MGCOOL has finally taken the
wraps off its new Explorer 2 and announced that the Explorer 2 will support 4K
H.265/HEVC recording. With the smaller size and higher quality, H.265/HEVC
codec has become more and more popular codec used by more camcorder brands,
like GoPro Hero 5.
What is H.265 codec? H.265, whose full name is High
Efficiency Video Coding, is a new video coding standard that specifies how to
decode video, which is the successor to Advanced Video Coding (AVC), also known
as H.264.
It is developed by the Joint Collaborative Team on
Video Coding (JCT-VC), and the first version of the standard was completed,
approved, and published in 2013. The second version was completed and approved
in 2014 and published in early 2015, and includes format range extensions,
scalable coding extensions (SHVC), and multi-view extensions (MV-HEVC).
As data-intensive as HD is, 4K is even worse.HEVC’s
main advantage over H.264/AVC is that it offers roughly double the compression
ratio for the similar quality, though compression efficiency results vary
depending on the type of content and the encoder settings, at typical consumer
video distribution bit rates. This means that a video file encoded with HEVC
can occupy half the storage space of its H.264 equivalent with no noticeable
change in quality.
When compressed to the same file size or
bit rate as H.264, H.265 delivers significantly better visual quality. Sounds
pretty good. Without doubt, Explorer 2 will offer its users with better experience by
reducing file size with original quality being remained.
