The stock video editor is not included out of the box. You should be able to download it from the screen you posted a shot of but make sure:
You have an account with Samsung Apps.
You are signed into your account with Samsung Apps (on your phone). You can get to Samsung apps by going to the APK shortcut in the app tray on your phone.
Your "Samsung Push" app is up to date. (Not sure if this is a must, but it can"t hurt)
The app is simply called "Video editor" and it is located in the "Entertainment" section.
It will be nearly 115 MBs.
You can also go to Samsung Apps on your PC and navigate to the Editor, but I am not sure if Samsung Apps works like the play store or not. You might need to do it from you phone.
