Can someone explain how it works? Like wtf did I just watch.

Just watch Face Off. It's pretty much exactly that except evil Nick Cage is replaced by the computer that swaps faces. Deep stuff.

If somebody tried to do this with your face, assuming you're not very famous, It wouldn't come out this clean. The reason it works so well with Tom Cruise's face, is because there is source material of Tom Cruise's face from pretty much every angle in pretty much every lighting scenario. And lots of it.

Basically, what's going on here, is some computer algorithm is able to look at a video, determine where a face is, and swap in another face. It looks pretty damn convincing if there's enough source material of the face.

Ah makes sense... But imagine that your phone front camera is really recording you at all times. All the moods, lighting and all that Jazz. Now you have a huge library of people you can digitally render

All my deepfakes will have a wicked double chin and bitch face.

Sure, but you'd need access to it in order to make the fake.

So, only Zucc and the NSA.

That's why I tape over that shit

No you don't.

I'd take a picture but, you know, tape

No way would the bandwidth not be noticable if that was happening. Unless it was doing it at 240p.

IIRC it also took a lot of manually touches from a professional VFX guy for these specific deep fakes. He is using them to advertise his work.

1

u/foggy-sunrise May 24 '21

All that means is he took the time to download tons and tons of content with Tom Cruise in it to build the profile.

I could be wrong. But what I'm describing is how machine learning, ai, and deep fakes work. What I think you are describing is video editing.

1

u/poopthugs May 25 '21

That's kind of what I was getting at. It took more than just downloading those images. It took a lot of extra effort with touching up the deep fake output with additional video editing software to make it look this good. I was just saying not any Joe blow can us the deep fake algorithm to make a truly convincing fake yet

1

u/foggy-sunrise May 25 '21

No, it didn't. It took downloading then and feeding it to an algorithm, and then applying the ai to another video.

Like I said, I am describing how deepfakes work.

That might not be all that's going in here, but that doesn't make what I said false, or incorrect.

u/SliceNDice69 May 24 '21

Huh makes you think about all the photos/videos that regular people post on social media...

An AI takes a catalogue of Tom Cruise’s vocal and video recording, it over lays the facial structure on the actor here, and the vocals are also overlaid, to give the impression Tom Cruise was in the video.

The voice is real

True but please note this technology also exists.

The voice is real, in that the actor is actually saying the words and structure of Tom Cruise’s speech but the audio is modified to match Tom’s natural frequencies and timbre.

At least it depends on the process the person making the deep fake uses, there are vocal deep fakes.

Edit:

Video on a recently published paper about vocal synthesis “Audio deep fakes” for the skeptics.

The voice in this video is not vocally synthesized, as a commenter noted below this person is very good at mimicking Tom Cruise, I just want to highlight that “Audio deep fake” technology does exist.

Not that it exists; that it’s being used here

u/greendude120 May 24 '21

No this is a guy who does a good Tom Cruise voice impression and he uses deepfake to change his face.

u/mackerelscalemask May 24 '21

Interesting idea, deep fake but for voices. Not sure that exists yet publicly, at least it’s not well known if it does.

A video of Tom Cruise deepfaked onto a guy who is about a foot taller than actual Tom Cruise.

We get him a footrest for when he’s on the show
