How to shoot a video to separate the person from the background?

Question

Video

The task is to make something like animated avatars of employees.
It is necessary to separate the moving image from the background accordingly.
Of course, a green background immediately comes to mind, the light is there, that's all. But maybe modern software makes it easier to solve these issues?

Answer 1

There are many almost standard solutions (for example, in MacOS) that "replace" the background. True, not very high quality)

Answer 2

Chromakey is the most reliable option.
Although there are all sorts of end-user solutions like FaceRig .

Answer 3

In "CamtasiaStudio -8" there is such a function to remove the background and not necessarily green. The main thing is that the background color is not present on the object (person), otherwise it will also be deleted.
