: Early hand-cranked cameras suffered from significant frame jitter and erratic frame rates (often fluctuating between 14 to 18 frames per second). Frame-interpolation algorithms stabilize the motion and smoothly bring the footage up to modern viewing standards.

The phrase "1080p 40 Vids" suggests modern digital processing, as the original technology of the time had significant limitations: Stills vs. Video:
