1. A method of performing neural network filtering for video data, the method comprising:
receiving a neural network post-filter characteristics message;
parsing a first syntax element from the neural network post-filter characteristics message specifying a number of input pictures to be used as input for a neural network post-filter picture interpolation process;
parsing a second syntax element from the neural network post-filter characteristics message having a value specifying a manner in which input pictures are concatenated before being input into the neural network post-filter picture interpolation process; and
concatenating input pictures based on the value of the second syntax element.
