LTX-2.3 Image-to-Video
LTX-2.3 is a significant update to the LTX-2 model, featuring improved audio and visual quality with enhanced prompt adherence. As a DiT-based (Diffusion Transformer) audio-video foundation model, it animates your input image into a high-fidelity video with synchronized audio generated in a single pass.
Why Choose This?
-
Improved quality
Enhanced audio and visual quality compared to LTX-2, with better prompt adherence and more coherent outputs.
-
Image-conditioned video with audio
Transforms a static image into a moving video with synchronized audio in a single model pass.
-
Preserves input composition
Maintains the subject, framing, and lighting of your reference image while adding natural motion.
-
DiT-based architecture
Built on Diffusion Transformer technology for detailed, temporally consistent video generation.
-
Flexible resolution
Supports 480p, 720p, and 1080p outputs to balance quality and cost.
-
Variable duration
Generate clips from 5 to 20 seconds.

How to Use
- Upload your image — the reference image that defines subject, composition, and lighting.
- Write your prompt — describe the motion, camera movement, and audio cues.
- Select resolution — 480p for iteration, 720p for balance, 1080p for final output.
- Set duration — 5-20 seconds based on your content needs.
- Run — submit and download the animated video with synchronized audio.

Best Use Cases
- Product Animation — Bring product photos to life with subtle motion and ambient audio.
- Portrait Animation — Animate headshots and portraits with natural movement.
- Social Media — Create engaging animated content from static images.
- Marketing — Transform key visuals into video ads with cohesive sound.
- Storytelling — Animate storyboard frames or concept art.
Pro Tips
- Audio is automatic — sound is generated based on visual motion and prompt context.
- Describe specific audio when needed (e.g., "rain", "jazz", "crowd noise").
- Use high-quality, sharp, well-exposed images for best results.
- Keep motion prompts simple — one clear action per prompt yields better results.
- Iterate at 480p to dial in motion, then render at higher resolution for final output.
- Use fixed seed when comparing prompt variations to isolate changes.
Notes
- Maximum video duration is 20 seconds.
- Width & height must be divisible by 32, frame count must be divisible by 8 + 1.
- The aspect ratio of output video is influenced by your input image.
- For longer content, generate multiple clips and edit together.
