I was planning to change some commits' usernames and emails in git log. Following this answer, it changes all commits' username and emails, while I only want to modify certain commits. I am wondering how can I revert this change?

Can you detail certain commits ? Are we speaking about a couple or a long list ? – Ôrel Mar 23 '23 at 15:17

git filter-branch has helpfully made a backup of the references that it has rewritten in the refs/original hierarchy.
Say, you have a branch main (that HEAD was pointing to before the operation). The full name is actually refs/heads/main. You will now find the backup under refs/original/refs/heads/main. To undo the branch you can simply do this:
git branch -f main refs/original/refs/heads/main

If you only ran git filter-branch once on your branch, you can reset it to its original head:
git reset refs/original/refs/heads/<branchname>
