Synthesia on a mark a finished video does not lose
Every other persistence cell in this record is about a mark surviving somebody else's handling. This one is about a mark surviving its own owner, which is the sense of the word a production discovers under deadline. As of 2026-09-22.
| Point | What the record holds |
|---|---|
| What survives | A test-mode mark, on a finished video, against its owner's wishes |
| Read from | A knowledge-base article describing both causes of the mark |
| What it does not settle | Whether the original request can be replayed exactly |
Inclusion rule. One cell of this generator's entry, quoted from the page the entry names. Coverage, commentary and third-hand summaries are not admitted, in either direction. Order. Fixed order: the cell, the page it came off, then the limit on reading it.
1The useful kind of permanence, from the wrong side
A regulator wants marks that persist. A production wants marks it can control. This sentence gives the first and denies the second, and it is the only cell in the record where those two readings point in opposite directions so plainly.
Neither reading is wrong. A notice that a customer can lift off a finished file is a weak notice, and one that cannot be lifted is an expensive mistake when it was applied by accident.
2Re-requesting is not the same as re-exporting
The fix named on the page is a new request with the flag off. That means the asset is produced again rather than repaired, and a generated video produced again is not guaranteed to be the same video.
Where an approved cut exists, that difference is the whole problem. Nothing on the page addresses whether an identical result can be reproduced, and the cell records the gap rather than assuming either answer.
3Why this makes the test flag the condition to watch
A plan can be upgraded and the next render is clean. A test flag leaves an artefact that no purchase reaches, so the cost of the mistake is a render rather than a setting.
That is the strongest practical reason in this record for writing the request parameters into a delivery record. The field costs nothing at the time and is the only thing that will explain the file afterwards.
