LTX 2.5 Review: Long Takes With Sound, Uneven Faces

Pick LTX 2.5 for a long, continuous take with sound baked in; watch faces closely on image-to-video, where likeness can drift across the clip.

Collecting data

LTX 2.5 runs 5 to 20 seconds in a single generation, up to 4K, on two tasks: image-to-video, which takes an opening frame and an optional closing frame, and text-to-video, which writes the whole shot from a caption and returns sound with it automatically. Between 16 and 24 September 2026 we ran our content ladder on both. Nearly everything rendered clean: image-to-video passed L1 Suggestive (lingerie, a slipping strap) through L4 Intense (an intimate scene between two adults) and the L5 Extreme restraint/impact probe on every run we tried; text-to-video matched that except for one L4 Intense run that came back softened. Neither task carries a content declaration field.

The verdict

The catch isn't the content ladder, it's the everyday cases. In our own side-by-side testing against other models on identical prompts, LTX 2.5 handed in two very different outcomes: a two-women slow-dance scene came back clean, well-lit and faithful to the club setting, while a canyon flythrough and a wok-cooking shot both dissolved into heavy colour-artifact distortion. Community reports point at the same unevenness from a different angle: several independent testers flagged that faces can drift across an image-to-video clip in ways the older LTX 2.3 didn't.

Pick it for a long single take with generated sound where you don't need the face to stay pixel-identical throughout. Reach for the still-only, LoRA-tunable LTX 2.3 Spicy family instead when a face has to hold and you're comfortable working without native audio.

Key facts

  • Pass rate: image-to-video rendered every one of our 12 ladder runs clean; text-to-video rendered 11 of 12 clean, with one L4 Intense run coming back softened.
  • Price: $0.09 per second at 720p, $0.13 at 1080p, $0.19 at 2K, $0.30 at 4K, on both tasks. A five-second 720p clip is $0.45; a twenty-second 720p clip is $1.80.
  • Limits: 5 to 20 whole seconds per generation, 720p to 4K, image-to-video takes an optional closing frame, text-to-video writes sound automatically with no field to switch it off.
  • Sources: every scored run is in the LTX 2.5 test report, the scoring rules are on our review methodology page, and the full parameter list is on the LTX 2.5 model page.

What we liked and what held it back

What we liked

  • Twenty seconds in one continuous generation. Most of the video models we test cap out well short of this; here a single request can carry a shot from an opening beat through to an ending without stitching clips together.
  • A closing frame on image-to-video. last_image_url pins exactly where the clip has to land, useful for chaining a sequence — in our own beach-to-bonfire test, the same two people moved from sunset swimwear to a night-time blanket by a fire without us writing the destination in words.
  • Sound comes with the clip, not as an extra step. A street musician prompt returned audible strumming alongside the visual, and a dialogue scene delivered an audible, mostly on-time laugh and lines.
  • Content-ladder results were clean almost everywhere. L1 through L4 Intense and the L5 Extreme restraint/impact probe rendered as asked on nearly every one of our 16-24 September runs.
  • Wardrobe and setting held up on our own sensual scene test. A jazz-club slow dance between two women kept both sequinned dresses and the moody spotlighting intact across the clip.

What held it back

  • Some scenes come back badly distorted rather than wrong. In our own side-by-side test, a canyon flythrough and a wok-tossing shot both turned into heavy orange-and-red colour-artifact blobs with the subject barely recognisable — not a subtle miss, a broken render.
  • Face and likeness can drift on image-to-video. Independent testers reported the same photo rendering as a different-looking person between LTX 2.3 and LTX 2.5; treat a long take as a style-and-motion tool rather than a guaranteed likeness match.
  • Lip sync and mouth shapes are inconsistent. In our own audio tests, judges flagged odd teeth and mouth-shape artifacts in some close-up dialogue clips even where the words and timing landed.
  • No field to turn audio off. Text-to-video generates sound automatically; review the track before you publish; if a scene doesn't need sound, the compute still goes toward producing it.
  • One L4 Intense run softened on text-to-video. Not a hard block, but not a guaranteed pass either — expect the occasional substitution at the harder end of the ladder.

What the clips look like

We don't publish our content-ladder runs; the gallery below is the everyday register, taken from the published, safe-for-work examples on the LTX 2.5 model page.

Sunset to firelight, in one request. Two people on a beach at sunset land, by the closing frame, wrapped in a blanket by a bonfire at night — the prompt only has to describe the passage between the two stills, not the destination.

Candlelight and rising steam. From an opening frame in a candlelit bathroom, she sinks into steaming water, hands dragging through soaked hair — the still supplies the room, the prompt supplies only what changes.

