How to replace character (string) in batch?

[m0ck]

Hello.
I have mp4 files with such filename pattern.

"my video - season 1 - episode 01.mp4"
"my video - season 1 - episode 02.mp4"
"my video - season 1 - episode 03.mp4"
"my video - season 1 - episode 04.mp4"

I want them to look like this:

"my video - episode 001.mp4"

So I need to get rid of "season 1" and replace "01" with "001" and so on 002, 003 etc

How do I do that?

Does it have to be batch?
If not, you can use bulk rename utility
