Social Short Production

社交短视频制作

Produce an intentional short video, not merely a vertical crop. Treat each platform as a distinct playback, interface, policy, and measurement environment.
制作一支有明确意图的短视频，而不只是把横版视频裁成竖版。应将每个平台视为不同的播放、界面、政策和衡量环境。

Evidence labels

证据标签

Interpret guidance by its label:
  • Documented fact — stated by a platform, regulator, standard, or other primary authority. Recheck volatile facts before delivery.
  • Research finding — supported in a cited study but bounded by that study's population and context.
  • Production heuristic — a starting practice to test against the brief, audience, platform preview, and analytics; never present it as an algorithmic rule.
Do not turn a heuristic such as “hook in three seconds,” “cut every two seconds,” or “master at -14 LUFS” into a universal requirement. Platform metrics and recommendation systems change, and audience intent can outweigh tempo.
根据标签解读指导原则：
  • 已记录事实（Documented fact）——由平台、监管机构、标准或其他主要权威来源明确说明。交付前应重新核查可能发生变化的信息。
  • 研究发现（Research finding）——有引用研究支持，但结论受该研究样本和背景的限定。
  • 制作经验法则（Production heuristic）——可作为起点，并根据 brief、受众、平台预览和 analytics 进行测试；不可将其表述为算法规则。
不要把“三秒内设置 hook”“每两秒切一次”或“母版控制在 -14 LUFS”等经验法则变成通用要求。平台指标和推荐系统会发生变化，观众意图也可能比剪辑节奏更重要。

Define the production contract

定义制作合同

Before scripting or cutting, resolve the fields that can change the result:
  1. Objective: awareness, qualified attention, education, community response, lead/action, or conversion. Select one primary outcome and at most two guardrails.
  2. Audience state: who is watching, what they already know, what they doubt, and why this clip is relevant in this viewing context.
  3. Promise: the specific value delivered by watching. Make it provable inside the clip.
  4. Source of truth: approved brief, transcript, footage, product build, data, citations, or spokesperson. Mark unverified claims.
  5. Distribution surfaces: exact organic, paid, boosted, or partner placements. “Social” is not a platform specification.
  6. Action after viewing: remember, comment, save, share, follow, click, install, purchase, or watch a longer item.
  7. Constraints: duration ceiling, languages, brand rules, accessibility, age or regulated category, review deadline, budget, and available analytics.
  8. Rights and representation: owners and license scope for footage, music, graphics, fonts, trademarks, likenesses, voices, testimonials, and synthetic media.
If a critical item is unknown, state an assumption and make the plan reversible. Do not invent product claims, testimonials, measurements, or permissions.
在编写脚本或剪辑之前，应明确所有可能影响最终结果的字段：
  1. **目标：**认知、有效关注、教育、社区互动、潜在客户/行动或转化。选择一个主要目标，最多设置两个护栏指标。
  2. **受众状态：**谁在观看、他们已经知道什么、存在哪些疑问，以及这支短片为何与当前观看场景相关。
  3. **承诺：**观众观看后将获得的具体价值。必须能在短片内容中得到证明。
  4. **事实来源：**已批准的 brief、转录稿、素材、产品构建、数据、引用来源或发言人。标记所有未经验证的主张。
  5. 分发渠道：****具体的自然投放、付费投放、boost 或合作发布位置。“社交媒体”并不是平台规格。
  6. **观看后的行动：**记住、评论、收藏、分享、关注、点击、安装、购买，或观看更长的内容。
  7. **约束条件：**时长上限、语言、品牌规则、无障碍要求、年龄限制或受监管品类、审核截止时间、预算和可用的 analytics。
  8. **权利与呈现：**素材、音乐、图形、字体、商标、肖像、声音、用户评价和合成媒体的所有者及许可范围。
如果某个关键项未知，应明确说明假设，并确保计划可逆。不得虚构产品主张、用户评价、测量结果或授权情况。

Build a dated platform contract

建立带日期的平台合同

Recheck official documentation on the day of export. Record the verification date and placement; organic, ad, boosted, and in-app-created posts can have different rules.
导出当天应重新核查官方文档。记录核查日期和发布位置；自然发布、广告、boost 和应用内创建的帖子可能适用不同规则。

