"Compare the test video (the first 24 frames) to the reference frame (the last frame) and decide if the video shows obvious visual-quality (VQ) defects relative to the reference.\nConsider only: blur (defocus/motion), compression artifacts (blocking/ringing/mosquito), noise/grain, banding, flicker, rolling-shutter, aliasing/moire, over-smoothing.\nReturn ONLY this JSON (no timestamps):\n{\n \"has_obvious_defect\": Yes | No,\n \"dominant_issue\": \"none|defocus_blur|motion_blur|blocking|ringing|mosquito_noise|grain_noise|banding|flicker|rolling_shutter|aliasing|moire|over_smoothing\",\n \"evidence\": [\"short visual cues vs reference, e.g., 'softer edges than reference', 'block edges visible around text'\"],\n}\nRules:\n- Compare against the reference frame\u2019s look (sharpness, texture, edges, tones).\n- Be conservative; if unsure, choose false and note 'uncertain' in evidence."
