YouTube raw SBS/3D helper

Restores the raw SBS or top-bottom 3D stream on supported YouTube watch pages.

YouTube raw SBS/3D helper is a focused utility for old YouTube 3D uploads that still contain a raw stereo stream inside the player. When YouTube renders those videos through a processed canvas layer, this extension can hide that processed layer and reveal the original underlying video element instead. On supported pages, the extension enables SBS mode automatically and adds a small in- player control so you can turn the behavior on or off without leaving the video. What it does: - Works on YouTube watch pages - Detects a supported raw-video plus canvas player structure - Restores raw SBS or top-bottom 3D presentation when available - Reapplies the setting across YouTube's in-page navigation What it does not do: - It does not download or re-encode video - It does not modify videos on YouTube's servers - It does not guarantee support for every historical 3D upload This extension is intended for niche legacy 3D content where the raw SBS or top-bottom stream is still present in the browser player but hidden behind YouTube's processed rendering path.
