Create 4K Videos with LTX 2.5

Use LTX 2.5 on Ezier to create 4-20-second videos from text or one start image, choose Fast or Pro mode, render at 1080p or 4K, and generate audio in the same workflow.

Turn one brief into a finished LTX 2.5 shot sequence

Plan the action in chronological order, keep repeated subjects recognizable across connected shots, and write sound into the same scene description. Then choose the Ezier settings that match the way you want to review the result.

Prompt example

Create a 6-second photorealistic motocross chase on a flooded dirt trail beneath an overcast sky. Keep the same rider in a red-and-white helmet, dark blue protective gear, mud-streaked trousers, boots, and compact backpack on the same dirt bike. Place the camera extremely low and close behind the rear wheel as the rider accelerates through successive puddles, sending heavy arcs of brown water and mud toward the lens. Let the rider shift weight naturally while the rear suspension compresses, the tire finds traction, and the trail recedes between scrub-covered banks. Pull slightly wider for the final beat as the bike continues straight through the deepest rut. Preserve the rider, gear, bike geometry, trail direction, cloud cover, and mud buildup across the shot. Use grounded wheel rotation, realistic spray physics, controlled lens splatter, and directional motion blur. Visual-only output with no dialogue, captions, logos, extra riders, changing equipment, warped wheels, or cuts to a different location.

How to use LTX 2.5 in Ezier

  1. 01

    Select LTX 2.5

    Confirm that LTX 2.5 is active in the model selector before choosing mode, resolution, duration, ratio, or generated audio.

  2. 02

    Choose text or one start image

    Write a scene from scratch, or attach one image when the opening subject, construction, framing, or lighting must begin from a fixed visual source.

  3. 03

    Describe shots in chronological order

    State each action, recurring subject detail, camera angle, transition, lighting cue, and sound event in one clear sequence instead of a loose list of visual adjectives.

  4. 04

    Set the output and generate

    Choose Fast or Pro, 4-20 seconds, 1080p or 4K, 16:9, 1:1, or 9:16, seed when useful, and generated audio. Review the credit estimate, then generate.

Direct continuity, image motion, and sound with LTX 2.5

LTX describes 2.5 as a stronger open-weights foundation for multi-shot continuity, cleaner motion, and synchronized audio-video work. In Ezier, those strengths begin with a prompt or one start image and the controls visible in the generator.

Keep subjects coherent across connected shots

Official LTX 2.5 materials emphasize native multi-shot continuity across character, environment, lighting, and voice. Repeat the few identity details that must survive each cut, then give every shot a distinct purpose.

Anchor handmade detail with one start image

Use image-to-video when material, silhouette, arrangement, or opening composition matters. Separate the details that must stay fixed from the motion that should develop after the first frame.

Make synchronized sound part of the action

LTX 2.5 generates audio and video together. Name visible sound sources, their timing, distance, and acoustic space so effects, ambience, music, or dialogue can be judged against the picture.

LTX 2.5 settings currently available in Ezier

Use the current Ezier controls to choose duration, resolution, and performance mode. LTX 2.5 also brings automatic duration, precise video editing, native 4K HDR, RAW workflows, and open weights for custom production pipelines.

4-20s
Duration in EzierChoose a short run for one controlled action or use the longer range for connected shots with an intentional finish.
1080p / 4K
Resolution choicesUse 1080p to test direction at a lower displayed credit estimate, then select 4K when the approved sequence needs more output detail.
Fast / Pro
Performance modesUse Fast for rapid creative iteration and Pro when the selected direction needs a higher-fidelity generation pass.

Draft the shot order before adding style language

First make the sequence unambiguous: subject, action, angle, cut, and finish. Add lighting, texture, and mood only after the timeline reads clearly.

Use Fast mode to isolate prompt problems

Test one variable at a time—shot order, camera path, subject identity, or audio timing—so the next change has a clear reason.

Reserve 4K for a direction worth keeping

Resolution cannot repair unclear staging or continuity. Confirm motion and composition at 1080p before spending more credits on the higher-resolution pass.

Write sound at the moment it happens

Place a sound beside its visible cause in the prompt. This is clearer than collecting every effect, ambience, and line of dialogue at the end.

What LTX 2.5 brings to the workflow

Move from text or an image to synchronized video, build connected shots with stronger continuity, edit real footage with precise direction, and prepare high-resolution results for professional finishing.

LTX 2.5 is an open-weights audio-video foundation model

LTX presents version 2.5 as a foundation teams can run, fine-tune, and deploy. Its official release highlights cleaner motion, native multi-shot continuity, stronger prompt adherence, automatic duration, and professional finishing options.

Create from text, an image, or real footage

LTX 2.5 combines text-to-video, image-to-video, and precise video editing in one model family. Use a written brief to build a scene, anchor motion with visual material, or direct targeted changes to existing footage.

Generate high-resolution video with flexible timing

LTX 2.5 supports automatic duration and native 4K HDR output. In Ezier, choose 4-20 seconds, 1080p or 4K, and 16:9, 1:1, or 9:16 based on the sequence and final placement.

Balance speed, fidelity, and synchronized audio

Use Fast for rapid iteration or Pro for a higher-fidelity pass. A seed can help repeat a direction, while generated audio keeps dialogue, effects, ambience, and music connected to the picture.

LTX 2.5 in Ezier

Test the sequence in Fast mode, then finish the strongest take in Pro

Start with the shortest useful duration, verify the subject, shot order, camera path, and sound timing, then move to Pro or 4K only when the creative direction is worth the higher credit estimate.
