Description
The clip from Your Name. shows that the vertical bars are distorted by the horizontally moving train.
This is witnessed on v4.6 and v4.4. Using Flowframes with v1.8 and v3.1, only some frames completely lose the bars, and there are just minor distortions.


This effect can also be seen with textured horizonal line against vertical movement.

Research direction
Start by reproducing the attached Your Name clip and the textured horizontal-line example with Practical-RIFE v4.6 and v4.4, then compare them with Flowframes v1.8 and v3.1. Done means the vertical bars or textured lines remain intact during opposing motion, with the relevant reproduction conditions and affected version documented.
