Sora 2 最佳提示:2025 年 AI 视频生成完整指南 - Cursor IDE 博客 --- Sora 2 Best Prompts Complete Guide to AI Video Generation in 2025 - Cursor IDE 博客 --知识铺
什么是 Sora 2 以及它为何重要
OpenAI 于 2025 年 9 月 30 日发布了 Sora 2,这标志着公司所说的“视频生成的 GPT-3.5 时刻”。这一代 AI 视频模型将文本提示转换为 10 秒 720p 视频,具有同步音频、逼真的物理建模和前所未有的创意控制。对于任何探索最佳 Sora 2 提示的人来说,理解这个工具的功能意味着平庸的输出和专业质量 AI 视频之间的区别。
Sora 2 可以生成以前视频 AI 模型发现特别困难或不可能的内容:奥运级别的体操动作,具有准确的身体力学;在冲浪板上翻转时正确模拟浮力和刚性;以及三周跳,其中一只猫在滑冰者的头上保持逼真的平衡。研究表明,这些不是花哨的演示,而是模型改进的内部物理理解能力的展示。
突破在于三个核心创新。首先,Sora 2 生成同步音频——与匹配的唇部动作、复杂的背景音效和逼真的音效——所有这些都原生地与视觉效果对齐。其次,该模型采用增强的物理精度,因此当篮球运动员投篮不中时,球会以逼真的动作反弹到篮板上,而不是变形或消失。第三,新的“客串”功能允许 AI 根据参考视频准确呈现你的外观和声音,将你插入任何生成的环境中。
访问需要 ChatGPT Pro 订阅(每月 200 美元)并且仅限于美国和加拿大用户。10 秒的最大时长和 720p 的分辨率代表了技术限制,但质量和可控性超过了所有之前的版本。
特性 | Sora 1 | Sora 2 | 改进 |
---|---|---|---|
音频 | 无 | 同步音频(对话、音效、环境音) | 革命性的 |
物理 | 基础动作 | 逼真的动态效果(体操、浮力、碰撞) | 显著提升 |
最大长度 | 60秒 | 10 秒(720p) | 画质降低但更高 |
控制 | steerability 有限 | 增强的镜头级控制,客串 | 更加精确 |
对于寻求 Sora 2 提示工程大师级的创作者,本指南提供了 50 多个经过测试的提示,系统化的音频和物理控制,故障排除策略,以及包括通过 API 路由访问中国的地理限制解决方案 。
核心功能和特性
音频同步
Sora 2 代表了 OpenAI 首个具有原生音频生成的视频模型。该系统创建复杂的背景音效、与唇部动作匹配的角色对话和逼真的音效,所有这些都与视觉效果完美同步。根据官方发布的信息,创作者可以指定带有时间标记的对话块,如“两行对话,唇部同步”,以利用这一功能。
音频引擎对节奏提示做出反应,例如“在笑点之前暂停”或“随着摄像机靠近,脚步声逐渐增强”,将音频时刻与视觉动态对齐。研究表明,用户可以使用诸如“室内音调,柔和的 HVAC 嗡嗡声”或“海岸线波浪,中距离人群”等描述词来描述环境质感,然后将视觉元素锚定到这些声音提示上。这种双向音频-视觉连接使 AI 生成内容中的沉浸感达到了前所未有的水平。
物理建模
Sora 2 通过复杂的运动建模展示了物理真实感。该系统能够准确模拟体操动作、模拟浮力和刚度的冲浪板后空翻,以及猫在完成三周跳时保持的逼真平衡。这些例子反映了模型对内部物理理解的提升,而非后期处理技巧。
物理引擎处理逼真的失效建模。在一个测试中,一名篮球运动员投篮未中,球反弹到篮板上,轨迹和旋转都准确无误。另一个提示生成了一个站在两匹马上的场景,最终“马儿摔倒得很重”,这表明模型理解了重量分布、平衡和不稳定位置的影响。
头像和个性化
头像功能可以观察一个人的视频,并将他们以准确的外观和声音插入到 Sora 生成的任何环境中。这使您能够创建个性化的内容,在 AI 生成的场景中成为主角,无论是未来城市景观还是奇幻世界。
技术规格
当前 Sora 2 的规格包括最长 10 秒的视频长度,分辨率为 720p。该模型通过 ChatGPT Pro 账户进行处理,并为 Pro 订阅者提供优先队列访问。免费用户每月获得 5-10 次视频生成信用,带有水印,而 ChatGPT Plus(每月 20 美元)提供有限的 Sora 2 访问。完全无限制的访问需要每月 200 美元的 ChatGPT Pro。
地理限制使得服务仅限于美国和加拿大。这些地区以外的用户需要采用替代访问方法,我们将在访问、定价及替代方案部分介绍,包括为中国用户提供的解决方案。
示例:音频与物理集成
Prompt: "A figure skater performs a triple axel with a cat sitting calmly on her head.
