LTX 2.5 Pro

LTX 2.5 Pro makes the picture and the sound together, so a city can light up on the beat of a track it writes itself, in up to 10 seconds at 1080p. It's also open weights, so you can run it on your own GPU instead, and this page shows what each route gets you.

The prompt

16:9, 10 seconds, 1080p, sound on. A vast futuristic city at night seen in a slow aerial drift above a wide river, glass towers in deep blue and violet, wet streets reflecting neon. The soundtrack is instrumental synthwave at 120 BPM with no vocals, and the city reacts to it. For the first second the skyline sits dark and still under a faint haze while a low, warm synth pad plays alone. At 0:01 the first kick drum lands and a single tower lights up from the ground to its tip in a column of white light. At 0:03 hi-hats come in and rows of windows across the city flicker on and off in rippling waves, in time with the rhythm. At 0:05 the track drops into a big bass and a bright arpeggio, and hundreds of small drones rise from the river and burst into a huge spinning spiral of cyan and magenta light above the water, mirrored in the river below. At 0:08 one final heavy hit flashes the whole skyline bright white for an instant, then every light cuts to black as a short reverb tail fades to silence. Cinematic wide-angle shot, smooth slow camera drift, rich contrast, light film grain.

A night city reacts to a synthwave track it made with the picture: a tower lights up on the first kick, windows ripple with the hi-hats, a drone swarm spirals on the drop, and the skyline flashes white on the final hit. Made with LTX 2.5 Pro.

Beat map

Every beat in the prompt, and what it changed

The prompt wrote the music and the picture together, so the city moves with the track. Every beat arrived in the order the prompt asked for, though most landed a second or two late, so the times below are where each one actually falls. Click a beat to jump to it.

Opening and closing frames

Your product photo opens it, your hero shot closes it

Upload a first and a last frame, and LTX 2.5 Pro fills the move between them, voiceover included. Here, a DAWNLY product photo became a bedroom waking up to the clock's light.

Make the last frame as an edit of the first, so the angle and the room stay the same.

The result

A dark bedroom slowly fills with warm light from an invented sunrise alarm clock, DAWNLY, with a short voiceover. Made from a first and a last frame.

The prompt

16:9, 10 seconds, 1080p, sound on. Image 1 is the first frame and Image 2 is the last frame. A quiet bedroom at dawn. On the oak bedside table, the DAWNLY sunrise clock begins to glow, first a faint amber, then brighter and warmer, its light spreading across the white sheets, the linen curtains and the wall, as the bed and the curtains slowly come out of the dark. The camera holds steady, ending on the clock with the word DAWNLY on its base sharp and readable. A warm, unhurried female voiceover says: "Six-thirty. No beeping, no buzzing. Just light, slowly, like the sun came to you. DAWNLY. Wake up gently." Soft, warm and calm, shallow depth of field, natural textures.

Three prompts, from a rocket stand to the sea floor

Each one is a single paragraph in LTX's own prompting style: what happens, in order, then the camera and the light.

Space

Test fire

A rocket engine roars to life on a desert test stand at night.

Test fire

A rocket engine mounted on its side on a concrete test stand in the desert at night ignites with a blinding white flash. A roaring column of orange and blue flame blasts sideways, raising a huge wall of dust and steam that glows from inside, while sparks scatter across the ground. Floodlights on steel towers light the scene from both sides, and the camera, set low and far back, shakes slightly with the force. Sound: a deep, rising roar and the rattle of the test stand. Wide anamorphic shot, deep black sky, hard light, dramatic contrast.

Shops

The fitting

A tailor flicks through jacket patterns projected onto a customer.

The fitting

In a small, softly lit tailor's shop of the near future, a tailor in her fifties in a gray waistcoat, a measuring tape around her neck, stands beside a customer in his thirties wearing a plain white jacket. With a flick of her fingers, a holographic pattern wraps onto the jacket: first navy pinstripes, then a deep green herringbone, then a bold orange check, each one following the folds and seams as he turns from side to side. He stops on the green herringbone and grins. Sound: a soft chime with each pattern change and quiet shop music. Warm wood interior, bolts of fabric on the shelves, soft key light, medium shot with a gentle push-in.

Sea

The night shift, underwater

Divers repair a glowing data cable on the dark sea floor.

The night shift, underwater

On the dark sea floor at night, two divers in black drysuits with bright headlamps kneel beside a thick undersea data cable that glows with pulses of blue light running along it. One holds the cable steady while the other clamps a new section into place; bubbles stream upward as the clamp locks, and the light pulses flow through the repair and race away into the darkness. Fish drift through the headlamp beams, and sand clouds around their knees. Sound: muffled breathing through regulators, a metallic clunk, a low electric hum. Wide shot that slowly moves closer, deep teal and black palette, soft particles in the water.

Trade-offs

What Pro won't do

Most of these are about the Pro tier specifically, and the Fast tier or the open weights cover some of them. Each one has a way around it.

10 seconds per clip

Pro stops at 10 seconds.

FixSwitch to the Fast tier for up to 20 seconds, or use Seedance 2.5 for 30.

No 4K or HDR on Pro

4K belongs to the Fast tier, and HDR to the open-weights workflows.

FixUse Fast here for a 4K master, or run the open weights for HDR.

No audio upload here

On Predis.ai, LTX 2.5 writes its own sound, so you can't upload a track or a voiceover for it to follow.

FixDescribe the music and the voiceover in the prompt, or run the open weights in ComfyUI, where audio-to-video works.

No character references yet

LTX 2.5 can't yet hold one character across clips using several reference images.

FixStart each clip from the same first-frame image of your character.

The license has a revenue line

Running the open weights yourself is free only for organizations under $10 million in annual revenue.

FixAbove that, use it here or get a commercial license from LTX.

Before you start with LTX 2.5

What is LTX 2.5 Pro?

It's the highest-quality tier of LTX 2.5, an open-weights video model from LTX, the company spun out of Lightricks. It makes 6, 8 or 10-second clips at 720p or 1080p with sound, from text or images.

Pro is tuned for quality and makes up to 10 seconds at 1080p. Fast is quicker and cheaper, and reaches 4K and 20-second clips. Both are in the Predis.ai Model Studio.

Its weights are public on Hugging Face under the LTX-2.x Community License. It's free for organizations under $10 million in annual revenue, while larger companies need a commercial license from LTX.

Yes. ComfyUI supported it from day one with official workflows. ComfyUI also has API nodes that run it on LTX's servers and bill per second.

The weights are free to run yourself if your organization makes under $10 million a year. On Predis.ai it's a paid model you can try in the 3-day trial, which needs a card and moves to a paid plan unless you cancel.
