Abstract
Embodiments include a computer implemented method and apparatus for normalizing perceptual quality in media compression. In one embodiment, a computer implemented method for normalizing perceptual quality in media compression includes determining a maximum bit rate for a target media file, determining a quality setting for the target media file, and compressing the media file to a bit rate equal to the specific percentage of the maximum bit rate multiplied by the maximum bit rate using the computer. The quality setting is a specific percentage of the maximum bit rate.
Claims20
A computer implemented method for normalizing perceptual quality in media compression, comprising:
- determining a maximum bit rate for a target media file using a computer;
- determining a quality setting for the target media file using the computer, wherein the quality setting is a specific percentage of the maximum bit rate;
- and
- compressing the target media file to a bit rate equal to the specific percentage of the maximum bit rate using the computer.
A computer implemented method for normalizing perceptual quality in media compression, comprising:
- determining a first maximum bit rate for a target media file encoded using a first codec using a computer;
- determining a current bit rate of the target media file using the computer;
- determining a quality level of the target media file by comparing the current bit rate with the maximum bit rate using the computer, where the quality level is a percentage value equal to the current bit rate divided by the first maximum bit rate;
- determining a second maximum bit rate for the target media file as converted using a second codec using the computer;
- and
- converting the target media file into a compressed media file using the second codec with a bit rate setting equal to the second maximum bit rate multiplied by the quality level using the computer.
A non-transitory computer readable storage medium for storing software that, when executed by a computing system, causes a computing system to perform a method that comprises:
- determining a maximum bit rate for a target media file;
- determining a quality setting for the target media file, wherein the quality setting is a specific percentage of the maximum bit rate;
- compressing the target media file to a bit rate equal to the specific percentage of the maximum bit rate multiplied by the maximum bit rate.
An apparatus for normalizing perceptual quality in media compression comprising:
- a media compression module for determining a maximum bit rate for a target media file, determining a quality setting associated with the target media file, wherein the quality setting is a specific percentage of the maximum bit rate and compressing the target media file to a bit rate equal to the specific percentage of the maximum bit rate multiplied by the maximum bit rate.
