<h2 id="wan-2.2-i2v-workflow-(optimized-for-12gb-gpus)">WAN 2.2 – I2V Workflow (Optimized for 12GB GPUs)</h2>A fast, clean, and VRAM-efficient Image-to-Video workflow built around WAN 2.2. Fast render times on mid-range GPUs. I tried to keep this simple and easy to use, while maintaining good results. Utilizing well known nodes, and minimizing node bloat. The workflow also has comments everywhere and clear flow.Ver 1.0 - Base workflow, can do 5 second clips in one iteration. (very fast for 12gb)Ver 1.1 - More stability, can run 100 times consecutively in 8hrsVer 1.2 - Renders 20 second videos. Cleanup of wires.Ver 1.3 - MMAudio added.Ver 1.4 - 2x Upscaling, color correction, &amp; sharpening in between passes for quality consistency.<h3></h3><ul><li>WAN 2.2 Model Use either lightweight GGUF models or full <code>.safetensors</code> checkpoints.
