Why would you do any conversion at all if you are to provide a "true and accurate copy" of all evidence to the defense? It's supposed to be an identical copy so the defense has the exact same evidence that the all-powerful state that has the power to put you in prison for the rest of your life does. Why wouldn't you just drag the file over to the dropbox folder shared with the defense, like every other piece of evidence that had been distributed? This isn't just a lawyer. This is an Assistant District Attorney, officially representing the government. They, all lawyers, are trained in handling evidence and know full well what their obligations and duties are. Even if it was somehow a "mistake," it's the type of mistake that trials are dismissed over, with prejudice, and rightly so, because it potentially biases every piece of evidence the prosecution handled. Besides, using handbrake doesn't completely change the filename, and we're not talking about appending "(1)", "(2)" or "(copy)" like an OS would do for files with the same filename in the same directory.
