FA-78003 / Subtitle cue timing / Member archive

Minimum cue duration extension: never shorten · case 03

Short cues crowded by a close neighbour get even shorter or inverted.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Cues [start,end] may be unsorted; the neighbour of a cue is the next cue in (start, input index) order. A cue shorter than min_dur has its end extended to start+min_dur, limited to neighbour_start - min_gap; an end is never shortened. Output keeps input order.

Why this case matters

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

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: never shorten	`[[500, 460], [500, 2500], [800, 960], [1000, 960], [1000, 3000]]`	`[[500, 800], [500, 2500], [800, 1799], [1000, 1001], [1000, 3000]]`	Failed
