Aside from the confusion about logarithms, where I presume he meant algorithms, and the false claim about 3D, the defence was making a claim about artificial intelligence being used to upscale the footage. Which is inaccurate, and a specific claim being made that's unsupported by any evidence.
Funny enough, the same sort of question arose with regard to a crime scene image that was enlarged by the state's forensic lab, but a simple explanation of the mechanism used was deemed sufficient.
