FA-77988 / Subtitle cue timing / Member archive

Minimum gap and chaining between cues: gap measurement · case 03

Almost no cue is ever trimmed or chained because gaps look enormous.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

For sorted cues [start,end], compare each cue with the next start. If gap = next_start - end is below min_gap, the end is trimmed to next_start - min_gap but never below start+1. If min_gap <= gap < chain, the end is extended to next_start - min_gap. Larger gaps are untouched.

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: gap measurement	`[[0, 1000], [900, 2000]]`	`[[0, 800], [900, 2000]]`	Failed
