Adjust All Times

Shift all subtitle timings by a fixed amount.

• Menu: Synchronization → Adjust all times...

<!-- Screenshot: Adjust all times window -->

Options

• Adjustment — Time amount to shift
• Show earlier / Show later — Apply the adjustment as a negative or positive shift
• Apply to — All lines, selected lines only, or selected lines and forward

The window remembers its position and stays open across New/Open, so adjustments can be made while continuing to work on the subtitle.

Keyboard shortcuts

• Shift/Ctrl/Alt + Left or Right arrow — Show earlier/later
  • Time codes shown as milliseconds: 10 ms / 100 ms / 500 ms
  • Time codes shown as frames: 1 frame / 10 frames / 1 second

Note: "Selected lines and forward" applies the shift to the currently selected lines and every line after them.
