1. A method of encoding a picture of a video sequence, the method being performed by at least one processor and the method comprising:
selecting a candidate resolution among a plurality of candidate resolutions;
resampling a sample of a group of samples based on an output resolution and the selected candidate resolution;
encoding an index in a transient header structure applicable to the group of samples, the index indicating the candidate resolution among the plurality of candidate resolutions;
performing prediction using the resampled sample; and
encoding meta-information associated with previously encoded parts of the picture of the video sequence for a decoder to predict using the resampled sample.
