Hi, the picture quality is not really good (in my use case). I use the program to upscale a fullhd video. In the output you can see very clearly that the frames are decomposed into subframes, upscaled individually and then stiched back together.  There is a visible border between the subframes. It almost  looks like a grid has been put over the video. Is there a setting to improve this? So far I have tested RealESRGANx4_70% and RealESR_Gx4_70%
