Frequently asked questions
How do I shift SRT subtitles?
Paste the SRT content, enter a positive number to delay subtitles or a negative number to make them appear earlier, then copy or download the adjusted file.
Can I shift VTT timestamps too?
Yes. ClipFlow preserves VTT period-based milliseconds and SRT comma-based milliseconds while shifting every timestamp.
What happens if a timestamp becomes negative?
Any shifted timestamp that would fall before the start of the video is safely clamped to 00:00:00.000.
Are subtitle files uploaded?
No. Timestamp calculations happen locally inside your browser, and the subtitle content never leaves your device.
