same video with different checksums on downloads

[kenny1999]

hi i am attempting to download the same videos from a website using FireFox addon for three times. It's Mp4 files. Interesting is that the three files have the same size, length, resolution (of course) but they have different checksums.

There are no corruption during the downloads.

Does anyone know why Thanks
