This Safari extension allows you to:

・Change the playback speed of web videos/audios up to 16x the original speed.

・Set playback speeds that include a decimal point, such as 2.125x.

・Access a wide variety of customization features.

This extension works on Safari.

The playback speeds that can be set range from 0x to 16x, including speeds with decimal points.

How to change playback speed
1. Go to the site on Safari (e.g. YouTube) where the target video/audio is located
2. Open a popup for this extension
3. Change the playback speed to your preference by clicking the slider that appears or the one-click button that allows you to change to the set playback speed

Customizable Items
・The highest value (the highest speed of the video/audio), the lowest value (the lowest speed of the video/audio), and the step on the slider.
・Default speed for playback, eliminating the need to set the speed every time.
・Playback speed settings, allowing you to decide whether the last-used playback speed will remain set for other videos/audios.
・One-click buttons to change playback speed (multiple settings possible, up to 24 buttons)

Additional Information
・If the target video/audio is embedded from an external site, the playback speed can be changed by navigating to that external site. In addition, you cannot change the speed of non-HTML5 video/audio. (However, the video/audio on most websites is HTML5, so this extension will function on most websites.)
・Due to the large number of sites, we cannot guarantee that this extension will work on all sites. Users can inquire if this extension will work on a particular site before installing it. Please contact us with the URL of the video/audio in question and we will respond within 24 hours.
・Changing the playback speed with the keyboard is not supported.