Current reference points — verified 2026-07-09

SurfaceDocumented facts useful to productionProduction consequence
YouTube ShortsSquare or vertical uploads up to three minutes are categorized as Shorts under YouTube's current upload rules. Since 2025-03-31, a public Shorts “view” counts starts or replays with no minimum watch time; “engaged views” remains available for viewers who chose to continue watching. Shorts over one minute with an active Content ID claim are blocked globally. [S1][S2]Do not compare public views with old Shorts cohorts without noting the definition change. Check claimed music before using a 1–3 minute cut. Export without pillarbox or letterbox bars.
Instagram ReelsInstagram accepts Reels from 1.91:1 through 9:16, with at least 30 fps and 720-pixel resolution. Boosted Reels have a narrower contract: currently less than 90 seconds and full-screen 9:16. [S3][S4]Prefer a 9:16 organic master when the intent is immersive vertical viewing, but create a placement-specific boost version rather than assuming the organic upload is eligible.
TikTok in-feed adsFor non-Spark in-feed ads, TikTok currently recommends 9:16 at at least 540×960, accepts common video containers, and publishes placement-specific rules. TikTok says its safe zone changes with dimensions, ad-caption length, and add-ons and supplies downloadable overlays. Organic and Spark contracts differ. [S5]Never hard-code one TikTok safe rectangle for all deliveries. Use the current overlay for the exact placement and caption/add-on configuration. Recheck organic upload behavior in the target account/app.
LinkedIn video / immersive feedUploaded video can be eligible for LinkedIn's immersive vertical experience, but creators cannot post directly into that feed. LinkedIn warns that its UI can overlap edges. Current upload limits include 3 seconds minimum, up to 15 minutes on desktop or 10 on mobile, and aspect ratios from 1:2.4 to 2.4:1. [S6][S7]Frame a professional-feed version with edge clearance, useful context, and a non-feed-dependent CTA. Do not promise immersive-feed placement.
Documented fact: TikTok, Meta, YouTube, and LinkedIn can change specs, labels, metrics, or eligibility independently. A local render passing yesterday's table is not final delivery approval.
Production heuristic: Use a clean 1080×1920, 9:16 working master when all target surfaces support it, then derive and preview separate platform renditions. This is a workflow convenience, not proof that one edit is optimal everywhere.
For every target, capture:
text
platform + placement | organic/paid/boosted | max eligible duration
aspect/resolution/fps | accepted codec/container | max file size
UI overlay/safe-zone source + date | caption mode | cover crop
music license path | sponsorship/AI disclosure controls
upload metadata | analytics definitions | test-upload result
发布渠道对制作有帮助的已记录事实对制作的影响
YouTube Shorts根据 YouTube 当前的上传规则，正方形或竖版且最长三分钟的视频会被归类为 Shorts。自 2025-03-31 起，公开 Shorts 的“观看次数”计入开始播放或重播，不设最低观看时长；“engaged views”仍会提供给选择继续观看的观众。超过一分钟且存在有效 Content ID claim 的 Shorts 会在全球范围内被屏蔽。[S1][S2]将公开观看次数与旧版 Shorts cohort 比较时，必须说明统计定义发生了变化。使用 1–3 分钟 cut 前应检查音乐版权 claim。导出时不要添加 pillarbox 或 letterbox 黑边。
Instagram ReelsInstagram 接受宽高比为 1.91:1 至 9:16、至少 30 fps 且分辨率不低于 720 像素的 Reels。Boosted Reels 的合同要求更严格：目前必须短于 90 秒，并采用全屏 9:16。[S3][S4]当目标是沉浸式竖屏观看时，优先制作 9:16 的自然投放母版，但应创建特定发布位置的 boost 版本，不能假设自然上传版本一定符合要求。
TikTok 信息流广告对于非 Spark 信息流广告，TikTok 目前建议使用 9:16、至少 540×960 的分辨率，支持常见视频容器，并发布按发布位置区分的规则。TikTok 表示，安全区域会随尺寸、广告文案长度和附加元素变化，并提供可下载的 overlay。自然发布和 Spark 的合同不同。[S5]不要为所有交付版本硬编码一个 TikTok 安全矩形。应针对准确的发布位置和文案/附加元素配置使用当前 overlay。还应在目标账户或应用中重新核查自然上传行为。
LinkedIn 视频/沉浸式信息流上传的视频可能符合 LinkedIn 沉浸式竖屏体验的要求，但创作者无法直接向该信息流发布内容。LinkedIn 警告其 UI 可能遮挡边缘。当前上传限制包括最短 3 秒，桌面端最长 15 分钟、移动端最长 10 分钟，宽高比范围为 1:2.4 至 2.4:1。[S6][S7]为专业信息流版本预留边缘空间、提供必要背景，并使用不依赖该信息流的 CTA。不要承诺一定获得沉浸式信息流发布位置。
**已记录事实：**TikTok、Meta、YouTube 和 LinkedIn 均可独立更改规格、标签、指标或资格条件。本地 render 昨天通过表格检查，并不等于获得了最终交付批准。
**制作经验法则：**如果所有目标渠道都支持，可使用干净的 1080×1920、9:16 工作母版，然后派生并预览独立的平台版本。这是一种工作流便利措施，并不能证明同一条剪辑在所有平台上都最优。
对每个目标渠道，记录：
text
平台 + 发布位置 | 自然/付费/boost | 最长合格时长
宽高比/分辨率/fps | 支持的 codec/容器 | 最大文件大小
UI overlay/安全区域来源 + 日期 | 字幕模式 | 封面裁切
音乐许可路径 | 赞助/AI 披露控制项
上传元数据 | analytics 定义 | 测试上传结果

Make the opening earn attention honestly

用诚实的方式让开场赢得注意力

A hook is the first coherent reason to continue, not necessarily the first spoken sentence. It can be visual, verbal, sonic, or a combination.
  1. Name the audience tension or show the result.
  2. State or imply a specific promise.
  3. Supply enough context to interpret the promise.
  4. Begin proof quickly.
  5. Pay off the promise before asking for action.
Useful opening modes include result-first demonstration, a precise contradiction, a consequential before/after, an unresolved but answerable question, or an expert claim immediately paired with evidence.
Production heuristic: Remove greetings, logos, and throat-clearing unless recognition or trust is itself the value. Keep an intro only when it improves comprehension, authority, or narrative tension.
Reject an opening when it:
  • withholds essential context merely to manufacture confusion;
  • promises an outcome the clip does not deliver;
  • uses an alarming visual unrelated to the subject;
  • presents a correlation as causation or a simulation as evidence;
  • makes a health, finance, safety, or performance claim without adequate support;
  • depends on tiny text or audio alone to be intelligible.
Hook 是继续观看的第一个连贯理由，不一定是第一句口播。它可以是视觉、语言、声音或多种元素的组合。
  1. 点出受众痛点或展示结果。
  2. 明确或暗示具体承诺。
  3. 提供足够背景，使观众能够理解承诺。
  4. 尽快开始提供证据。
  5. 在要求观众采取行动前兑现承诺。
实用的开场方式包括结果优先演示、精确的反常识观点、有重要影响的前后对比、可解答但暂未解决的疑问，或将专家主张立即与证据配对。
**制作经验法则：**除非品牌认知或信任本身就是价值，否则应删除问候、Logo 和无实质信息的开场铺垫。只有当开场有助于理解、确立权威或营造叙事张力时才应保留。
拒绝以下开场：
  • 仅通过隐瞒必要背景来制造困惑；
  • 承诺短片无法交付的结果；
  • 使用与主题无关的 alarming 视觉元素；
  • 将相关性表述为因果关系，或将模拟内容当作证据；
  • 在缺乏充分支持时作出健康、财务、安全或效果主张；
  • 仅依靠微小文字或音频才能理解。

