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. Show the rail

Play any video, then click the Filmina toolbar icon and show the rail, or press Alt+Shift+S on the page. A slim rail appears beside the video. Drag it anywhere, or fold it into a single button with its chevron.

4. Try a look

Open Looks on the rail and rest the pointer on any card to preview it on the video. Click to keep it. Press / to search. The change happens while the video keeps playing, with no reload.

5. Add an effect and tune

FX adds grain, glow, weather or tape on top of the look, and Tune has Quick and Advanced sliders. Hold A/B to compare with the original. Filmina remembers your choice per site.

6. Switch it off any time

Press Alt+Shift+C from any tab to turn Filmina off and on again.
