Generative Audio Visual ( Week 2 )

In Week 2, we explored two important concepts in video production: Ratio and Frames Per Second (FPS).

Definition of Ratio:

A ratio is a way of expressing the relationship between width and height in a video. It's written as two numbers separated by a colon, like 16:9.

Resolution Calculation:

The height resolution is found by dividing the width resolution by the width ratio multiplied by the height ratio.

Converting Resolutions:

To change resolution while keeping the same ratio, we use formulas. For example, to find the new height, you divide the original height by the original width and then multiply by the new width.

Standard Ratios:

Common ratios are 16:9 (widescreen) and 4:3 (standard).

FPS Definition:

FPS stands for Frames Per Second, representing the number of images displayed in one second. It's what makes still images look like they're in motion.

Creating Motion:

FPS is crucial for making videos. More FPS means smoother motion, bringing images to life.

Historical Frame Rates:

In early silent films, frame rates ranged from 16 to 24 fps.

Smooth Motion:

Higher FPS results in smoother motion. Common rates include 24 fps for movies, 30 fps for TV and online videos, and even higher rates like 60 fps for video games.

In conclusion, understanding the ratio helps us maintain the right proportions in our videos, while FPS determines how smoothly the motion appears. Both are crucial in creating engaging and realistic video content.
