The SRT renumber tool numbers the cues of an SRT file again from 1 after cutting or merging parts. Cues numbered 1, 2, 5, 6 become 1, 2, 3, 4 (result: 4 cues). It is useful when you joined or trimmed subtitle files and the numbers have gaps.

Facts that matter here
- Formula: cue number = position in the file, starting from 1, applied to the numbers in the table below.
- Assumption: cues keep their order in the file, and only the numbers change.
- Renumber after the last edit, not before, so that the numbers stay in order.
- Every number in the table follows from the formula above; none was measured on a real recording.
