VMAF is used by Netflix to tune their encoding and streaming algorithms, and to quality-control all streamed content. [19] [20] It is also being used by other technology companies like Bitmovin [21] and has been integrated into software such as FFmpeg. An objective model should only be used in the context that it was developed for.
Furthermore, Netflix adapts its content to the quality of the network. This is achieved by sending three copies of each title, each at a different quality level, to its servers. For example, if a user's ISP is overwhelmed or the Internet connection is poor, the system can select a lower- bitrate version of the title.
The metric is based on initial work from the group of Professor C.-C. Jay Kuo at the University of Southern California. [1] [2] [3] Here, the applicability of fusion of different video quality metrics using support vector machines (SVM) has been investigated, leading to a "FVQA (Fusion-based Video Quality Assessment) Index" that has been shown to outperform existing image quality metrics on a ...
“In a streaming world, engagement is the north star and direct-to-Netflix feature films are driving an absurd level of engagement,” the LightShed analysts Rich Greenfield, Brandon Ross and ...
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 2018, “Saturday Night Live” captured the public perception of Netflix as a ceaseless river of content. In a satiric ad, the late-night program hawked the streaming service as an “endless ...
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
