隐私向 AI 拆条工具（Windows）：视频文件留在你的电脑上
如果你要把播客、课程或访谈切成短视频，又不想把整段成片传到别人的服务器，需要的是一款 privacy AI video clipper：在本机完成拆条，视频文件不上传。
ClipSparkSoft 是独立的 Windows 桌面软件，由个人开发者张鹏运营。导入、本地转写、挑高光、加字幕和导出都在你的电脑上完成。视频文件不上传。
什么是 privacy AI video clipper
云端拆条工具通常先上传整段视频，再在对方服务器上转写和出片。隐私向做法反过来：成片留在磁盘上，软件在本机读文件、出短片段。
在 ClipSparkSoft 里大致是这样分的：
- 视频文件：不上传，始终在你的 Windows 电脑上。
- 转写：用本地 Whisper，不把音视频交给云端转写。
- 高光分析：需要时只把文字稿发给 Gemini，不传视频文件。
所以请写清楚「视频文件不上传」，不要说成「完全离线」或「任何数据都不出电脑」——分析步骤会用到文字稿。
适合谁
- 播客、课程、会议或访谈录像，要切成 Shorts / Reels / TikTok
- 在 Windows 上剪辑，暂时不需要 macOS 或手机版
- 在意素材离开自己的电脑，或嫌整集上传又慢又占额度
本机怎么跑通
- 把本地长视频拖进 ClipSparkSoft
- 本机转写（Whisper）
- 根据文字稿挑高光（分析只传文字稿）
- 需要的话加字幕，再导出 9:16、16:9、1:1 或 4:5
下面这条演示是一条长视频在本机被切成几条短视频。
机器大概要怎样
目前没有单独的最低配置清单。按常见中端 Windows 电脑可以这样理解：
- Windows 10 或 Windows 11（64 位）
- 大约 8 GB 内存（16 GB 更稳）
- 近几年的 Intel / AMD 中端 CPU
- 给软件、模型和成片留出数 GB 磁盘空间
- 不强制独立显卡；有独显通常更快，核显也能跑
更长或更高码率的片子会更吃时间，以你机器上的实际导出为准。
和云端拆条怎么选
| 隐私 / 本地拆条 | 云端拆条 | |
|---|---|---|
| 视频文件 | 留在你的 PC | 先上传到对方服务器 |
| 转写 | 本机 Whisper | 通常在云端完成 |
| 分析用的内容 | 需要时只传文字稿 | 往往基于已上传的媒体 |
| 系统 | ClipSparkSoft：仅 Windows 桌面 | 多为网页，任意设备浏览器 |
若你接受上传、又想多设备网页操作，云端工具更合适。若优先「成片不出电脑」，选本地隐私向拆条。 若你在找 Opus Clip 一类产品的对照，见 Opus Clip alternative 对照页。

Privacy AI Video Clipper for Windows — Video Files Stay on Your PC
If you turn podcasts, lessons, or interviews into short clips and do not want the full recording uploaded to someone else’s servers, you need a privacy AI video clipper: cutting happens on your machine, and the video file is not uploaded.
ClipSparkSoft is a separate Windows desktop app, operated by Peng Zhang, an individual developer. Import, local transcription, highlight picks, captions, and export run on your PC. The video file is not uploaded.
What a privacy AI video clipper is
Cloud clippers usually upload the whole file, then transcribe and cut on their servers. A privacy-first workflow flips that: the footage stays on disk, and the app reads it locally to produce shorts.
In ClipSparkSoft the split is:
- Video file: not uploaded — it stays on your Windows PC.
- Transcription: local Whisper — audio/video is not sent to a cloud speech service.
- Highlight analysis: when needed, only the transcript text is sent to Gemini — not the video file.
Say “the video file is not uploaded.” Do not say “fully offline” or “nothing ever leaves your PC,” because the analysis step can use the transcript.
Who it is for
- Podcasts, courses, meetings, or interview recordings headed for Shorts / Reels / TikTok
- Editors on Windows (macOS and mobile are not available yet)
- Anyone who prefers footage to stay on their machine, or who dislikes uploading a full episode for speed or quota reasons
How a local run works
- Drop a local long video into ClipSparkSoft
- Transcribe on the PC with Whisper
- Pick highlights from the transcript (analysis sends text only)
- Add captions if you want, then export 9:16, 16:9, 1:1, or 4:5
This recording shows one long video cut into short clips on the PC.
Rough PC expectations
There is no separate minimum-spec sheet yet. Treat a typical mid-range Windows PC as a practical baseline:
- Windows 10 or Windows 11 (64-bit)
- About 8 GB RAM (16 GB is more comfortable)
- A recent mid-range Intel or AMD CPU
- Several GB free for the app, models, and exports
- No dedicated GPU required; a discrete GPU usually helps, integrated graphics can still run
Longer or higher-bitrate files take more time. Trust what you see on your own machine.
Local privacy vs cloud clippers
| Privacy / local clipper | Cloud clipper | |
|---|---|---|
| Video file | Stays on your PC | Uploaded to their servers first |
| Transcription | Local Whisper | Usually in the cloud |
| What analysis uses | Transcript text when needed | Often based on uploaded media |
| System | ClipSparkSoft: Windows desktop only | Often web, any browser |
If you are fine uploading and want a browser on every device, a cloud tool fits better. If keeping the file on your PC comes first, use a local privacy clipper. For a direct Opus Clip–style comparison, see the Opus Clip alternative page.
Free plan and Pro
There is free monthly quota every month — open the app for the exact limits. Pro removes the watermark and raises the limit. Prices match the app: $9.9 per month or $99 per year. See pricing.
