Install FrameTune directly from the Chrome Web Store (available for Google Chrome and Microsoft Edge — Brave and Firefox coming soon), open any title on Amazon Prime Video, and use the dedicated shortcuts Alt + D to stretch wider or Alt + A to narrow until the video completely fills your 21:9 or 32:9 screen.

Unlike generic extensions that interfere with Amazon's player keys, FrameTune uses the Alt modifier to prevent conflicts. It applies non-destructive display scaling without cropping, and automatically skips Amazon Prime ads and intro sequences across 30+ languages.

Traditional video zoom extensions perform destructive uniform zooming that chops off the top and bottom of movies, cutting off actors' foreheads and critical subtitles.

FrameTune uses a decoupled mathematical engine (StretchEngine) based on non-uniform CSS scaling (scaleX and scaleY) between 50% and 200%. It features Smart Subtitles with position lock, multi-lingual Binge Mode automation, Web Audio dialogue compression, and specialized modules for Amazon Prime Video, Netflix, and YouTube.

This happens because Chromium-based browsers (like Edge, Chrome, and Brave) enforce strict hardware-level Digital Rights Management (DRM) that prevents extensions from modifying the CSS transform styles of protected video streams.

For the best ultrawide experience on Netflix, we strongly recommend using Firefox with hardware acceleration disabled in browser settings. This combination allows FrameTune to stretch the video flawlessly while maintaining crisp 1080p quality. On Edge and Chrome, FrameTune provides Picture-in-Picture with live subtitle sync, mouse volume scroll, trailer volume muting, and quality badges.

Yes! This is a notorious issue with built-in monitor zoom features. FrameTune solves this completely with Smart Subtitles technology. It allows manual vertical and horizontal offset sliders, font size adjustment, and background opacity scaling.

On Netflix, its Position Lock feature converts subtitles into a Flexbox column and forces transform: none !important, preventing the Netflix player from dodging subtitles upward when timeline controls fade in. In Picture-in-Picture mode, it dynamically converts DOM subtitles into native VTTCue text tracks.

This frustrating issue occurs because streaming platforms frequently encode 21:9 cinematic movies inside a standard 16:9 container, embedding black bars directly into the video stream. When your ultrawide monitor displays that 16:9 container, it adds vertical bars on the sides, resulting in a small box surrounded by black bars on all four sides. FrameTune scales the true video feed to fill your monitor edge-to-edge.

Yes! FrameTune is universally compatible with any HTML5 video player. In addition to dedicated controllers for Amazon Prime Video, Netflix, and YouTube, it includes a Generic module with a dynamic "Add this site" quick button in the popup. It works seamlessly on Disney+, Hulu, HBO Max, Paramount+, Peacock, Apple TV+, JioHotstar, Crunchyroll, Twitch, and Vimeo.

Yes! Unlike most streaming tools that charge recurring subscriptions, FrameTune PRO is a single, lifetime payment (₹299 INR in India via UPI and RuPay, or $4.99 USD internationally via Cards and Apple Pay). There are no recurring charges. Buy it once and get all current and future PRO features forever.

Absolutely not. FrameTune has a strict zero-data-collection policy. All aspect ratio transformations and audio processing execute entirely locally on your device in browser memory. We do not track, collect, transmit, or monetize your viewing habits or personal data.

Once installed, click the puzzle piece extensions icon in the top right of your browser toolbar and pin FrameTune. Clicking the FrameTune icon opens the popup control hub where you can adjust video width/height sliders, configure Binge Mode, choose themes, and enable audio enhancements.
