Overview

Product summary

Review the store description, core capabilities, and common use cases.

Adds an adjustable blur bar to cover subtitles that are embedded into a YouTube video. Blur bar comes with a hover-able panel that will reveal the subtitles(which also can be accessed with controls). This is a great tool for language learners as often times people put their subtitles within the YouTube video itself and not the CC. You can throw the bar over the subtitles and reveal them to check if you are translating it correctly within your head. I found this extremely useful while studying Japanese and figured I could help some fellow learners.

HOW TO USE:

Simply load up the YouTube video of your choice and our extension will inject a B button within the YouTube video player controls. Click this button to reveal the Blur Bar then drag and resize as you see fit. The Blur Bar comes equipped with a hover-able square at the top left corner of the bar in which when hovered it will reveal the subtitles. You can also access this feature by clicking the "S" key.

OPTIONS:

There is a popup located in your extensions at the top right corner of the browser, click it to reveal your options. As of now we have two options available.

Pause-on-Hover option allows you to toggle whether or not the video pauses and rewinds upon hovering the reveal square or pressing S.

Perfect for blocking onscreen chat in Twitch vod uploads. Only feature I can think to suggest would be save the size of the blur box so I don't have to resize it every video.

please make it available for every website as youtube is not the only website which needs a blur for learning languages

Awesome extension though I think it could have been implemented a bit cleaner since it's a bit fiddly, but it does what it needs to do and is simple. Also sometimes the button doesn't show up on a video, but I think this is due to conflicts with other extensions that also use custom buttons, so perhaps not their fault, still a great plugin.

Really useful! The functionality to pause and hide blurbar is great. Would love to have some more customizability, e.g changing hotkey and having different hotkeys for hide&pause and hide only. Please consider adding those :)

This tool is great!! I didn't know that we have something like this before. Having subtitles running in YouTube videos sometimes distracts me, but now I can use this tool to actively cover the subtitles, which helps me focus on the content of the videos. And I can uncover it whenever I want to. Awesome!

I usually change the position and shape of the blur bar. And if I turn off and on again, it goes to default position/ shape. Please make it remember my setting.
