Earlier quoted context omitted.
Of course you don't have to be an engineer to use it, but if he's really claiming to know nothing about encoding, that's quite the contradiction.
I don't think that's necessarily the case. In fact, I can very easily see a lawyer clicking the "fast convert" (or similar) checkbox, not realizing that doing so compromises the encoding quality. For all I know, that setting is the default.
Furthermore, I think the prosecution has been terrible, and at times, downright malicious (trying to get a mistrial after their start witness flopped, etc).
HOWEVER I really do agree with this take. I'm fairly computer literate (sysadmin for a microscopy facility, daily drive Linux, couple years of web development under my belt) and recently spent a non-insignificant amount of time trying to create a video from a bunch of .tif files and embed them into a PowerPoint. It was not simple or easy. Working with video is always an annoying, expensive, black box. Sometimes I'd do things, and it would just come out a blurry mess. Or balloon in file size for no obvious reason.
