26 "## Mirelo Text → SFX — Prompt Guide (sfx-2.0)\n\nGenerate SFX from text. The **prompt is required**. No video — content and length come from your prompt + duration.\n\n## Formula\n\nOne short line that names the **sound**, not a story:\n\n**Source + material/surface + space/distance + intensity** \n(optional: rhythm, layers, mic distance)\n\n| Part | Examples |\n| --- | --- |\n| Source | rain, footsteps, hammer, door latch, whoosh, sizzle |\n| Material | tin roof, wet concrete, wood floor, leather, gravel |\n| Space | close mic, distant, small room, outdoors, large hall |\n| Intensity | soft, heavy, sharp, muted, ringing |\n\n## Good prompts\n\n- `Heavy rain on a tin roof with distant thunder`\n- `Soft footsteps on wood floor in a small quiet room`\n- `Sharp knife chop on a wooden cutting board, close mic`\n- `Car engine idle then short acceleration whoosh, outdoors`\n- `Ceramic cup clink on saucer, soft café ambience underneath`\n- `Metal door slam in a concrete hallway with short echo`\n- `Crackling campfire with occasional wood pop, outdoors at night`\n\n## Weak → better\n\n| Weak | Better |\n| --- | --- |\n| `epic cinematic vibe` | `Deep low whoosh then heavy impact on metal, large hall` |\n| `scary atmosphere` | `Distant creaking wood floorboards, soft wind under a door` |\n| `a man walks into a bar…` | `Bar door open, footsteps on wood, glass clink on counter` |\n| `upbeat music` | Wrong product — or `crowd chatter and glass clinks, no music` |\n\n## Negative prompt (optional)\n\nComma-separated leave-outs. Experimental / often weak on Text→SFX — use as a nudge:\n\n`music, speech, wind, birds, crowd`\n\nExample: prompt `Heavy rain on a metal roof` · negative `music, speech, thunder`\n\n## Tips\n\n1. Concrete nouns you can hear beat abstract mood words.\n2. One main event per prompt; add layers only if needed (`…, soft ambience underneath`).\n3. Prefer one clear line over a paragraph.\n4. Match **duration** to the event (a hit ≠ 30 s of rain).\n5. Run **2–4 variants** and pick by ear; change one dimension at a time when iterating.\n\n## Paste-ready template note\n\n> Describe the *sound*, not the story. Name source, material/surface, space/distance, and intensity in one short line. \n> Example: `Heavy rain on a tin roof with distant thunder`. \n> Optional negative: `music, speech, wind`.\n"
