Merge Lines with Same Time Codes

Merge consecutive subtitle lines whose start and end times are (almost) identical into one entry that combines the texts.

Options

Max ms difference — Maximum difference in start and end times that still counts as "same time codes"
Make dialog — Format the merged text as a two-speaker dialog (using the dash style from General settings)
Auto break — Re-break the merged text into balanced lines
