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 in the neural network post-filter characteristics message, wherein the first syntax element is a 16-bit unsigned integer and indicates a purpose of a neural network post-filter, and the first syntax element equal to 0 indicates the neural network post-filter may be used as determined by an application; and
parsing a second syntax element in the neural network post-filter characteristics message, based on a condition that a value of the first syntax element is equal to 0, wherein the second syntax element is a string and specifies a tag universal resource identifier identifying the application determined purpose of the neural network post-filter.
