[Visual Consistency & Continuity Requirements] Produce a high-end realistic food commercial for 'Hakka Stuffed Bitter Melon', vertical 9:16, warm natural kitchen lighting, macro shots of real ingredients, clear details, restrained steam and oil sheen. Use the same set of 8 bitter melon rings throughout the film, each approximately 2.5–3 cm thick with consistent diameter and wall thickness. The bitter melon skin should maintain its natural bumpy texture and must not turn into bell pepper, cucumber, or zucchini rings. The meat filling consists of 30% fat and 70% lean pork with minced shiitake mushrooms, retaining small hand-chopped particles. The raw filling is naturally pink, while the cooked filling is light brown with a golden-seared surface; color changes across stages should match the real cooking process. Each bitter melon ring is filled with meat, slightly plump at both ends, with the melon and filling tightly bonded. When flipping, plating, or picking up, the two move as a single unit; the filling must not fall out or penetrate the melon walls. Consistently use the same wooden cutting board, the same stainless steel mixing bowl, the same black flat-bottom pan, and the same white shallow round plate. Ingredient size, tool colors, and light direction must remain continuous. Do not generate text, subtitles, logos, watermarks, UIs, or voiceovers. If audio is generated, keep only natural sounds of chopping, searing, and boiling; narration and music will be added in post-production. Segment 1: Slicing and Coring Generate 10 seconds, vertical 9:16 realistic food commercial footage for 'Hakka Stuffed Bitter Melon'. 0-3s: Two washed fresh bitter melons on a wooden board, natural emerald green with clear bumps. Fresh pork, shiitake mushrooms, and small amounts of green onion, ginger, and garlic are placed nearby; background is tidy. 3-6s: A chef uses a Chinese cleaver to cut the bitter melon into rounds about 2.5–3 cm thick. The blade makes real contact with the ingredient; cuts are smooth, and rings are thick, not sliced thin. 6-9s: A small spoon rotates along the inner wall of the rings, scooping out the seeds and white pith, gently scraping away residual membrane. The melon wall remains intact and must not be broken or automatically become hollow. 9-10s: Show the selected set of 8 hollow bitter melon rings arranged neatly on a prep tray. The camera zooms in on one, clearly showing the skin, wall, and hollow structure. Use warm side lighting, slow camera pushes, and macro switching. Focus on where the knife and spoon touch the ingredients; avoid motion blur and overexposure. [Avoid] Pepper shapes, cucumber shapes, thin slices, broken rings, residual seeds, auto-hollowing, ingredients appearing out of thin air, finger clipping, subtitles, watermarks. Segment 2: Mixing and Hand-Stuffing Generate 10 seconds, vertical 9:16 continuous production footage using the same 8 rings from the previous segment. 0-2s: The hollow rings on the prep tray enter the foreground, camera slowly pans to a nearby stainless steel bowl. The bowl contains hand-chopped pork filling, shiitake bits, and aromatics; the meat has natural particles, not a smooth paste. 2-4s: Use natural quick cuts to show the addition of soy sauce, oyster sauce, pepper, egg white, and starch, stirring in one direction. The filling gradually binds but small pork particles and dark shiitake bits are still visible. 4-8s: One hand holds a bitter melon ring while the other uses a small spoon to fill it with meat in stages. Fill the bottom first, then press against the inner walls, and finally top off the top. The filling fits tightly against the wall with no large gaps; both ends are slightly plump but not piled into high meatball shapes. 8-10s: Natural edit to the set of 8 already stuffed bitter melon rings. The filling volume is consistent, and the rings maintain their original thickness and diameter. End by moving the tray toward the stove. Alternate between close-ups and overhead shots, focusing on the spoon pressing the meat. Warm soft light, realistic hand movements, ingredient surfaces are not overly glossy. [Avoid] Meat penetrating walls, independent meatballs, hollow filling, overflow, deformed rings, uniform paste, sauce staining everything black, sudden extra rings, deformed fingers, subtitles, watermarks. Segment 3: Searing and Braising Generate 10 seconds, vertical 9:16 searing and braising footage. 0-3s: The same black flat-bottom pan heats up with a thin layer of peanut oil. Place the stuffed bitter melons from the previous segment flat in the pan, meat side down, in a single layer without overlapping. Small oil bubbles and natural searing sounds appear at the contact points. 3-5s: The chef uses a thin spatula to support a bitter melon ring fully from the bottom, slowly flipping it to reveal a golden-brown seared meat surface, then sears the other side. The ring and meat must flip together; the meat cannot be left in the pan while only the ring moves. 5-7s: Add a small amount of water or broth along the edge of the pan, forming a shallow layer that does not submerge the bitter melon. Cover with the same lid. 7-10s: Use natural time jumps to represent the braising process rather than instant cooking. Upon revealing, the bitter melon has turned a soft yellow-green, the wall is soft but not mushy, and the meat is fully cooked, remaining plump with a golden sear. Warm side light, mid-shots transitioning to macro, emphasizing bubbles, the seared surface, and natural steam. Steam should not obscure all ingredients. [Avoid] Boiling in a large pot, deep frying, charred surfaces, mushy melon, thinning rings, meat falling out, raw pink meat, looking raw after braising, pan color changes, quantity changes, subtitles, watermarks. Segment 4: Glazing and Plating Close-up Generate 10 seconds, vertical 9:16 finished commercial shots for a 7-second final edit. 0-3s: Add seasoning and starch water to the remaining pan juices, gently swirling the pan to create a clear, light-brown thin glaze. The glaze lightly coats the ingredients without becoming a thick gel. 3-6s: Use a spatula to support the stuffed melons from the bottom, completing the plating via natural edits. Use the same white shallow round plate; 8 rings arranged in a single layer, seared meat side up, not stacked in a tower. 6-8s: A small spoon evenly drizzles a small amount of thin glaze over the melon and meat, creating a thin luster. Skin texture, cooked meat particles, and shiitake bits remain clearly visible and not covered by thick sauce. 8-10s: A pair of wooden chopsticks gently picks up one whole stuffed bitter melon from the sides. The ring and meat remain bonded; the ingredient has real weight, and a small amount of glaze naturally drips back into the plate. An empty spot remains on the plate and does not auto-refill. The camera slowly zooms in, focusing on the soft yellow-green wall, golden meat, and clear glaze. Soft blurred background, lingering on the lifted final product. [Avoid] Meat falling off, broken rings, crushed meat, tofu texture, thick gel glaze, excessive oil, dark sauce, auto-refilling ingredients, extra garnishes, rice, subtitles, watermarks. Voiceover Style Prompt: Chinese Mandarin food commercial narration, natural and warm voice, clear expression, friendly homey feel. Steady pace, slight pauses at the end of sentences. Emphasize 'first fresh then sweet', 'each one plump', 'tender and juicy', and 'taste of home'. No exaggerated sales pitch, no mechanical word-by-word reading. Common Problem Corrections: Meat falling out: The bitter melon ring and the internal meat filling are tightly bonded, moving as a single food unit. The spatula supports the entire bottom when flipping; the filling must not slide out, fall, or pass through the melon wall when picked up. Bitter melon looks overcooked: The bitter melon is soft and cooked but the wall maintains its full thickness and ring structure. The surface is soft and moist, not collapsed, shattered, or melted. Meat looks like tofu: Cooked meat must have small hand-chopped particles, shiitake bits, and a natural uneven surface; the seared side is golden-brown, not a uniform white, smooth, textureless block or paste. Glaze is too thick: The glaze is a clear, light-brown thin sauce with fluidity, only lightly adhering to the surface; melon skin and meat texture should still be visible, without appearing as a gelatinous thick paste.
