Research direction

Reproduce the inference script and inspect diffsynth/models/wan_video_vace.py at lines 60-61, then trace the tensor inputs from diffsynth/pipelines/wan_video_new.py line 1161. Compare the shapes produced by the training and inference inputs; done means the reported negative-dimension error is understood and the VACE inference run completes successfully.
