AI video clipping is the automated pipeline that turns long content into short clips: transcribe the audio, detect the highest-interest moments, reframe to vertical, add animated captions, and write titles and metadata. What took an editor hours happens in minutes.

It is the engine behind the modern repurposing workflow and the category Nova competes in. The quality bar is moment selection — anyone can cut a video, but finding the segments that actually perform is the hard part.