Choose a structure that matches the job

选择与任务匹配的结构

Select a reasoning shape instead of forcing every clip into the same formula:
  • Demonstration: result → setup → critical steps → verified result → next action.
  • Explanation: surprising claim → necessary context → mechanism → example/evidence → implication.
  • Problem/repair: recognizable failure → cause → correction → proof → prevention.
  • Story: consequential moment → minimal orientation → escalation/turn → resolution → meaning.
  • Expert excerpt: strong self-contained claim → context needed for fairness → supporting detail → conclusion/attribution.
  • Announcement: what changed → why it matters → evidence/demo → who it affects → date/action.
Research finding: Guo, Kim, and Rubin found shorter educational videos associated with more engagement in a large MOOC dataset, but that population, task, and video length range do not establish an optimal duration or cut cadence for social feeds. Use the finding as support for removing avoidable material, not as a universal duration threshold. [R1]
End when the promise is complete. A 19-second complete explanation is better than padding to 30 seconds; a careful 70-second demonstration is better than compressing away the evidence to fit folklore.
选择一种推理结构，不要强行将每支短片套入相同公式：
  • **演示：**结果 → 设置 → 关键步骤 → 已验证结果 → 下一步行动。
  • **解释：**反常识主张 → 必要背景 → 机制 → 示例/证据 → 影响。
  • **问题/修复：**可识别的问题 → 原因 → 修正方法 → 证明 → 预防措施。
  • **故事：**重要时刻 → 最少背景 → 升级/转折 → 解决 → 意义。
  • **专家摘录：**有力且可独立理解的主张 → 保证公平性所需背景 → 支撑细节 → 结论/归属。
  • **公告：**发生了什么变化 → 为何重要 → 证据/演示 → 影响哪些人 → 日期/行动。
**研究发现：**Guo、Kim 和 Rubin 在一个大型 MOOC 数据集中发现，较短的教育视频与更多互动相关，但该研究的人群、任务和视频时长范围并不能确定社交信息流中的最佳时长或剪辑节奏。该发现可用于支持删除冗余内容，而不能作为通用时长阈值。[R1]
承诺完成时即应结束。19 秒的完整解释优于填充至 30 秒；70 秒的严谨演示也优于为了迎合未经证实的说法而压缩掉证据。

Convert the structure into a beat-and-shot ledger

将结构转化为节拍与镜头清单

Plan in beats. A beat is a change in question, claim, proof, emotion, location, or action—not an arbitrary number of seconds.
Use this schema:
Time rangeNarrative jobViewer questionSpoken contentVisual evidence/actionOn-screen text/captionAudio eventSource/rightsSafe-zone riskExit condition
Require every beat to do at least one job: advance, prove, orient, contrast, or resolve. Remove beats that only decorate a finished thought.
For source-led edits:
  • transcribe before selecting when practical;
  • preserve enough lead-in and follow-through to avoid changing meaning;
  • distinguish jump-cut repair from deceptive reordering;
  • never splice separate phrases into a claim the speaker did not make;
  • retain source timecodes and filenames in the ledger;
  • identify b-roll as evidence, illustration, reconstruction, or atmosphere;
  • request approval for sensitive context changes.
For capture or animation planning:
  • vary shot scale or composition when it clarifies new information;
  • reserve close detail for proof, not random energy;
  • give demonstrations readable screen time;
  • motivate transitions with action, shape, sound, subject, or idea;
  • leave short handles around source takes for editorial repair;
  • plan the first and last frames deliberately because feeds may loop.
Production heuristic: Introduce a visual reset when attention or comprehension needs one, not on a timer. A cut that adds no information can create fatigue; a held shot with evolving evidence can retain attention.
按节拍进行规划。节拍是问题、主张、证据、情绪、地点或行动的变化，而不是任意设定的秒数。
使用以下结构：
时间范围叙事任务观众问题口播内容视觉证据/动作屏幕文字/字幕音频事件来源/权利安全区域风险退出条件
每个节拍至少必须完成一项任务：推进、举证、定位、对比或解决。删除只能装饰已完成观点的节拍。
对于以源素材为基础的剪辑：
  • 在实际可行时，先转录再选择片段；
  • 保留足够的前因和后续内容，避免改变原意；
  • 区分 jump-cut 修复与误导性重排；
  • 绝不要将来自不同语句的片段拼接成发言人未曾表达的主张；
  • 在清单中保留源时间码和文件名；
  • 将 b-roll 标记为证据、示意、重构或氛围素材；
  • 对敏感背景的更改取得批准。
对于拍摄或动画规划：
  • 当景别或构图变化有助于呈现新信息时，应有所变化；
  • 将近距离细节用于举证，而不是随意制造节奏；
  • 为演示提供足够可阅读的屏幕展示时间；
  • 使用动作、形状、声音、主体或概念为转场赋予动机；
  • 在源素材片段两端预留短余量，以便后期修复；
  • 有意识地设计首帧和尾帧，因为信息流可能会循环播放。
**制作经验法则：**在观众注意力或理解需要重置时引入视觉变化，而不是按固定计时器切换。没有增加信息的剪切可能造成疲劳；持续呈现新证据的固定镜头反而可以维持注意力。

