For people thinking it detected the decoy text. It did not. It was the text I entered myself. Here are the thinking steps:

  Inspected video metadata, extracted frames, and analyzed content
  Detected and analyzed periodicity in stereogram image data
  Blurred, downsampled, and analyzed image frames
  Computed frame pixel shifts and cross-correlation
  Checked OpenCV installation, optimized and analyzed optical flow processing
  Analyzed motion for text
  Estimated vertical displacement and processed image flow
  Refined text extraction
  Processed optical flow and analyzed image
