Changing the EUMETSAT visualisation or source resolution reloads the current/previous pair in the background.
Time
In live mode the date/time follows UTC automatically. Dragging the slider switches to archived manual mode and immediately scrubs the optical-flow interpolation within the loaded 10-minute pair; crossing into another pair loads the appropriate archived frames.
Live settings
Colour
Night look
Balanced all-day is intended for normal use without switching presets. The daylight and terminator presets are mainly calibration/testing references. Moving a colour/night slider switches the style to Custom.
Diagnostics
Accelerated motion also works at archived/manual times. Debug views expose the actual regularized motion field used by the shader, which makes sparse or false motion much easier to diagnose.
FROM/TO are the exact raw EUMETSAT endpoints of the currently loaded pair. They clear automatically when scrubbing or when the pair changes, and are disabled while the selected manual time is not covered by the active pair.
