短视频前 3 秒决定留人曲线，剪辑救不了烂开头。Hook 必须视觉冲击——模式打断、好奇缺口、强对比——而且要在第一拍内完成。下面这套 Prompt 强制三种之一 + 紧凑的 2-3 秒时长，模型不能再”慢慢铺垫”。完整短视频生产闭环参考AI 短视频 Prompt。

这套 Prompt 适合用在哪

  • TikTok / Reels / Shorts 开头——算法看前 3 秒
  • 后期要剪进长一点的 Sora / Veo 视频的 hook 片段
  • 留存就是唯一指标的广告创意
  • 不同开场形态的 A/B 测试
  • 没主持人的 B-roll 账号

1. 模式打断

short-form video hook, pattern interrupt opening, sudden close-up of unexpected object filling the frame, hard cut from black, no slow zoom-in, 9:16 aspect, 2 seconds, energetic style, motion blur on cut

2. 好奇缺口（主持人）

short-form video hook, presenter looks directly into camera and asks a curiosity-gap question that contains a specific number, hand-held subtle shake, quick cut to context shot showing the thing the question refers to, 9:16, 3 seconds total

3. 视觉对比

short-form video hook, dynamic split-screen of two contrasting visuals (before / after, expected / actual, them / me), fast inward zoom on the right panel, no text overlay, 9:16, 2 seconds, high color contrast

4. 留白爆点

short-form video hook, opens on near-empty frame with one tiny element in negative space, sudden whip-pan reveals the full scene, audio sting on the reveal, 9:16, 2.5 seconds, cinematic but punchy

5. 动作中段冷启

short-form video hook, cold open in the middle of an action with no setup (someone already running, hand already mid-motion, object already falling), camera locks on the action 0.5s in, 9:16, 3 seconds, raw documentary style

6. 屏幕字幕模式打断

short-form video hook, full-frame bold text appears for 1 second over a stylized background, text contains a specific number and a counter-intuitive claim, text snaps off as a hard cut reveals the presenter, 9:16, 3 seconds, mobile-readable font size

7. POV 冷启

short-form video hook, first-person POV opening with hand or object entering frame, suggests the viewer is the one experiencing this, audio cue (footsteps, door, breath) starts before visual, 9:16, 2.5 seconds, slight motion blur for realism

8. 数据冲击

short-form video hook, screen opens with a single shocking statistic in 80pt text, stat fades in 0.3s, voiceover speaks the stat as it appears, hard cut to b-roll relevant to the stat at 1.5s, 9:16, 3 seconds total

9. 文字提问 hook

short-form video hook, opens with a one-line question superimposed on a moving background loop (clouds, water, traffic), question implies the answer is counter-intuitive, no presenter, voiceover delivers the question with deliberate pause, 9:16, 3 seconds

10. 单物 hook

short-form video hook, single object on a clean background, dramatic lighting, slow rotation for 1s then hard cut to the object being used / broken / transformed, ASMR-grade sound design on impact, 9:16, 3 seconds, product-shot aesthetic

11. 失败时刻 hook

short-form video hook, cold-opens on someone visibly failing at the thing the video is about (a fall, a spill, a misfire), camera holds the failure for 1s without comedy music, then cuts to the title card, 9:16, 2.5 seconds, honesty-first tone

12. 声音先行 hook

short-form video hook designed for audio-first feed (TikTok with sound on by default), opens with a 1-second sound (laugh, scream, sigh, distinct line of dialog) over a black or single-color frame, visual reveal happens at 1s synced to the audio peak, 9:16, 3 seconds

怎么继续打磨

每个概念出 3-5 条 hook，然后在手机上看，不是在电脑上看——留存是观众用的那个设备决定的。Hook 要配后续 viral-shorts 故事弧，让剩下的片段兑现开头承诺。比例和投放面选择参考 AI 视频比例指南，9:16 vs 4:5 vs 1:1 怎么选都在里面。

容易踩的坑

  • 开头慢（1 秒以上没事发生——算法已经把你算丢了）
  • 没视觉对比——开头和信息流融成一片
  • Hook 超 3 秒——留存掉点已经发生
  • 比例错配（9:16 平台上放 16:9 hook）
  • 字幕太小——手机上动着看不清，小于 60pt 全砍掉