A backwards fall into a pool. She tips backward off a tiled ledge, bubbles rising past her as the camera sinks with her and caustics keep rippling on the columns — the kind of physics beat that usually breaks an animated still.

A twenty-second unbroken crowd crossing. One continuous Steadicam-style move from an arena gate through a packed crowd, written entirely from text with no cuts, at the endpoint's full 20-second length.

A marble staircase, descended in one take. A woman in an emerald silk gown descends an empty opera house's staircase as chandelier light catches the fabric — a full arc of descent, fabric motion and a crane move from a single paragraph.

A cel-shaded ramen stall in the rain. Anime-style, hand-painted backgrounds: a woman ducks under a noren curtain, shakes off an umbrella and sits — style carried entirely by wording, since there's no separate style field.

Prompts that worked

Order the sentence as subject, action, camera, light, then any constraint, and change one variable at a time when troubleshooting a bad take. On image-to-video, let the opening (and closing) frame carry identity and wardrobe, and use the prompt for motion only.

1. A pinned ending, described as passage (image-to-video, closing frame supplied).

text
Cast: one man and one woman. Begin on the two of them on the beach at sunset and end on the supplied final frame: the same two at night wrapped in one blanket by a bonfire, sparks rising. Close: wet swimwear still clinging at sunset, then opening onto firelight.

2. A long take, written as one unbroken move (text-to-video).

text
Cast: a mixed crowd of men and women of different ages and skin tones. The camera stays at chest height in the crush of bodies the whole way through. One continuous 20-second Steadicam take: from the arena gate, through a packed crowd, no cuts.

Weak: describing a fast, complex physical action (a canyon flythrough, a wok toss over flame) with heavy camera movement and fine detail in the same sentence — that combination is where artifacts were most severe. Strong: slow it down, or split a complicated action into fewer simultaneous camera and subject changes.

How far it goes

Between 16 and 24 September 2026 we ran our five-rung content ladder on both LTX 2.5 tasks. Image-to-video rendered L1 Suggestive, L2 Mature themes, L3 Strong and L4 Intense clean on every run, and the L5 Extreme restraint/impact probe rendered clean as well; we did not test the L5 Extreme gore probe on this family. Text-to-video matched that pattern except for one of its L4 Intense runs, which came back softened. Neither task carries a content filter of our own; the page label is Uncensored.

A note on sound and dialogue. Our audio tests on text-to-video found the results uneven rather than uniformly good or bad: a cafe dialogue scene delivered a natural laugh and mostly on-time lines with one inaccurate lip-sync moment; an emotional monologue landed the emotional beat but with a slightly artificial-looking face; a close-up "I missed you" line had good lip sync alongside odd mouth-shape artifacts partway through; a street-musician scene produced audible strumming with somewhat repetitive motion; a glass-shattering sound effect prompt rendered the wrong object (a tumbler rather than a wine glass) with an unclear shatter. Review the audio track on every clip before you publish it — there's no field to disable sound generation if a scene doesn't call for it.

Not tested yet: the L5 Extreme gore probe on either task; whether a supplied closing frame reduces the face-drift issue reported by independent testers; two-men scenes on the ladder; whether slowing down a complex-motion prompt avoids the colour-artifact failures we saw on canyon and wok scenes.

Adults only, in every prompt, still and output. Never depict a real, identifiable person without their consent, and hold the rights to every photo you upload as a frame.

What the community says

Reaction to LTX 2.5 is split along almost exactly the line our own testing found. On the positive side, one Hugging Face user testing on consumer hardware wrote that "The generation speed and visual quality have been very impressive on my RTX 5070 Ti", particularly for landscapes and product shots.

The complaints cluster around consistency. A discussion titled "The character consistency in i2v is a disaster." reported the same reference photo rendering as a visibly different person between LTX 2.3 and LTX 2.5. A second thread, titled "Don't Use LTX 2.5 For Music Videos! Stick To LTX 2.3", pointed at the newer version's text encoder as the source of weaker lip sync for singing and dialogue.

Our own runs land on both sides of that split: the everyday jazz-club and staircase scenes we ran held together well, while the face-drift and lip-sync complaints from the community match what we saw in our own audio tests and side-by-side comparisons.

Alternatives

  • Need a face that holds and don't mind giving up native audio? LTX 2.3 Spicy runs the older, more consistency-tested LTX generation with built-in LoRA presets, from $0.019 a second.
  • Want an open-weight base with a deep local LoRA ecosystem instead? Wan 2.2 trades the long single-take format for a fixed five-second clip at a flat $0.24.
  • Longer takes with multi-shot direction? Wan 3.0 runs up to 30 seconds, priced by the second from $0.045 at 480p.
  • A different open-weight rival with its own community following? MiniMax H3 is the other family independent testers compare LTX against most often.
