For the target video, at 0.00 seconds into the target video, <Picture 1> (from [Shot 1]) is fully referenced.

integrated_multimodal_description: [Shot 1] Live-action, cinematic, a close-up shot frames the person shown in <Picture 1>, maintaining the person’s facial features, hairstyle, makeup, and expression as the person looks directly into the camera with a calm and composed demeanor. At 00:02.000, a hand enters the frame from the right side of the screen and delivers a sharp slap to the person’s left cheek. The person’s head jerks violently to the left due to the impact, hair slightly shifting with the motion. The camera remains static throughout the sequence to emphasize the suddenness and physicality of the action. By 00:03.500, the person rapidly snaps the head back toward the center, eyes wide open, eyebrows sharply furrowed, and mouth slightly parted in shock. The expression transitions into one of disbelief and deep concern, with visible tension in the jaw and forehead muscles. As the scene reaches 00:05.000, the gaze fixes on the lens again but now appears dazed and numb, pupils dilated slightly, lips trembling faintly — capturing the lingering aftermath of the blow. No dialogue or sound effects are produced by the person during this moment.

overall_soundscape: A sharp slap sound echoes clearly through the air, followed by the subtle rustle of fabric as the head moves. Breathing becomes shallow and quickened after the impact. The ambient environment remains quiet, with only faint background hum possibly from indoor appliances.

PS：测试t2va、i2va、ref2va都能增强击打效果，测试使用模型为minimax h3 fi2va_int8_corivrot.safetensors与minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16.safetensors加速lora。lora强度0.50即可，1的话可能会影响人物外貌。也可适当添加对白，镜头拉伸等提示词，基本lora只用于强化击打效果与音效。
