In that case it looks like your installation went wrong, or something failed when Shotcut started up. (have a look at the application log menu: View -> Application Log, it lists all the filters that are loaded).
You might want to try re-installing Shotcut and trying again.
Thank you so much for your replies . It’s solved , I just changed the language . I used to work with it in French , I changed it to English and I found the filter .
