Subtitle quality control

The system questions itself. Then a human decides.

Undertitle does not treat every AI cue as correct. Uncertainty is marked. House rules are checked. Editors review the exceptions.

Q Review

Quality control is the product, not a plugin.

Generic generators stop at text. Broadcast files fail on timing, overlaps and house-rule drift. Those errors are first-class, not a later department.

The Q layer is how Undertitle stays calm under volume. The model drafts. The rules constrain. The score points. The editor signs.

  • Q Rules. Timing, readability, segmentation and technical specs of the channel.
  • Q Score. Confidence per asset, so review time is not spent equally on every line.
  • Q Approved. Status after a human has kept the final word.

That is control as a brand position: predictable output, auditability, and a person still responsible for air.

Security is a condition, not the pitch

Privacy, governance and compliance have to be true. They should not make the product sound like a policy PDF. The story is still: we cracked the operational problem, and you stayed in control.

What we check

Before the file leaves the building

Subtitle quality control here is the last automatic net before the editorial check — not a claim that machines can air unsupervised.

Overlaps
Stacked cues never pass as probably fine.
Gaps
Unexplained silence in dialogue is a missing sentence.
Reading speed
Dutch that is too fast is rewritten or split.
Shot changes
Cuts are respected so viewers are not reading across a new image.
House-rule breaks
Forbidden shortcuts and spelling variants are flagged against the Q Profile.
Uncertain cues
The system questions itself instead of bluffing.
Export wrapper
The delivery format you asked for is the one you get.
Human gate
Q Approved is a person, not a colour.

Frequently asked questions

What is subtitle quality control in Undertitle?
Automatic checks against your Q Rules — timing, readability, segmentation, terminology — plus a human Q Review on flagged exceptions.
Does a high Q Score mean it can air?
No. Q Score directs attention. Q Approved is the human signature. A green number is not a broadcast decision.
Can we keep our existing QC tools?
Yes. Treat ours as an extra net before your usual pass, not a replacement religion.
What gets flagged?
Overlaps, illegal reading speeds, shot-change drift, house-rule breaks, and cues the model is uncertain about.
Is this the same as a confidence score from a generic model?
No. Scoring is against your Q Profile, not against “sounds like Dutch.”
Who signs Q Approved?
Your editors. You keep the final word.

You keep the final word.

Quality control that points at exceptions. Editors who still sign the file.
