A userscript that sharpens videos across any number of streaming sites. This applies a sharpening filter using SVG filters and CSS. It also slightly adjusts the contrast and brightness to maintain overall video quality. Check out my other script that sharpens videos using CSS filter if this one lags or is resource intensive here.

Note, although the script is enabled on all sites, to apply the sharpening for that site, you need to click on Toggle Video Sharpener option from Tampermonkey.

In my testing, this one seems to lag on Firefox but works well on Microsoft Edge. This script was inspired by Youtube Video Sharpener script.
