7 Rules of Matchmove (Week 1)

Matchmoving is a cinematic digital technique that allows the insertion of computer graphics and animation into a live-action video with correct position, scale, orientation and motion relative to the photographed objects in the shot.


It works by tracking the movement of the camera and the contrasting colours in it, that includes corners and distinct spots.


The seven rules of matchmoving are as follows:


1. There has to be something to track

2. Tracking things have to be done at different depths - perspective will become clearer

3. Have to get helper frames - take at least 10 different pictures from different angles

4. A little bit of foreground makes a better matchmove

5. Cannot track anything that moves

6. Cannot have too much foreground - markers will be lost if there's too much

7. Have to get a scale reference - measure distance between two points that is going to be tracked
