What is the LTX-2.5 Prompt Generator?

The LTX-2.5 prompt generator on this page provides 20 free, professionally crafted prompts for LTX-2.5, the open-weight AI video model released by Lightricks on August 11, 2026. LTX-2.5 is the fastest model in the Lightricks series — optimized for rapid generation, it produces 720p 10-second video clips in approximately 6.8 seconds, with synchronized audio generated from the same prompt in a single pass.

LTX-2.5 launched with day-one ComfyUI support and full open-weight release on HuggingFace under a commercial-permissive licence. Unlike its predecessor LTX-2.3 (which targets maximum quality at 4K/50fps), LTX-2.5 is designed for fast iteration — generate many creative drafts quickly without waiting minutes per clip. It runs on consumer GPUs with 12GB+ VRAM, making it accessible to a wider self-host audience than LTX-2.3 Pro.

Every prompt below is structured for LTX-2.5's fast generation architecture: concise scene descriptions with explicit camera, subject, audio, and duration specifications — the four elements LTX-2.5 responds to most accurately. Paste directly into ComfyUI, fal.ai, Replicate, or the Lightricks API.

How to Write LTX-2.5 Prompts

LTX-2.5 is optimized for speed but still parses structured prompts accurately. Use this four-element framework for consistent results:

[Camera angle + movement] + [Subject + action + timing cues] + [Audio: specific sources + sync points] + [Resolution + duration + quality reference]

LTX-2.5 Strengths:

  • ~6.8s generation for 10-second 720p clips
  • Native audio-visual synchronization in one pass
  • ComfyUI day-one — full workflow ecosystem
  • Runs on 12GB+ VRAM GPUs locally
  • Open-weight, commercial licence, no per-clip fees
  • Improved prompt adherence vs. LTX-2.3

Best Prompt Elements:

  • Keep total prompt under 150 words for best coherence
  • Name specific sounds — "the crack of the anvil," not "ambient sound"
  • Include timing cues for audio sync: "at second 4, the bell rings"
  • Specify camera type: static, tracking, aerial, handheld
  • Always include duration: "8 seconds" or "10 seconds"
  • Add a quality reference: "documentary quality," "commercial style"

1. Street Musician — Rainy Night

Cinematic

A medium shot of a street musician playing acoustic guitar under a neon-lit awning in a rainy city at night. Rain falls steadily on the empty pavement behind them, reflecting red and blue signs. The musician's face is partially lit by a warm lamp above. Camera holds static — no movement. Audio: the soft strum of the guitar, the constant patter of rain on the awning, the distant hiss of a passing car on wet asphalt. Moody, intimate, slightly melancholic. 720p, 8 seconds.

2. Wildfire Smoke — Aerial at Sunset

Nature

An aerial drone shot looking west toward a wildfire at sunset: a dense column of smoke rises from a ridge line into the orange sky, the sun partially obscured, casting the entire valley below in sepia tones. The camera drifts slowly left at constant altitude, revealing more of the smoke plume. Audio: the distant crackling of fire carried on wind, a low atmospheric rumble, silence emphasized by the scale of the scene. 720p, 10 seconds, documentary quality.

3. Coffee Shop — Slow Open

Commercial

A slow push-in shot through the window of a small specialty coffee shop early morning: a barista in a white apron pulls a double espresso shot behind the counter, steam rising from the group head, the interior lit by warm Edison bulbs against the cool blue of the street outside. Camera moves from exterior looking in to just inside the door. Audio: the hiss of the espresso machine, the light clink of cups, soft jazz piano at low volume from inside the shop. 720p, 8 seconds, lifestyle commercial quality.

4. Mountain Trail — First Snow

Nature

A first-person walking shot along a narrow mountain trail just after the first snowfall: fresh snow covers pine branches on both sides, each footstep crunches softly, breath mists in the cold air. The trail rounds a bend to reveal an alpine meadow completely white, a frozen lake visible below. Camera moves at steady walking pace. Audio: the crunch of snow underfoot, the absolute quiet of a snowbound mountain, a single bird call in the distance, the exhale of cold breath. 720p, 10 seconds.