Medium shot, 35mm lens, ice arena background. The cat's fur ruffles slightly with motion,
maintaining perfect balance. Ice skating sounds—blade scrapes, whooshing rotations—mix
with soft feline purr. Camera follows the rotation smoothly, capturing both the athletic
precision and the absurd juxtaposition."
Result: 8-second clip demonstrating rotational physics accuracy, realistic ice acoustics,
and humorous character interaction.
Why it works: Combines specific physics demands (triple axel mechanics, cat balance) with
detailed audio cues (blade sounds, purr) and clear camera direction.
示例:客串应用
Prompt: "Using my cameo video, place me in a cyberpunk alley at night. Neon signs reflect
in puddles around my feet. I'm adjusting a holographic interface, looking concerned. Medium
close-up, handheld camera, shallow depth of field. Ambient city sounds—distant traffic,
electronic hum, rain on metal."
Result: Personalized sci-fi scene with accurate facial features and body language.
Why it works: Leverages cameos for personalization while specifying environment, action,
camera work, and atmospheric audio.
示例:现实失败建模
Prompt: "Basketball player attempts a three-point shot and misses. Ball rebounds off the
back of the rim, bounces twice on the court with decreasing height, rolls toward the
sideline. Wide shot, stadium lighting, crowd reaction sounds fade as ball rolls to stop.
Realistic friction, spin, and bounce physics."
Result: 7-second clip with accurate trajectory, energy dissipation, and acoustic changes.
Why it works: Specifies failure scenario with detailed physics parameters (rebound, bounce
decay, friction, roll) and matching audio evolution.
提示结构:如何构建有效的 Sora 2 提示
对表现最佳的 Sora 2 提示的研究发现,它们有一个一致的结构:50-100 字的复合句描述,类似于电影导演的镜头脚本。这种系统性的方法与简短、模糊的请求相比,显著提高了输出质量。
提示长度和格式
Sora 2 成功生成分析显示,最佳提示词长度在 50-100 字之间,组织成 2-4 句话。这个长度可以为模型提供足够的细节来理解你的创意愿景,同时保持足够的专注,在 10 秒的限制内连贯执行。单句提示词(“一只猫弹钢琴”)缺乏专业结果所需的特定性,而超过 150 字的提示词往往引入相互冲突的指令。
格式与专业电影制作语言相似。与其描述你想看到的内容,不如像向摄影师简要说明一样构建提示词:确立主题和环境,指定摄像机操作和构图,定义运动和节奏,添加音频提示,然后声明限制。这种导演风格的方法利用了 Sora 2 的增强可控性。
必备组件
每个有效的 Sora 2 提示都包含六个核心组件,每个组件在引导生成过程中都发挥着独特的作用:
组件 | 目的 | 示例 | 视频影响 |
---|---|---|---|
主题 | 行动的主要焦点 | “一名快递员调整头盔” | 定义主要角色/物体和主要行动 |
场景 | 环境背景 | “东京夜晚的雨天霓虹小巷” | 建立情绪、时间、地点和氛围 |
摄像机 | 电影摄影细节 | “中近景,35毫米镜头,浅景深” | 控制视角、构图和视觉风格 |
动作 | 运动动态 | “手持摄像机缓缓推进” | 增加能量、节奏和观众参与度 |
音频 | 声音设计元素 | “湿沥青声,环境雨点声” | 增强沉浸感和情感共鸣 |
限制 | 要避免/保持的内容 | “无镜头光晕,整体光线一致” | 确保质量并防止常见缺陷 |
该组件结构源于研究顶级 Sora 2 内容创作者如何构建他们的提示。每个元素都回答了 AI 需要回答的特定问题,以便生成连贯的视频。
导演语言:电影术语
Sora 2 对专业电影摄影词汇反应极佳。使用精确的电影术语触发了模型对高质量视频内容的训练,从而产生更精致的结果。
摄像机角度和运动对生成内容的感觉有重大影响。像“低角度拍摄”、“荷兰式倾斜”、“推拉镜头”、“跟拍”或“吊臂镜头”这样的术语会产生特定的视觉效果。比较“展示一座建筑”与“从街面水平向上吊臂,揭示一座摩天大楼,晨光照射在玻璃立面” —— 后者生成的构图效果更佳。
镜头规格控制景深和视角。提到“35mm 镜头,浅景深”会创造出电影般的虚化效果,而“24mm 广角”则能捕捉更多环境。 “长焦压缩”则用于产生特定的视觉效果,使视角扁平化。
照明描述通过“金色小时背光”、“强烈的顶灯荧光”、“边缘照明”、“体积雾气”或“实用灯光”等术语建立氛围。这些具体描述引导 AI 生成看起来更专业的照明效果,而不是平淡无奇的照明。
节奏和时机词,如“慢动作”、“时间流逝”、“稳定摄像机”或“快速摇摄”,控制动作展开的方式。音频时机标记,如“0:08 秒时渐强”或“对话从 0:03 秒开始”,将声音与视觉节奏同步。
示例提示分解
让我们分析一个表现优异的 Sora 2 提示,看看组件是如何协同工作的:
Prompt: "A rainy neon alley in Tokyo at night; close-up on a courier adjusting
their helmet; 35mm lens, shallow depth of field; handheld camera pushing in slowly; wet

narrative purpose (introduce character, emotional beat, world reveal). Audio supports pacing
across the sequence.
