This site gives access to the LTX 2.3 video model in two versions: Fast for quick drafts and Pro for higher-quality renders. You start from a written prompt or one image, then shape the clip with settings for duration, frame rate, aspect ratio and the final frame.
Finished videos can be exported from 1080p up to 4K. It works well for testing ideas quickly and then producing a polished version of the same shot once you are happy with it.
