CRT Video Stretch

Overview

I created this extension because I connect my PC to a CRT TV using an HDMI-to-composite video converter. The problem I ran into is that most modern video is designed for 16:9 displays, and even older 4:3 content is often presented inside a 16:9 player with pillar boxes on the sides. When that 16:9 output is converted to 4:3 for a CRT, the result is often wrong: -The image becomes horizontally squished -Black bars appear on the sides CRT Video Stretch fixes this by allowing you to horizontally stretch HTML5 videos directly in the browser, restoring the correct proportions on a 4:3 display and cropping away unwanted pillarboxing. What this extension does -Applies a horizontal stretch to HTML5 <video> elements -Corrects 16:9 → 4:3 squashing caused by HDMI-to-analog video converters -Crops pillar boxes added by modern video players -Automatically reapplies your saved settings to new videos -Works on sites like YouTube and other HTML5 video platforms -Designed for retro and legacy display setups -This extension is especially useful if you: -Use a CRT television as a display -Output video through HDMI-to-composite or HDMI-to-component converters -Watch modern web video on 4:3 hardware -Want consistent video sizing without manually adjusting every video Features: Adjustable horizontal and vertical scaling -Left/right up/down centering -Live preview while adjusting -Optional per-site settings -One-click preset for correcting 16:9 → 4:3 output -Settings are stored locally and automatically applied Privacy: -This extension does not collect or transmit data. -All settings are stored locally using Chrome’s built-in storage. CRT Video Stretch is a simple utility for making modern web video look correct on classic 4:3 displays.