Protect content from interface occlusion

防止内容被界面遮挡

Safe zones are delivery data, not taste.
Documented fact: TikTok's published safe zone varies with caption length and add-ons, Meta provides Reels safe-zone checking resources, and LinkedIn instructs creators to keep key elements away from all edges. [S5][S6][S8]
For each rendition:
  1. Obtain the current official template, preview, or placement checker.
  2. Overlay it in the edit/compositor at the actual output resolution.
  3. Keep faces, product proof, disclosures, captions, logos, data labels, and CTA meaning inside the unobstructed region.
  4. Check the right-side action rail, bottom caption/CTA area, top account/title region, gesture/home indicators, and cover/profile crops.
  5. Preview with both a short and maximum expected post caption when the UI changes with caption length.
  6. Test at small-phone scale and at least one tall and one less-tall viewport.
  7. Save a UI-preview screenshot with the delivery record.
Do not solve occlusion by shrinking everything. Recompose the shot, move noncritical decoration outward, shorten copy, or create a platform variant.
安全区域是交付数据，而不是审美偏好。
**已记录事实：**TikTok 公布的安全区域会随字幕长度和附加元素变化，Meta 提供 Reels 安全区域检查资源，LinkedIn 建议创作者将关键元素远离所有边缘。[S5][S6][S8]
对每个版本：
  1. 获取当前官方模板、预览工具或发布位置检查器。
  2. 在实际输出分辨率下将其叠加到编辑或合成画面中。
  3. 确保人物面部、产品证据、披露信息、字幕、Logo、数据标签和 CTA 的含义都处于无遮挡区域内。
  4. 检查右侧操作栏、底部字幕/CTA 区域、顶部账户/标题区域、手势/Home 指示符，以及封面/头像网格裁切。
  5. 使用短文案和预期最长帖子文案分别预览，因为 UI 可能随字幕长度变化。
  6. 在小尺寸手机屏幕上测试，并至少测试一种高屏和一种较低屏幕的视口。
  7. 将 UI 预览截图保存到交付记录中。
不要通过缩小所有内容来解决遮挡问题。应重新构图、将非关键装饰元素移向外侧、缩短文案或创建平台专属版本。

Caption for access and comprehension

为无障碍和理解制作字幕

Documented fact: WCAG 1.2.2 requires captions for prerecorded audio content in synchronized web media at Level A; captions include meaningful non-speech audio and speaker identification, not dialogue alone. [S9]
Decide between:
  • Closed/platform captions: toggleable and accessible to the platform/player; upload and correct a sidecar or review native transcription.
  • Open/burned captions: guaranteed visual styling and visibility but cannot be turned off.
  • Both: only when platform behavior will not show duplicate captions. Keep a clean master and caption file even if distributing an open-caption version.
Caption production rules:
  • transcribe meaning accurately; do not “improve” claims while captioning;
  • synchronize to speech and preserve phrase boundaries;
  • identify a changed or off-screen speaker when needed;
  • include meaningful sounds such as 
    [alarm]
    or 
    [glass breaks]
    ;
  • use high-contrast text with a stable backing treatment over variable imagery;
  • avoid covering a speaker's mouth, hands, product controls, charts, or evidence;
  • use a readable size at actual phone scale;
  • reduce copy or extend exposure when the viewer cannot read it naturally;
  • proof names, numbers, units, URLs, technical terms, and translated lines manually;
  • test without audio and with captions disabled.
Professional subtitle standards emphasize accuracy, synchronization, readable presentation, and tradeoffs between speech density and reading speed; do not treat a single characters-per-second limit as universal across languages or audiences. [P1]
If essential visual information is not conveyed by narration, provide an accessible description in the spoken track, post text, or platform-supported alternative as the delivery context permits.
**已记录事实：**WCAG 1.2.2 要求同步网页媒体中的预录音频内容在 Level A 下提供字幕；字幕应包含有意义的非语音音频和说话者标识，而不只是对白。[S9]
在以下方式之间做出选择：
  • **封闭/平台字幕：**用户可通过平台或播放器切换和访问；上传并校正 sidecar 文件，或审核平台原生转录内容。
  • **开放/烧录字幕：**视觉样式和可见性更稳定，但用户无法关闭。
  • **两者同时使用：**仅当平台行为不会造成重复字幕时使用。即使分发开放字幕版本，也应保留干净母版和字幕文件。
字幕制作规则：
  • 准确转录含义；不要在制作字幕时“改进”主张；
  • 与语音同步，并保留短语边界；
  • 必要时标明说话者发生变更或位于画面之外；
  • 包含 
    [alarm]
    或 
    [glass breaks]
    等有意义的声音；
  • 使用高对比度文本和稳定的衬底，以适应多变的画面背景；
  • 避免遮挡说话者的嘴部、手部、产品控件、图表或证据；
  • 在实际手机尺寸下保持可读的字号；
  • 当观众无法自然读完文字时，应减少文字或延长展示时间；
  • 人工核对专有名词、数字、单位、URL、技术术语和翻译后的台词；
  • 分别在关闭音频和关闭字幕的情况下进行测试。
专业字幕标准强调准确性、同步性、可读的呈现，以及语音密度与阅读速度之间的权衡；不要将单一的 characters-per-second 限制视为适用于所有语言和受众的通用标准。[P1]
如果必要视觉信息无法通过旁白传达，应在交付条件允许的情况下，通过口播、帖子文字或平台支持的替代方式提供无障碍描述。

Mix speech, music, and effects around meaning

围绕含义混合语音、音乐和音效

Build the mix in this order:
  1. Repair dialogue only as needed: remove distracting noise, clicks, and excessive room tone without creating artifacts.
  2. Match dialogue tone and level across cuts; automate individual words before applying blunt compression.
  3. Add music for pace, emotion, or continuity, not as mandatory wallpaper.
  4. Duck or arrange music around consonants and key claims; check small-phone speakers and mono compatibility.
  5. Use SFX to explain an action, establish space, punctuate a verified change, or support a transition. Remove effects that compete with language.
  6. Meter the full program and inspect true peaks; then audition the encoded upload.
Documented fact: ITU-R BS.1770-5 defines algorithms for measuring programme loudness and true-peak level; it does not prescribe a universal social-platform delivery loudness. [S10]
Production heuristic: For a conventional stereo social master, begin tests around -16 to -14 LUFS integrated with true peak no higher than -1 dBTP, then adjust to the content and the platform's current behavior. This range is not a platform guarantee. Preserve a higher-quality mix master, compare speech intelligibility after platform transcode, and avoid winning loudness at the cost of distortion or fatigue.
Run four listening passes: normal device, quiet volume, phone speaker, and headphones. Run a mute pass. A music-only hook fails users watching silently; text-only proof fails users who are not watching continuously.
按以下顺序构建混音：
  1. 仅在必要时修复对白：去除干扰噪声、爆音和过量室内底噪，但不要产生伪影。
  2. 统一各剪切片段的对白音色和电平；先自动化处理单词电平，再使用大范围压缩。
  3. 使用音乐建立节奏、情绪或连续性，而不是将音乐作为必需的背景填充。
  4. 在辅音和关键主张附近 duck 音乐或重新安排音乐；检查小尺寸手机扬声器和 mono 兼容性。
  5. 使用 SFX 解释动作、建立空间、强调已验证的变化或支持转场。移除会与语言竞争的音效。
  6. 对完整节目进行响度计量并检查 true peak；然后试听编码后的上传文件。
**已记录事实：**ITU-R BS.1770-5 定义了测量节目响度和 true-peak 电平的算法，但它并未规定适用于所有社交平台的统一交付响度。[S10]
**制作经验法则：**对于传统立体声社交母版，可以先在 integrated loudness 约 -16 至 -14 LUFS、true peak 不高于 -1 dBTP 的范围内进行测试，再根据内容和平台当前行为进行调整。该范围并非平台保证。应保留更高质量的混音母版，比较平台转码后的语音清晰度，并避免以失真或疲劳为代价追求响度。
执行四轮试听：常规设备、低音量、手机扬声器和耳机。同时执行静音检查。仅为音乐设计的 hook 无法服务于静音观看用户；只有文字的证据也无法服务于没有持续观看的用户。