这些示例展示了如何将结构化的 Sora 2 提示将模糊的想法转化为具体、可执行的指令,从而充分利用模型的全能性。
音频提示工程深度解析
Sora 2 的本地音频生成在 AI 视频领域是一次突破,但控制它需要掌握专门的词汇。虽然视觉提示遵循了既定的电影摄影语言,但音频提示则需要大多数创作者未曾接触过的声音设计术语。本节提供了当前 Sora 2 文档中缺失的系统化音频框架。
音效库
Sora 2 在接收到特定的声学描述符提示时,会生成逼真的声音效果。像“大声噪音”这样的通用术语会产生不可预测的结果,而精确的声音设计词汇则会产生针对性的效果。
<强 id=0>冲击声包括:砰(沉重、闷响的撞击)、裂(尖锐的断裂)、铛(金属碰撞)、溅(水波扩散)、嘎吱(压缩/断裂)、砰(有回音的软撞击)。例如:“篮球与篮板碰撞发出尖锐的裂声,在硬木地板上弹跳两次,发出下降的砰砰声。”
<强 id=0>运动声包括:呼啸(快速空气流动)、沙沙(布料/树叶)、刮擦(表面摩擦)、滑动(滑动摩擦)、颤动(快速振动)、呼呼(空气动力学运动)。例如:“体操运动员在空中旋转,发出清脆的呼啸声,落地垫被柔软的嗡嗡声压缩。”
连续纹理提供环境基础:嗡嗡声(持续的嗡嗡声)、嗡嗡声(高频振动)、隆隆声(低频滚动)、噼啪声(不规则的爆裂声)、静电(白噪声特征)、嗡嗡声(单调的持续声)。例如:“废弃工厂氛围:来自上方灯泡的嗡嗡声,远处机械的隆隆声,间歇性的蒸汽嘶嘶声。”
叠加多个效果可以创建逼真的声音场景。一个街景可能结合“远处的交通隆隆声,偶尔有汽车呼啸声从左到右经过,脚步在混凝土上摩擦,钥匙与金属碰撞的叮当声。”指定空间关系(“远处”、“近距离”、“屏幕右侧”)增强了三维音频。
环境音和背景音频
背景环境音建立环境而不与主要动作竞争。Sora 2 对描述性环境音提示做出反应,这些提示定义了声学特征和密度。
< strong id=0 > 房间音效 构成室内场景的声学基础:“小房间音效,细微的空调嗡嗡声”、“大教堂混响,3 秒衰减”、“紧密的声学,沉寂的声音,录音室特征"或"开放式办公室氛围,键盘点击声和远处的电话铃声”。
< strong id=0 > 自然环境 需要分层描述:“森林氛围——远处的鸟鸣(红雀、麻雀)、树叶间轻风,偶尔的树枝嘎吱声"或"海岸线波浪每 4-5 秒撞击岩石,海鸥叫声中距离,柔和的风声质感”。
< strong id=0 > 人群和人类活动 为场景增添生机:“繁忙的咖啡馆聊天声,偶尔的笑声,咖啡机蒸汽嘶嘶声,陶瓷杯叮当声"或"体育场人群低语逐渐变为 0:07 时的欢呼声,个别声音模糊不清”。
< strong id=0 > 城市声音景观 建立现代环境:“城市交叉口——每 10 秒的交通信号声哔哔声,公共汽车空气刹车嘶嘶声,人行横道上的行人脚步声,远处的警笛声逐渐淡入"或"地铁站台回声,轨道隆隆声逐渐增强,0:08 时的火车呼啸和尖叫声”。
类别 | 描述符 | 使用示例 |
---|---|---|
音效 | 呼啸,咔嚓,砰,溅,嘎吱,飘动,咚咚 | “门重重地关上,玻璃发出高频的叮当声” |
环境音层 | 房间音,混响特性,声学空间,环境底音 | “大型仓库声学效果,2秒混响,远处叉车哔哔声” |
自然声音 | 鸟鸣,风质感,水流,自然的沙沙声 | “森林早晨——知更鸟鸣叫,松树间轻风,远处溪流潺潺” |
人类活动 | 交谈低语、脚步声、物体处理、呼吸 | “餐厅氛围——餐具叮当声、柔和的交谈、椅子刮擦声” |
机械 | 嗯,马达嗡嗡声,气动嘶嘶声,电子蜂鸣声,发动机怠速 | “服务器室——冷却风扇嗡嗡作响,硬盘点击声,偶尔有状态蜂鸣声” |
对话和时序语法
Sora 2 在接收到特定时间指令时,会同步对话与唇部动作。关键在于明确的时间标记和语音考虑。
对话结构遵循以下模式:“[数字]条对话,[语言],同步唇部动作”或“[数字]次对话,说话者之间有自然停顿。”例如:“两条英语对话,同步唇部动作。第一句在 0:02 秒:女性提问。第二句在 0:06 秒:男性回应,点头。”
时间标记控制音频节奏:“对话从 0:03 开始”,“回应前有 2 秒的停顿”,“笑声从 0:05 到 0:08 逐渐增强”,“在 0:04 时发出音频提示。”这些标记将言语、音效和音乐与视觉节奏对齐。
同步唇部质量通过语言指定和情感背景得到提升:“特写,日语对话,两个简短句子,语气克制,完美同步唇部动作”或“动画角色,英语感叹词,夸张的嘴部动作,卡通物理效果。”
<强烈 id=0>寂静与呼吸增加现实感:“角色在说话前深吸一口气”,“从 0:04-0:06 的不适沉默,然后轻叹一口气”,“整个场景中因劳累而呼吸沉重。”这些细节增强了角色的存在感。
音视频同步技巧
Sora 2 在音频提示与视觉事件锚定时表现出色,创造出自然的感觉的因果关系。
<强烈 id=0>冲击同步将声音与接触匹配:“锤子敲击钉子于 0:04——尖锐的金属声,随后有短暂的回音”或“角色的脚在 0:06 时落在水坑中——溅起的水滴声逐渐消失。”
动作提示使用音频来强化动作:“在 0:03 时相机快速右转,伴随着激进的呼啸声”或“汽车在 0:02-0:07 加速,引擎轰鸣声的音调和音量逐渐增加。”
音乐强调强调情感节奏:“当角色转向时,管弦乐在 0:05 开始增强,在 0:09 达到高潮”或“在 0:04 与门砰然关上的同时,低音下降。”
有源-无源混合将现实声音与配乐叠加:“在 0:04,现实中的雨声与忧郁的钢琴声混合,两者共享声音空间”或“心跳节奏(60 BPM)在紧张的场景下作为基础,在 0:06 变得可听。”
示例:分层城市声音景观
Prompt: "Early morning Tokyo intersection, low angle shot. Salaryman waits at crosswalk,
