Voice sounds even more unrealistic than the video (source: I'm Ukrainian). No one in Ukraine would believe the audio part of this fake, even if video was perfect. This is a pathetic attempt. Also, the script (the text that is being read) is written as if the target audience are Russian, not Ukrainian people (because it's based on propaganda narratives that people outside of Russia are not familiar with). This is such…

I assume the good deepfakers are using social media datasets to trick unsuspecting grandparents into giving up money, not meddling in geopolitics.

For him the deep fakes will be used to make considerate and respectful comments, while the real videos will be the outrageous ones :-)

That might be the best way to make him do something. When he realizes that people think the fake video makes sense, he'll claim the video was real out of spite and start defending a reasonable position.

Is this true? I don't see much evidence that the technology is progressing in a direction where models will require less training data, if anything the trend seems to be towards models with higher and higher parameter counts.

It's somewhat true. Better models are coming out which are already pretrained on a significant amount of data, so the model already learned a lot about what is common to all example of video generation (keeping the edges aligned coherently at every frame, keeping texture and lighting coherent etc.) and will not need to re-learn that for every target. Since initially, deepfake models were trained from scratch for ever…

At least in my experience - audio is much harder to convincingly fake than video. If you have heard the real person speaking, they have very specific and distinguishable patterns of speech.

You can fake it reasonably, but you need to have a very large collection of audio clips to do so, and if you do a bad job it literally jumps out at the viewer.

Video might be off, but it requires close attention and large screens to notice - much easier to miss if you're viewing on a phone.

I've seen a deep fake with Putin "surrendering" on 28th of February: https://youtu.be/ZbudZw1LlHg I guess the video itself was made even earlier than that. The video is not excellent, but the audio is pretty spot on, if you ask me. Edit: re-worded the first sentence.

-258 views -nonsensical title -no comments -all videos on account are unlisted -you just found it Hmmm. How did you “find” this?

@osynavets , not clear what you meant by

"Volodymyr Zelensky asking to retreat and surrender their weapons"

did it mean:

Volodymyr Zelensky asking invaders, Russia, to retreat and surrender their weapons

?

I always find it interesting to watch the trickle down of news I find here on HN. I live in a very, very, very conservative part of the US. It always goes the same; see fake thing called out for being fake on HN. One week later, hear rumblings related to the fake thing in my community. One week after that, hear people openly talking about how that fake thing is true, but Google/MSM don't want you to hear about it. Su…

Whenever I stumble into a political conversation with someone who prefers to live in an alternate news reality, I find it effective to not argue back at them, but rather out-flank them: inform them that not only are they correct, but also I read that insert-like-minded-improvised-obviously-ridiculous-nonsense-here and say it with all sincerity ... and then let them respond with "Well ... I'm not sure about that ..."…

I like this idea in theory, but suspect I'd be depressed how often people actually agreed with my attempt to outcrazy them in practice.

Give it a couple of years and the tech will spread A LOT.

The tech is already good enough for anyone to make a convincing deepfake, I think, and especially state actors - or people with deep enough wallets - can perfect it. I mean some of the memes of e.g. Obama saying something he never did are convincing enough.

The Tom Cruise ones going around a while ago were indistinguishable from reality for me. Granted I'm not intimately familiar with Tom Cruise, just watched some of his movies, but I could see believing them if I didn't know they're deep fake.

Living in rural America, where it is safe, and folks are polite and friendly and happy to leave you alone (if you're white), I have to say that doesn't mean people don't believe batsht crazy things. Because lots of them do. Or at least say they do, 'cause there is a big step between saying you believe something and actually acting like you do.

Believing batshit crazy things isn't unique to rural areas. In fact, I'd say it's more common in cities simply because there are more people there. I know a woman who lives in Chicago who doesn't believe in dinosaurs. It's not a religious thing, it's just that dinosaurs don't fit into her mindset somehow. I dated a woman in New York (native New Yorker) whose entire family believed that the moon landings were fake. I…

Oh I agree.
