AWS has made its bandwidth reduction filtering for the AVC and HEVC encoders generally available in AWS Elemental MediaConvert.
The bandwidth reduction filter is a perceptual input preprocessing filter which removes temporal noise from video sources while minimising impact on visual quality, said the company.
It uses human vision system models to reduce imperceptible signals and temporal noise, which often originate from camera sensors, added AWS.
The release means that MediaConvert customers have more options to improve outputs from bitrate-constrained, low-, medium-, and high-fidelity video sources. Used in conjunction with Quality-Defined Variable Bitrate (QVBR) transcodes, the filter is designed to reduce video bitrate without impacting video quality, said AWS.
It can also be used with constant bitrate modes to increase perceived video quality, and is said to be especially relevant for user-generated content captured on mobile devices.