adjusting briefcase. Medium shot, 50mm lens. Urban ambience: distant traffic rumble, nearby
intersection signal beeping every 3 seconds, vending machine hum 20 feet left, occasional
bicycle bell passing. At 0:05, crosswalk signal changes—electronic chirp, footsteps begin
on asphalt. Light rain patter on umbrella starting at 0:03, intensity constant. No music,
pure environmental audio."
Result: 8-second slice-of-life scene with realistic multilayered urban acoustics.
Why it works: Specifies multiple audio layers with spatial relationships (distant, nearby,
20 feet left) and exact timing (signal every 3 seconds, chirp at 0:05). Environmental purity
(no music) focuses attention on acoustic realism. Audio painting complements minimal visual
action.
示例:带有情感潜台词的对话
Prompt: "Close-up on two faces in dimly lit car interior, dashboard glow. She speaks first
at 0:02—short sentence in English, hesitant delivery, eyes avoiding camera. 1-second pause.
He responds at 0:04—longer sentence, resigned tone, slight head shake. Perfect lip sync on
both. Rain on windshield throughout, soft patter. Car idle hum steady. Their breathing
audible in pauses. Dialogue ends at 0:08, silence with rain continues."
Result: 9-second intimate dialogue scene with breathing room and environmental presence.
Why it works: Precise timing for each line (0:02, 0:04) with emotional direction (hesitant,
resigned). Silence and breath between lines add weight. Environmental sounds (rain, idle)
continue through pauses, avoiding awkward dead air. Lip sync emphasis ensures quality.
示例:动作序列音频编排
Prompt: "Wide shot, warehouse fight scene. At 0:02: punch connects—heavy thud with air
displacement whoosh. At 0:04: body hits metal shelving—rattling crash, items tumbling with
multiple impacts. At 0:06: opponent slides across concrete floor—harsh scrape fading. At
0:08: breathing heavy, metallic reverb decay. Each impact synced to visual contact, physics-
accurate collision sounds. Warehouse echo on all impacts, 1-second reverb tail."
Result: 10-second fight choreography with perfectly timed impact sounds and spatial acoustics.
Why it works: Frame-by-frame audio choreography (actions at 0:02, 0:04, 0:06, 0:08) ensures
sync. Specific sound descriptors (thud, whoosh, crash, scrape) matched to action types.
Reverb specification adds environmental character. Physics-accurate request improves realism.
