RIFE with v4.7-4.10 models are said to be optimized for anime:

Here are the methods I tested (VapourSynth):
Automatic+60fps+Animation on Remy and Boo episode converted to 20 fps
Automatic+60fps+Animation on Remy and Boo episode converted to 15 fps
RIFE Nvidia TensorRT 4.6+48fps
RIFE Nvidia TensorRT 4.9+48fps
RIFE Nvidia TensorRT 4.14+48fps
RIFE Nvidia TensorRT 4.14 ensemble+48fps
RIFE Nvidia TensorRT 4.10 ensemble+48fps
RIFE Vulkan 4.4+48 fps
Any configuration above with Movie×y/Movie frame rate×y, where y is the multiplier for the frame rate
It seems like SVP 4 Pro has a hard time on Remy and Boo-style animations, specifically (not just this one title, though). In one case, one character moves one frame, while the next character moves the next frame, so converting the video to a lower fps and then smoothing it is probably the best option as of now. The other case, the background and transitions animate very smoothly, while character animations, don't work as well.
I think the main problem with SVP 4 Pro is that it doesn't smoothen out some animations that have a greater distance between the first and the second frames, such as characters running.
Alva's World, Luo Bao Bei, and Work It Out, Wombats have been tested and the best working one for me is either the Automatic+60fps or the RIFE Nvidia TensorRT configs.
I have attached a sample video for testing purposes (attachments don't seem to work for me in the forums, so it has been uploaded to OneDrive for now)
