Artifact Introduction
The process of resolution enhancement is not without potential drawbacks. Upscaling, by its nature, involves creating new pixel data that was not present in the original source. This can lead to the introduction of visual artifacts such as aliasing (jagged edges), ringing (halos around sharp contrasts), or artificial textures that detract from the viewing experience. The extent of artifact introduction depends on the quality of the source video and the sophistication of the upscaling algorithm.
-
Source Resolution Limitation
The final quality of a video converted to 4K is inherently limited by the resolution of the original source material. Converting a low-resolution video (e.g., 360p) to 4K cannot magically introduce detail that was never captured. In such cases, the resulting 4K video will appear soft and lack true sharpness, even if the upscaling algorithm is of high quality. The process essentially stretches the existing pixels over a larger area, making inherent imperfections more visible.
-
Subjective Visual Perception
While objective metrics exist to measure image quality, the perceived success of resolution enhancement is often subjective. Individuals may have different preferences for sharpness, contrast, and color balance. Some viewers might prioritize a smooth, artifact-free image, even if it lacks fine detail, while others might prefer a sharper image, even if it contains some visible artifacts.
