Create one audio-conditioned video with LTX-2.3. Upload a reference image and audio track, then replace the cactus example prompt with your subject, action, setting and camera movement. For a first run, keep 1280 × 720, 24 FPS, 9 seconds and the supplied sampling settings. Supply enough audio after Audio start to cover Duration. Audio start is measured in seconds; negative values count from the end of the track.
