Integrate EMA-VFI alongside existing BIM-VFI with three new ComfyUI nodes: Load EMA-VFI Model, EMA-VFI Interpolate, and EMA-VFI Segment Interpolate. Architecture files vendored from MCG-NJU/EMA-VFI with device-awareness fixes (removed hardcoded .cuda() calls), warp cache management, and relative imports. InputPadder extended to support EMA-VFI's replicate center-symmetric padding. Auto-installs timm dependency on first load. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
