macOS Help with AppleScript

[Hafnium]

Hey MacRumors,

I need help with an AppleScript application.
I hope it is fairly easy to made, but I don't have much/any experience in AppleScript, so I am here to ask you guys for some help

The application:

1. Go to an address (http://example.com/videos/1337.mp4).
2. Download the .mp4 video automatically.
3. Place the video to a specific folder or just the regular "Downloads".
4. Raise the number before .mp4 by one (http://example.com/videos/1338.mp4).
5. Jump back to step 2.

I really hope some have some spare time to "develop" this application, or can redirect me to another site

Thanks in advance!


P.S. If you want me to make a little more clear what I am looking for, please comment.
