Sync fix

Subtitle shifter

Audio runs 2 seconds late? Subs appear before the line lands? Shift every cue in the file by the same offset — positive to delay, negative to advance — and download the fixed file.

How to pick the offset

• Play the video and note when a line is spoken vs when the subtitle appears.
• Subs early → use a positive shift. Subs late → negative.
• Subtitles clamp at 0:00 — shifting earlier than the video start truncates leading cues, which is usually what you want.
