An apparatus with a corresponding method and computer program product are provided. The apparatus includes at least one processor; and at least one non-transitory memory including computer program code: wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform the steps (1600) of train or finetune at least one neural network (NN) based at least on a temporal persistence scope; and encode or decode one or more media frames elements based at least on the trained or finetuned at least one neural network. A further apparatus with a corresponding method and computer program product are provided. The further apparatus configured to carry out the steps (1700) of receive a weight-update prediction error from an encoder-side, predict a weight-update based on one or more reference weight updates, and a prediction function or algorithm, and reconstruct a weight update by combining the predicted weight-update and the prediction error.
