Cinematic scene

Create a 15-second polished 3D animated comedy short, cinematic feature-film quality, 16:9 widescreen. Stylish modern café, warm natural lighting, expressive character animation, sophisticated visual humor, precise comedic timing, minimal or no dialogue. The joke must be immediately understandable and completely visual. MAIN CHARACTER: A stylish young woman with expressive facial animation, fashionable casual clothing, sitting alone at a café table with a coffee and smartphone. Original character design. 0–3 seconds: The woman holds her smartphone up and takes a selfie. She looks at the photo. Her expression immediately changes to mild disappointment. Very clear visual storytelling: she wants a better selfie. 3–6 seconds: She adjusts her hair and changes the angle of the phone. Takes another selfie. Looks at it. Still not satisfied. She adjusts her sunglasses, straightens her clothing, moves her coffee cup slightly, and takes another photo. 6–10 seconds: She becomes increasingly serious about getting the perfect photo. She stands up and moves her chair a few centimeters. Tilts her head. Changes the phone angle. Moves her coffee cup again. Takes several more photos in rapid succession. A waiter carrying coffee approaches and has to carefully walk around her while she remains completely focused on her phone. A nearby customer briefly watches her, amused. The woman behaves as if she is conducting an extremely important professional photo shoot. 10–13 seconds: She finally takes one last photo. She looks at the screen. Her face lights up with enormous satisfaction. Perfect. She smiles proudly and relaxes. 13–15 seconds: She begins scrolling through her photos. Her smile slowly disappears. She turns the phone slightly. Reveal clearly: the phone camera has been facing the WRONG DIRECTION the entire time. Her screen shows dozens of beautifully composed photographs of the café wall, ceiling, and background instead of herself. She slowly looks from the phone toward the exact café wall she has photographed repeatedly. A waiter passes behind her and gives her a tiny sympathetic look. She sits completely still in stunned embarrassment. CUT TO BLACK. STYLE: High-end original 3D animation, expressive facial acting, elegant cinematic café environment, subtle exaggerated body language, dry observational comedy, polished materials, beautiful lighting, precise comedic editing. The character's behavior should become increasingly serious while the actual problem remains extremely trivial. No surreal events, no explosions, no random chaos, no slapstick, no complicated dialogue. The audience must understand the joke immediately.

Cinematic scene

Format: 30-second photorealistic handheld phone vlog Setting: The coast of what is now North Carolina, 1585 Audio: Diegetic sound only. No music. Character lock — Vlogger: A 25-year-old fashion icon with a distinctive face and poised presence. Sleek dark hair, sculptural silver earrings, tailored cream jacket, black trousers, striking boots, and a small designer bag. She holds her phone throughout. Keep her face, hair, outfit, and voice consistent across every shot. Her confidence gradually gives way to uncertainty. 00:00–00:05 — Arrival A white glitch tears across her phone camera. She stumbles onto a sandy path beneath tall coastal trees, catches herself, checks her outfit, and looks up. Vlogger: “Wait. Where am I?” 00:05–00:11 — The stares She turns the phone outward. Indigenous people move between timber homes, carrying baskets, tools, and water vessels. Conversations pause as several people notice her unfamiliar clothes and phone. Aware of the attention, she lowers the camera slightly. Vlogger, quietly: “They’re all looking at me.” 00:11–00:17 — Realization She steps aside to let a family pass. The phone briefly hunts for focus between her polished boots and the sandy path. Near the shoreline, she glimpses a small group of English newcomers. Vlogger: “This is… 1585?” 00:17–00:24 — A different perspective From a respectful distance, she films someone weaving, children moving between homes, and people exchanging goods. An older woman meets her gaze. The vlogger stops filming outward and turns the camera toward herself, visibly shaken. Vlogger: “I came here thinking I’d see the past. This is their present.” 00:24–00:30 — Return Light flickers at the edge of the frame. She looks down the path once more as people resume their day, then lifts the phone toward her face. Vlogger: “I need to remember what I actually saw.” The path dissolves into a brief white flicker. Cut to black. Visual and sound direction: Spontaneous handheld phone footage with subtle autofocus hunting and natural exposure shifts. Natural daylight, wind through trees, footsteps on sand, distant voices, and coastal birds. Dialogue is clear and precisely lip-synchronized. Historical and visual constraints: Portray Indigenous people as individuals going about ordinary life, with historically grounded clothing, homes, and objects. No modern streets or buildings, generic “tribal” costumes, ceremonial dress presented as everyday wear, exaggerated reactions, comedy, changing facial features or clothing, distorted hands, on-screen text, captions, logos, subtitles, watermarks, or music. Do not call the location “the USA” in 1585.

