About this manual

This document outlines the release notes for the AtomOS 9.3 firmware update specifically designed for the Atomos SUMO 19 recorder. A critical change in this version is that all users must now activate the ProRes RAW codec; without activation, the device will default to ProRes HQ when a RAW source is detected.

The update introduces several new features and improvements, including social media-focused frame guides for various aspect ratios (Instagram, Facebook, Twitter), a 9 Grid overlay for composition, and options to legalize input signal levels. It also adds anamorphic de-squeeze modes for specific lenses, IRE % labeling on the false color scale, rolling file naming capabilities, support for 17:9 DCI letterbox resolution, and an Interlaced Display mode.
