Everyone else needs two documents: a visa to enter, and a permit to work. Which ones depend on how long they stay.
For a stay up to 90 days, that's a short stay Schengen visa, if their nationality needs one, plus a work permit called a TWV, issued by the Dutch employment agency UWV.
For a stay of 90 days or more, it's an authorisation for temporary stay, known as an MVV, together with a single permit that combines residence and work in one document, the GVVA.
The Schengen short stay is capped at 90 days in any 180 day period, counted across the whole Schengen area. Longer or back to back shoots need the long stay route.