5. Neon Signs — Tokyo Alley

Cinematic

A static shot looking down a narrow Tokyo alley at night: dense kanji neon signs in red, pink, and white stack vertically on both sides, a vending machine glows at the far end. A single umbrella moves through frame from left to right at the mid-distance. The pavement is wet, reflecting the neon in long vertical lines. Audio: the electric buzz of neon signs, a distant izakaya's ambient noise, rain on rooftop surfaces, the soft footstep of the passing figure. 720p, 8 seconds, neo-noir quality.

6. Dog Chase — Park Slow-Motion

Nature

A slow-motion tracking shot following a golden retriever running across an open park at full speed — ears back, tongue out, tail raised. The camera runs alongside at dog height, the background park trees blurring. The dog lunges for a thrown tennis ball at second 6 and catches it. Audio: the rhythmic thud of paws on grass at slow-motion pace, the whoosh of the catch, the joyful bark muffled in the slowed audio. 720p, 8 seconds, filmed at high frame rate reviewed at half speed.

7. Shipyard at Dawn

Industrial

A wide tripod shot of a commercial shipyard at dawn: a massive container ship sits in drydock, scaffolding up its hull, workers beginning the day shift. Two welding torches create small arcs of blue light on the bow. The water in the adjacent dock reflects an orange sky. Audio: the distant metallic ring of work beginning, a foghorn from the working harbor, the creak of scaffolding in a light wind, seagulls above. 720p, 10 seconds, documentary quality.

8. Yoga Pose — Rooftop Sunrise

Lifestyle

A lateral tracking shot of a person holding a tree pose on a city rooftop at sunrise: the subject is in silhouette against the orange sky, buildings of the skyline visible below the horizon line. The camera moves slowly left, keeping the subject centered as the city stretches behind. Audio: the ambient city beginning to wake — a distant siren, a bus, the wind at rooftop height. No music. Calm, intentional, aspirational. 720p, 8 seconds.

9. Blacksmith — Hammer Strike

Craft

A close tracking shot following a blacksmith's hammer as it strikes a glowing orange steel rod on an anvil: sparks burst outward at the point of impact at second 2, the rod deforms slightly, and the smith's hand lifts immediately for the next strike. Camera holds tight on the anvil, slightly below the work surface. Audio: the sharp metallic ring of hammer on anvil precisely synchronized to each visible strike, the roar of the forge fire in the background, the hiss of hot metal. 720p, 8 seconds, craft documentary quality.

10. Volcanic Shore — Lava Entering Ocean

Nature

A wide-angle static shot of active lava flowing off a black rock shelf and entering the ocean at night: the lava glows orange and red against the total blackness of the sea, steam billows upward in a dense white column where it meets the water. The ocean surface flashes orange with each small wave. Audio: the deep crackling and popping of lava cooling, the hiss of steam production, the rhythmic ocean wave underneath, an almost geological silence surrounding all three sounds. 720p, 10 seconds, National Geographic quality.

11. Night Shift — Hospital Corridor

Documentary

A long corridor shot in a hospital at 3 AM: overhead fluorescent lighting, a nurse walks away from the camera into the distance and turns into a ward, a monitor blinks at a nursing station on the left. The corridor is otherwise empty, the only sound is the station's equipment. Camera holds static throughout. Audio: the steady beep of a cardiac monitor at 72 bpm, the squeak of a shoe on linoleum, a distant IV alarm, the deep institutional silence of night shift. 720p, 10 seconds, documentary quality.

12. Skatepark — Aerial Trick

Sports

A slow-motion tracking shot from a low angle inside a concrete skatepark at golden hour: a skater approaches a quarter-pipe, launches into a 360-flip, hangs in the air at the apex for 2 seconds, and lands cleanly. The camera tracks from ground level, looking up at the trick against a warm sky. Audio: the roll of wheels on concrete building to a clack at the launch, silence at the apex, the sharp crack of the landing, the crowd murmur around the park. 720p, 8 seconds, filmed at high frame rate.

