Matchmoving or camera tracking has traditionally been the responsibility of a 3D department or 3D VFX artists. The point of matchmoving is to emulate the real camera move so that we can add to or remove elements from the moving shot. As 2D VFX Compositors we don’t always need to wait for a Matchmove department to pass us the camera they have created in a dedicated matchmoving software like 3D Equalizer. And indeed sometimes there isn’t a Matchmove department or sometimes they are too busy and we need to matchmove ourselves. Luckily we can do that in Nuke as it has a very good Camera Tracker. As 2D VFX Compositing students you should create a camera track whenever you need to do some cleanup or add elements at different levels of a shot. This is even if you are expecting a camera from 3D department as it will give you an opportunity to develop your matchmoving skills. More one knows the better. There are a lot of benefits to Nuke’s Camera Tracker. You can extract individual trackers to use in a 2D Tracker node and also there is an automatic Point Cloud that can aid in positioning of the cards one can project to cleanup patches or new elements for the shot.
