What Ltx Video is for
Ltx Video from Lightricks turns a written prompt into a short video clip. Runtime is about 90 seconds and compute is Credits. Modes on this page: Text to Video and Image to Video. It is a clip generator, not a full training-video editor.
Ltx Video is cheap enough that a generation usually fits the free Knowlify plan's credits. A typical run is about 90 seconds.
