There's finally a Motion Tracker plugin for Adobe Premiere Pro called: "Auto Motion Tracker For Objects". The best part is that it works really well. This is great news for us who can't afford the very expensive complete Adobe Creative Cloud Suite, and therefore haven't been able to use motion tracking for video production (seriously Adobe, at least give us the option to buy a perpetual license)! I can imagine this also being great news for people who want to not rely on the buggy Adobe Dynamic Link and prefer to do everything directly inside their NLE. Please note that I'm not affiliated with the creators of this plugin, I just wanted to share this great news!
This plugin appears to be available on ToolFarm and on the aescripts website.
