Track-v0

Track-v0

Track-v0 is a 1.3B causal WanTrack image-to-video checkpoint trained with sparse point trajectories.

Training recipe

• Initialization: WanTrack bidirectional stage-2 checkpoint 600
• Teacher Forcing: 3,000 steps
• Causal Distillation: 2,000 steps
• Self Forcing: 1,000 steps
• Published weights: Self Forcing checkpoint-1000 student_ema
• Attention: 3 latent frames per block, local attention 6, sink size 1, relativistic RoPE
• Training resolution: 832 x 480, 121 pixel frames / 31 latent frames

This repository contains the complete model bundle plus the full EMA transformer. The frozen TrackEncoder parameters are preserved from the initialization checkpoint; the remaining transformer parameters come from the final SF EMA.

Use this checkpoint with the FastVideo WanTrack causal model integration. See training_config.yaml for the exact model and pipeline configuration and export_receipt.json for provenance hashes.
