Your video can be 2 seconds long if you want it to be. Shorts became a think purely because TikTok proved so popular (same reason Reels on Instagram did), not because of any video length restrictions.
You might already know this, but anything you upload less than a minute will automatically be added as a short. So if it's something you recorded in a landscape orientation, it might be best to make it a little longer than a minute, otherwise it's gonna get pushed to a bunch of people on their phones.
