What problem does it solve?

LVSA troubleshooting identifies and remedies silent failure modes where the LongVideo Sparse Attention path does not engage, resulting in missing speedups, unexpected fallbacks, OOMs, or degraded output quality.

Core Features & Use Cases

  • Guided diagnostics for common LVSA failures (geometry detection, backend engagement, and keyframe sparsity settings).
  • Configuration checks with recommended environment variables to ensure LVSA activates across Wan, HunyuanVideo, CogVideoX deployments.
  • Practical playbooks for verifying logs, outputs, and fallback behavior, plus remediation steps for VAE memory pressure via latent outputs.

Quick Start

Run the LVSA troubleshooting workflow on the current run to collect log lines and apply the recommended fixes.
