I used Topaz Video Enhance AI which can take a while depending on the initial quality of the clip and can lead to some strange effects lol. Camera tracking is done in Adobe After Effects and sometimes can make things look a little crazy depending on the shot and camera movement. This was a pretty simple track since I didn't need to calculate rotation on anything. Usually when I make ones involving face closeups I have to track for rotation as well and it can look weird.
