The 2:26 glitch to me looks like a mpeg transmission error which caused the decoder to shift the chroma to the right.
Not to get too technical, basically video transmission does not work with RGB pixels (red/green/blue intensities) but with luminance (luma) and chrominance (chroma). Luminance being basically a black and white picture of light intensities, and chrominance being a picture just of colour information. When the glitch occurs, the entire colour information shifts to the right and you can see a blob of brown colour to the right of the cup. There is also a shadow to the right of the fold in the backdrop. The video stabilizes after having a further glitch manifesting as scattered blocks.
See here for example of what is luma/chroma: http://images.digitalmedianet.com/2007/Week_9/pu0br08v/story/photo_luma_chroma.jpg
What you saw in the video was the colour being shifted momentarily.
