Both. Lock the ratio and one dimension follows from the other, which is what you want almost always. Unlock it and you get exactly the numbers you typed, at the cost of stretching — which on video means every face in the frame is slightly too wide. When you need a different shape, crop or letterbox rather than stretch.
