Performance Tips

Optimization Strategies

Choose the Right Model Variant
- Use Q4_K_S quantized models for 12-16GB VRAM GPUs
- Use FP16 models only with 24GB+ VRAM for maximum quality
Enable Memory Optimizations

python
1pipe.enable_model_cpu_offload() # Offload inactive components to CPU 2pipe.enable_vae_slicing() # Process VAE in slices 3pipe.enable_vae_tiling() # Tile-based VAE processing
Adjust Inference Parameters
- Lower resolution (480P) reduces VRAM by ~40%
- Fewer frames (16 vs 32) reduces memory proportionally
- Fewer inference steps (30-40) speeds up generation with minimal quality loss
Batch Processing
- Process multiple images sequentially rather than in parallel
- Clear CUDA cache between generations: torch.cuda.empty_cache()
Multi-GPU Strategy
- Use device_map="balanced" for automatic distribution
- Enable FSDP (Fully Sharded Data Parallel) for large batches

Quality vs Speed Trade-offs

Configuration	VRAM	Speed	Quality	Best For
FP16 + 50 steps + 720P	20GB	1x	100%	Final production
Q4_K_S + 50 steps + 720P	14GB	1.5x	95%	High-quality preview
Q4_K_S + 30 steps + 480P	10GB	3x	85%	Rapid iteration
Q4_K_S + 20 steps + 480P	8GB	4x	75%	Low-VRAM testing

Troubleshooting

Out of Memory Errors:

Switch to Q4_K_S quantized model
Enable all memory optimizations
Reduce resolution to 480P
Decrease frame count to 16
Lower inference steps to 30

Slow Generation:

Use quantized models (Q4_K_S)
Enable torch.compile() for faster inference (PyTorch 2.0+)
Reduce inference steps to 30-40
Consider multi-GPU setup

Quality Issues:

Use FP16 model if VRAM allows
Increase inference steps to 50-70
Ensure input image is high quality (512x512 minimum)
Use descriptive text prompts for better guidance
