How to create a torrent and upload it to the seedbox?

I have a movie that I want to upload to a tracker, but when I create the torrent and upload it to the tracker it does not work, it stays 0.00% up and down

The movie I have in the pc, is not in the seedbox, and my objetive is to create a torrent of the movie and upload it to the seedbox.

I know there is a way to do it, you can upload the file folder to upload (in this case the movie) with Filezilla, adding the folder to the filezilla and upload it to the seedbox as if it were a direct download server

But this takes a lot, so it is not an option, this takes depending on the speed of upload you have (speed of home), and mine is bad, I hope you can help me

I already saw the how to crate a torrent from seedbox guide here in TI, but this guide mentions how to create the torrent from seedbox to seedbox, not from pc to seedbox