示例:音乐视频美学与视听融合
Prompt: "Slow-motion close-up, person turning head, hair whipping through frame. Shallow DoF,
golden hour backlighting creating rim glow. At 0:00: sustained synthesizer note begins (C3,
bright pad sound). At 0:03: bass pulse enters (80 BPM), synced to hair movement apex. At
0:06: vocal sample enters ('oh' vowel, pitched to F4), layering with synth. At 0:09: all
elements crescendo as camera completes 180-degree rotation. Dreamy, reverb-heavy production,
modern R&amp;B aesthetic."
Result: 10-second music video moment with audio-visual symbiosis.
Why it works: Specifies musical elements by pitch and timbre (C3 synth, F4 vocal), sync to
visual beats (bass at movement apex), and production style (reverb-heavy, R&amp;B). Creates
intentional audio-visual fusion where neither dominates. Timing markers ensure all elements
land on cue.
这些音频提示技术将 Sora 2 视频从视觉震撼提升到完全沉浸式的体验。大多数创作者未能充分利用音频引擎——应用这些系统性的描述符可以立即在输出质量上获得竞争优势。
物理描述符参考
Sora 2 的物理引擎可以实现逼真的运动建模,但控制它需要特定的词汇来描述材料、力和相互作用。这个系统性的参考提供了决定您的视频看起来是否逼真或人工的物理参数。
材料属性
不同材料表现出不同的物理特性。指定材料属性可指导 Sora 2 的模拟精度。

向心力 :“紧密的圆形运动,高向心力”,“宽弧,温和的向心力”,“旋转物体保持圆形路径”。
相互作用和动力学
物体的相互作用决定了场景的真实性。特定的相互作用术语可以提高模拟质量。
碰撞类型 :“弹性碰撞,物体弹开”,“非弹性碰撞,物体粘在一起”,“斜碰撞,物体以角度偏转”。定义碰撞结果。
反弹动力学 :“高反弹,弹到原始高度的 80%”,“低反弹,死弹”,“每次反弹后反弹力减小”。描述多次碰撞场景。
溅射和流体动力学 :“高速溅射,水花向外飞溅”,“轻柔溅射,同心波纹”,“带有次级水滴的溅射”,“位移波与质量成正比”。
摩擦相互作用 :“轮胎摩擦产生的烟雾滑行”,“材料剪切造成的刮擦”,“速度减小的滑动”,“滚动摩擦,平滑运动”。
断裂和破碎 :“脆性断裂,尖锐断裂”,“延性变形,断裂前弯曲”,“破碎成多个碎片”,“从应力点开始裂纹扩展”。
类别 | 术语 | 定义 | 示例用法 |
---|---|---|---|
材料 | 摩擦、弹性、浮力、刚性 | 表面和结构特性 | “低摩擦冰,高弹性橡胶球” |
运动 | 惯性、动量、加速度、速度 | 运动特性 | “高动量卡车,快速加速” |
力 | 重力、阻力、向心力、张力 | 环境对物体的影响 | “强重力,物体下落快;高阻力减缓下降” |
相互作用 | 碰撞,反弹,溅射,断裂 | 物体间的接触动力学 | “弹性碰撞,物体以旋转的方式弹开” |
示例:复杂物理交互
Prompt: "Wide shot, empty parking lot in rain. Shopping cart rolling downhill, gaining speed
with increasing velocity. At 0:04, cart hits speed bump—front wheels lift, cart pivots
forward with rotational inertia. At 0:06, cart crashes back down—elastic collision with
asphalt, high rebound on rear wheels. Cart wobbles from side to side due to unstable center
of mass, metal frame flexing slightly. At 0:08, cart tips over completely—items spill out
with realistic tumbling and rolling. Metallic clatter, wheel spin sound, items bouncing on
wet pavement. Rain throughout, puddle splash at impact."
Result: 10-second demonstration of multiple physics systems interacting realistically.
Why it works: Layers multiple physics concepts (velocity, inertia, elastic collision, center
of mass, flex, tumbling). Each interaction specified with physics terminology. Audio matches
physical events. Tests Sora 2's ability to maintain realistic motion through complex sequence.
示例:水物理展示
Prompt: "Medium shot, swimming pool edge. Diver on board, prepares to jump. At 0:02, diver
jumps—body accelerates downward with gravity, enters water at 0:04. High-velocity splash,
water displaced upward and outward in dome pattern. Underwater bubbles from air displacement,
turbulent mixing. Diver's body decelerates rapidly due to water drag, hair floating upward
from buoyancy. At 0:07, diver surfaces—water streams off body, ripples propagate outward.
Splash sound, underwater muffled acoustics, surface break with water rushing sound."
Result: 9-second water physics demonstration with accurate fluid dynamics.
