Really nice to have a way to mitigate reverse burn-in from watching 16:9 YouTube content on 21:9 oled displays.

it looks good, but makes the page lag a lot

I love the exstension but I'd also love if it worked in limited funcionality on other websites too. Like I watch a video on a website and when i open to full screen it detects any black bars and adds ambient light. As someone with a ultrawide monitor it would be so usefull!

Really great extension, especially for Ultrawide OLED monitors. Makes the YouTube experience more premium!

App works great in theater and other non-full screen modes, however in full screen the playback seems to freeze until i scroll down. Not sure if I have the extension set up incorrectly or not. If it worked in full screen it would be 5 stars for me.

edit: Incompatible with UltraWideo extension, having the extension on causes ambient video playback to not work. changed back to 5 stars as extension works perfectly now.

This extension in a godsend for Ultrawide OLED monitors. As you know, Youtube does not allow videos in other formats except 16:9 (at most 18:9 on phones) so ultrawide (21:9 and larger) monitors get giant black bars on the side. With OLED monitors that is a big no-no, as over time the middle of the screen will start slowly burning in, and the sides will remain brighter. You want to actively use the entire screen to get uniform burn-in over time, and this extension fixes that problem.

This was EXACTLY what I was looking for to fill in those black bars on youtube videos! So much better :)

Works as advertised. The settings are a little unintuitive at first but they make more sense as you play around with them.

everything about the extension is fine, but the only issue is that 'fade in duration' option resets every time I open youtube in a new tab.
or maybe I might be doing something wrong.

Beautiful extension. I use this to reduce uneven burn-in from the black bars on my 21:9 and it just looks stunning. But it has way more functionality too. So many options, and it even removes black bars better than dedicated extensions for that. It's like ambient mode got an upgrade

Absolutely incredible but the latest update introduced a bug. When the mouse cursor hovers on the progress bar or the edges of the video (in regular mode not theater) it causes massive flickering and sometimes completely removes the video and only leaves the ambient light effect I hope this gets fixed soon.

EDIT: The issue seems to be fixed now :) Cheers to the developer for such a quick response and fix.

One of the best extensions ever made! Performs way better than YouTube's own ambient mode on my hardware and uses less resources too.
