So we talked about Wire Removal today in class so I figured I would dig some stuff up to show you. It is really quite simple and is nothing to worry about. the only thing that would make it an issue is if the camera is moving and not locked down.
So if you dont know how something like this is done it is done in Adobe After Effects. In the Effects side panel you can find what is called a simple wire removal. It is a little tricky when you get into the key framing however the entire process can be completed in about a half hour if the shots aren't super long.
Here is a link to a video tutorial on how to use the tool.
