MD5 of the same files are different

Post by TheBombEmperor61 »

I ripped a video 3 times from a disc and found that the MD5 sum was different for all three.

Is this expected and what is the explanation?

Yes, it's expected. Among other things, there's a unique text header in the metadata of all MKVs. Use MediaInfo to poke around.

Code: Select all

General
Unique ID                                : 261860272940468430999439405479738788489 (0xC500743F4077B1B7804D3A3D082CCA89)
