FrameTrap Keeps a Phone-Captured Screen Square

Field notes

The tool registers the edges of a physical TV or monitor, follows the screen as the phone moves, and produces a corrected composition for recording or Twitch output. Users can combine the display with selfie, raw-camera, or image-overlay layers, with a stated 1920 × 1080 H.264/AAC target. The site says analysis stays on the Android device and identifies direct Twitch streaming as being in private testing, while account controls and in-app chat are planned for a later milestone.
