The generated frame is blurrier than the original frame

I tested 8x interpolation using IFRNet_GoPro.pth and found that although the generated frames have good coherence, the generated frames are blurrier than the original frames. Why is this?

Note that our 8x frame interpolation model IFRNet_GoPro.pth is trained from scratch on a relatively small GoPro dataset, which may generate undesirable results. It is better to train 8x frame interpolation model on the Vimeo90k Septuplet dataset. We will provide improved 8x frame interpolation checkpoints later.
