How creators work

Prompt LTX 2.5 the way Lightricks' guide says

"I stuck the prompting guide into my LLM and use that before generation," one tester wrote. Its four core moves:

01

Establish the shot, then the scene

Start with one or two sentences for the core shot and genre, then layer in lighting, colour and texture.

02

Write the action in present tense

One sequence from start to finish, camera move described relative to the subject.

03

Quote every spoken line

Dialogue in quotation marks, language and accent named, plus ambience and music.

04

Cut with words, 2 to 4 shots

Name each edit, re-establish the new framing and say whether the music carries across.

What people post about

Three things LTX 2.5 does best, according to Reddit

LTX 2.5 talking heads, singing and dialogue

"for talking/singing heads it is way mega much faster lol and it works really great for that," said the top reply when Reddit asked what LTX 2.5 is for. This storyteller talks by candlelight.

  • Put every spoken word in quotation marks inside the description
  • Name the language and accent when they matter
  • Show emotion through face and body, not a label like "sad"

Sharp 1080p detail, up to 4K

"Nothing beats the image quality of LTX 2.5, it's native 1080p video that looks amazing and so fast," one reply said. This storm-sea shot came from a single image, 10 seconds at 1080p.

  • Open with shot scale: wide aerial, macro close-up
  • Keep one lighting logic per shot
  • Finish the winning shot at 1080p or 4K

LTX 2.5 scenes up to 20 seconds long

Reddit names long travelling scenes among its best jobs. This 3D animated morning runs 20 seconds, kitchen to armchair.

  • Write the action as one sequence, in present tense
  • Pick 720p or 1080p for anything past 10 seconds
  • Name each cut: "A hard cut transitions to…"

LTX 2.5 prompts you can copy

"Bro, can you share the prompt?" sits under the best LTX 2.5 posts. Here are two, word for word, beside the video each made.

Earth to the galaxy

@KaminiKamini222

Four timed beats from Earth out to the Milky Way, then one line for the look.

Ultra-8K cinematic video, 10-second duration, 24fps, 2.39:1 aspect ratio, HDR P3 color: [0-1.5s] extreme close-up of Earth — visible curvature, night-side city lights grid, sunlit ocean specular reflection, atmospheric blue halo; [1.5-4s] violent backward acceleration — Earth recedes rapidly, Mars (red-orange, cratered), Jupiter (swirling bands + faint glowing ring), Saturn (sharp edge-on rings), Venus (blinding white disk), Neptune (cobalt-blue with faint vortices) whip past in orbital sequence, each leaving persistent neon-blue/pink motion-streaked light trails with chromatic aberration; [4-7.5s] Milky Way galaxy erupts — ultra-dense starfield (billions of sharp points), luminous purple-pink HII nebulae (Orion, Carina), intense galactic core beams piercing dust; [7.5-10s] camera freezes in deep space — Earth as 3-pixel brilliant blue dot, planets orbiting frame center at accelerated angular velocity, full galaxy background with extreme depth (foreground stars sharp, core softly diffused); style: super-unnatural hyper-realism, volumetric lighting only, strong directional sun key light, god rays through interstellar medium, anamorphic lens flares, extreme bloom (>95%), ultra-sharp 8K detail, zero compression artifacts, no text/UI/spacecraft/atmospheric distortion beyond Rayleigh scattering.

The city above a dark star

@ByronRexMatthe1

One paragraph: the star, the village, its people, then a pull up to the floating world.

Start with a breathtaking aerial view of a vast night sky, a dark dying star hanging below like a black sun, its corona bleeding deep violet and electric blue. Massive volumetric clouds glow from within, indigo, royal purple, midnight blue, shot through with dense god rays and blooming neon light. Smoothly transition into a beautiful futuristic village floating above that dark star: elegant modern white-and-obsidian buildings rimmed with violet neon, cozy houses, lush green gardens, and flowers that fluoresce magenta and cyan. People walk and ride bicycles on soft cloud-covered streets lit by purple lanterns and cascading god rays. Show them enjoying this magical sky world, walking, cycling, gardening, relaxing, their faces and clothes catching the glow. Then slowly pull the camera upward and reveal a massive breathtaking floating civilization stretching across the clouds: bridges, islands, homes, gardens, and futuristic structures, all haloed in dark violet, purple, and blue light, endless night sky around them, the dark star far below throwing dramatic volumetric god rays through every gap. Bright cinematic backlight, realistic shadows, natural human movement, highly detailed environments, dreamy but photorealistic, epic scale, smooth camera movement, aerial drone shots, cinematic depth of field, realistic physics, 8K, ultra detailed, seamless transitions, inspirational fantasy atmosphere. Heavy bloom, rim light, and god rays throughout.

LTX 2.5 vs MiniMax H3, LTX 2.3, FLUX 3 and Wan 3.0

The rivals people set it against most. Prompt each model its own way, then keep the take you would post.

LTX 2.5 vs MiniMax H3

One tester ran the same 10-second 1080p prompt on an RTX 5090: 2m 34s on LTX 2.5, 17m 29s on H3. Here a 10-second 720p clip costs under a third of an H3 clip.

“LTX is about 8 times faster”

Run the same prompt on MiniMax H3

LTX 2.5 vs LTX 2.3

One tester ran the same full-circle camera orbit prompt through both versions, and the 2.5 take came out looking better.

“i tried it back with ltx2.3 director and it did not look this good.”

LTX 2.5 vs FLUX 3

FLUX 3 stops at 1080p on Kavel; LTX 2.5 goes to 4K, and a 10-second 720p clip costs under a fifth as much.

See FLUX 3

LTX 2.5 vs Wan 3.0

Wan 3.0 tops out at 1080p here; LTX 2.5 renders up to 4K, and 10 seconds at 720p costs under two fifths as much.
