House of El: The 4K Is a Lie
We downloaded the 720p, 1080p, 1440p and 2160p renditions of a House of El: AI video, measured the spectrum, round-tripped every frame through 1080p, and compared it to native 4K references. The 4K is an upscale. The person behind it is real. The “am I AI?” panic is a business model.
Spectral fingerprint
Radial FFT of the luma plane. Native 4K keeps declining past 0.25 cycles/px; an upscale hits a wall and becomes a noise floor.
1080p round-trip
Downscale the 4K frame to 1080p and back. If it reconstructs at 50+ dB, the 4K had no information above 1080p.
Native calibration
Encode two native 4K references at the same 6 Mbps with VP9 and run the identical test. Native detail loses much more.
Archive & records
Web Archive snapshots, SDU thesis records, Bank of England working papers, public LinkedIn education/experience.
What this is
A technical and archival case file. The 4K measurement is reproducible from public YouTube files; the identity verification is based on public records (PhD thesis, BoE working papers, a 2019 local-news profile).
What this is not
Not a doxx, not a legal finding, not a claim that a private individual must reveal her identity. Private contact details, addresses, family information and private social accounts are not published. Third-party images are used for criticism/analysis; rights remain with their owners. Corrections: open an issue on GitHub.
