|\n|---------|--------------|---------|\n| `[VISUAL]` | Shot type, subject appearance, clothing, setting, lighting, actions | *A medium shot of a woman with short black hair wearing a white blouse, standing in a modern kitchen with warm lighting and speaking calmly.* |\n| `[SPEECH]` | The literal words to be spoken | *Hello everyone, welcome to our channel.* |\n| `[SOUNDS]` | Speaker vocal qualities (volume, tone, distance from mic) and background sounds | *The speaker has a calm, conversational tone at moderate volume, close to the microphone. Soft birds chirping in the background.* |\n\n**Full example:**\n\n```\n[VISUAL]: A medium shot features a young man with curly brown hair and light blue eyes, sitting on a beige couch. He is wearing a light blue shirt and a red patterned tie. His mouth is slightly open as he speaks. In the background, there is a blurry room with warm lighting.\n[SPEECH]: We are proud to introduce ID-LoRA.\n[SOUNDS]: The speaker has a moderate volume and a conversational tone, sounding engaged and natural. They are close to the microphone. Light, instrumental background music plays softly, creating a calm atmosphere.\n```\n\n**Tips:**\n- Be descriptive in `[VISUAL]` β€” shot type, colors, clothing, and background details all help, mention that the person is speaking to avoid voice-overs.\n- `[SPEECH]` should contain the exact transcript, not a summary.\n- `[SOUNDS]` controls both the speaking style (tone, volume, mic proximity) and ambient sounds (music, nature, room noise).
