A method of encoding a video sequence according to a first set of encoding parameters is proposed, comprising the redimensioning of the video sequence, the generation of encoding data of the redimensioned video sequence according to a second set of encoding parameters, the determination of first encoding data of the video sequence by respective scale transposition of encoded data generated for the redimensioned video sequence, the determination, for at least one encoding block of an image of the video sequence, of respective pixel residuals on the basis of predictive-coding data obtained by encoding the redimensioned video sequence, the application of a block transformation to the pixel residuals determined, and the insertion of the transformed pixel residuals and of the first encoding data into a binary encoding stream of the video sequence. |
