第一步:选题与脚本生成
使用 ChatGPT 进行热门选题调研。给它一个明确的 prompt,让它分析当前 YouTube Shorts 上的热门趋势,然后基于你的目标受众生成 5-10 个选题方向。
选定主题后,让 ChatGPT 撰写一个 30-60 秒的短视频脚本,包含:
- 开头钩子(前 3 秒抓住注意力)
- 核心内容(简洁有力的信息传递)
- 结尾 CTA(引导关注或互动)
第二步:AI 语音合成
将脚本导入 ElevenLabs,选择适合你内容风格的声音。建议:
- 先试听多个声音,选择与内容调性匹配的
- 调整语速和语调参数
- 导出高质量音频文件(MP3 或 WAV)
踩坑提醒:ElevenLabs 免费版有字符数限制,建议先用免费额度测试效果,确认满意后再升级付费版。另外,中文语音质量可能不如英文,建议多试几个声音模型。
第三步:AI 视频生成
使用 Runway Gen-3 根据脚本内容生成视频片段:
- 将脚本拆分为 3-5 个场景
- 为每个场景编写画面描述 prompt
- 生成 4 秒视频片段(Runway 单次生成上限)
- 筛选最佳效果的片段
第四步:剪辑与发布
在 CapCut 中完成最终剪辑:
- 导入所有 AI 生成的视频片段和音频
- 按脚本顺序排列,对齐音频节奏
- 添加自动字幕(CapCut 内置 AI 字幕功能)
- 调整转场效果和整体节奏
- 导出为 9:16 竖屏格式,上传至 YouTube Shorts
Step 1: Topic Research and Script Writing
Use ChatGPT to research trending topics. Give it a clear prompt asking it to analyze what’s currently performing well on YouTube Shorts, then generate 5–10 topic ideas based on your target audience.
Once you’ve picked a topic, have ChatGPT write a 30–60 second short-form video script that includes:
- An opening hook (grab attention in the first 3 seconds)
- Core content (concise, punchy information delivery)
- Closing CTA (prompt viewers to follow or engage)
Step 2: AI Voiceover
Import your script into ElevenLabs and choose a voice that matches your content’s tone. Tips:
- Preview multiple voices and pick one that fits the vibe of your content
- Adjust speaking speed and pitch parameters
- Export a high-quality audio file (MP3 or WAV)
Pitfall warning: ElevenLabs’ free tier has a character limit — test with the free quota first to confirm the quality is right before upgrading to a paid plan. Voice quality varies significantly between models, so try a few before committing to one.
Step 3: AI Video Generation
Use Runway Gen-3 to generate video clips based on your script:
- Break the script into 3–5 scenes
- Write a visual description prompt for each scene
- Generate 4-second video clips (Runway’s per-generation limit)
- Review and select the best takes from each batch
Step 4: Editing and Publishing
Complete the final edit in CapCut:
- Import all AI-generated video clips and the voiceover audio
- Arrange clips in script order and sync them to the audio
- Add auto-generated captions (CapCut has a built-in AI subtitle feature)
- Adjust transitions and overall pacing
- Export in 9:16 vertical format and upload to YouTube Shorts
