Features

LTX-2 19B IC-LoRA Trainer

LTX-2 19B IC-LoRA Trainer is a high-performance custom model training service for the LTX-2 19B video generation model. It allows you to train lightweight LoRA (Low-Rank Adaptation) adapters for personalized styles, characters, and concepts — bringing your custom visuals into AI-generated videos with synchronized audio.

Why Choose This?

• Video LoRA training Train custom adapters specifically optimized for LTX-2’s 19B DiT video architecture.

• Character consistency Create LoRAs that maintain character identity across generated video clips.

• Style personalization Capture specific artistic styles, brand aesthetics, or visual themes for video content.

• Seamless integration Trained LoRAs work directly with LTX-2 Text-to-Video LoRA and Image-to-Video LoRA models.

Training Process

1. Data Upload Prepare and upload a ZIP file containing your training images. Include 10-20 high-quality, diverse images for best results.

2. Configure Trigger Word Set a unique trigger word (e.g., “p3r5on”) that will activate your trained style or character in prompts.

3. Adjust Training Parameters

   • steps — Total training iterations (default: 500)
   • learning_rate — Training speed (default: 0.0002)
   • lora_rank — Adapter capacity (default: 32)

4. LoRA Training The system runs a tailored LoRA optimization loop:

   • Freezes the base model weights
   • Trains only the low-rank adapter layers
   • Applies LTX-2 optimized settings for video generation

5. Model Export After training completes, you receive a LoRA adapter file (.safetensors) compatible with:

   • LTX-2 19B Text-to-Video LoRA
   • LTX-2 19B Image-to-Video LoRA

Parameters

Pricing

Billing Rules

• Base price: $0.75 per 100 steps
• Total cost = $0.75 × (steps / 100)
• Billed proportionally to the total number of steps in your job

Best Use Cases

• Character LoRAs — Train on character images to maintain identity across video generations.
• Brand Styles — Create custom visual styles for consistent marketing video content.
• Art Styles — Capture specific artistic aesthetics for creative video projects.
• Product Visualization — Train on product photos for consistent video presentations.

Pro Tips

• Use 10-20 high-quality, diverse images of your subject for best results.
• Choose a unique trigger word that won’t conflict with common words.
• Higher lora_rank (32-64) captures more detail but increases training time and file size.
• Lower learning_rate is more stable but requires more steps.
• Start with default settings, then adjust if needed.

Notes

• Higher parameter values (steps, lora_rank) will increase training time.
• Training time scales with the number of images and total steps configured.
• For faster iterations, start with lower settings and increase gradually.
