The PIX 240/240i HD playback functionality is a built-in feature of the Sound Devices PIX 240/240i portable field recorder that enables instant, on-set viewing of high-definition video. It allows users to review, playback, and loop Apple ProRes or Avid DNxHD files directly from a 5″ screen via SDI or HDMI outputs, often used for immediate video verification without needing to check the camera.
