To shift all the subtitles forwards or backwards by a specified amount, simply click ‘Subtitles’ > ‘Options’, then, under ‘Shift Subtitle Timing’, specify the amount (eg. -0.5s). To bring subtitles forward, use a negative number (-1.0s). To push subtitles back, use a positive number (1.0s). That’s it, done! You can choose your subtitle delay to the nearest tenth of a second.
