Let’s say I have a 5s video with resolution 1920x1080. In that video it shows someone walking from the left of the video and at the end he arrived at the right side of the video. Basically at the beginning he’s somewhere between the 0-384 horizontal pixel position, at the 1st second he’s between the 384-768 position, at 2nd second he’s between 768-1152 position, and so on. What I want to do is to focus on him only with a resolution of 540x1080 (yes, vertical). The other unfocused area will be just black bars. How do I go about achieving this?
Sorry I don’t even know what to search for when looking for sample video online to work on or even the name of the filters or what is it I’m trying to do is called (don’t think it’s motion tracking but I’m not sure). If anyone can help me find the tutorial of something remotely similar to what I’m trying to achieve that’ll be good enough. Thank you.
