yt-short-clipper

Windows desktop app that turns long-form YouTube videos into 9:16 short-form clips — AI highlight detection, face-tracking portrait reframe, and word-by-word captions. Maintained by jipraks on GitHub, where it has earned 986 stars from the community.

It's actively developed around ai-video, content-creation, ffmpeg, and is a solid reference for anyone building with these tools.
