The question asks about the nature of the aspect ratio in the context of a film's frame, specifically whether it describes the proportional relationship between the width and the height of the frame.
To understand this, consider what aspect ratio means:
1. Aspect Ratio Definition: Aspect ratio is a term frequently used in visual media like films, television screens, and photographs. It describes the relationship between the width and height of an image or screen. This is commonly represented as two numbers separated by a colon (e.g., 16:9 or 4:3).
2. Implication in Films: In the context of a film's frame, the aspect ratio helps determine how the visual content appears. For example, a common aspect ratio for widescreen films is 2.35:1, which means the width is 2.35 times the height.
3. Proportional Relationship: Since aspect ratio is about the relationship between these two dimensions, it directly addresses how wide the frame is relative to its height. If the aspect ratio is 16:9, this signifies that the width of the frame is 16 units for every 9 units of height.
Given this explanation, we see that aspect ratio is indeed concerned with the proportional relationship between the width and height of a frame.
Therefore, the correct answer to the question is:
True
