Nowadays, it is common for us to run into 4K screen and 4K Ultra high-definition (UHD) video. 4K UHD video is famous for its superb high-definition image and for audio input at the same time.

If you have some 4K UHD video files and would like to compress and convert 4K to 1080P HD, here is the right place for you to get to.

Part 1: Warming up Before Converting 4K to 1080P


What is 4K UHD video?

In August 2012, the Consumer Electronics Association introduced the term Ultra High Definition, partly defined as resolutions of “at least 3,840×2,160 pixels”. The idea was to replace the term 4K. The CEA’s name lasted less than a day, as Sony then announced it was going to call the technology “4K Ultra High Definition”. This is the term now used by most other TV manufacturers too. In practice, you will often see UHD used interchangeably with 4K, whether describing TVs, source devices, accessories or content.


What is 1080P HD video?

1080p (also known as Full HD or FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan, as opposed to interlaced, as is the case with the 1080i display standard. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 1920×1080 (2.1 megapixel) often marketed as Full HD.

Why do people convert 4K to 1080P?


  1. Fail to play 4K video on media player (VLC, QuickTime, Windows Media Player, KMPlayer, GoMPlayer ) or handheld devices (Samsung, HTC, Sony, iPhone iPad), for the majority of media players and media devices work well with 1080P (1920 x 1080) rather than the newcomer 4K (3840 x 2160).
    Note: Even if iPhone 6/6s is claimed with ability of 4K video playback, an extra app/converter is still in demand since iTunes will not sync 4K videos.
  2. Unable to edit 4K video in video editing software like iMovie, Final Cut Pro, Windows Movie Maker, Sony Vegas, Adobe Premiere Pro, Cyberlink Powerdirector, etc.
  3. Hard to upload 4K video to YouTube, Facebook or other video sharing sites on account of the much bigger file size (the data amount of each frame is as big as 50MB) and high definition (Instagram, vevo, yahoo, Myspace, ehow, etc. do not support 4K video).
