4. Combine shot types with mood descriptors for professional output

Simultaneous Camera Movement

Place multiple instructions in one bracket:

• [左摇,上升] — pan left while rising
• [推进,下摇] — push in while tilting down

Sequential Camera Movement

Place instructions at different points in the prompt:

• "The camera starts with [推进] toward the face, then [拉远] to reveal the full scene"
