Install & first run

1. Install from the Chrome Web Store

Filmina ships as a single extension for Chrome, Edge, Brave, and Opera. Click Install and accept the permissions prompt. Filmina asks for activeTab, storage, and tabs — nothing that lets us read page content or your browsing history.

2. Open any video

Visit YouTube, Vimeo, Twitch, or any page with a <video> element. Filmina auto-attaches as soon as the player loads — you'll see a small dot on the toolbar badge confirming it's active.

3. Pop the panel

Click the toolbar icon or press Alt+Shift+C to toggle filters. The popup has three tabs:

• Now — quick picks and live tune sliders
• Modes — the full preset library with a thumbnail gallery
• More — site memory, pipeline mode, license, themes

4. Try a preset

Click any thumbnail in Modes to apply it. The change happens instantly while the video keeps playing — no reload, no buffer.

5. Tune to taste

Hop back to Now → Tune to nudge brightness, contrast, saturation, and temperature. Filmina remembers your tweaks per site.

6. (Optional) Open the Studio

Press Alt+Shift+S while a video is playing to pop out the full Studio editor in its own picture-in-picture window. Studio gives you the advanced tune sliders, the FX stack, before/after compare, and custom-look management.
