Speed Player is a Safari extension that allows you to easily change the playback speed for any video on the web.

Speed Player does not access or collect any data from websites you visit. It requires access to read and modify websites you visit to change the speed of videos.

With Speed Player you can set a default playback speed which will be applied to every video, or videos that exceed a certain length. You can also use simple keyboard shortcuts to increase or decrease the playback rate.