Keep authenticity, disclosure, consent, and rights visible

保持真实性、披露、同意和权利可见

Run these checks before lock:
  • Sponsorship/material connection: place a clear disclosure with the endorsement, in the same language, where viewers will notice it. The FTC says a platform disclosure tool may not by itself be adequate and defines clear-and-conspicuous disclosure contextually. [S11]
  • Synthetic or altered media: use the current platform control and visible context when required. YouTube requires disclosure for realistic, meaningful altered/synthetic content; TikTok requires labels on realistic AI-generated images, audio, or video and prohibits some harmful or nonconsensual likeness uses even if labeled; Meta may apply “AI info” based on detected signals or self-disclosure. [S12][S13][S14]
  • Provenance: preserve source IDs, edit decisions, releases, licenses, model/tool involvement, and export hashes. C2PA Content Credentials can carry cryptographically bound provenance, but provenance is context—not proof that a claim is true. [S15]
  • Music: verify commercial scope, platform, territory, duration, paid/organic use, attribution, and expiration. TikTok recommends its Commercial Music Library for content promoting a brand; Meta says its general licensed library is intended for personal, non-commercial use and points commercial users toward Sound Collection; YouTube limits its copyright-safety assurance to its own Audio Library and warns that longer Shorts with active claims can be blocked. [S16][S17][S1]
  • People: obtain appropriate permission for likeness, voice, testimonial, private location, and sensitive personal data. Do not infer consent from public availability.
  • Claims: keep evidence snapshots for prices, results, rankings, quotes, and before/after comparisons. Show simulations and reconstructions as such.
Do not strip authenticity metadata unnecessarily. If a platform transcode removes it, retain the signed/source asset and manifest in the production archive and still use human-visible disclosure where required.
锁定版本前执行以下检查：
  • **赞助/重大关系：**在背书内容附近使用观众容易看到的清晰披露，并使用相同语言。FTC 表示，仅依赖平台披露工具本身可能并不充分，并根据具体情境定义“清晰且显著”的披露。[S11]
  • **合成或经过修改的媒体：**按要求使用当前平台控制和可见上下文。YouTube 要求对逼真且有实质意义的修改或合成内容进行披露；TikTok 要求对逼真的 AI 生成图片、音频或视频添加标签，并禁止某些有害或未经本人同意的肖像用途，即使已添加标签；Meta 可能根据检测信号或自我披露应用“AI info”。[S12][S13][S14]
  • **来源记录：**保留 source ID、剪辑决策、授权书、许可证、模型/工具参与情况和导出 hash。C2PA Content Credentials 可以承载通过密码学绑定的来源记录，但来源记录只是上下文，不能证明某项主张为真。[S15]
  • **音乐：**核实商业使用范围、平台、地区、时长、自然/付费投放用途、署名要求和到期时间。TikTok 建议推广品牌的内容使用其 Commercial Music Library；Meta 表示其通用授权音乐库面向个人、非商业用途，并将商业用户引导至 Sound Collection；YouTube 仅对自己的 Audio Library 提供版权安全保证，并警告存在有效 claim 的较长 Shorts 会被屏蔽。[S16][S17][S1]
  • **人物：**就肖像、声音、用户评价、私人地点和敏感个人信息取得适当许可。不得因内容公开可见就推定已获得同意。
  • **主张：**为价格、结果、排名、引述和前后对比保留证据快照。模拟和重构内容应明确标示。
不要在没有必要时移除真实性元数据。如果平台转码将其移除，仍应在制作档案中保留已签名/源素材和 manifest，并在平台要求时继续使用人类可见的披露信息。

Export platform renditions, not one mystery file

导出平台版本，而不是一个用途不明的文件

Production heuristic — cross-platform working master: 1080×1920, square pixels, progressive H.264 High Profile in MP4, original/native frame rate, AAC-LC stereo at 48 kHz, BT.709 for SDR, and fast-start metadata. These choices align with broad support and YouTube's documented recommendations, but the exact placement contract wins. [S18]
Avoid frame-rate conversion unless required. Avoid baked black bars. Do not upscale poor source merely to satisfy a number; replace or intelligently reframe it.

