Relative Video Time

See the current video time relative to a user-defined starting point on YouTube videos or other videos (mp4, webm, ogg, and mkv supported) — perfect for timing sections within videos! Seek to the time you want to mark as the beginning, press "B", then the overlay will show you the current video time relative to that point. You can even copy the current relative time to your clipboard with a single click. Use the < and > keys to navigate between frames in raw videos like you can on YouTube videos.
