Base64 SHA-512 hash not working as intended

Hello I'm trying to get the Base64 encoded value of a SHA512 hash. I want my output to match the output using this site but I can't seem to get it when I try step by step. For example,

The string admin gives x61Ey612Kl2gpFL56FT9weDnpSo4AV8j8+qx2AuTHdRyY036xxzTTrw10Wq3+4qQyB+XURPWx1ONxp3Y3pB37A== when I use the site above.

When I try it step by step, I use a SHA-512 hash generator on admin which results in C7AD44CBAD762A5DA0A452F9E854FDC1E0E7A52A38015F23F3EAB1D80B931DD472634DFAC71CD34EBC35D16AB7FB8A90C81F975113D6C7538DC69DD8DE9077EC

and then I use a Base64 encoder on that which gives me QzdBRDQ0Q0JBRDc2MkE1REEwQTQ1MkY5RTg1NEZEQzFFMEU3QTUyQTM4MDE1RjIzRjNFQUIxRDgwQjkzMURENDcyNjM0REZBQzcxQ0QzNEVCQzM1RDE2QUI3RkI4QTkwQzgxRjk3NTExM0Q2Qzc1MzhEQzY5REQ4REU5MDc3RUM=

which is different. How do I obtain the first output above?

There's two different transformations in play here: the SHA-512 hash of an input and the Base64 encoding of an input. They can be combined or used alone.

C7AD44CBAD762A5DA0A452F9E854FDC1E0E7A52A38015F23F3EAB1D80B931DD472634DFAC71CD34EBC35D16AB7FB8A90C81F975113D6C7538DC69DD8DE9077EC is the SHA-512 hash of the text admin represented in uppercase hexadecimal.

x61Ey612Kl2gpFL56FT9weDnpSo4AV8j8+qx2AuTHdRyY036xxzTTrw10Wq3+4qQyB+XURPWx1ONxp3Y3pB37A== is the SHA-512 hash of the text admin in encoded with Base64. There was no intermediate transformation to hexadecimal.

In other words, x61Ey612Kl2gpFL56FT9weDnpSo4AV8j8+qx2AuTHdRyY036xxzTTrw10Wq3+4qQyB+XURPWx1ONxp3Y3pB37A== is the Base64 encoding of the hash output bytes, and QzdBRDQ0Q0JBRDc2MkE1REEwQTQ1MkY5RTg1NEZEQzFFMEU3QTUyQTM4MDE1RjIzRjNFQUIxRDgwQjkzMURENDcyNjM0REZBQzcxQ0QzNEVCQzM1RDE2QUI3RkI4QTkwQzgxRjk3NTExM0Q2Qzc1MzhEQzY5REQ4REU5MDc3RUM= is the Base64 encoding of the hash output text (in uppercase hexadecimal).
