicle's driving speed to match the subject's movement.
