Suggestions for marks on set
 

I will shoot a comercial and I will have to put marks on set to track them on post, and later composite with 3D, How is the best way on putting them to make work easier on post.

Haré un comercial el fin de semana y tendré que poner marcas para después trackearlas y mezclaras con 3D. Cómo es la manera correcta y eficiente de ponerlas para facilitar el trabajo.

Thank you

small spots or crosses on the walls using green (or some color that is complimentary to the background color) masking tape the painting stuff will come off without damaging (hopefully) the wall coverings. Works like a champ and is easy to comp out in post as well.

Thanks for your answer, I am not using green screen it will be on set, to put 3D figures, so I will put spots, thanks!

Four spots on the background, and four spots on the floor. You'll need multiple points of reference to get a clean 3-d motion track.
