This hardly depends on which 3D method you use. As not all work the same.

I have 3d camera. If I record 3d video and for example I will open this video by Vegas Pro 16 it gives me two video tracks, question is that I can get this two video tracks using ffmpeg

Welcome! Can you share a sample source file or the text mode output of MediaInfo for one of the source files? What ffmpeg commands have you tried so far? What results have you gotten? How have those results differed from your expectations?
