Image Processing (PyTorch GPU tensor operations):
- ZoomSequenceNode: Add device handling for GPU-accelerated F.interpolate
- CameraShakeNode: Ensure tensors stay on GPU device
- CameraMoveNode: Add device handling for GPU acceleration
- Expected gain: 4-10x speedup for large batches
Video Encoding (NVENC support):
- VideoLoopExtenderNode: Add use_gpu parameter for HEVC_NVENC encoding
- Falls back to libx264 if NVIDIA GPU unavailable
- Expected gain: 5-10x speedup for video encoding
Note: ComfySimpleVideoCombiner and ColorAdjustmentVideoNode already had
GPU support implemented, so no changes were needed.
Safe, backward-compatible changes with runtime GPU detection and fallback.
