The results are shaking

Hi author, thanks for your impressive work! I have a question about my own video. After interpolating and gathering all frames into a video, I find that the video shakes severely. Specifically, it seems like the interpolated frames are cropped using a larger box from the padded output and then scaled down to align the resolution.
Besides, if I use some videos with high FPS, the shaking is lighter.
