LTX-2
LTX-2 is an open-source multimodal video foundation model that generates synchronized video and audio from text or image prompts. It produces high-quality motion sequences with native 4K resolution and smooth temporal coherence, making it suitable for creative video generation, production workflows, and audiovisual storytelling.

"positivePrompt": "A cinematic night voyage through a bioluminescent mangrove lagoon under a crescent moon, low camera gliding just above dark glassy water between twisted roots and arching branches. Electric-blue plankton shimmer in the wake, amber fireflies pulse among hanging vines, translucent jellyfish-like spores drift through humid air, and tiny tree frogs chirp from the shadows. A narrow wooden canoe with woven lanterns passes slowly in the midground, carrying a cloaked botanist with reflective instruments and specimen jars. Gentle ripples, subtle leaf movement, curling mist, moonbeams filtering through the canopy, luminous fish darting beneath the surface, distant thunderclouds on the horizon. Natural, immersive synchronized audio: water lapping, insects, frogs, soft wood creaks, faint wind, occasional distant thunder, delicate crystalline chimes from the glowing spores. Ultra-detailed, dreamlike realism, smooth temporal coherence, moody teal-and-amber palette, cinematic depth, atmospheric volumetric lighting.",

"positivePrompt": "Using the provided first frame as the opening shot, create a cinematic night sequence moving gently forward through luminous mangrove channels. The boat continues drifting through glowing water while mist curls between the roots, tiny bioluminescent insects swirl in layered depth, and distant lantern lights shimmer through the fog. Preserve the framing, subject identity, cloak color, and overall composition of the first frame, then add subtle natural motion: water ripples, soft branch sway, drifting spores, faint reflections, and a gradual reveal of a wider hidden lagoon. Moody, immersive, realistic, poetic, high temporal coherence, elegant camera movement, audiovisual storytelling atmosphere.",