Why it works: Specifies gravity (acceleration), displacement (splash dome), drag (deceleration),
buoyancy (hair float), and propagation (ripples). Audio transitions underwater (muffled) to
surface (rush). Physics vocabulary ensures realistic water simulation rather than generic
"splash."
示例:破坏物理
Prompt: "Close-up, wine glass on table edge. At 0:02, cat paw swipes glass. Glass pivots
on edge, teeters with unstable equilibrium for 1 second. At 0:03, gravity overcomes friction,
glass tips off table. Falls accelerating at 9.8 m/s², rotating as it falls. At 0:05, glass
impacts hardwood floor—brittle fracture, shatters into sharp fragments radiating outward.
Largest pieces skid across floor with friction, smaller shards bounce with elastic collision.
Audio: glass tipping scrape, falling whoosh, impact crash with high-frequency glass tinkle,
fragments settling. High-speed camera aesthetic, 60fps clarity."
Result: 8-second physics demonstration of tipping, falling, and shattering with accurate dynamics.
Why it works: Specifies equilibrium physics (teetering), precise gravity (9.8 m/s²), brittle
fracture behavior, fragment dynamics (skid vs bounce). High-speed aesthetic ensures clarity.
Audio layers (scrape, whoosh, crash, tinkle) match each physics phase. Demonstrates Sora 2's
ability to model complex failure modes.
示例:软体物理
Prompt: "Medium shot, pillow fight in slow motion. At 0:02, pillow impacts face—soft body
deformation, pillow compresses and conforms to facial contours. Feathers inside redistribute
from impact force. At 0:04, pillow rebounds—elastic recovery, pillow returns to original
shape. Face shows slight displacement from impact pressure, skin deformation realistic. At
0:07, pillow separates, feathers drift in air with low terminal velocity from drag. Slow-
motion 120fps aesthetic. Impact whomp sound, fabric rustle, feather flutter."
Result: 9-second soft body physics with deformation and elastic recovery.
Why it works: Specifies soft body deformation (compress, conform), internal dynamics (feather

这些类别示例提供了可适应您特定创意需求的起始模板。在保持展示的结构原则的同时,调整主题、场景和细节。
高级技巧和风格融合
在基本提示之外,还有更复杂的技巧,这些技巧能够实现独特的视觉标志和复杂的构图。这些高级方法将实验性创作者与技术人员区分开来。
风格融合技巧
Sora 2 允许混合多个美学参考,创建单风格提示中不可用的混合风格。关键在于百分比权重和兼容风格选择。
基于百分比的混合指定风格比例:“70%逼真,30%动漫美学——逼真的物理和光影效果,搭配细腻的动漫风格人物比例和表情丰富的眼睛。”这创造了两种风格之间的独特中间地带。或者:“50%吉卜力工作室水彩背景,50%现代数字角色渲染”则产生具有传统感觉的背景和具有现代细节的角色。
兼容风格搭配非常重要。共享视觉 DNA 的风格可以平滑融合:“电影黑帮照明(高对比度,戏剧性阴影)+现代赛博朋克美学(霓虹强调,科技元素)”可以自然地结合在一起。不兼容的组合,如“逼真医学纪录片+抽象表现主义”,除非有意寻求实验性结果,否则会产生不连贯的结果。
时间风格转变在 10 秒内演变美学:“以鲜明的黑白电影黑色美学开始。在 0:05,颜色从边缘开始渗透。到 0:09,全彩鲜艳的色彩建立。”这通过风格本身的进展创造视觉叙事。
多镜头一致性
在镜头间保持角色、环境和道具的连续性需要明确的参考指令。Sora 2 在生成之间缺乏持久记忆,因此一致性需要系统性的提示。
角色参考保留外观:“与前一个镜头中的同一角色:马尾辫,绿色夹克,可见银色项链。保持精确的面部特征和比例。”对独特特征(疤痕、纹身、配饰)的特定性提高了一致性。
环境锚点维持场景设置:“与前一个镜头相同的巷子:红砖墙上有涂鸦,左侧绿色垃圾桶,右侧金属消防梯。保持一致的夜间照明,路灯形成光斑。“列出永久性环境特征有助于保持连贯性。
照明连贯性防止令人不适的过渡:“保持与前一个镜头相同的右侧柔和的窗户光,相同的色温(暖 3000K),相同的白天时间(傍晚时分)。“照明一致性在潜意识中将镜头连接在一起。
道具追踪确保物体一致性:“相同的皮制公文包,棕色带黄铜扣,角落磨损情况如镜头 1 所示。“重要的道具需要详细描述并重复使用。
负面提示和约束
虽然 Sora 2 缺少正式的负面提示语法,但在提示中嵌入排除项可以提升对质量标准的遵守。
**显式排除**可以防止常见问题:“避免荷兰式角度;屏幕上无文字;无镜头光晕;无变形物体;无不真实的物理错误。”说明不生成的内容可以明确界限。“保持角色比例一致——无解剖学扭曲”可以防止常见的 AI 失败。
**质量约束**可以执行标准:“无像素化,无压缩伪影,无时间错误,无音频不同步。”设定质量基准可以提高结果。
**风格界限**可以保持美学连贯性:“在现实场景中避免卡通夸张;在历史作品中使用现代元素;无历史错误。”防止风格污染。
物理现实检查提升可信度:“真实重量——无漂浮物体;一致的引力方向;无瞬间加速;碰撞中动量保持。”物理约束对抗常见的 AI 捷径。
示例:高级风格融合
Prompt: "60% photorealistic rendering, 40% Studio Ghibli aesthetic. Young woman sits in
modern Tokyo café, but rendering style mixes photographic detail with watercolor softness.
