How to write an LTX 2.5 prompt
The LTX 2.5 prompt guide lets you write in screenplay form, and creators on X ran with it. Spell the scene out yourself, the way the r/StableDiffusion regulars advise, rather than leaning on a prompt enhancer.
Set the look once
Era, lens, light and color at the top: "black-and-white 1950s sitcom, soft studio light".
Write it like a screenplay
Shot one, shot two, with the character named in each.
Give every line to someone
Dialogue in quotes after the speaker, then the sound around it.
Test short, render long
2 seconds at 720p to check the beat, then up to 20 seconds at 2K or 4K.
LTX 2.5 without the home GPU and the out-of-memory errors
Run the open model in the cloud, from 720p to 4K, with the sound in and the credits shown first. No three-minute waits on a mid-range card and no out-of-memory errors, the two things the top r/StableDiffusion hands-on thread ran into.
Creative engine
What a clip costs
Seconds times the rate for your resolution, shown before you render.
2 to 20 seconds
2, 4, 6, 8, 10, 12, 16 or 20, in one clip.
720p to 4K
In 16:9 or 9:16, no upscaler step.
Sound in the price
Dialogue, music and ambience at no extra charge.
Ask the SayMaker agent to plan an LTX 2.5 scene and show the credits first. Want to run the same prompt elsewhere? MiniMax H3 sits in the same generator.
LTX 2.5 multi-shot scenes, speed and sound
A whole multi-shot scene in one pass
The launch post on r/StableDiffusion put it plainly: one generation produces several connected shots that hold character identity, lighting, voice and style across the cuts. Write the shots in order and name who speaks in each.
- Faces and voices stay put across cuts
- Upload a still to lock the first frame
Fast enough to iterate
"LTX is about 8 times faster," the most upvoted speed note in the H3 comparison thread said. Lock the idea in a 2-second 720p clip, then render the full version.
- 45 credits for a 2-second test
- The same prompt scales to 20 seconds
Faces that act, and sound that fits
Testers noticed facial motion that looks "more nuanced and natural", and the sound was the part one comparison called far superior. Write the line of dialogue and the emotion behind it.
- Dialogue, singing and ambience in one pass
- Put the spoken line in quotes
LTX 2.5 in the words of people who used it
Public comments and posts from Reddit and X. Every one links back to the original.
LTX 2.5 vs MiniMax H3 and LTX 2.3
vs MiniMax H3 on speed
On the same prompt thread, the top speed comment put LTX at about 8 times faster, and a tester on a 10GB card called it insanely fast.
vs MiniMax H3 on sound and small details
In a 10-second same-prompt test, one reply called the LTX sound far superior, and another said the newspaper stayed consistent, the cigarette smoke looked real and the clothes moved better.
vs LTX 2.3
"A big step up," said r/StableDiffusion, and image to video now keeps the frame format of the still you start from.
vs running it at home
No graphics card to babysit, no out-of-memory crash, no separate upscaler pass: pick 2K or 4K in the generator and the render comes back at that size.
LTX 2.5 FAQ
The questions people ask about it on Reddit, answered for how it runs on SayMaker.
Not on SayMaker. People on r/StableDiffusion wait minutes on a mid-range card or hit out-of-memory errors; here LTX 2.5 runs in the cloud and needs only a browser, with no drivers, no workflow nodes and no download.
Pick LTX 2.5 when you want to iterate fast and hear the result: commenters put it at about 8 times faster and called its sound far superior in one test. Both are in the SayMaker generator, so you can run one prompt through each.
Yes. Native multi-shot was the headline of the LTX-2.5 launch: one generation gives connected shots that keep identity, lighting, voice and style across the cuts. Number the shots in your prompt.
Yes. Pick 2K or 4K in the generator and LTX 2.5 renders at that size, so there is no second upscaling pass and no high-VRAM card to borrow.
r/StableDiffusion called it a big step up, and image to video now keeps the frame format of your starting still.
Write it like a screenplay: the look first, then each shot with the character named, dialogue in quotes and the sounds around it. Spell it out yourself instead of relying on a prompt enhancer.
It is priced per second by resolution. A 6-second clip is 135 credits at 720p, 270 at 1080p, 540 at 2K and 1,080 at 4K; a 20-second 4K clip is 3,600. Sound is included, and a technical failure is refunded.
Yes. Dialogue, music and ambience come out of the same pass as the picture, at no extra charge.
Yes. Upload a still and it becomes the first frame; the prompt only needs the motion, the lines and the sound.
Skip the GPU and render the scene
"The sound quality is very far SUPERIOR!" one tester wrote. Don't leave the scene in your head: hear a test from 45 credits at 720p, see the exact total before every render, take the final to 4K, and a technical failure refunds the run.