video rendition
clean master
caption sidecar + caption transcript
cover/thumbnail with profile-grid crop preview
post copy, title, hashtags/mentions, CTA and destination
alt/accessibility text where supported
sponsorship and AI-disclosure settings
music/asset license ledger and attribution
spec verification date and official URL
upload/test status, platform-generated captions checked, UI screenshot
Before public release, upload privately, unlisted, as a draft, or to a test account where the surface permits. Inspect the platform transcode, crop, color, caption timing, UI collisions, cover, sound, and disclosure—not only the local file.
**制作经验法则——跨平台工作母版：**1080×1920、方形像素、progressive H.264 High Profile、MP4 容器、原始/原生帧率、AAC-LC stereo 48 kHz、SDR 使用 BT.709，并包含 fast-start 元数据。这些选择具有广泛的兼容性，也符合 YouTube 公布的建议，但准确的发布位置合同始终优先。[S18]
除非确有需要，否则不要转换帧率。不要添加烘焙式黑边。不要仅为满足参数而放大低质量源素材；应替换素材或进行智能重构图。
为每个平台创建交付包：
text
视频版本
干净母版
字幕 sidecar + 字幕转录稿
封面/缩略图 + 个人资料网格裁切预览
帖子文案、标题、hashtags/提及、CTA 和目标链接
平台支持时的 alt/无障碍文本
赞助和 AI 披露设置
音乐/素材许可清单及署名
规格核查日期和官方 URL
上传/测试状态、已检查的平台生成字幕、UI 截图
公开发布前，应在平台允许的情况下私下上传、设为不公开、存为草稿或上传到测试账户。检查平台转码、裁切、颜色、字幕时序、UI 冲突、封面、声音和披露信息，而不只是检查本地文件。

Technical preflight

技术预检

Verify with a media inspector rather than trusting the export dialog:
  • duration, dimensions, sample aspect ratio, frame rate/time base;
  • codec/profile/pixel format, scan type, color tags, bitrate and file size;
  • audio codec, sample rate, channels, integrated loudness and true peak;
  • audio/video sync and caption end time;
  • first/last frames, unexpected black/frozen frames, offline media, flash frames;
  • spelling, supers, legal lines, URLs, QR codes, and safe-zone overlay;
  • no hidden draft audio, guide tracks, watermarks, or personal metadata.
使用媒体检查工具进行验证，不要依赖导出对话框：
  • 时长、尺寸、sample aspect ratio、帧率/时基；
  • codec/profile/像素格式、扫描类型、颜色标记、码率和文件大小；
  • 音频 codec、采样率、声道数、integrated loudness 和 true peak；
  • 音视频同步和字幕结束时间；
  • 首帧/尾帧、意外黑屏或冻结帧、离线媒体和闪帧；
  • 拼写、上标、法律声明、URL、QR code 和安全区域 overlay；
  • 不存在隐藏的草稿音频、参考音轨、水印或个人元数据。

Create variants that answer a question

创建用于回答具体问题的版本

Separate platform adaptation from experimentation.
  • Platform adaptation may change duration, pacing, caption position, CTA, cover, metadata, music license, disclosure, and even the amount of context.
  • Experimentation should change one meaningful variable when possible: first frame, hook wording, evidence order, duration, CTA, or caption treatment.
Name variants by hypothesis, not 
final-v7
:
text
ytshort-hook-resultfirst-r1.mp4
reels-hook-contradiction-r1.mp4
tiktok-proof-demoearly-r2.mp4
Keep the body identical when testing a hook. Otherwise the result cannot isolate the hook. When the platform does not provide randomized testing, label the comparison observational and note time, audience, distribution, paid support, and sample-size differences.
将平台适配与实验分开。
  • 平台适配可以改变时长、节奏、字幕位置、CTA、封面、元数据、音乐许可、披露方式，甚至上下文信息的多少。
  • 实验应尽可能只改变一个有意义的变量：首帧、hook 措辞、证据顺序、时长、CTA 或字幕处理方式。
按假设为版本命名，不要使用

ytshort-hook-resultfirst-r1.mp4
reels-hook-contradiction-r1.mp4
tiktok-proof-demoearly-r2.mp4
测试 hook 时保持其余内容不变，否则无法隔离 hook 的效果。如果平台不提供随机化测试，应将比较标记为观察性比较，并记录时间、受众、分发方式、付费支持力度和样本量差异。

Measure retention instead of repeating folklore

衡量留存，而不是重复未经证实的说法

Define a funnel appropriate to the platform:
text
eligible exposure → start → chose/continued to view → time held
→ completion/rewatch → meaningful engagement → intended action
Documented fact: platform definitions differ. YouTube exposes “how many chose to view” versus swiped away and audience-retention reports; Instagram reports views, watch time, average watch time, reach, interactions, and follows; TikTok ad reporting defines starts, 2-second views, 6-second views, quartiles, completion, and average play time. Replays are handled differently by metric. [S2][S19][S20]
Therefore:
  • compare clips within the same platform, placement, metric definition, length band, and similar audience context;
  • prefer seconds watched and time-indexed retention alongside average percentage viewed;
  • report uncertainty and sample size; do not declare a winner from a handful of views;
  • separate paid from organic distribution and new from returning audiences;
  • use the primary business or communication outcome as the decision metric, not raw views alone;
  • never compare post-definition-change YouTube public Shorts views directly with old cohorts without qualification.
定义适合平台的漏斗：
text
合格曝光 → 开始播放 → 选择/继续观看 → 保持观看时长
→ 完成/重播 → 有意义的互动 → 预期行动
**已记录事实：**不同平台的定义存在差异。YouTube 会分别提供“how many chose to view”、划走人数和 audience-retention 报告；Instagram 报告观看次数、观看时长、平均观看时长、触达、互动和新增关注；TikTok 广告报告定义 starts、2-second views、6-second views、quartiles、completion 和 average play time。各平台对重播的指标处理方式不同。[S2][S19][S20]
因此：
  • 应在同一平台、发布位置、指标定义、时长区间和相似受众背景内比较短片；
  • 除平均观看百分比外，应优先关注观看秒数和时间索引留存数据；
  • 报告不确定性和样本量；不能仅凭少量观看次数宣布胜者；
  • 应区分付费与自然分发，以及新观众和回访观众；
  • 应使用主要业务或传播结果作为决策指标，而不是只看原始观看次数；
  • 在统计定义变化后，绝不能将 YouTube 公开 Shorts 的新观看次数与旧 cohort 直接比较而不加限定。

