Does compressing and then decompressing a file change its hash?

Let’s say I simply compress a .mp4 video with zip. Then I decompress that file. Does the hash value change at all? Does it become a “new file,” or does it stay the same?

​

I don’t have the fullest understanding for file hashing.

Zip is non destructive, it should stay the same

Since the byes in the vale’s shouldn’t change after decompressing, the hash stays the same ☺️
