Key Features of LTX-2.3 AI Video Generator
LTX-2.3 es un modelo de vídeo con IA avanzado, diseñado para generar escenas completas con un gran control del prompt, imágenes detalladas y audio sincronizado.
Generación sincronizada de audio y vídeo
LTX-2.3 generates visuals and audio together so that sound, dialogue, and motion are aligned from the start. When a character speaks, lip movement matches the voice, and sound effects occur at the right moment in the scene. This removes the need to add audio separately or manually sync it later. It also helps create more natural pacing, since movement and sound are generated as part of the same sequence rather than stitched together afterward.
Try it NowMayor fidelidad al prompt y control de escena
LTX-2.3 handles detailed prompts with multiple elements, including subject, environment, motion, and camera direction. You can describe how a scene should unfold, such as a slow camera pan or a subject moving through a space, and the model follows those instructions more closely. It also supports multiple reference images, including defining a starting frame and an ending frame, allowing you to guide how a scene begins and how it transitions over time.
Try it NowUltra-HD 4K Output with Fast Generation
LTX-2.3 supports video generation up to 4K resolution while maintaining fast production speeds. You can generate clips ranging from 6 to 20 seconds long without long rendering delays. Even at higher resolutions, the model is optimized for quick iteration, making it possible to test different scenes, angles, and variations without slowing down your workflow.
Try it NowGeneración de vídeo vertical 9:16 real
LTX-2.3 generates vertical videos natively in a 9:16 format instead of cropping from a horizontal frame. This means scenes are composed specifically for vertical viewing, with subjects framed correctly and motion designed for that orientation. Because the model is trained on portrait-style data, the output feels natural rather than compressed or reframed. This makes it easier to create content for mobile platforms where vertical video is the default, without needing to adjust composition after generation.

Prompt y fotogramas de referencia
Escribe un prompt estructurado que incluya sujeto, entorno, movimiento y cualquier audio o diálogo. También puedes subir una o varias imágenes de referencia, incluyendo la definición de los fotogramas inicial y final.
Generate and Refine
Select your desired aspect ratio, duration (6 – 20 secs), and resolution (up to 4K) and generate your video. Adjust your prompt to refine specific elements like movement, scene composition, or audio alignment.
LTX-2.3 is Built for Controlled, High-Quality Video Creation
Crea escenas cinematográficas, vídeos hablados, imágenes animadas y contenido para redes con resultados detallados, audio sincronizado y control estructurado.
Generación de escenas cinematográficas con dirección de arte
LTX-2.3 works well for creating short cinematic scenes where motion, camera direction, and timing need to feel intentional. You can define how a scene starts and ends using reference frames, then guide the motion in between. This makes it possible to generate sequences that feel directed rather than random. With support for up to 4K output and longer clip durations, these scenes can be used for more polished visual storytelling or concept previews.
Try it NowHigh-Quality Video from Reference Frames
LTX-2.3 can take lower-resolution or static reference images and turn them into smooth, high-quality video outputs. When you provide starting and ending frames, the model fills in motion between them while improving overall visual quality. It naturally enhances detail, smooths transitions, and maintains consistency across frames, so the final video looks sharper and more complete than the original inputs. This makes it useful when working with rough assets or early-stage visuals, since you can generate polished video outputs without needing perfectly prepared source material.
Try it NowTalking Characters and Voice-Driven Videos
Puedes generar vídeos en los que los personajes hablan con movimiento de labios sincronizado y audio a juego. Como la voz y las imágenes se crean juntas, la sincronización entre el habla y el movimiento resulta natural. Esto es útil para explicativos, presentaciones cortas o contenido sencillo protagonizado por personajes. Puedes controlar el tono y el ritmo a través de tu prompt y generar clips completos sin necesidad de herramientas de voz o edición aparte.
Try it NowImage-to-Video & Frame-to-Video Animation with Stable Subjects
LTX-2.3 can animate still images into moving scenes while keeping the subject consistent. You can use multiple reference images to guide different parts of the sequence, such as defining how a scene begins and ends. The subject remains stable across frames, so it does not warp or lose structure as the video progresses. This makes it easier to turn static visuals into controlled animations with clear transitions.
Try it NowShort-Form and Vertical Video Content
The model can generate videos in vertical 1080×1920 format natively without giving a cropped look, making it suitable for social platforms. You can create short clips within the 6 to 20 second range that are optimized for mobile viewing. Because generation is fast even at higher resolutions, it becomes easier to produce multiple variations of the same content for testing and distribution.
