Learn how to generate AI videos for free using ComfyUI + Wan 2.2 — the most powerful open-source AI video engine available today. This step-by-step tutorial covers text-to-video, image-to-video, prompt crafting, model comparison (5B vs 14B), and GGUF quantization for low-VRAM cards. Everything runs locally on your GPU with zero subscriptions.

What you'll learn in this video:

- Why local video generation beats paid services — Runway ($15/mo), Pika ($8/mo), and Sora all charge per-use or monthly. ComfyUI + Wan 2.2 is free forever, fully open source (Apache 2.0), and runs on your own GPU with no credits, no watermarks, and no limits.
- The model landscape — Wan 2.2 vs LTX Video vs Hunyuan Video vs CogVideoX. Wan 2.2 wins with Mixture of Experts architecture, cinematic quality, and a 5B variant that fits on 8 GB VRAM.
- Prerequisites — ComfyUI installed and running, NVIDIA GPU (8 GB+ VRAM for 5B, 24 GB+ for 14B), 16 GB system RAM, ~20 GB free disk space for models. Updated NVIDIA drivers required.
- Download the models — Three files from the Comfy-Org repackaged repo on Hugging Face: diffusion model (wan2.2 TI2V 5B FP16, ~10 GB) → models/diffusion_models/, VAE (wan2.2 VAE, ~1.3 GB) → models/vae/, text encoder (UMT5 XXL FP8, ~6.3 GB) → models/text_encoders/. Total ~16.9 GB.
- Your first text-to-video — Load the Wan 2.2 5B Video Generation template. Set resolution to 832x480, 81 frames (~3 seconds at 24 fps). Type a cinematic prompt and hit Ctrl+Enter.
- Prompt crafting — Write like a director: subject + action + camera movement (dolly, tracking, orbital, crane) + lighting (golden hour, neon) + mood (cinematic, anamorphic). Aim for 80–120 words. Negative prompt recommended.
- Image-to-video — Press Ctrl+B to enable Load Image. Upload any image as the first frame and generate motion from your prompt. Perfect for animating AI art, product reveals, or photos.
- The 14B quality upgrade — Dual diffusion models (high-noise + low-noise) via MoE architecture. ~33 GB total. Finer details, more natural motion, better prompt adherence.
- GGUF quantized models — Run 14B quality on 8 GB VRAM. Install the ComfyUI GGUF custom node from Manager. Slight quality trade-off for dramatically lower memory usage.
- Pro tips — Start at 480p for fast iteration, bump to 720p for final render. Lock the seed for reproducibility. 80–120 word prompts work best.
