Patterson–Gimlin 16mm Film
A provenance-first evidence record separating what the film is from what analysts infer it depicts.
The film is evidence of a filmed subject—not automatically of its identity.
The existence of the film is undisputed. The core evidentiary dispute is what physical subject produced the images and how much reliable measurement can be extracted from surviving copies.

Image integrity
Munns & Meldrum argue examined copies show no evidence of deceptive splicing of the camera original before copying and retain analyzable detail.
Surface anatomy
Munns & Meldrum separately argue some visible folds and contours are compatible with biological tissue rather than necessary costume artifacts.
Frame rate
The exact camera speed remains important because gait speed and several measurements depend on it. Archive version 4.1 keeps this unresolved.
Copy generation
Different public versions are not interchangeable. Enhancement, stabilization and generation loss can alter apparent detail.
It does not label visible shapes as muscles, breasts, seams, zippers, facial structures or anatomical landmarks unless a specific analyst/source makes that claim and the claim is attributed accordingly.
