LTX-2.3 Text-to-Video LoRA
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 generates synchronized video and audio from text prompts in a single pass, bringing together the core building blocks of modern video generation with open weights and practical execution.
Why Choose This?
-
Improved quality Enhanced audio and visual quality compared to LTX-2, with better prompt adherence and more coherent outputs.
-
Synchronized audio-video Generates video with matching audio in a single model pass, no separate audio production needed.
-
DiT-based architecture Built on Diffusion Transformer technology for high-fidelity, 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.
Parameters
| Parameter | Required | Description |
|---|---|---|
| loras | No | List of LoRA models to apply (max 3, each with path and scale) |
| prompt | Yes | Text description of the video scene, motion, and audio |
| resolution | No | Output resolution: 480p, 720p (default), or 1080p |
| duration | No | Video length in seconds (5-20) |
| seed | No | Random seed for reproducibility (-1 for random) |
Resolution Options
| Resolution | Best For |
|---|---|
| 480p | Fast previews, iteration, lowest cost |
| 720p | Balanced quality and cost (default) |
| 1080p | Final delivery, maximum detail |
How to Use
- Write your prompt — describe the scene, 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 video with synchronized audio.
Pricing
| Resolution | 5s | 10s | 15s | 20s |
|---|---|---|---|---|
| 480p | $0.15 | $0.30 | $0.45 | $0.60 |
| 720p | $0.20 | $0.40 | $0.60 | $0.80 |
| 1080p | $0.25 | $0.50 | $0.75 | $1.00 |
Best Use Cases
- Content Creation — Generate video content with synchronized audio from text descriptions.
- Social Media — Create engaging video posts with cohesive sound.
- Marketing — Produce video ads with matching audio from creative briefs.
- Storytelling — Bring written narratives to life with video and audio.
- Prototyping — Quickly visualize concepts with audio-visual output.
Pro Tips
- Audio is automatic — sound is generated based on visual content and prompt context.
- Describe specific audio when needed (e.g., "rain", "jazz", "crowd noise").
- Keep prompts clear and specific for better prompt adherence.
- Iterate at 480p to dial in content, 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.
- For longer content, generate multiple clips and edit together.
- Model is not intended to provide factual information.
