What Live Portrait is for
Live Portrait animates a still into a short video clip. Upload the starting frame, describe the motion, and the studio returns a clip in about 90 seconds (Credits). Available modes: Video and Image.
Live Portrait is cheap enough that a generation usually fits the free Knowlify plan's credits. A typical run is about 90 seconds.
Pick Live Portrait for image to video at Credits and ~90s. Compare it with Ai Avatar, Argil Avatar on the related cards below if you need a different look, speed, or input type.
