Lucid 0.3.5

Video super-resolution for Apple silicon.

Requires Apple silicon and macOS 26.

Since 0.3.0

• Works on any site, not just the ones it was tuned on. Every setting used to mean something different depending on how much the video was being stretched — the same numbers were roughly twice as strong on a YouTube 240p player as on the test clip, which is why it looked over-processed there. Gains are now normalised by the upscale factor, and the sharpening lobe is pinned to a fixed pixel spacing.
• Deblocking sets its own strength from the picture. Compression leaves steps on the transform grid that are not there off it, so the frame itself says how damaged a stream is. No knob, no per-site setting.
• A control panel that stays open. Click the aperture in the menu bar: on/off, four quality settings, and adjustments and stages when you want them. Everything applies on the next frame.
• 144p is covered. It was being rejected for being small, which was backwards.
• Draws through an extension-origin iframe, so sites whose security policy blocks a loopback connection are handled by the same path as everything else rather than a separate overlay.
• Menu bar only, no Dock icon — a Dock icon makes it a regular app, and activating one throws you out of a full-screen video.

Installing

1. Open the disk image and drag Lucid to Applications.
2. Not notarised, so clear the quarantine flag once:

   xattr -dr com.apple.quarantine /Applications/Lucid.app
   

3. Open Lucid and grant Screen Recording.
4. Load the companion: chrome://extensions → Developer mode → Load unpacked → the BrowserExtension folder from a checkout.

Known limits

• DRM video is impossible; the frames never reach the page.
• One video at a time, top frame only.
• The loopback bridge is not authenticated.
• Performance measured only on an M4 Pro.
