I have unchecked "show all filename extensions" on Finder's advanced preferences window but all my files still show extensions like jpeg and mp4. How can I make them go away?

I found a partial solution. While it does not solve the underlying problem of the files being created with extensions showing, the below will remove extensions from existing files in large batches.
1. Go to All My Files in Finder.
2. Search for ".pdf" (or another extension you wish to remove).
3. Select all files.
4. Right click and select Rename...items.
5. Enter ".pdf" in the Find box.
6. Click rename without entering anything in the Replace with box.
7. Repeat for other extensions.
Then do I have to individually click on all my photos, songs and videos to hide their extensions? That seems really impractical. Is there an option to hide extensions for let's say all mp4 files so that I can at least hide them one by one for each file format?
Disabling that option hides extensions only for files which have do not have an individual setting configured to "Show".

I think extensions creat an unnecessary crowd. I'd only like to see the file names. Such a shame that there is no easy way to do it, as all my new files are created with extensions for some reason and I don't have the energy/tiime to manually hide extensions on my old files.
This didn't work. After I did it, I still see extensions on files.
Apple menu->ForceQuit-> select Finder and "relaunch Finder".
YES, thanks for pointing out, Lex
I don't know a method for changing all of them en masse.
Can I ask why you want don't want to see them?
There is very probably a Terminal command to hide the extensions, but I don't know it.
File extensions won't stop showing
