CLOSED-CAPTION DELIVERY CONTROL
Choose Caption Master Access Modes
Map No Write, No Delete and No Access to each caption editor, reviewer and Windows account.

01 / CONTEXT
Define the control decision
The strongest restriction is not automatically the safest. Reviewers may need read access while the final subtitle master must resist writing or deletion. Test each mode with the actual caption application, export workflow and service accounts.
Map No Write, No Delete and No Access to each caption editor, reviewer and Windows account.
02 / PROCEDURE
Run the control sequence
- 01
List every person and process that reads or writes the master.
- 02
Test No Write against the supported caption application.
- 03
Test No Delete without assuming it prevents copying or renaming.
- 04
Use No Access only when the workflow does not require reading.
- 05
Record the selected mode, exception and recovery owner.
03 / EVIDENCE
Preserve proof without personal data
A defensible control record identifies the caption owner, video title, language, subtitle format, frame rate, authoritative path, permitted accounts, restriction mode, version ID, accessibility-review date, checksum evidence, recovery owner and next review date. It should not contain unreleased media, personal data, credentials or confidential production notes. Use fictional media and non-identifying speaker labels during every technical test.
Recheck the arrangement after changes to Windows, caption software, accessibility tooling, localization workflow, storage, Folder Protect, permissions, service accounts or production roles. Confirm both usability and recovery: an authorized editor should read the final subtitle master, an unauthorized account should not alter it, and the recovery owner should restore a separately held copy without depending on the protected folder. Preserve unexpected behavior before changing controls.
Keep the claim narrow. Local restrictions may reduce accidental writing, deletion or access on a tested Windows path, but they do not encrypt data, establish caption accuracy, timing, synchronization, speaker identification, readability, accessibility conformance, localization quality or delivery acceptance, administer identities, provide version history or replace backup. Escalate those requirements to the platform and accountable accessibility owner designed to meet them.
Ask a second editor to follow the written procedure without verbal help. Record whether that person can identify the final master, create a working copy, recognize the version stamp, interpret denied access and find the recovery owner. This usability check reveals ambiguous paths, hidden service-account dependencies and undocumented knowledge before a caption application, delivery platform, storage or staff change. Correct the procedure, repeat the test with fictional media and retain only minimal evidence.
04 / BOUNDARY
State what the control cannot prove
Folder Protect is not encryption, caption validation, accessibility approval, identity governance, delivery authorization or proof that another copy does not exist.
Validate the exact Windows account, caption application, caption workflow, storage path and current product release. If encryption, caption approval, accessibility review, immutable history, identity governance or regulated retention are required, select systems designed for those jobs rather than broadening a desktop restriction claim.
