Paul Martin Smith (Editor) said previz is being overused, films are being greenlit on previz and then people are shooting the previz. Many mentioned the importance of that magic unplanned spark that happens on set and making sure we leave room for happy accidents and deviation from the plan when needed. Smith also expressed the importance of the creative storytelling process needing time. Cutting on set is not creative, it’s checking to see if basics work. The editor needs time to mentally process the footage.
