How to run local T2V/I2V/V2V video AI on an RTX 5070 with only 12GB VRAM

A Reddit user is asking how to maximize local AI video generation on an RTX 5070 (12GB VRAM, 32GB DDR5).
- Goals: T2V and I2V clips with subject consistency, plus V2V restyling of real footage without background bleeding or face distortion
- Questions: is ComfyUI with custom nodes still the best UI; which models (Wan2.1, CogVideoX, HunyuanVideo, LTX-Video, AnimateDiff) work within 12GB and whether GGUF quantized versions are viable
- Seeking node recommendations (ControlNet, IP-Adapter, LivePortrait, FaceSwap) for coherence in V2V workflows