Cinematic scene

Create a 15-second original chaotic action-comedy animation, 16:9. A normal adult stands in front of a vending machine, trying to buy a bag of chips. 0–3 seconds: The person inserts money and presses a button. Inside the machine, a bag of chips begins falling. Almost. It becomes stuck halfway between two metal coils. The person stares at it. The snack hangs there motionless. 3–6 seconds: The person taps the glass. Nothing. Taps harder. Nothing. They shake the machine slightly. The snack wiggles. The person's eyes light up. Then the snack stops moving completely. Their confidence disappears. 6–9 seconds: The person launches into a ridiculous recovery operation. They study the machine from multiple angles. Slide across the floor. Climb onto a nearby chair. Attempt impossible rescue maneuvers. The vending machine is filmed like a massive fortress protecting a priceless treasure. 9–12 seconds: A spectacular action sequence unfolds. The person swings from the side of the machine, pulls, pushes, and performs increasingly absurd stunts. Finally the stuck snack breaks free. It flies through the collection slot. The person dives dramatically through the air and catches it with both hands. Total victory. 12–15 seconds: The person proudly examines the recovered snack. Then freezes. It is not the snack they purchased. The original bag is still visibly stuck inside the machine. The person slowly looks from the recovered snack to the original snack. Complete emotional devastation. CUT TO BLACK. High-energy original 3D animated comedy, spectacular action-adventure parody, dynamic camera movement, dramatic low angles, expressive character acting, escalating visual chaos, clear storytelling, precise comedic timing. The vending machine should feel like an impossible obstacle while remaining an ordinary vending machine. No dialogue, no subtitles, no text overlays, no logos, no recognizable brands, no copyrighted characters, no existing franchises, no celebrity likenesses, no gore, no horror.

Cinematic scene

Create a 15-second original chaotic action-comedy animation, 16:9. A normal office meeting is taking place in a quiet conference room. One sharply dressed man sits at the table trying to remain perfectly professional. 0–3 seconds: The man suddenly feels a sneeze coming. His nose twitches. His eyes widen slightly. He immediately realizes what is about to happen. He tries to remain completely still. 3–6 seconds: He pinches his nose. Holds his breath. Closes his eyes. The sneeze keeps building. His cheeks puff slightly. His entire body begins trembling. The people around him slowly notice something is wrong. 6–9 seconds: The sneeze becomes ridiculously powerful. Papers on the table begin fluttering. A coffee cup vibrates. His tie starts blowing backward. His chair slowly slides away from the table. He desperately grips the edge of the table with both hands. His expression says absolute panic while everyone else watches in stunned silence. 9–12 seconds: He finally loses the battle. ACHOO! A huge comedic burst of air launches him backward across the room. Papers explode upward. Chairs roll away. Office supplies fly through the air. He crashes harmlessly into a large stack of empty cardboard boxes. The boxes collapse around him. 12–15 seconds: Complete silence. The room is covered with papers. The man slowly rises from the cardboard boxes. He calmly straightens his jacket and adjusts his tie, trying to recover his dignity. Everyone stares at him. He gives a tiny embarrassed smile. Then his nose twitches again. His eyes widen. CUT TO BLACK. High-energy original 3D animated comedy, spectacular cinematic action, exaggerated but coherent physical comedy, expressive facial animation, dynamic camera movement, dramatic reaction shots, strong escalation, precise comedic timing. The sneeze should build visibly and progressively before the final ridiculous release. The character takes the situation far too seriously. No dialogue, no subtitles, no text overlays, no logos, no recognizable brands, no copyrighted characters, no existing franchises, no celebrity likenesses, no gore, no horror.

Cinematic scene

Create a 15-second extremely funny cinematic 3D animated action comedy, 16:9 widescreen. Cozy realistic living room, polished high-end animation, expressive character acting, dynamic camera movement, rapid physical comedy, exaggerated but readable choreography, strong comedic timing. The entire sequence must revolve around ONE tiny relatable problem: a man drops one potato chip between the cushions of his sofa. MAIN CHARACTER: An ordinary adult man relaxing at home, casually eating chips while watching television. He becomes absurdly determined to retrieve one single chip. 0–3 seconds: The man relaxes on his sofa while eating potato chips. One chip slips from his fingers. It falls directly between the sofa cushions and disappears. He looks down. He casually reaches between the cushions. He can't reach it. 3–6 seconds: He removes one sofa cushion. Nothing. Removes another cushion. Still nothing. He reaches deep between the cushions. His entire arm disappears into the sofa. He struggles to reach the chip. 6–9 seconds: He grabs a small flashlight. He gets down on the floor and shines the flashlight underneath the sofa. Reveal the chip clearly visible underneath, just beyond his fingertips. He stretches toward it. Almost reaches it. The sofa shifts slightly. He slides farther underneath. 9–12 seconds: Now he is awkwardly wedged beneath the sofa, with his legs sticking out. He reaches for a broom and tries to push the chip toward himself. The broom accidentally pushes the chip even FARTHER away. He freezes. His expression changes from mild annoyance to intense determination. He crawls farther underneath. The sofa suddenly begins sliding forward. He grabs the sofa leg. The sofa continues moving. 12–14 seconds: The man finally emerges from underneath while accidentally dragging the entire sofa several feet across the room. The chip shoots out from underneath. He catches it triumphantly. He stands up holding the single chip like a priceless trophy. 14–15 seconds: He proudly eats the chip. CRUNCH. He looks toward the coffee table. Reveal: a large untouched bowl containing dozens of identical potato chips is sitting directly beside him. He looks at the bowl. Looks at the single chip he just fought for. Silence. CUT TO BLACK. STYLE: High-energy original 3D animation, cinematic action-comedy camera language, dynamic tracking shots, quick cuts, expressive facial reactions, exaggerated physical choreography, strong cause and effect. The escalation should become increasingly ridiculous but always remain easy to understand. The audience should clearly see the chip throughout the important moments. No dialogue required. No explosions, weapons, injuries, violence, horror, or random surreal events. Harmless physical comedy only. No copyrighted characters, celebrity likenesses, logos, subtitles, or watermarks.

