The encoder version and options are ordinary technical metadata. They do not independently prove that a recording has never been edited.

The original filesystem creation time was 2026-11-03 20:50:40.970 UTC and the last-write time was 20:56:54 UTC. These are filesystem observations, not embedded trusted timestamps; copying or uploading a file can change its filesystem dates without changing its bytes.

Frame review shows the test account's phone number and the guest's `C:\Users\demo` path in the picture. A container-metadata inspection does not remove information visible in the recorded screen. The metadata check is not an exhaustive frame-by-frame privacy review.

SHA-256:

The original was not stripped, re-encoded or replaced. If a redacted version is later required, it should be supplied as a separately identified derivative.
