- SD (640-480): lower resolution, often used in older displays and content
- HD (1280-720): high-definition resolution, suitable for most modern displays and content
- FHD (1920-1080): full high-definition resolution, higher than HD and often used in newer displays and content
- 4K (3840-2160): ultra-high definition resolution, highest available resolution for most displays and content
Conclusion
In conclusion, 1280-720 is a high-definition resolution with an aspect ratio of 16:9, commonly used in modern digital media. It offers a good balance between image quality and file size, making it suitable for a wide range of applications.
