1080p from DVD

    I've noticed that recently in the Direct Download section there are many videos that are 1080p, but they were made from DVD. How is this possible? Is the quality of the video actually better than the original ISO? Many of them are videos that I would download, but their size puts me off. Seems like such large size, would be better served by posting the DVD ISO. Any thoughts?

    There are two things at play here. One - the studios produce normal Standard Definition DVDs for physical disc sales. Nothing more. There are no Blu-ray versions from the big major studios under the DMM umbrella or practically otherwise. Two - these same studios produce these titles in HD for digital sales. So, the HD versions you see are not sourced from the DVD ISO, rather, the DVD is sourced from the HD digital.

    Thanks for your insight Casshern2.
    I thought that in general, HD was 720p.

    HD starts at 720p but includes 1080p which is Full HD (FHD).

    And as a side thought, several DVD players can provide "Movie Magic" using "Up-scaling Software".
    They claim higher than normal resolution.
    I'm not sure I need to see those defects in her bottom..

    Cashern2 ... Thanks for your help in expanding my very deficient technical education.
    WillEater ... I know what you're talking about, but how does this work?
    It's still using a DVD.
    Does the DVD actually contain more resolution info than we normally see?
    Or is it trickery?
    Oh ... and dimples on the butt can be cool.

    It is trickery in that the upscale is basically blowing up the image gracefully. These days they do a better job than years ago, but it certainly doesn't increase the quality. And resolution isn't the kicker, it is the bitrate that determines the quality.
