Accelerate is a Safari extension with powerful, customizable features for controlling video playback and speed.

• Control playback speed of HTML5 video
• Personalize keyboard shortcuts for common media controls, e.g., play/pause, skipping, mute, Picture-in-Picture, etc.
• Global shortcuts to control Safari playback while using other apps
• Supports Picture-in-Picture and AirPlay

By default, you can use the following keys on your keyboard to control video speed:

A: Toggle 2x Speed
V: Show Current Speed
P: Enter Picture in Picture

You can customize these and create additional shortcuts for the other playback actions available in Accelerate.

Great but have recommendation

I am really enjoying the functionality of the extension. I use this as a medical student to more quickly navigate through lectures.

One additional feature that would make this perfect for me would be menu commands to make universal keyboard shortcuts. An example this could be used is during recorded lectures and taking notes. If i miss a particular portion of the lecture audio and I need to skip backwards to get it, without exiting the note taking application, I would be able to do that. I cant tell you how much I am going in and out of applications when I just want to have a global shortcut for pause/play, skip forward and skip backward. Maybe Accelerate can do this and I just missed it. Great applicaiton none the less!

Its good for being one of the only fast forwards for safari

Im still a little confused sometimes on how to use it but the creator sent me to an faq page that helped me out. Im getting used to it, but it could still be a little clearer with instrcutions. though, it does what its supposed to do so it should get 5 stars. I also still dont like that it wans you that it could be steaking passwords, but the creator also explained that, and i guess ill just have to trust him if i want to watch netflix faster lol

Developer Response ,

Hi userjlv, I promise that Accelerate doesn't collect any personal info whatsoever, and you can see an explanation for the warning in my privacy policy, since it's a common concern with many Safari extensions. If you need help with getting the extension to work, there is an FAQ available on the Accelerate website with troubleshooting instructions. ( If you have other questions, feel free to email me and I'd be glad to answer them.

MacOS ver.: VGood, iOS ver.: Default Settings only

Again, great implementation on MacOS, but since I started using the iDevice variant, a) every input setting on the General app tab refuses to acknowledge changes to the playback speed multipliers or increment; on the Shortcuts app tab b) every created shortcut ignores user input and reverts to DEFAULT settings, and c) every Standard shortcut that is edited either resists editing entirely or replaces the Standard shortcut with the Default values from a newly created shortcut (in order to preserve the Standard shortcuts, the app must be clean re-installed).
If the speed notification corner or the Keyboard shorts in the Standard shortcuts were in conflict with our workflow, I'd have to find another solution. Thankfully, the Standard shortcuts and General settings are tolerable. thx
