Frequently Asked Questions about Timestamp Marker
Does this tool cut or trim the video file?
No. It only creates time markers and controls player playback. The video remains securely hosted on YouTube.
How do generated timestamp links work?
Generated links use official YouTube timestamp parameters (e.g., https://www.youtube.com/watch?v=ID&t=207s) to jump directly to the exact second.
Are markers stored separately per video?
Yes! Markers are persisted in your local browser storage indexed by each unique YouTube video ID.
