Chain the clips. Watch the stitch.
Give Viddio a scene, a number of clips and a seed. It paints the clips in your browser the way the Preview does and shows that every clip starts where the last one ended.
A look-alike of the Preview, in your browser. In the app, the Preview paints each clip from your words and a seed, and every clip starts on the last frame of the one before. This page paints the same kind of sample here. It is real, and it is not a video model. The same words and seed give the same clips. Nothing is uploaded and nothing is saved.
