FlyCut Caption: An AI-Powered Smart Video Subtitle Generator 154

FlyCut Caption is an open-source video subtitle editing tool that supports intelligent subtitle generation, subtitle editing, and video trimming. It generates subtitles through speech recognition, and you can edit subtitles directly to trim videos—for example, deleting unwanted segments in the subtitle list will also remove the corresponding video segments. It supports batch deletion and can recover accidentally deleted content. It provides real-time preview effects, and clicking on a subtitle segment will jump directly to the corresponding time point. You can also adjust subtitle font size, color, position, background, and stroke style, and see the modification effects in real time.
