Most Biteable 1.0 scenes are able to be shortened by around 3 seconds long. To shorten a scene: Click the stopwatch icon below the duration section, and then click short version- it's that easy!
At the moment you are unable to extend a Biteable scene on 1.0, however it is something we are looking into.
In 3.0, however, scene duration is more customizable! You can lengthen or shorten either your captions or your backgrounds by grabbing on the vertical white stripe on the right side of the element and dragging it in and out!🤖
