I apologize for the delay in responding, and thank you for posting. There are several good storyboard tools today: StudioBinder and Boords for simple frames and shot lists, Storyboarder (free) for quick sketches, and tools like FrameForge for 3D previsualization. Many directors also use photo boards with stand-ins, or AI image tools for rough frames.
The best tool is the one that helps your crew understand the shots quickly. Our Pre-production forum is a good place to compare.
