4K Video Recording refers to a video resolution of approximately 3840 x 2160 pixels, which is four times the resolution of 1080p (1920 x 1080 pixels). This higher resolution provides greater detail and clarity, making it ideal for large screens and professional video production. Many modern devices, including smartphones, cameras, and televisions, support 4K recording and playback. The increased pixel count allows for more vibrant colors and sharper images, enhancing the viewing experience. However, 4K videos require more storage space and higher processing power for editing and playback compared to lower resolutions.
