Impossible because dunk Master is an animation, its frame rate is fixed, set after can not be changed.
120 frame rate refers to the number of screen refreshes per second, for animation, generally 30 frames\/second or 60 frames\/second can present a smooth picture. Moreover, to achieve a stable 120 frame rate requires extremely high graphics card performance and processor performance, which is almost impossible on ordinary computers.
Not all movies\/TV series need a high frame rate to present a good picture effect, high frame rate can make the picture more smooth, but at the same time, it also increases the production cost and hardware requirements. Most movies and TV shows are still produced at the traditional 24 or 30 frame\/second frame rate.
