If I have a video of a face moving around, and I want to change the colour of the eyes in the video for example, how do I do that? I don't need specifics, just point me in the right direction, like which software is designed to do things like this? What is this process called? Do I literally go through frame by frame and make the changes? Is this a task that is mainly done programmatically?
I just want to know where to start learning. I'm very technical but I don't have experience with video editing, and don't know where to start googling even. Thanks!
