Browser extension that increases the display size of videos by removing unnecessary padding bars

Image from store Video Plus
Description from store Video Plus — more video space So you want to watch that wide screen video on the entire surface of your 21:9 screen? No such luck if the uploader of the video for some reason decided to add black padding bars, which are not noticed on 16:9 screens. On a wider screen, you are stuck with black bars on all 4 sides of the video. For example a 21:9 video padded to 16:9 on a 21:9 screen wastes mode than 40% of the screen on black bars — and this is very common for example for music videos on YouTube or older movies. This extension changes that. While a video is played, it keeps scanning it for padding bars and zooms the video to crop of the edges as far as it is possible without stretching it or pushing content out to the sides. All black bars are effectively removed. Technical note: To do its magic, this extension needs to know the actual dimensions of the video without padding, and the maximum area the video can cover without colliding with other page elements. Both can change without explicit notice, and for the former there isn't even a direct way to get it. This extension therefore takes considerable shortcuts to keep the CUP usage low: - The actual video dimensions (ignoring any added padding) have to be read from video frames: - Check whether the color is uniform along each edge, and if it is, probe how far inward that solid color goes. - This is probed at three places along each edge and the minimum of these probes is seen as padding in that frame and is cropped off. - That check has to be performed on individual frames and, due to the way video streaming works in browsers, cant be done ahead of time (without considerable overhead and complications). - As to not rely on a single frame that may not represent the entire video, the check is repeated every 0.3 to 2.5 seconds, depending on the previous rate of changes. - To prevent stuttering due to frequently changing video zoom levels and positions, a delay of 5 seconds (configurable) is added before fully updating the video size. - In addition to that, the screen area that is available for the video may change. This is re-evaluated after a number of user <--> page interactions. Permissions used: - "Access your data for all websites", "Access browser tabs" and "Access browser activity during navigation": This extension can be configured (see its options page) to work on every website, so it needs to know when they are loaded and be allowed to access them. It only does that for the pages you chose (youtube.com by default) and will never send data anywhere. - "Display notifications to you": Tell you when something goes wrong, (so you should never see this ;) ).

  • (2021-08-03) Mark Jonhson: Finally a widescreen application that seems to work sensibly on a 32:9 screen. Big Thanks for that! Works on . . . - Facebook Watch - Banned.video - YouTube (but some "normal" aspect ratio videos cause strange zoom & crop problems, but of course you can turn this off then.) ARGH! UpDate:This not work correctly anymore! Now it's only stretch picture left to right, but not up to down :(
  • (2021-07-16) Aiven: This extension is the bees knees. I honestly love it so much. It provides widescreen to youtube videos totally seamless. Also when you watch a video and they for some reason added black bars on top and bottom, you get the coolest zoom in (example Harry Mack on youtube). Everyone should have this, it should have 10M downloads!
  • (2021-03-04) Rainbow Pearce: Это лучшее расширение по убиранию чёрных полос что я видел! Я бы даже сказал что оно использует ИИ чтобы обнаружить чёрные полосы и убрать их. хаха

  • (2019-07-14) Robin Whiting: This is great! Has a beautiful, discrete fade animation when switching between aspect ratios and it all works very well. No juddering and stuttering unlike some other, similar extensions.
  • (2019-04-17) Александр: Работает лучше всех, на автомате подстраивается под окно, если возможно, очень удобно.
  • (2019-01-08) Николай Петров: С установками по умолчанию не заработал, пришлось немного переписать код
  • (2018-09-16) Max Link: definetly the best tool for getting any 21:9 ratio image into "full" fullscreen. it has SMOOTH animations and works perfect
  • (2018-08-29) Christian Lancaster: Perfect Widescreen Video - Adjusted settings .html5-main-video { width: 100% !important; height: 133% !important; top: -16.5% !important; left: 0 !important;}

  • (2020-07-12, v: Ethan Pierce: can't fullscreen
    I can't put the videos on fullscreen while the extension is active. :(
  • (2019-09-14, v: Ken Otwell: Does not work on Amazon Prime Movies
    I turned on the gray mesh and it only shows on left and right borders. The top and bottom are still jet black - so I presume those are actually part of the video. Therefore, this extension does not solve my problem. Thanks.
