Tips & Tricks for Best Results​

• Low VRAM Settings:
  Use --medvram or --lowvram flags when launching if you're facing memory errors.
• Frame Selection:
  Pick clearly visible start and end frames with similar lighting and perspective.
• Inpaint Mask Precision:
  Use black-and-white masks for better results—black hides, white reveals.
• Use Queue Limit:
  Set queue to 1–2 to avoid overloads on lower-end GPUs.

Common Issues & Fixes​

• Missing Nodes?
  Make sure you’ve installed all custom nodes using ComfyUI-Manager. Restart ComfyUI after installing.
• UI Not Loading or Crashing?
  Double-check Python version (use 3.10+), reinstall dependencies, or use a fresh ComfyUI install.
• Output Looks Glitchy?
  Make sure your input frames are clean and consistent. Re-run with different frame intervals if needed.
