Abstract:
1. A computer-implemented method of determining whether to provide a high quality transcoded version of a source video stored in a video repository, comprising: generating a low-quality transcoded version of the source video; generating a high-quality transcoded version of the source video having higher quality than the low-quality transcoded version; determining a relative quality score that quantifies a difference in quality between the high-quality transcoded version and the low-quality transcoded version; determining a weighting factor as a function of a quality of the source video, the weighting factor configured to limit the relative quality score to an upper bound when the source video is of poor quality; adjusting the relative quality score by applying the weighting factor to the relative quality score; and responsive at least in part to the adjusted relative quality score indicating at least a threshold level of quality, storing the high-quality transcoded version of the video in the video repository.
