Resolution scaling is changing the size of a video's resolution to make it work better for different screens or conditions. It's commonly used in streaming, gaming, and video production. There are two main types: downscaling and upscaling. Resolution scaling adapts video to different devices and internet speeds. Without it, videos might look pixelated, blurry, or take too long to load. Thanks to advanced tools and techniques, scaling has become smarter, ensuring videos look great no matter where or how you watch them. Whether streaming on your phone or enjoying a movie on a 4K TV, resolution scaling ensures a smooth viewing experience
