VFX supervision with The Mill lasted 2 days of filming in collaboration with Lacus Post. We had to create sequences containing crowd integration, clean plate, and photogrammetry. We had to stage intense shots of people to develop the crowd for post-production. We use a crane to move everything equally to have an exact time.
After we got that calibrated, we started to position each actor in different places to give imagination to the crowd around. But this complicates some shots because we had to do clean plate photography and some HDRI for the CGI integration.
Communication between "The Mill" and VFX producer Brad Martin was a long journey to keep every second as clean as possible and well done as the client wanted. When they were on set all the time. Sometimes, it was necessary to run to the client to explain and then return. It was a good walk with an excellent result at the end.
