Auto exposure
Also known as: AE, automatic exposure
The camera's automatic system that reads the scene and sets shutter speed, ISO and sometimes aperture so each frame lands at a target brightness.

What it means
Auto exposure, usually shortened to AE, is the loop inside a camera that keeps the picture from turning too dark or too bright. It measures the light coming through the lens many times per second and adjusts the settings it controls until the image matches a target brightness.
Action cameras and most drones have a fixed Aperture, so their AE has only two levers: shutter speed and ISO. In bright sun the shutter gets very fast, which freezes motion but can make footage look choppy. In a forest or at dusk the shutter slows and ISO climbs, bringing blur and grain. For people filming sport, AE is the reason a camera can be clipped on and forgotten for a whole day.
How it works in practice
The camera decides what correct means through Metering. Most models average the whole frame or weight the center, which works until something very bright or very dark dominates the view. That is when snow turns grey and a rider against the sky becomes a silhouette.
You can steer AE without going fully manual. Exposure compensation shifts the target up or down, an ISO ceiling limits grain, and a shutter limit or an ND filter keeps motion blur natural. On a drone, the DJI Fly app offers Auto and Pro camera modes, and Pro lets you set shutter and ISO yourself when AE keeps guessing wrong.
What to watch out for
AE reacts to everything that changes the frame. Riding from shade into sun, turning toward a low sun, or a dark jacket filling the lens all trigger a correction, and on screen that looks like brightness pumping up and down. That kind of Exposure hunting is hard to repair later.
It also cannot read context. Under flat light on snow it happily produces a dull, low-contrast image that is technically exposed. When the light is steady, use AE lock or set exposure manually so cuts between clips match. Night sessions show the limits most clearly, as ISO climbs until shadows turn to mush.
How RawClip handles it
RawClip does not correct exposure, so brightness in the finished highlight is whatever your camera recorded. The model looks for action, peaks and faces in every clip and can still find them in imperfect footage, but a well exposed file gives it more to work with. Set AE sensibly before you ride.