Retention-curve diagnosis

留存曲线诊断

Treat these as hypotheses to investigate:
SignalPossible causesRepair test
Immediate clifffirst frame unreadable, promise irrelevant, context missing, wrong audiencetest result-first frame, clearer audience cue, or shorter first line
Drop during setupcontext debt, duplicated narration/text, slow proofmove evidence earlier; remove explanation already visible
Dip at a term or chartjargon, small labels, cognitive overloaddefine one term, simplify chart, extend evidence beat
Spike/replayinterest, surprise, confusion, illegible detail, loopinspect comments and frame readability before calling it success
Strong completion, weak actionsatisfying ending but weak/irrelevant CTA, wrong audience, destination frictiontest a more congruent action and verify destination
Strong early hold, weak completionhook overpromises, middle repeats, payoff delayedalign promise and proof; cut redundant middle
Set a minimum observation window before reading results. Compare against the account's relevant baseline, not a generic “good retention” percentage.
应将以下内容视为需要调查的假设：
信号可能原因修复测试
开头立即断崖首帧难以理解、承诺与受众无关、缺少背景、受众错误测试结果优先的首帧、更明确的受众提示或更短的第一句话
设置阶段流失背景负担过重、旁白与文字重复、证明出现过慢提前展示证据；删除画面中已经可见的解释
在术语或图表处下降术语难懂、标签过小、认知负荷过高解释一个术语、简化图表，或延长证据节拍
峰值/重播兴趣、惊讶、困惑、细节难读或循环播放在认定为成功之前检查评论和画面可读性
完成率高但行动弱结尾令人满意，但 CTA 弱或不相关、受众错误、目标页面存在摩擦测试更匹配的行动并验证目标页面
开头保持率高但完成率低hook 过度承诺、中段重复、回报点延迟对齐承诺和证据；删除冗余中段
读取结果前应设置最短观察窗口。与账户中相关的 baseline 进行比较，不要与笼统的“良好留存百分比”比较。

按以下顺序修复：事实/误导问题 → 同意/权利/披露 → 无法访问的含义 → 技术交付故障 → 音频难以理解 → UI 遮挡 → 结构薄弱/留存问题 → 外观润色。绝不能在关键完整性问题未解决时进行表面润色。

Complete example — 27-second product demonstration

完整示例——27 秒产品演示

Example, not a mandatory formula.
Intent: Produce an organic Instagram Reel and YouTube Short for a calendar app's verified “find a mutual time” feature. Audience: project leads coordinating three or more people. Objective: qualified product interest. Primary metric: saves; guardrails: average seconds watched and profile/site actions.
Inputs and constraints: approved screen recording, product claim verified in current build, no customer data, 27–32 seconds, 9:16, spoken English, open captions plus clean/caption-file master, licensed original music bed.
Promise: “Find the first time everyone can attend without opening four calendars.”
Beat ledger:
TimeJobVoice/textVisualAudio/accessRisk/control
0:00–0:03Show result and audience problem“Four calendars. One meeting. Here is the first time that works.”Messy availability collapses into one highlighted slotUI click + captionCrop contains only fake names; result remains above platform caption area
0:03–0:08Orient“Add the people, then set the window.”Cursor selects three demo participants and date rangeMusic low under speechCursor and fields enlarged for phone; no speed ramp through necessary action
0:08–0:16Prove mechanism“The overlap view removes every conflict.”Conflicts fade; overlap remainsSubtle confirmation SFXLabel animation as product UI, not simulated result
0:16–0:22Show verified result“Tuesday at 2:30 is the first shared opening.”Slot selected; confirmation panelCaptions spell time consistentlyKeep time and button inside current safe overlay
0:22–0:27Resolve and act“Save this for the next scheduling spiral.”Before/after split, app name, save cueMusic resolves; no extra claimCTA is save, matching objective; no unrelated “link in bio”
Platform adaptations: YouTube version uses a searchable title and clean last frame; Instagram version uses a profile-grid-safe cover and verifies Reel UI/caption position. The core proof remains identical. The agent does not claim equal views are comparable because YouTube and Instagram count them differently.
Variant test: Change only the opening from result-first to “Still comparing calendars?” Keep beats 0:03 onward identical. Compare within each platform to the account's similar product-demo baseline.
Expected result: A viewer understands the problem, watches the real workflow, sees the exact result, and receives one congruent action.
Likely failures and repairs: If retention dips during participant selection, shorten pointer travel but retain enough input context to prove the result. If the product UI is illegible, create a guided crop with magnified callout rather than accelerating it. If native and burned captions duplicate, upload the clean version with corrected platform captions or disable one path.
示例，不是强制公式。
**意图：**为日历 app 已验证的“寻找共同时间”功能制作一支自然投放的 Instagram Reel 和 YouTube Short。受众：需要协调三人或更多人的项目负责人。目标：产生合格的产品兴趣。主要指标：收藏；护栏指标：平均观看秒数以及个人资料页/网站行动。
**输入和约束：**已批准的屏幕录制；产品主张已在当前 build 中验证；不含客户数据；27–32 秒；9:16；英语口播；开放字幕，同时提供干净母版和字幕文件母版；使用获得许可的原创音乐底轨。
承诺：“无需打开四个日历，就能找到所有人都能参加的第一个时间。”
节拍清单：
时间任务口播/文字画面音频/无障碍风险/控制
0:00–0:03展示结果和受众问题“四个日历。一次会议。这就是第一个可行时间。”杂乱的可用时间合并为一个高亮时段UI 点击声 + 字幕裁切中仅包含虚假姓名；结果保持在平台字幕区域上方
0:03–0:08建立背景“添加人员，然后设置时间范围。”光标选择三个演示参与者和日期范围音乐在口播下方保持较低音量放大光标和字段以适配手机；不得通过加速省略必要操作
0:08–0:16证明机制“重叠视图会移除所有冲突。”冲突项淡出；重叠项保留轻微确认 SFX将标签动画标记为产品 UI，而不是模拟结果
0:16–0:22展示已验证结果“星期二 2:30 是第一个共同空闲时间。”选择该时段；显示确认面板字幕统一时间写法将时间和按钮保持在当前安全区域 overlay 内
0:22–0:27解决并引导行动“下次再为排时间手忙脚乱时，收藏这个。”前后对比、应用名称、收藏提示音乐收束；不添加额外主张CTA 是收藏，与目标一致；不使用无关的“link in bio”
**平台适配：**YouTube 版本使用可搜索标题和干净的尾帧；Instagram 版本使用适合个人资料网格的封面，并核查 Reel UI/字幕位置。核心证明保持一致。不得声称 YouTube 和 Instagram 的观看次数可以直接比较，因为两者统计方式不同。
**版本测试：**仅将开场从结果优先改为“还在比较日历？”保持 0:03 之后的节拍不变。在每个平台内与账户中相似的产品演示 baseline 进行比较。
**预期结果：**观众理解问题，观看真实工作流程，看到准确结果，并获得一个与内容匹配的行动。
**可能的失败与修复：**如果观众在选择参与者时流失，应缩短指针移动路径，但需保留足够的输入背景以证明结果。如果产品 UI 难以辨认，应创建带有放大标注的引导式裁切，而不是加速播放。如果原生字幕和烧录字幕重复，应上传干净版本并校正平台字幕，或停用其中一种字幕路径。

