An AI can replace what a world leader said in his video-taped speech. This will end well. Not
Researchers have crafted algorithms that can blend an audio recording of someone talking with a video of them saying something else entirely – and create a new convincing lip-synched video with the replacement sound. In other words, the resulting video carries the injected audio, rather than its original sound, and the frames …

Re: video-taped?
Not many do, it has turned from a physical act into a recognised expression.
If you want to go down the pedant route, you might want to think about what digital video recorders do with their captured video, they effectively save the video data to their storage medium.
But having a title with "said in his video data saved speech" doesn't seem right, so "video-taped" is still appropriate.

Re: video-taped?
Yeah. Like you "wind the window down" in your car, whilst listening to an internet "Radio station" and "dialing" a friend on your cellphone...who tells you they've just booked a cruise on an ocean liner that's going to "sail" round the world. Then, after you've "hung up" on them, you decide to read some emails that have been "carbon copied" to you.

The AI said it had a better idea
Instead of training an AI how to use audio to fix the replayed video, just train an AI to use the original video to fix the replayed video. It's a much more direct route and it can be extended to improving video compression in general. Video compression attempts to describe changes that are happening as best as possible and everything else becomes a flood of image data. Right now those descriptions are not much better than saying what is moving, what looks like something else, and which scene cut is on.

Render the mouth perfectly
Or use a low quality video or one taken from sideways to dub in the fake speech, and you don't need to bother with such perfect rendering. I fully expect that if for example someone like Flynn produced a recording of Trump approving collusion with the Russians (i.e. part of a plea deal to save his skin) Trump would deny it and claimed it is faked, and his supporters would believe it.
Even if it was perfect 4K video, someone at Breitbart would link to this research, and all the Trump bots would fall into line. Doesn't matter if the technology isn't ready yet, the existence of research merely discussing the possibility means that video evidence will no longer be acceptable to the suitably brainwashed.

Re: Render the mouth perfectly

The suitably brainwashed never required plausible research in the first place. Just think about all the flat-earthers, AGW-deniers, Holocaust-deniers, anti-vaxxers and Creationists already out there.
(I'm now going to sit here and wait for one of them to turn up and say they have tons of evidence in their favour.)

Doesn't do it for me. The mouth looks good but Obama has a very pronounced body language when speaking which is not changed from the original. So suddenly his head an shoulder movement doesn't match the emphasis of his speech. It's good I'll give em that. And somre people might be convinced but I vmcan tell something is off.

Ditto. In some places, I felt that if I was watching a movie, I might be wondering if the original audio had been dubbed with something similar, but not quite the same.
Also, look again at 1:23 in the video, when the person Obama is talking to says "Okay" - the Fauxbama attempts to mouth the word.

I BIT clonton Is AREADY DOIN thug To TRUMPI
Sometimes TRUMO DOESNT LOOK like hes Sayin whAT hes Sayin SO INBET FER INSTANCE clintun IS PUTTING words INTO HIS MOUTH. AND probably MOAR BESIDES. THats why the GRATE PRESIDON't TRIMP uses TWOOATER to get His pIlocys Across to the Citizens Of the US AND THE WORLD (except FRANCE they have UNIINS AROUND THEIR NEXKS). In that way HE DONT GET HICKED. WITH melooonier (1nd lady) BYNHIS SIDE. Nkkid with gun. (Me not HER. I AM INNTHE BATH WITH a lug Pig. pug. SOAP).

Talking head?
One option not mentioned is a person recording and encoding a high resolution head, then supplying it before hand to participants in a video conference.
The bandwidth required to maintain a high resolution image in the conference would be greatly reduced.
A very personalised avatar.
It would, of course, require some form of cryptography to guarantee that you were talking to the originator and owner of the data.

Re: How does this overcome a properly crytographically signed video with audio?
My thoughts exactly. Digital watermarks are your friend here. Besides, AI may also be used to find the original, untampered footage, using content-based video retrieval, if said original footage is publicly available
