raising "scale" number does not make the video smoother

[mikebilly]

it was stated that:

If you generate disordered pattern on your videos, try set --scale=2.0. This parameter control the process resolution for optical flow model

on https://github.com/hzwer/arXiv2020-RIFE, but I have done two tests and found that: exp=4, default scale on model 4.0 is much smoother and has less distortion than exp=4, scale=4.0 on model 2.4. I thought the higher the scale is the smoother the video will become, but scale=4.0 created a less smooth video than default scale (scale=1.0)

I thought the higher the scale is the smoother the video will become

Well, you thought wrong.

So what does scale do? How can I increase the quality of the output?, (smoothness, ... )

better to use VGG loss to retrain the model, lap loss will decrease the visual quality of RIFE
