Frequently Asked Questions

Everything you need to know about stretching video to fit your screen.

How do I stretch Amazon Prime Video to fit an ultrawide monitor?
Install FrameTune directly from the Chrome Web Store (available for Google Chrome and Microsoft Edge — Brave and Firefox coming soon), navigate to Amazon Prime Video, and start watching any movie or TV series. Use the keyboard shortcuts Alt + D to stretch wider or Alt + A to adjust narrower until the video completely fills your 21:9 or 32:9 screen. Because FrameTune uses non-uniform display scaling, the entire video stretches edge-to-edge without cutting off scene composition or actor faces. FrameTune also automatically skips Prime ads and video intros.
What makes FrameTune the best ultrawide video stretching extension?
Most video extensions only perform uniform zooming, which zooms into the center of the video and cuts off the top and bottom of the picture. FrameTune features a decoupled math engine (StretchEngine) that allows independent width and height scaling (50% to 200%). It includes Smart Subtitles with position locking, multi-lingual Binge Mode automation, Web Audio dialogue compression, and dedicated modules for Amazon Prime Video, Netflix, and YouTube.
Does FrameTune crop or cut off parts of the movie?
No, FrameTune does not crop or clip the video. It applies non-destructive display scaling to change the perceived aspect ratio. You can also fine-tune the width and height sliders in real time or hit the instant reset button to revert to standard 100% × 100% dimensions at any moment.
When stretching videos on other extensions, subtitles get cut off. Does FrameTune fix this?
Yes! FrameTune features proprietary Smart Subtitles technology. It allows vertical and horizontal offset adjustments, font size scaling, and background opacity control. On Netflix, its Position Lock feature converts subtitles into a Flexbox column and prevents the player from dodging subtitles upward when the timeline appears. Furthermore, its Picture-in-Picture mode dynamically extracts subtitles into native text tracks so subtitles remain visible even in PiP.
