Sensor size
Also known as: image sensor size, 1-inch sensor, optical format
The physical dimensions of a camera image sensor. Bigger sensors gather more light, so they usually give cleaner low-light footage and wider dynamic range.

What it means
Every digital camera records onto an image sensor, and its physical size has a large effect on image quality. A larger sensor with the same number of pixels has bigger photosites, each of which collects more light. More light means less noise, smoother gradients and more dynamic range before highlights clip or shadows turn muddy.
Sensor sizes are often written as fractions such as 1/2.3 inch or 1/1.3 inch, an old naming convention that does not match the real diagonal. The practical rule is simple: the smaller the second number, the larger the sensor. Many action cameras have fairly small sensors, while some newer models and premium drones move to 1-inch class chips.
How it works in practice
You notice sensor size most at dusk, indoors and in forest shade. A small-sensor camera raises its gain to keep exposure, which adds grain and makes the camera apply heavy noise reduction. A larger sensor keeps detail longer and needs less of that smoothing.
Bigger sensors also make it easier to blur the background, though action cameras use such short focal lengths that almost everything stays in focus anyway. For drones, a larger sensor is a big part of why premium models hold detail in sunsets and night city shots.
What to watch out for
Sensor size is not the whole story. Lens quality, processing, Bitrate and the stabilization crop all shape the final image, so a camera with a slightly smaller sensor and better processing can beat a larger one with heavy compression. Compare real footage in the light you shoot in rather than spec sheets.
Larger sensors can also come with trade-offs in action use, such as more heat, shorter recording times in some modes, or a narrower field of view for the same lens. If most of your riding happens in bright sun, a small sensor may be all you need, and low-light performance matters far less.
How RawClip handles it
RawClip uses the footage exactly as your camera recorded it, so better sensor quality carries straight through to the result. Clips from different cameras can share one order, and the AI picks the strongest moments for your highlight.
