After individual meeting with Paul, I got few important points:
-no subtitle, no one cares on the subtitle and if have the subtitle, audience will more focus on that, not on shoot. Also, audience can understand the story you want to telling, it doesn’t matter has the subtitle or not
-background music, can’t uses any music appeared before in any filmed. It’s about the copyright, and still, if uses a music audience heard before, they will focus on that, not 100% status focus on the scene
-continuity, camera operator needs stop recording after director said ‘cut’ (needs few seconds, then stop) , because the continuity will get more smooth and not strange, and convenient to edit.
-color, the whole scene need in one same color, can not be one shot dark, or one shot bright, it will looks uncomfortable to audience
