Troubleshooting Wan2.2 I2V: Why is the Last-Frame Input Being Ignored?
New_Geech · reddit · 2026-07-30
A developer encountered a technical roadblock while using ComfyUI for Wan2.2 Image-to-Video (I2V) generation: the model completely ignores the last-frame input, causing the video to go off on a tangent.
- Setup: To accommodate low VRAM, the user is running a Q4 GGUF quantized version of the Dasiwa model, with a 0.52 MP resolution preset, 'simple' scheduler, and SageAttention enabled.
- Troubleshooting: The user has verified they aren't accidentally using a Text-to-Video (T2V) model and checked frame counts, but the issue persists. They are seeking community insights to resolve the boundary constraint failure.
