Please provide any additional information below.
Issue if you are rendering a layer with 3D motion blur and a layer without 3D motion blur, but with motion vectors. Keyframe location needs to be start of frame for motion vector layer to match motion blurred render.
You can get around this with separate batch renders and changing the setting manually in between.
Or bring back motion offset? -not in legacy options with shutter open/close
