Can I choose how many clips are generated?

Yes. Anywhere from 1 to 10 clips per video.

1. On the zazu dashboard home screen, drop in your video or paste a URL.
2. Click 3 clips in the upload box and pick a number from the list.
3. Click Generate clips.

The default is 3. If you're clipping a long video, ask for more — there's more usable material in 90 minutes than in 10.
