Need to remove unnecessary black bars from this youtube video you're watching? Ultrawidify is here for you. 

If the extension stretches the video instead of cropping, you're experiencing a Google Chrome bug. Go to chrome://flags/#use-angle and select D3D9.

⚠️ Features automatic aspect ratio detection (not all sites are supported — support may vary from site to site)
✅  Supports primarily youtube, vimeo, twitch, netflix, but will try to work on any website
↔️ Supports both cropping and stretching
✅ Works with youtube theater mode

❓ How do I use it?
If the site does not utilize DRM, you can just sit back and let autodetection handle everything for you. On sites that use DRM — or on videos where autodetection proves unreliable — you can either use the extension popup or the keyboard shortcuts (note that extension shortcuts do not override site's default shortcuts) to set the aspect ratio manually.

Risk impact

Ultrawidify requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install Ultrawidify if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Ultrawidify has earned a good reputation and can be trusted.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.

Only working extension I have come across so far. Good: - Gives useful error messages. Bad: - A bit complex UI, but I don't mint it because it gives you plenty of options.

I had a bug on Netflix where when I went into full screen mode, my movie/show would be stretched out. It was annoying me so I did a search on reddit which brought me to here. This program told me what was wrong (it was a hardware acceleration issue and I had to select a different GPU processing engine or something) So though I didnt use the product for what it was mainly intended for, it did diagnose the problem and pretty much resolved it.
