Cinematic J shows you the most common ways on How to Set Marks for Actors. From using a "T" Shape mark , Toe Mark, Box Mark, Double Toe Box mark... you can choose what works better for you and your actors. Using Marks for actors may seem like a waste a time, but it will actually save you time making sure the actors hit their mark every take. Learning how to hit marks accurately and seamlessly is a vital component of good technique and something all actors must master. The only time Cinematic J doesn't use marks to mark the actors position is on wide shots, instead he asks them to find references within the set props.
