Much has been said about the authenticity of the video Sarah Huckabee Sander's posted on her twitter account. Most recently Kellyanne Conway claimed the video was only sped up. Collecting the Motion History of each image and diffing the motion frame by frame I noticed a few frames where there is no motion in the Info Wars video. Seems like there is strong evidence that Kellyanne Conway maybe mistaken here. The Info Wars video is edited beyond speed changes.
