Miaomu (SmartSub) is a powerful open-source audio and video subtitle generation and multilingual translation tool that lets you completely say goodbye to CapCut membership subtitle features. It supports multiple audio and video formats, and all processing is done locally to ensure data privacy and security. The software has been repeatedly tested over many days and has been proven to work stably. For those who frequently repost overseas videos or need to quickly create subtitles, it is a very practical and efficient choice. You can generate video subtitles with one click and choose different high-precision models to improve recognition accuracy.

This tool is completely free and open-source, supports GPU acceleration, and can still be used normally even without a dedicated graphics card, though processing speed will be slightly slower. The speech recognition to subtitle feature requires your own API key, but it also supports pure local subtitle generation without an API, meeting the needs of different scenarios. It also has a built-in timeline calibration feature to ensure subtitles are perfectly synchronized with the visuals. By mastering Miaomu, you will have a completely free and powerful local subtitle workstation, greatly improving video production efficiency.
