To keep up the pace, DVDFab introduces world's 1st 4K UHD copy software ?? DVDFab UHD Copy ?? to copy 4K Ultra HD movies off the original disc, and then save them as lossless or compressed ISO files, or burn them to blank BD50/25 discs. In the process, both the Dolby Vision and the HDR10 video quality can be preserved. As of now, we already support most of the 4K UHD titles. Also, you may need a compatible UHD drive, see our Supported Drive List.
