LTX-2 VBVR LoRA - Video Reasoning

LoRA fine-tuned weights for LTX-2.3 22B on the VBVR (A Very Big Video Reasoning Suite) dataset.

Training Data

To ensure training quality, we preprocessed the full 1,000,000 videos from the official dataset and randomly sample during training to maintain data diversity. We adopt the official parameters with batch_size=16 and rank=32 to prevent catastrophic forgetting caused by excessively large rank.

The VBVR dataset contains 100 reasoning task categories, with ~10,000 variants per task, totaling ~1M videos. Main task types include:

• Object Trajectory: Objects moving to target positions
• Physical Reasoning: Rolling , collisions, gravity
• Causal Relationships: Conditional triggers, chain reactions
• Spatial Relationships: Relative positions, path planning
