Software-camera & loop indicators

These are indicators, not proof of a virtual camera or prerecorded video. Extensions can hide or spoof evidence; legitimate browser software, a still scene, and repeated movement can produce similar results.

Longest loop to check

Each test observes at least three cycles of the longest selected loop. Keep this tab visible. A still scene is inconclusive; loops longer than the selected range are not assessed. Stop cancels the test and retains the partial sample.

Page monitoring is active. Start a camera for track and frame checks.

Compare two exported reports

Choose two JSON files. Browser-generated IDs and live scene settings are separated from meaningful transport differences.