13. Ice Melting — Macro Time-Lapse

Science

An extreme macro time-lapse shot of a large ice block melting on a dark surface: water channels form across the surface, bubbles trapped in the ice become visible as layers thin, the block slowly loses its angular edges. Shot from directly above. Audio: the quiet ticking of melting ice — subtle pops as gas bubbles release, the faint trickle of melt water reaching the surface edge, an otherwise silent sound environment. 720p, 10 seconds, accelerated to cover 30 minutes of real melt. Science documentary quality.

14. Market Stall — Spice Vendor

Documentary

A slow tracking shot past a spice market stall in an open-air market: pyramids of saffron, turmeric, paprika, and dried chilis are arranged in open sacks, colour vivid under the midday sun. The vendor's hands are visible scooping powder into a paper bag for a customer. Camera moves at walking pace, slightly below counter height. Audio: the market ambient sound — the clatter of the stall behind, a customer negotiating in Arabic, the crunch of footsteps on the market floor, background music from a neighboring stall. 720p, 8 seconds.

15. Wind Turbine Farm — Dusk

Industrial

A wide aerial shot descending slowly toward a wind turbine farm at dusk: twenty turbines in a grid pattern, all rotating at low wind speed, the sky behind them shifting from deep blue to magenta at the horizon. The camera descends from 300 metres to 100 metres over 8 seconds. Audio: the low sustained whoosh of the turbine blades, the wind at altitude, a deep mechanical drone from the nearest turbine, the ambient silence of the open landscape. 720p, 8 seconds, clean energy documentary quality.

16. Swimming Pool — Underwater Entry

Sports

An underwater camera at the end of a competitive swimming lane captures a swimmer's entry from a racing dive: the swimmer's body enters the water at second 1, arms ahead, creating a long cavity of bubbles that streams behind as they glide forward and dolphin kicks begin. Camera is fixed at 1.5 metres depth, mid-lane. Audio: the explosive surface entry sound, followed immediately by the muted underwater environment — the bubbles trailing, the rhythmic kick, the swimmer's exhalation at second 6. 720p, 8 seconds, sports documentary quality.

17. Origami — Hands at Work

Craft

A close overhead shot of a craftsperson's hands folding a sheet of white washi paper into a crane: each crease is deliberate, the fingers pressing edges flat with precision. The paper rotates as work progresses. No other elements in frame — only hands and paper against a pale wooden surface. Audio: the crisp sound of each paper fold — a clean whisper of fiber compressing, the brush of fingertips smoothing creases, near-total silence otherwise. 720p, 10 seconds, Japanese craft documentary quality.

18. Old Typewriter — Letters at Night

Nostalgic

A close side shot of a vintage mechanical typewriter being used at a desk at night: a single lamp lights the page and the keys, a person's fingers type at a moderate pace, each key clack loud in the quiet room. At second 5, the carriage return bell rings and the carriage slides left. Camera holds static. Audio: each individual keypress synchronized to its visual, the metallic type-bar impact on paper, the carriage bell, the pull of the return lever, the sound of a late-night room. 720p, 8 seconds, nostalgic editorial quality.

19. Fishing Boat — Pre-Dawn Departure

Documentary

A dockside wide shot as a small commercial fishing boat departs just before dawn: running lights on, the engine idling, a crew member casting off the stern line. The boat moves slowly away from the dock, its wake spreading in the calm black water. The sky shows the first pale grey of approaching dawn at the horizon. Audio: the low diesel engine idle, the water slapping gently against the dock pilings, the rope splash as it hits the water, the receding engine note as the boat moves out. 720p, 10 seconds, maritime documentary quality.

20. Fireworks — Single Burst — Slow Motion

Cinematic

A telephoto tracking shot of a single large firework shell bursting at night: the shell rises in the first second, then detonates into a perfect symmetrical chrysanthemum pattern of gold and white sparks that fade over 6 seconds. Camera tracks from the rise through the full fade. Audio at slow-motion pace: the distant thud of the launch at second 0.5 (sound delayed from the visual), the burst crack at second 1, the long slow fade of spark trails, the crowd's distant 'ohhh' from below arriving at second 2.5. 720p, 8 seconds, filmed at high frame rate.

