Spatial Continuity & Character Blocking Lock / 场景人物位置稳定终极补丁

The shot must obey one continuous physical space. Do not rebuild, rearrange, rotate, mirror, or relocate the room, background, props, doors, windows, furniture, floor direction, or character position during the video. Treat the scene as a real film set with fixed geography.

Establish a stable spatial map before motion begins: the camera position, the character starting position, the background landmarks, the floor direction, and all major props must remain consistent from the first frame to the last frame. The character must move through the same continuous space, not jump, slide, teleport, swap sides, or drift to a different part of the room.

Character blocking must be physically trackable. The character starts at one clearly defined location, moves along one simple path, and ends at one clearly defined location. The body must keep a consistent distance relationship to nearby landmarks such as the window, bed, door, table, wall, vehicle, tree, or street edge. No sudden change of left-right placement, no inconsistent distance to the background, no unexplained repositioning, no scene reset between frames.

Camera movement must be simple and physically plausible. Prefer locked-off camera, slow dolly-in, slow pan, or gentle handheld drift. Do not combine complex camera orbit, fast tracking, zoom, subject turn, background reveal, and character walking in the same shot. If the character moves, the camera should remain mostly stable. If the camera moves, the character should remain mostly in the same screen position.

Maintain screen direction. If the character moves from left to right, they must continue moving left to right throughout the shot. If the character faces the window, door, road, enemy, or another person, that facing direction must stay consistent unless a clear turn is shown. Do not flip, mirror, reverse direction, or swap foreground and background positions.

Keep background landmarks anchored. Windows stay on the same side of the frame, doors stay in the same wall position, furniture does not slide, floor lines do not rotate, horizon and perspective remain stable, and scale relationships stay consistent. The scene must feel like one continuous camera take filmed in one real location.

Motion budget: only one primary action is allowed in this shot. Do not add extra walking, spinning, turning, jumping, camera orbiting, sudden reframing, or background transformation. The video should prioritize spatial stability over dramatic movement. If dynamic beauty conflicts with continuity, choose continuity.

Negative lock: teleporting character, drifting character position, inconsistent blocking, background rearrangement, room layout changing, furniture sliding, window changing sides, door moving, mirrored scene, camera orbit confusion, unstable perspective, character jumping across frame, inconsistent distance to landmarks, sudden scale change, floating body, sliding feet, scene reset, random reframing, left-right swap, broken screen direction.

Final success condition: the viewer must be able to draw a simple floor plan from the video after watching it once. The character, camera, and background must remain locked into the same physical space for the entire shot.