Realistic human proportions with slightly enhanced expressiveness in eyes. Background—photo-
quality café interior with Ghibli-style color palette (warm, slightly oversaturated). Steam
from coffee cup rendered with volumetric realism but moves with anime-style gentle swirls.
Medium shot, 50mm lens. Ambient café sounds—espresso machine, quiet conversation. No
cartoonish exaggeration, maintain photographic composition rules."
Result: Unique hybrid aesthetic impossible to achieve through single-style reference.
Why it works: Explicit percentage weighting, identifies what aspects take each style (proportions
vs color palette), sets boundaries (no cartoonish exaggeration). Creates signature look.

中国访问指南
地理限制将 Sora 2 限制在美国和加拿大,给中国和其他地区的用户带来访问挑战。存在三种主要解决方案,每种都有其权衡。
API 路由服务 :对于需要稳定 Sora 2 访问的中国用户和开发者,API 路由平台提供解决方案。像老张 AI 这样的服务提供针对中国的优化路由到 OpenAI 端点,将延迟从 300-500ms(直接 VPN)降低到 80-120ms 通过国内骨干网络。这种方法提供按使用付费的定价,无需每月 200 美元的订阅锁定,适合大量生成工作流程或成本意识强的创作者。API 访问模式特别适合将 Sora 2 集成到应用程序或批量生成视频的创作者。
ChatGPT Pro 订阅 :习惯于订阅服务的用户可以通过提供国际支付平台的网站获取 ChatGPT Pro。例如,fastgptplus.com 提供了支付宝和微信支付的支持,简化了订阅流程,大约 5 分钟内完成设置,每月 158 元(相当于 20 美元的 Plus 版本,Pro 版本价格不同)。此方法提供完整的官方访问权限,包括 iOS 应用和网页界面,但无论使用强度如何,都需要维持每月订阅。
性能考虑 :直接通过 VPN 连接到 sora.com 会引入延迟,影响生成队列位置和完成时间。通过中国优化网络的 API 路由可以大幅减少这种延迟。对于在中国大陆每天生成多个视频的创作者来说,API 路由通常比每月 200 美元的高延迟 Pro 订阅提供更好的性价比。
支付方式 :国际信用卡适用于直接订阅 OpenAI,但许多中国用户无法访问这些支付渠道。支持支付宝、微信支付或银联的支付平台消除了这一障碍。在确定访问方式之前,请检查支付兼容性。
随着 Sora 2 的成熟,API 过渡生态系统持续发展。根据 OpenAI 的公告,官方 API 访问仍处于“即将推出”状态,这可能在发布后显著改变访问格局。
常见问题故障排除
即使精心设计的提示也可能偶尔产生意外结果。系统性的故障排除可以识别和解决 Sora 2 的常见故障模式。
物理和运动错误
不切实际的运动通常源于矛盾的物理指令。问题:“快速汽车追逐与慢动作爆炸”造成时间上的不一致。解决方案:保持一致的时间尺度——要么“实时追逐与实时爆炸”,要么“整个场景以 120fps 慢动作呈现。”
物体变形发生在 Sora 2 在不可兼容的状态之间插值时。问题:“角色在旋转时面部变形不自然。”解决方案:添加约束“在整个旋转过程中保持面部结构一致,无变形或扭曲。”
重力不一致出现在复杂场景中。问题:“一些物体漂浮,而其他物体正常下落。”解决方案:明确重力指定——“重力方向向下一致,所有物体均受 9.8 m/s²加速度影响。”
在/之后修复示例
- 人物跳跃,落在蹦床上,奇怪的弹跳
- 在0:03时,人物跳上蹦床,蹦床表面在重量下变形,弹性回弹在0:05将人物向上弹起,具有现实感的能量守恒,人物在0:07时达到最高点,开始受重力加速度下落
音频问题
