Anime sometimes has 8fps and 12fps in same video

n_forward 2 makes video more blurriness

scene detection can be used to auto identify duplicate frames then skip them instead of using n_forward (IDK how to do this)

I did manually removed duplicate frames from video and got less blurriness as a result

The removal of duplicate frames based on recognition cannot guarantee 100% accuracy in identifying duplicate frames. It may result in under-deletion or over-deletion. However, this method avoids the need for recognition and achieves 100% accuracy by directly leveraging the principles of anime design.

The difficulty of manual recognition and machine-based automatic recognition is different. Moreover, when you manually remove duplicate frames, it's inevitable that you will lose background motion information.

If you want to remove duplicate frames using a threshold-based recognition method and apply GMFSS, you can use frame interpolation software like SVFI for similar purposes.
