A video playing device includes a TV encoding circuit, a pre-setting circuit, and a video processing circuit. The TV encoding circuit encodes a first picture and generates a VSYNC signal. The pre-setting circuit is electrically connected with the TV encoding circuit, and receives the VSYNC signal to set a pre-setting signal. The pre-setting signal is enabled before the TV encoding circuit encodes a second picture. The video processing circuit is electrically connected with the pre-setting circuit, and receives the pre-setting signal to execute a video setting process for setting the video playing device to play the second picture. The video setting process is completed before the second picture is encoded. The pre-setting signal is adjustable such that the video setting process is completed before the second picture is played.
