The smallest useful composition: one text sequence that fades in, sits, fades out. Read this first — every later example just stacks more sequences and properties onto this skeleton.
Movie.init({ canvas, width, height, duration, frameRate, composition }) — the entry pointcomposition.sequences — the list of things on screentype: 'text' with style (set once) and initial (transform applied before keyframes)keyframes with from/to/at/duration/easeat — measured from the end (e.g. at: -0.5 = 500ms before the composition ends)
