Ratings and Reviews
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!
This extension is super great! I just have 2 small suggestions that I think would make it much better. One, I wish the video didn't pause for a split-second as you're changing the speeds and two, I wish there was a small, slightly transparent notification that you could put in the corner so you could see what speed the video is playing at without actually having to change the speed to see.
Developer Response ,
Hi shamrocksread, thanks so much for the feedback and kind review! There is actually a shortcut to show a notification with the speed you are on without having to change the speed (the default key is “V”, but you can change this in the preferences if you’d like). The split second pausing is unfortunately a known issue actually caused by Safari’s video processing that happens anytime a playback setting is changed.
Perfect for Speeding Through Videos/Audio
When I listen to podcasts, I always utilize the 1.5x-2x speed and wanted to figure out how to do that on my Macbook. I came across this app and it works perfectly!! I don't even have to open the app in order to accelerate a video because I have it as an extension in Safari. I simply press "D" to speed up the video and "S" to slow it down (this shortcut can also be edited). If you are like me and enjoy consuming content rapidly, this is the app for you!
