Make a video shorter, or give it more depth

Sometimes a video is too long for the platform; sometimes it is too thin for the topic. Set a target length and the summarizer rewrites the narration to fit, then rebuilds the scenes and captions around the new script. Elaborate works the other way, adding detail to lengthen a video that skims its subject.

Use videos from your library or upload your own, and keep both versions.
