Finds black bars that are part of the video itself and takes them out, without cropping the picture.
Cinewide is a Chrome extension for ultrawide monitors. It finds the real picture inside a video, even when the black bars are part of the video itself, and fits it to your screen without cropping it.
Free to use. No account needed.

Fills the screen. The edges of the picture are cropped, and Cinewide tells you.
For video whose picture cannot be measured, such as protected streams: 2.39:1, 2.0:1, 1.85:1 and 16:9, one press each.
Zoom and move the picture by hand, on top of any mode.
On YouTube, Vimeo and Twitch from the start. On every other site, only when you press: a key, or the Cinewide icon in the toolbar.
Cinewide changes how your browser shows the video, not the video. Press again and it is as it was.
Cinewide speaks Vietnamese in a browser that is in Vietnamese, and English in any other.
No analytics. Nothing about what you watch or where you watch it is ever sent.