Cinematic scene

Subject: A young, attractive East Asian female pop idol with long dark hair, wearing a sparkling sheer long-sleeve crop top, a black skirt, and dangling crystal earrings. Her demeanor is energetic, cheerful, and playful. Style: Cinematic backstage vlog style. Cool, polished tones with warm highlights, 35mm film grain, and realistic handheld camera shake. Camera & Framing Lighting: Bright indoor hallway lighting with soft overhead spotlights and warm reflections. Framing: Dynamic first-person (POV) selfie-cam angles, wide tracking shots, and close-ups as she interacts with the environment. Effects: Shallow depth of field and natural motion blur. Audio & Scene Dialogues 00:00 - 00:01: Close-up POV selfie shot of the idol smiling and tossing her hair back in a backstage hallway. Dialogue: "Hey guys, we're backstage right now..." 00:02 - 00:03: Rapid handheld pan down a long corridor with crew members walking in the background. Dialogue: "Look how long this hallway is." 00:04 - 00:05: Pointing at a dressing room door plaque bearing her name. Dialogue: "That's me! That's my name! ("HEER")" 00:06 - 00:06: Wide tracking shot of her walking quickly down the corridor. 00:07 - 00:08: Full-length outfit check in a hallway mirror while adjusting her skirt. Dialogue: "Okay, outfit check. How do I look?" 00:09 - 00:11: Picking up a snack bar from a backstage catering table and taking a bite directly to the camera. Dialogue: "Ooh, snack table. Don't mind if I do." 00:12 - 00:14: Waving goodbye, making a finger heart gesture, and turning to run toward the stage. Dialogue: "Wait, wait, wait! That's my cue. See you guys after the stage!" Realism: Photorealistic 8K rendering with natural fabric movement, accurate skin textures, realistic lighting reflections on clothing and hair, and organic hand-held camera motion.

适用情况

依据公开资料与当前站内设置,说明模型适用的任务及需要注意的限制。

先把目标配音准备好

准备清晰且有权使用的目标人声音频;口型生成后,仍要检查语义、节奏和画面是否协调。

估算依据是目标音频长度

本站会核实音频时长,不能用自行填写的秒数代替;视频长度也不等于用于预扣的音频长度。

能力详解

用目标音频调整视频口型

以已有视频为基础,用目标音频驱动嘴部动作;画面、表情和原动作的保留情况需逐段检查。

轻量模式的循环选择

音频较长时可选择循环视频;反向循环须先开启循环对齐。关闭对齐后,尤其要检查短视频的成片时长与重复情况。

基础模式的场景检测

基础模式可开启场景检测与说话人识别;轻量模式不能开启此项。

适合做什么

尝试多语言口播

为已有讲解视频准备另一语言的目标音频,尝试同步口型,再人工检查音画与口型节奏。

更新课程讲解音轨

用新讲解音频处理原视频,检查讲师动作、表情与新内容是否协调后,再决定能否采用。

试做营销口播修改

已有画面适合复用时,可尝试替换目标音频;修改后的效果仍可能需要剪辑或补拍。

提示词技巧

尽量使用清晰纯人声

准备素材时减少背景音乐、混响和多人重叠说话;人声分离选项也不能代替最终听音检查。

让嘴部清楚可见

轻量模式可先选择单人正面、遮挡较少的视频;生成后检查嘴部、表情与目标音频的配合。

先确认模式,再调循环和起点

视频起点只接受非负秒数,还需确认起点与原视频内容是否合适。基础模式请将循环对齐、反向循环和起点保留默认;轻量模式开启反向循环前,须先开启循环对齐。

为什么选它

可用已有视频承接新的目标人声音频。
预扣可按目标音频时长估算,结算条件可提前查看。
2 种模式分别面向正面和较复杂的单人场景。
提交前检查素材要求及音频时长。

使用前要知道

归档资料将轻量和基础模式都定位于单人场景,不能据此确认多人同时说话的效果。
必须同时提供视频和独立的目标音频文件。
本站视频文件上限为 95 MiB。
口型错位、表情、音画节奏和语义自然度仍需人工检查。
