Detailed Description
Video transition is a effect of switching between clips.
There are multiple clips on the track. The transition is the transition effect from one video clip to another, and no video transitions can be added between clips with gaps. Currently it supports multiple video transitions including fade, turning, swap, stretch in, page curl, lens flare, star, dip to black, dip to white,push to right, push to top, upper left into.
Each video transition can be set and retrieved via video track (NvsVideoTrack). The default transition is fade.