LTX-2.5 Prompting Tips

Do This:

  • Keep prompts under 150 words — conciseness improves coherence at 720p
  • Name specific audio sources: "rain on the awning," "the bell at second 5"
  • State the camera type first: static, tracking, aerial, handheld
  • Include exact duration: "8 seconds" or "10 seconds"
  • Use timing cues for synchronized events: "at second 3, the door opens"
  • Add a quality reference to anchor the visual style

Avoid This:

  • Prompts over 200 words — detail beyond what the clip length can show
  • Vague audio: "ambient sounds" — be specific or the model defaults to silence
  • Multiple distinct scene changes in one clip — LTX-2.5 is best on single scenes
  • Specifying 4K resolution — LTX-2.5's target output is 720p
  • Competing acoustic environments (both indoor reverb and outdoor wind)
  • Omitting camera direction — it defaults to static without specification

Frequently Asked Questions — LTX-2.5

What is the LTX-2.5 prompt generator?

The LTX-2.5 prompt generator on this page provides 20 free, copy-ready prompts for LTX-2.5, Lightricks' open-weight AI video model released on August 11, 2026. LTX-2.5 is optimized for fast, accessible video generation — producing 720p 10-second clips in approximately 6.8 seconds — with day-one support for ComfyUI and availability on HuggingFace. It is the direct successor to LTX-2.3 and continues the Lightricks open-source AI video model family.

How does LTX-2.5 differ from LTX-2.3?

LTX-2.5 is optimized for speed and accessibility where LTX-2.3 prioritized maximum output quality. LTX-2.3 generates 4K video at 50 FPS over longer clips; LTX-2.5 generates 720p 10-second clips in approximately 6.8 seconds, making it the fastest Lightricks model available. LTX-2.5 also ships with improved ComfyUI integration and better prompt adherence on structured scene descriptions. For creators who need fast iteration — generating many drafts quickly before committing to a final render — LTX-2.5 is the right choice. For maximum output resolution, use LTX-2.3 Pro.

How do I run LTX-2.5?

LTX-2.5 model weights are available open-source on HuggingFace under the Lightricks repository with a commercial-permissive licence. ComfyUI support is available day one via dedicated LTX-2.5 nodes. Cloud inference is available on fal.ai and Replicate without local GPU requirements. For local inference, LTX-2.5 runs on consumer GPUs with 12GB+ VRAM — lower requirements than LTX-2.3 Pro, which needed 24GB. The ComfyUI workflow is the recommended path for iterative creative work.

How do I write good prompts for LTX-2.5?

LTX-2.5 responds best to structured scene descriptions that cover four elements: (1) Camera angle and movement — 'static shot,' 'slow tracking from left,' 'aerial descending'; (2) Subject and action with timing cues — 'at second 4, the wave breaks'; (3) Audio environment — name specific sound sources and their spatial relationships; (4) Quality reference and duration — '720p, 8 seconds, documentary quality.' Keep prompts under 150 words for best coherence. The LTX model family handles synchronized audio natively, so describing audio in detail is worth the effort.

Does LTX-2.5 generate audio?

Yes. LTX-2.5 inherits the Lightricks model family's native audio-visual generation architecture. Audio and video are generated from the same text prompt in a single pass — the model produces synchronized sound based on your description of the acoustic environment. To get the best audio results, describe specific sound sources ('the crack of a hammer on steel'), spatial positioning ('the crowd noise from behind the camera'), and timing relationships ('the thunder arrives 1.5 seconds after the lightning'). Vague audio descriptions like 'ambient sound' will produce generic results.

How does LTX-2.5 compare to Wan 3.0?

LTX-2.5 and Wan 3.0 (Alibaba Tongyi Lab, August 2026) are both open-weight video models released in the same month. The key differences: LTX-2.5 generates clips up to 10 seconds at 720p in ~6.8 seconds — optimized for speed; Wan 3.0 generates clips up to 30 seconds at 1080p, prioritizing longer-form output and cinematic quality. LTX-2.5 includes native audio generation; Wan 3.0 generates silent video. For fast iteration and creative drafts with synchronized audio, LTX-2.5 is the better choice. For longer, higher-resolution cinematic clips, Wan 3.0 leads.
