Keep one character's face stable across 6 shots
A character's face and features change as shots move between wide, close-up and profile.
Open the case →Shoot two-person dialogue as shot/reverse shot
When two people talk in one frame, identities blur, both mouths move and lip sync fails.
Open the case →Break a fight into 5 single-action shots
Punching, dodging and falling in one continuous shot makes limbs tangle and warp.
Open the case →Build a rainy night that doesn't flicker
Adding rain and neon makes the frame flicker, and both the character and background shimmer.
Open the case →Control a location change with first and last frames
A walk from inside to outside morphs the set midway and doesn't end on the frame you wanted.
Open the case →Emotional close-ups: expression changes, face stays
In close-ups the expression either freezes or changes so much the face changes with it.
Open the case →Phone chat screens: leave them blank, add text in post
Asking the video model to render a chat log gives gibberish or text that changes every frame.
Open the case →Crowd scenes: a clear lead, a crowd that stays put
In crowd scenes the lead's face drifts, extras move chaotically, and duplicate or extra faces pop up.
Open the case →Flashbacks the audience recognises instantly
Flashback shots look the same as present-day shots, so viewers lose the timeline.
Open the case →Keep period costume and hairstyles consistent
A period character's topknot, hairpin, collar and embroidery differ from shot to shot.
