What is LTX 2.5?
LTX 2.5 is Lightricks' long-form video model. One generation runs 5 to 20 seconds, long enough for a whole scene instead of a fragment, at 720p, 1080p, 2K or 4K. It writes from text or animates an opening frame toward an optional closing frame, and every clip comes with a generated soundtrack.
Best on PopNow for: A full runway walk or product reveal in one 20 second take, and high resolution plates that will be reframed or graded later.
Good for
- A full runway pass in one 20-second vertical clip
- 4K plates that survive a grade, a reframe and a slow push
- Shots that start and end on two storyboard frames
What LTX 2.5 does well
Twenty seconds without stitching
An entrance, a pause and an exit fit inside one shot, so continuity is the model's job instead of yours. Few models on PopNow go past 15 seconds in a single take.
4K from the same prompt
Resolution is just a setting. Find the take at 720p, keep the seed, and rerender at 2K or 4K so only the sharpness changes.
Start and end frames
Pin the opening and closing composition and LTX 2.5 builds the move between them, which keeps storyboarded shots on plan.

Prompts that worked on LTX 2.5
Real outputs with the exact prompt we used, and why it worked. Hit Recreate to try the same settings.
Giant iridescent soap bubbles drift and wobble low over the crashing waves on the black-sand beach, the beam of light shifts through the clouds, the figure in the orange parka watches; moody, epic, no text.
Slow, drifting motion (bubbles wobbling over waves) suits long takes: nothing has to happen fast, so the model can keep the scene stable across the whole clip.

How to prompt LTX 2.5
- Pick the length and the shape first: it's 16:9 or 9:16, and length is set at generation.
- Write the shot in time order, keeping the whole arc in one paragraph.
- Find the take at 720p, then rerun the same prompt and seed at 2K or 4K so only the resolution changes.
Settings worth knowing
Everything else has a sensible default, so you can type a prompt and go.
resolution720p · 1080p · 2K · 4K- Output size. Bigger sizes look sharper and cost more.
aspect_ratio16:9 · 9:16- The shape of the frame: wide, square or tall.
duration_seconds5–20s- How long the clip runs. You pay per second.
image_url- The picture to start from.
last_image_url- Optional final frame, so the clip ends exactly where you want.
seed0–2147483647- Reuse the same number to get a repeatable result.
How it compares
Same kind of job, different strengths and prices.
MiniMax H3 covers more shapes and adds reference photos, but stops at 15 seconds. LTX 2.5 is the pick for 20-second takes and native 4K.
Where LTX 2.5 falls short
Only 16:9 and 9:16 are available, and the soundtrack can't be switched off; mute or replace it in your edit.
- Only 16:9 and 9:16 are available; there is no square or 4:3 option.
- The soundtrack cannot be turned off. Mute or replace it in your editor if you need silence.
- Long takes at 4K are among the most expensive renders on the site, so settle the shot at 720p first.
How to use LTX 2.5 in three steps
- Pick LTX 2.5 in the video studio and choose 16:9 or 9:16 and the length up front.
- Write the whole arc of the shot in one paragraph, in the order things happen.
- Render at 720p, then reuse the seed for the 2K or 4K version.

How long can an LTX 2.5 video be?
Between 5 and 20 seconds in one take, chosen in whole seconds.
Is LTX 2.5's 4K native?
4K is one of the model's own resolution settings rather than a separate upscale step, so you request it directly in the same prompt and settings.

No. Every clip includes generated audio. Mute it or swap it out in your editing app.
Which aspect ratios does LTX 2.5 support?
16:9 for landscape and 9:16 for vertical. In image to video, the opening frame decides.
