To anybody oriented to video editing as Mac is, that chop edit in its raw form was the equivalent of an earthquake, massively obvious. And of course there would have been a shift seen on the guy, nobody holds perfectly still. It's one of those things they figured they could get away with given their laymen audience, not so vid pros. Not even close.
You'd never get away with an audio edit-only either. The lip flap wouldn't match. Pros can spot that a mile away.
As someone who once did non-linear editing for a living, installs and maintains NLEs, and is still around it daily, I'm afraid I have to disagree.
First, you can edit all the jump cuts you want into the footage, because they can be separated by B-roll (or a cut to a shot of the interviewer, although not in this case because the interview was not done by talent but by a producer, and that in itself is high-handed plot manipulation because virtually any interview of any weight is done by talent, so they cooked the books on the procedural part here just to create the opportunity to put the finger on Jerry--in real TV that does not happen).
And SPOILER ALERT, read this later if you have not seen "Red Team III".
Second, the interview was not an edited interview, it was a series of individual sound bites, meant to be dropped into the show one by one as the anchor referred to them, so there really is no editing for air per se, only editing for the production convenience of how these sound bites are rolled in to the broadcast. What Jerry did is edit the original footage itself out of context, specifically to hide the context, not from the viewers, but from the team. That is very different than editing for air, and he was able to do this without a jump-cut on air because the clip was an individual sound bite and could start or stop wherever.
Jerry also blurred the TV in the shot in editing, and while that was supposed to be because these things are blurred normally to protect airing rights, Jerry did that to fool the team and hopefully hide his underhandedness from them. What doesn't pass the smell test is that he was clever enough to perform the out of context edit on the clip sent to air by editing it out first in the original raw footage, yet was not clever enough to put the blur on the original raw footage, which made that a clue just waiting to be discovered. Blatant plot manipulation. It would actually have been clearer to the viewer (of The Newsroom, not of the fictional news broadcast) if "McMac" had been able to find the original footage with the original quote in its clear original context, and not missing the "If we used sarin...", precursor. That might have eliminated a lot of WTFs in HBO homes.
Maybe it is my closeness to this industry, but I could see this coming all the way down Broadway, especially because we all knew Genoa was going to blow up in their faces ahead of time just from the HBO promotion. The whole thing about the General loving B-Ball and him having the TV on and Jerry wanting the medals in the background so he had to have the live TV feed there seemed like a clumsy setup from the beginning. I just knew this was going to be the key to catching Jerry, but I had to wait through 3 more eps and an inane discussion about shot clocks before the other shoe finally dropped, and "McMac" finally allowed this elephant in the room to dawn on her.
They had 4 pieces of "evidence", 3 independent confirmations, another from Will, and 3 high-level long Red Team meetings agonizing over this yet the only one who ever saw the footage of Stomtonavitch was Jerry? A producer from out of town? Nobody from the core team went and looked at it? Cut me a break. That alone fits the definition of "institutional failure".
