What changedForkLog reports a further finding from the University of Hong Kong study: most of the video-generation models scored worse when researchers added a reference image to a text prompt.
For Wan 2.6, the score fell from 3.41 to 2.75, according to ForkLog. That gives a concrete example of how adding an image can change a model’s result in the study.
The finding adds a useful wrinkle to comparisons based on a single overall ranking: performance may shift with the prompt setup, not just the model. How much should image-prompt results count when judging video models?
