Overview

HEVC, short form for High Efficiency Video Coding, is a video compression standard successor to H.264/MPEG-4 AVC. So HEVC also known as H.265. HEVC is targeted at next-generation HDTV displays and content capture systems which feature progressive scanned frame rates and display resolutions from QVGA (320×240) to 4K UHD 4320p (8192×4320), as well as improved picture quality in terms of noise level, color spaces, and dynamic range. HEVC was designed to substantially improve coding efficiency compared to H.264/MPEG-4 AVC HP, that is to say, to reduce bitrate requirements by half with comparable image quality, at the expense of increased computational complexity. Given the same quality video, HEVC H.265 video can reduce file size of 52% for 480p video, 56% for 720p video, 56% for 720p video, 62% for 1080p video and 64% for 4K UHD video compared to H.264/MPEG-4 AVC.

FLAC is an an open format and royalty-free coding format for lossless compression of digital audio. FLAC is specifically designed for efficient packing of audio data. It is able to reduce the size of audio data by 40–50% by taking advantage of the characteristics of audio. A CUE file can optionally be created when ripping a CD to FLAC including track order and pregap.

Windows Media File can be Windows Media Video File or Windows Media Audio file. Windows Media Video File (WMV) is a file type which can contain video in one of several video compression formats developed by Microsoft. WMV file contains video encoded with one of Microsoft’s Windows Media Video (WMV) proprietary codecs, WMV 7, WMV 8 or WMV 9.

Can QuickTime X Play AVI, WMV, FLV, MKV, DivX in Sierra/El Capitan/Yosemite/Mavericks?

After upgrading to macOS Sierra, El Capitan, Yosemite or Mavericks, the Quick Look function to preview a movie file in thumbnail won’t work any more for files with extension of .avi, .wmv, .flv,. .mkv, .divx. When attempting to preview such movie files with Quick Look, it shows an empty document with zero KB in size. When double-clicking on the movie files, it opens in QuickTime Player X but then immediately converts with conversion process never finished even you wait for 24 hours. Can QuickTime X play AVI, WMV, FLV, MKV, DivX in Sierra/El Capitan/Yosemite/Mavericks?
