Demo: Shorten trim range from 60 seconds to 10 seconds.

Most demo videos aren't very long, and the default demo video is only 10 seconds.

Shorten the maximum trim duration to 10 seconds, to demonstrate transformer functionality more easily, and allow this to be used more easily when trimming short sections of a longer video (ex. to make test clips)
