Magic Lantern Firmware Wiki

Clean HDMI display[]

Magic Lantern allows you to use an external HDMI recording device, such as Atomos Ninja or Hyperdeck Shuttle, by removing the focus box and other graphics from the display.

In ML menus[]

  • Unified: LiveV -> ClearScreen -> WhenIdle (or Display -> Clear when Idle)
  • AJ: Kill Overlay


While these devices are capable of recording 1080p 422 signals, the HDMI output from the Canon HDMI is limited to 1620x1080 (3:2) while the camera is not recording. This requires the user to crop the footage from the external recorder to 1620x910 (16:9) and then resize it to either 1280x720 (79%) or 1920x1080 (119%).

When the camera is recording, HDMI output resolution is limited to only 720x480 (effective image resolution is 640x388, which represents a stretched 3:2 frame).
