FA-78322 / Subtitle cue timing / Member archive

Subtitle conform to an edit cut list: shift accumulation · case 02

Cues after two or more cuts are shifted by only the most recent cut.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Cuts [a,b) are removed from the programme (they may overlap or be unsorted and are merged first). A time after a cut shifts left by the removed length; a time inside a cut maps to the cut point. Cues [start,end,text] are mapped and dropped when the mapped end is not after the mapped start.

Why this case matters

Subtitle timing defects shift, hide or overlap captions that viewers depend on for comprehension and accessibility.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
