Clean Aperture

Problem

Many videos and images have black bars (letterboxing or pillarboxing) that waste cell space and look sloppy in a grid.

Solution

Clean Aperture automatically detects letterbox/pillarbox borders and crops them out, displaying only the active image area. Detection uses pixel-level border scanning.

Tier Availability

  • Free: Not available.
  • Plus / Pro: Automatic letterbox detection and cropping.

UI Flow

  1. Enable Clean Aperture from Preferences > Display or the toolbar.
  2. Media with detected black bars is automatically cropped to the active area.
  3. Disable to restore original framing.

Known Limitations

  • Detection works best on solid black borders; dark but non-black borders may not be detected.
  • Very thin borders (a few pixels) may be ignored to avoid false positives.

Marketing One-Liner

Automatically detect and crop letterbox/pillarbox borders so every cell shows only the active picture area.
