  • Increased Resolution

    The Blu-ray format supports a resolution of 1920×1080 pixels, a considerable improvement over the 720×480 resolution of standard DVDs. This increased pixel density results in a sharper, more detailed image, allowing viewers to discern finer textures and details in the film’s costumes, sets, and special effects. For example, details in the intricate patterns of wizarding robes or the textures of the forest floor are rendered with greater clarity.

  • Enhanced Color Depth

    Blu-ray supports a wider color gamut compared to DVD, enabling a richer and more nuanced color palette.
