A cue with no positive duration has no viewing interval.
Reproduce the condition
The WebVTT sample below is a small synthetic file. It carries no active media source or account data.
WEBVTT
00:00:02.000 --> 00:00:02.000
Example captionWhat the local check found
| Expected signal | Observed signal |
|---|---|
| Cue end is at or before its start | Cue end is at or before its start |
What to do next
Compare with the spoken line and restore the actual cue end. Avoid moving every cue to compensate for one malformed interval.
What to share if the problem continues
- The exact parser result and version of the importer or player.
- A minimal redacted sample with dates, IDs or segment names retained as needed.
- The output after checking the source export separately from the viewer app.
