We are entering the exciting world of virtual production! Virtual production involves using an LED wall instead of a traditional green screen or cyc wall. Instead of adding backgrounds in post production you display the enviroment on the LED wall and film the actor infront of it in real time. This is called In Camera VFX (INCVFX). There is a huge potential for cost savings in post production by having ICVFX as you film.
Using photogrammetry, we scan enviroments and re-create them digitally. We have developed a pipeline for photogrammetry that has been working well for us. Everything from taking pictures of the enviroment and making 3D models out of them we have sped up our workflow from camera pictures to film ready assests. We settled on using Reality Capture for building the model and Blender for model cleanup. We then use the photo realistic scans in the Unreal Engine (UE4) which then displays on the LED wall. There are other programs you can use, but these just happen to be some of the programs we are using.
