Rescript：可在浏览器中运行的免费开源 Descript 替代方案

完全在浏览器中运行是这一类别产品的一个强大差异化优势，因为人们在使用编辑工具时犹豫不决的主要原因，就是需要把自己的原始视频素材上传到他人的服务器。

我希望看到衡量的取舍是：浏览器标签页会在什么情况下撑不住。浏览器内存限制确实存在，处理一段 90 分钟的录制内容与处理一段 5 分钟内容，完全不是同一个量级的需求。实际使用中大致的上限是多少？转录是否也在本地运行，还是该步骤会调用外部服务——因为如果会调用外部服务，那么对于用户最关心的那部分内容，隐私叙事就会悄然改变。

Running fully in-browser is a strong differentiator for this category, since the thing that makes people hesitate about editing tools is uploading raw footage of themselves to someone else's server.

The tradeoff I'd want measured is where the tab gives up. Browser memory limits are real, and a 90-minute recording is a very different ask than a 5-minute one. Do you have a rough ceiling in practice? And does transcription run locally too, or does that step reach out — because if it does, the privacy story quietly changes for the part people care about most.
