Comment (by Cigaes):

 I can not observe your files, I can only assume that they start at the
 same instant.

 As for the recording from the cameras, this depends on the cameras
 themselves on top of the probings performed by ffmpeg. You can try to see
 the delay when you run ffmpeg to read from a single camera, between the
 instant you validate the command and the instant it starts printing
 progress.
