Method and device for motion vector estimation in video transcoding using full-resolution residuals |
| 摘要 |
A transcoder and method of transcoding in which inter-prediction frames of a downsampled video are encoded using downsampled full-resolution residuals in the rate-distortion analysis used to locate a motion vector for a given partition in the downsampled video.
