When using the slimming function, Tik Tok will recognize the face and body contours of the characters in the video, and fine-tune the body contours to make the characters look slimmer and slimmer. However, because the position and angle of the characters moving in the video are not fixed, the slimming function may affect the shape of the background. When optimizing the shape, some details in the background may be stretched or distorted, which makes the background look deformed or distorted.

The optimization effect of Tik Tok slimming function is limited, but when using slimming function, it is necessary to pay attention to whether the background is deformed, so as not to affect the quality and beauty of the video.
