I only did 12 of them before exiting but got 100% of them. I watched them on my phone without turning it landscape to simulate how I'd normally watch a brief news clip like this.

They're still not particularly convincing, especially the audio ones sound very fake.

But I think these sorts of tests are flawed. The fact that it's a test primes you to look for these details in a way you might not if these clips were shared on Twitter/Reddit/etc. The deepfakes are still pretty obviously fake, so I don't think I'd fall for one "in the wild". But I also see this style of test used for things like "can you hear the difference between these 2 audio compression formats" or "does this virtual guitar amp sound just like the real thing", and that's just not how you consume real media. For example I'd probably never know Meshuggah switched to entirely digital guitar amps years ago if it weren't for them saying it in interviews.

When deepfakes one day do get as close to the real thing as digital guitar amps have gotten to real amps, I doubt I'd notice a random r/worldnews post is faked, even if I could still reliably pass an A/B test.
