Research direction

Start at diffsynth/pipelines/wan_video.py line 1088 and inspect how the Wan S2V pipeline accesses wantodance_enable_global. Exercise the Wan S2V path and other Wan models after the change; done means S2V no longer fails when that attribute is absent and existing models continue to work.

Written by the indexing model from the issue text.

Description

~/repos/DiffSynth-Studio/diffsynth/pipelines/wan_video.py at line 1088:

OLD (breaks Wan-S2V)

if pipe.dit.wantodance_enable_global:

NEW (safe for all Wan models)

if getattr(pipe.dit, 'wantodance_enable_global', False):

This fixed the issue for me, looks like Wan S2V does not have the wanttodance_enable_global attribute
