When to use it
When second-level shifting overshoots. Common offsets: -80ms (subtitle appears too late), +120ms (subtitle appears too early), -250ms (frame-accurate alignment).
How the shift works
Every cue's start and end time is offset by the same number of milliseconds. Negative results are clamped to zero unless clamping is disabled.
