abstract: >
  NExT-CF is a benchmark of 570 counterfactually edited videos derived from NExT-QA,
  used to probe whether Video Question Answering models rely on visual evidence
  or language priors. Each video has a target entity removed via SAM3 segmentation
  and DiffuEraser diffusion inpainting, with the corresponding QA pairs carried
  over from NExT-QA.
