Hi!! Does anyone know where the extra scenes from the director's cuts are? thanks!!

it's too early for director's cut. They have not even released Scarlet Heart Ryeo director's cut. 
@makeuptemple thanks! but I refer to episodes 1 and 2, which were repeated with longer duration.
don't know really i watch it on viki 
Kar - someone posted a few links (to YouTube - if I'm remembering correctly) of the extra scenes in the comments.  They've probably been pushed back several pages by now, but it shouldn't take too long to find them.  Or you could just try doing a Google search (in the Video tab) or a direct search in YouTube.  :)
@Neyjour   Thank you very much!!!  I had not found it yet!
You're welcome! :)
