    关于各种格式的区别:

  • REMUX:无损的提取出原盘的原始视频数据和音频数据,去除菜单﹑花絮和多余的音轨,封装到TS格式中,可能采用DVD提取的国粤语和其他音轨,画质与原盘没有差别
  • 蓝光RiP:对蓝光Blu-ray等介质的原始视频进行重编码,视频形式采用X264编码,音频采用原片音轨转码的AC3或DTS
  • WEB-DL:来源是各大视频网站,质量要比HDTV好,相比HDTV,无水印,无台标logo,无插播广告,所以无任何剪切较完整。
  • HDTV的片源是录制于高清电视,基本都有台标

When several of us reviewers at Blu-ray.com transitioned to 4K equipment, those of us in ostensibly smaller markets found it rather difficult to find qualified, trained calibrators able to handle this "newfangled" technology. If I'm remembering correctly, even some reviewers in pretty darned huge markets like New York City had to do at least a little finagling to finally get their equipment at optimal video and audio levels. Spears and Munsil have provided a "do it yourself" option with this disc, though my hunch is even some ardent videophiles are going to want a little expert advice as they navigate a rather impressive array of calibration options on this disc.

Please note that this image is not taken from the Blu-ray disc and is not representative of the Blu-ray video quality.


The disc has an impressive number of calibration options on it, with each of the following Menus typically leading to elaborate Submenus, though many of those simply start a slideshow at a different point (see the last "screenshot" accompanying this review for one of the Submenu options):
Configuration
Video Setup
A/V Sync
Advanced Video
Video Processing
Windows
SDR BT.709
Demo Material
The disc offers all of its wide array of calibration patterns in 600, 1000, 2000, 4000 and 10,000 cd/m2 versions, and there are some manifest differences with different luminances, especially in calibration patterns helping to delineate black levels and grayscale. The configuration menu also allows for choices in HDR Gamut and Audio Codec. The demo material is advertised as having been finished in 8K HDR, and it is provided in both HDR and SDR for comparison's sake.