< strong id=0 > 同步问题 发生在时间标记与视觉节奏冲突时。问题:“0:03 时有对话,但角色的嘴巴直到 0:05 才动。” 解决方案:明确的同步指令——“对话从 0:03 开始,全程完美唇形同步,角色嘴巴运动与第一句话同时开始。”
缺少声音层是由于模糊的音频提示造成的。问题:“尽管有动作,场景却感觉空旷。”解决方案:叠加多个音频元素——“石子路上的脚步声、远处的交通、树木间的风声、环境鸟鸣”而不是通用的“户外声音”。
音量平衡问题源于不充分的突出度指定。问题:“背景音乐淹没了重要的对话。”解决方案:“背景音乐音量调至-20dB,对话在 0dB 时突出且清晰,说话时音乐降低音量。”
修复前/后示例 :
- 修复前:“打斗场景有拳头声音,听起来很奇怪”
- 在0:02时,拳头击中——沉重的砰声,空气呼啸;在0:04时,身体撞击墙壁——沉闷的撞击声,墙壁裂缝;在0:06时,呼吸沉重,所有撞击都有环境混响;每个声音与视觉接触同步,帧准确。
一致性问题和
**角色外观变化**在生成的镜头之间。问题:“同一角色在每段视频中看起来都不同。”解决方案:创建详细的角色表单提示——“角色:身高5'6英寸的女性,肩部长棕色头发带有金色挑染,绿色眼睛,左脸颊上有小疤痕,穿着带有拉链细节的红皮夹克,黑色牛仔裤,白色运动鞋”——精确重复使用。
**光线变化**破坏了沉浸感。问题:“剪辑之间的光线方向改变。”解决方案:“保持一致的光线:来自右侧的柔和窗户光,3000K 暖色调,同一时间(下午 2 点的太阳角度)” ——在相关的提示中复制光线描述。
环境连续性中断 。问题:“背景细节改变。”解决方案:列出永久性特征——“背景:带有箭头形状绿色涂鸦标签的砖墙,左侧有金属垃圾桶,右侧有铁丝网围栏”——为 Sora 2 提供可参考的环境锚点。
最佳实践与优化
工作流程优化
在投入完整的10秒生产之前,每个项目都应从5-7秒的测试生成开始,探索核心视觉和音频概念。这个快速迭代周期可以早期识别物理问题、风格不匹配或音频问题。根据测试结果调整提示,然后扩展到完整时长。
将提示组织到按用途分类的可重复使用的库中:角色描述、环境设置、摄像机风格、音频调色板。复制粘贴已知有效的组件可以加快创建速度并确保一致性。以数字形式对提示进行版本控制(tokyo-alley-v3,character-jane-v2)以跟踪迭代。
在生成之前建立质量验收标准:物理现实阈值、音频同步容差、美学一致性标准。立即拒绝不符合标准的输出,而不是尝试挽救。投入在优化提示上的时间超过了在勉强可接受的输出上浪费的时间。
成本和信用管理
免费层用户应将每月信用视为学习预算——测试提示结构、实验物理词汇、探索风格参考。避免在生产工作中消耗信用;仅使用此层进行技能发展。
ChatGPT Plus 用户偶尔可以访问,但面临排队限制。将 Plus Sora 访问保留给对时间不敏感的项目或次要资产生成。监控使用模式——如果每月生成 20 个以上视频,Pro 订阅或 API 访问变得具有成本效益。
有关不同层级和用法模式的详细成本分析,请参阅我们的全面的 ChatGPT 定价指南 ,比较 Plus、Pro 和 API 经济性。《Plus 与 Pro 比较 》分析了哪个订阅层级适合不同的创作者工作流程。
API 访问(当可用时)采用按使用付费的经济模式——非常适合可变工作量、批量处理或自动化管道。计算盈亏平衡点:每月 200 美元的 Pro 订阅等于通过 API 生成大约 800-1,000 个视频的成本,每 10 秒生成成本估计为 0.20-0.25 美元。
持续学习
研究 OpenAI 社区论坛、Twitter 和专门 Discord 服务器上创作者分享的 Sora 2 输出。逆向工程成功的视频——哪种提示结构产生了那种物理精度?他们是如何实现那种音频混音的?向他人学习可以加速技能发展,而不仅仅是依靠试错。
每周尝试一种新技术:本周掌握对话时序语法,下周探索风格融合,接下来一周练习多镜头一致性。系统性地构建技能优于零散的实验。
将成功与失败并存。失败的提示词教导边界条件——Sora 2 还无法实现的内容,哪些物理场景会崩溃,音频同步失败的地方。这种知识可以防止重复失败的方法,并使期望更加现实。
AI 视频生成领域正在迅速发展。Sora 2 代表了当前最先进的技术,但竞争对手在进步,OpenAI 也在更新模型。了解能力变化、价格调整和功能添加,以持续优化您的流程。
精通 Sora 2 提示词将这个工具从新奇转变为专业创意工具。应用这些系统性的技术——结构化提示词、音频工程、物理词汇、故障排除方法——生成与人类执导的视频难以区分的视频。最佳的 Sora 2 提示词不是展示 AI 能力;而是完美执行你的创意愿景。
