The MediaFork website and forums were moved to HandBrake's, and the next release was officially named HandBrake. [3] On December 24, 2016, after more than 13 years of development, HandBrake 1.0.0 was released. [4] There is another transcoder, called VidCoder, that uses HandBrake as its encoding engine. [6]
They may recompress the video to another format in a process called transcoding, or may simply change the container format without changing the video format. The disadvantages of transcoding are that there is quality loss when transcoding between lossy compression formats, and that the process is highly CPU -intensive.
Nvidia NVENC (short for Nvidia Encoder) [1] is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU to a dedicated part of the GPU. It was introduced with the Kepler -based GeForce 600 series in March 2012 (GT 610, GT620 and GT630 is Fermi Architecture).
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
FFV1 is particularly popular for its performance regarding speed and size, compared to other lossless preservation codecs, such as M-JPEG2000. [ 2 ] [ 3 ] [ 4 ] The encoder and decoder have been part of the free, open-source library libavcodec in the project FFmpeg since June 2003. [ 5 ]
An offline encoder comparison between libvpx, two HEVC encoders and x264 in May 2017 by Jan Ozer of Streaming Media Magazine, with encoding parameters supplied or reviewed by each encoder vendor (Google, MulticoreWare and MainConcept respectively), and using Netflix's VMAF objective metric, concluded that "VP9 and both HEVC codecs produce very ...
In a subjective video codec comparison released in August 2014 by the EPFL, the HM-15.0 HEVC encoder was compared with the VP9 1.2.0–5183 encoder and the JM-18.8 H.264/MPEG-4 AVC encoder. Four 4K resolutions sequences were encoded at five different bit rates with the encoders set to use an intra period of one second.
