# If you do not override all of the settings in the AutomatedLevelSequenceCapture then the other settings are inherited
# from Unreal's Class Default Object (CDO). Previous versions of Unreal (4.19 and below) stored the Render to Movie UI's settings in config files. Config
# values are automatically loaded and applied to the CDO when the editor starts up. Unreal 4.20 and above now store the UI settings in a unique
# instance in the config files, so modifications to the Render to Movie UI will no longer affect the CDO. However, legacy projects that are upgrading
# from 4.19 to 4.20 may end up with the CDO being modified by their last Render to Movie UI settings. The CDO settings for AutomatedLevelSequenceCapture
# is stored in /Engine/Saved/Config/<Platform>/EditorSettings.ini under the sections labeled "[/Script/MovieSceneCapture.AutomatedLevelSequenceCapture]",
# and "[/Script/LevelSequence.LevelSequenceBurnInOptions]" .
# If you happen to upgrade your engine and this file persists, then the old settings will be applied by default to the CDO, and thus to the instance created
# in Python. If you want to ensure that your Python instances come with default settings set via C++ then you should remove that section from the config file
# on each users machine, or you should override every possible setting via Python (see below).
