It helps scientists understand the "fusion pore" formation, which is the exact moment the virus injects its genetic material into a host cell. 2. Alternative: Computer Science & Data Visualization

There is a separate project titled .

While there are other niche technical interpretations, here are the two most likely contexts: 1. Most Likely: Structural Biology Research

Supplementary Movie 3 (cv3.mp4) typically shows a 3D reconstruction or a "tilt series" of the virus's spike protein interacting with a cell membrane.

The file is likely "Supplementary Movie 3" from the paper "Unveiling the complete spectrum of SARS-CoV-2 fusion stages by in situ cryo-ET" , published in Nature Communications (2025) or similar high-impact journals.
