Not really sure if this is a cinematography question, though I wasn't sure where else to post. I have always been curious when watching films either in the theater or on DVD/Blu Ray you sometimes see little white specs/scratches that seem to jump from frame to frame when the screen is black, like on title screens. I can understand why old transfers of movies may have scratches or specs, though why do new movies have this, and why would these specs/scratches or whatever they are get transferred to the DVD or Blu Ray versions of new films?
Thanks.
Thanks.
