Turn a long video into a short cut of the parts worth watching

Build a tool that takes a long video and returns a short video, cut down to the segments that carry the actual content.

Output should be the original footage, not a transcript or a generated voiceover.

Cutting on keyword matches produces something unwatchable. Keeping the moment where a point actually lands, including the setup around it, is the part that has to be good.

Pick one category, such as conference talks or interviews, and do it well before expanding.
