Things to notice in this one shot from "Spider-Man: Into the Spider-Verse" (2018):
• Both Miles and Peter are animated on 2's (12 poses/sec), while the scene was rendered on 1's (24 frames/sec). So even though they're frozen for two frames, they are moving within the frame.
• They are on animated 2's, but offset from each other.

Scenes in the film were not rendered with traditional motion blur--nothing within the frame is smeared (just like comics). To simulate smoother motion in this shot, pieces of echoey geometry appear trailing Peter's screen left arm on certain frames, filling in "gaps".

A closer, slower look. Check out Miles' hand as he releases the bagel, for another way artists simulated motion blur without rendering motion blur.
A fun thing to look for in "Spider-Verse" are moments where a character shifts from 2's to 1's within a single shot. For extra credit: look for shots where parts of a character's body are animated on 2's and other parts of the body are on 1's!
