Rendering settings
As it needs to be imported into the vfx software, our usual rendering settings and camera settings need to be adjusted.
- The first step is to change the focal length of the camera to the same focal length as when we shot the actual green screen video. After the change the lens needs to be adjusted and then rendered.
- The second step is to change the rendering settings, we use the exr format to export and turn on the depth channel and sRGB channel. This format can be used by effects software to match character movement.
- The exr format, an open standard high dynamic range image format, is widely used in computer graphics for storing image data, but can also store some data required for post-compositional processing.
Rendering process
A portion of the footage was rendered using the learned deadline, and the render farm brought a very big help, with over 50 machines rendering at the same time, the rendering could be done in about an hour.
However, shots containing particles could not be rendered using the render farm and I rendered them using my own computer and learned desktop machines.
