Vector-Ultra (v5.7) — Black Bar Remover Script

2026-07-10

🚀 Project Spotlight

First project uploaded! Finally using Github after like 3 years 😂

This one is a Tampermonkey script to tweak the player interface. It works in Brave, should work in other Chromium browsers. The main purpose is to remove the black bars during full screen and theatre mode video playback on YouTube. You can also have it work with short format videos as well to zoom them to a desired size. Works great and is fully automatic after setting it up. Has some other features like subtitle downloading but they're not working. Very happy with how this turned out — I use it every day. I couldn't find anything else like it online.

Core Capabilities

Feature	How it works	Why use it
Ghost UI	Hides the top navigation bar while playing; hover to reveal. (possibly working)	Distraction-free, cinematic viewing without algorithm bait.
Smart Fit	Auto-scales landscape videos and Shorts to eliminate black bars. (99% of the reason to use this script)	Maximizes screen real estate for your current monitor.
Dual Subs & Anki	Displays two caption tracks at once and copies timestamped text. (broken)	Language acquisition and drilling translated lyrics.
A-B Looper	Set custom start and end points to loop a specific clip. (50/50 if this made it in)	Rhythm practice or breaking down complex video segments.

🛠️ How to Deploy Vector-Ultra

Grab Tampermonkey for your browser (Chrome, Firefox, Brave, or Edge).
Load the script (~1 minute): open the Tampermonkey dashboard, click "Create a new script", clear the default template, paste the raw Vector-Ultra code from the repository, and hit save.
Initialize on YouTube: open any video. You'll immediately notice the UI changes, and a new V-ULTRA command button floating in the top-right of your screen.
Command the panel: click the V-ULTRA button to open the command panel, where you can bind zoom presets to specific channels.

Always follow best security practices when downloading and using scripts online.
