Important details

Captures stay private to your account. They are not published to Shared videos unless you explicitly save and share them later.
Starting in the middle of a video is supported. The saved lines keep their original YouTube timestamps, and the player opens and stops around the captured segment.
Each capture can be up to 10 minutes. For longer videos, capture the parts you want separately. Free and Pro usage limits still apply.
