I have been using this for several weeks now and I like it. It speeds up all kinds of Videos even the Ads on YouTube that can't be skipped or sped up normally. It will even speed Facebook Live broadcasts. If you join a live webinar late and can rewind the playhead then you can speed up the content. When the playhead catches up to the LIVE content it will automatically slow down and go back to real time. From my testing if any video plays in your browser then this will speed it up. My only gripes are that it disables the speed controls in YouTube (and probably other video players). Once you install this extension you MUST use this extension to control the speed of video playback. This can be confusing if you are used to using YouTube's settings panel. I wish they still worked. Also, when you are in full screen mode and you use the hotkeys there is no visual indicator to show how fast you are playing back a video. For instance in "Video Speed Controller" (a similar Chrome extension) it will display briefly on the screen that you are at 1.50x or 1.60x as you increment up or down the speed controls. I would rather have that than the ding sound this makes which does tell you much other than a change was made. (Actually I find the ding sound to be intrusive and annoying and would like to turn it off. High speed playback requires more concentration and the ding ruins it.) Sometimes the controller will be set (I prefer 1.50x ) and a video will playback at normal speed until I make another adjustment or start and stop the video - then it will speed up. Or a video will playback at normal speed and then start to speed up midway through. This can be startling. I’d like to see more consistency. Finally, I wish there was to set it so it automatically resets the playback speed to normal speed or contains the speed settings to ONE browser tab. Because this a browser extension If you have multiple tabs open all your videos will receive the same setting. Or if you go from one video the next all the video will be sped up say 2x, which may not be appropriate for that content, until you change it. (That’s also a reason why someone might want to use the inbuilt YouTube speed controls instead of this - because their controls are on a per video basis, whereas this is on a global basis). Overall these are somewhat minor complaints that would make the product better if they are added in or addressed. I still gave it 5 stars because for my use case it works as promised. I watch private educational content sometimes on private class websites that don't always use YT or have speed controls in their settings and this has allowed me to consume hours of content in sometimes less than half the time.

I bought this to use with periscope, but the videos I’ve tried won’t follow any of the geometry settings (the rotation options don’t even make sense), won’t follow the color processing in PiP, and insists on rotating the videos 90° clockwise in PiP (and as noted, won’t adjust them)... So…it’s unusable for me. I wish I could get my money back but instead I’ll just leave this warning.
