A 4K Ultra HD DVD is the next-generation optical disc format designed to store and play back video content in ultra-high definition, offering a significantly improved viewing experience compared to standard Blu-ray discs.
Here's a breakdown:
- Resolution: 4K Ultra HD video boasts four times the resolution of standard HD (High Definition), resulting in sharper, more detailed images.
- Color: Ultra HD Blu-rays support a wider color gamut (more colors) and higher bit depths (more shades of each color), leading to richer, more lifelike visuals.
- High Dynamic Range (HDR): HDR enhances the contrast between the brightest and darkest parts of the image, providing greater realism and depth.
- Immersive Audio: Often paired with advanced audio formats like Dolby Atmos or DTS:X, 4K Ultra HD DVDs deliver a multidimensional sound experience that enhances the movie's impact.
