ShotAnvil's free update adds new object keying and using position to choose sections of Luma, Chroma or Saturation keys. An example of the object keyer is shown below.
Please note that the object keyer only works on macOS Sonoma 14.1 or later
OBJECT KEYER
The Object Keyer templates use AI to make a best guess of the clearest featured element in the shot. See example.
KEY BY POSITION
The Key By Position templates use a trackable position axis to choose between different sections of a chroma key. See example.