Complete example — 43-second expert excerpt from source footage

完整示例——从源素材制作 43 秒专家摘录

Example, not a mandatory formula.
Intent: Cut a vertical LinkedIn clip and Reel from a 35-minute interview. The expert explains why a sample-size increase reduced a survey's apparent conversion rate. Objective: correct a common analytics misconception. Primary metric: saves; guardrails: completion and substantive comments.
Selection: Use one continuous answer from source 
interview-a.cam1
, 18:42–19:27, with two pauses tightened. Do not join words across separate answers. Retain the sentence “the earlier sample was only 42 users,” because removing it would make the conclusion misleading.
Structure and shot plan:
  • 0:00–0:05: cold-open conclusion, “The conversion rate fell because the sample got less lucky, not because the product got worse.” Show source speaker, name/role, and concise captions.
  • 0:05–0:13: necessary context, including 42-user sample. Use a simple on-screen 
    42 → 840 respondents
    comparison labeled from the approved transcript/data.
  • 0:13–0:31: mechanism. Alternate speaker with a restrained diagram only when it illustrates sampling variability; do not use unrelated attention footage.
  • 0:31–0:39: implication, “Compare intervals and cohorts, not one headline percentage.”
  • 0:39–0:43: attribution and “Save this before the next dashboard review.”
Audio/caption plan: Repair room tone around pause trims; keep natural cadence. Music is omitted because it adds no communicative value and the source room tone is clean. Upload corrected closed captions and an open-caption variant only where needed. Identify the speaker once; caption 
[laughs]
only if it changes the tone.
Rights/integrity: Confirm interview release, chart-data approval, font license, and corporate endorsement policy. Preserve the transcript, source timecodes, and edit decision list. No synthetic-media disclosure is required for ordinary reframing, color correction, captions, or diagram assistance under the cited YouTube examples, but each target platform's current rule must still be checked. [S12]
Platform adaptations: LinkedIn includes more professional context in post copy, keeps all edges clear, and does not promise immersive-feed placement. Reels uses a 9:16 cover crop and checks current UI safe zones. Both retain the sample-size context.
Analytics repair: A replay spike on the diagram could mean interest or illegibility. Inspect the frame and comments; do not automatically add more cuts. If saves are high but completion is modest, the explanatory core may still meet the objective; test a shorter setup without deleting the 42-user fact.
示例，不是强制公式。
**意图：**从一段 35 分钟的采访中剪出竖版 LinkedIn 短片和 Reel。专家解释为什么增加样本量后，调查表面转化率反而下降。目标：纠正一种常见的 analytics 误解。主要指标：收藏；护栏指标：完成率和高质量评论。
**选择：**使用源文件 
interview-a.cam1
18:42–19:27 中的一段连续回答，并收紧两处停顿。不要跨不同回答拼接词语。保留“earlier sample was only 42 users”这句话，因为删除它会使结论产生误导。
结构和镜头计划：
  • 0:00–0:05：冷开场结论，“转化率下降是因为样本运气变差了，而不是产品变差了。”展示源素材中的说话者、姓名/职位和简洁字幕。
  • 0:05–0:13：提供必要背景，包括 42 位用户样本。使用简洁的屏幕内 
    42 → 840 respondents
    对比，并基于已批准的转录稿/数据进行标注。
  • 0:13–0:31：解释机制。说话者画面与克制的图表交替出现，但仅在图表有助于说明抽样波动时使用；不要加入无关的注意力吸引素材。
  • 0:31–0:39：说明实际意义，“比较区间和 cohort，而不是只看一个标题百分比。”
  • 0:39–0:43：标明来源，并加入“在下次查看 dashboard 前先收藏。”
**音频/字幕计划：**修剪停顿处周围的室内底噪；保留自然语速。由于音乐不增加沟通价值且源素材室内底噪干净，因此不使用音乐。上传校正后的封闭字幕，仅在必要时提供开放字幕版本。标明一次说话者身份；仅当 
[laughs]
会改变语气时才加入该声音提示。
**权利/完整性：**确认采访授权、图表数据批准、字体许可证和企业背书政策。保留转录稿、源时间码和编辑决策列表。对于引用案例中的普通重构图、色彩校正、字幕或图表辅助，不需要合成媒体披露，但仍须核查每个目标平台当前的规则。[S12]
**平台适配：**LinkedIn 在帖子文案中提供更多专业背景，保持所有边缘无遮挡，也不承诺沉浸式信息流发布位置。Reels 使用 9:16 封面裁切，并核查当前 UI 安全区域。两者都保留样本量背景。
**Analytics 修复：**图表处的重播峰值可能意味着观众感兴趣，也可能意味着内容难以辨认。应检查画面和评论，不要自动增加剪切次数。如果收藏量高但完成率较低，解释性核心仍可能符合目标；可测试缩短设置部分，但不得删除“42 位用户”这一事实。
