TikTok 近期发布了一系列新的工具和功能，包括AI驱动的智能剪辑（Smart Split）和AI大纲（AI Outline）。Smart Split能够将超过一分钟的长视频自动剪辑、重构、添加字幕和转录成多个短视频，特别适合处理播客和长视频内容。AI Outline则能为创作者提供视频标题、话题标签、开场白和内容大纲，帮助创作者优化内容。这些新工具旨在简化创作者的工作流程，提升内容创作效率，并进一步巩固TikTok在短视频领域的领先地位。这些AI工具的推出也反映了社交媒体平台普遍对AI技术的重视和投入。

💡 **AI智能剪辑（Smart Split）简化长视频内容再创作**：TikTok推出的Smart Split是一款AI驱动的编辑工具，能够将一分钟以上的长视频（如播客、长视频论文）自动剪辑、重构、添加字幕并转录成多个短视频。创作者只需上传长视频并选择希望剪辑的部分，即可由AI自动完成后续处理，极大地节省了创作者在处理长内容时进行繁琐剪辑的时间。

📝 **AI大纲（AI Outline）助力内容策划与优化**：AI Outline是另一项AI驱动的工具，它能为创作者提供视频标题、话题标签、吸引人的开场白以及内容大纲。创作者只需输入提示或选择主题，即可获得一个将视频分解为六个部分的大纲。该工具还允许创作者对AI生成的内容进行编辑和优化，以更好地适应其受众和风格。

🚀 **AI工具的广泛应用与平台趋势**：TikTok此次推出的AI工具，如Smart Split和AI Outline，是其持续投入AI技术以提升用户体验和创作者效率的体现。这与当前社交媒体平台普遍拥抱AI的趋势一致，旨在通过技术创新来优化内容生产和分发，满足用户对多样化、高质量短视频内容的需求。

TikTok just dropped a whole host of new tools and features — including new monthly rewards and so, so much AI.

Long videos are great for YouTube, but they might not be ideal for short-form video. Enter: Smart Split, an AI-powered editing tool that takes your longer videos — think podcast videos and hour-long video essays — and clips them into shorter videos.

"If you've ever spent hours trimming down podcasts into clips… this one is for you," Kim Farrell, the global head of creators at TikTok, said at TikTok's 2025 U.S. Creator Summit.

The tool, which is available globally on TikTok Studio Web, automatically clips, reframes, captions, and transcribes users' longer videos into multiple short videos. To use the tool, creators still need to do a bit of work. You'll have to upload videos that are longer than one minute and select which parts you want clipped. Then, either decide how long you want the videos to be or let Smart Split automatically choose the length. You can also choose the caption formatting and reframe the content if necessary.

The platform also launched AI Outline, an AI-powered tool that gives creators video titles, hashtags, hooks, and outlines. Simply enter a prompt or select a topic on Creator Search Insights to get an outline that breaks a video down into six parts. After you get the AI response, you can ask it to edit the response — i.e., ask for it to give you another hook option or make the script better fit your audience. AI Outline is available for creators 18 years or older in the U.S., Canada, and select markets.

It's not surprising that TikTok would continue to lean into AI — it seems every social media platform is. Earlier this month, Twitch announced a new AI-powered tool that automatically creates clips from livestreams, kind of like the Twitch version of Smart Split. Meta has its own array of AI-powered tools for creators, like AI tools on Edit, AI Studio, and the "infinite slop machine" that is Meta AI's Vibes.
