Which one of you was this?

[Alan in Tempe]

Brah -The best thing about AI is that it tends to be pretty good at knowing its own handiwork. Out of boredom whist waiting for some other stuff to finish, I let an agent loose on this for you. There is NOTHING in this video that it could find, after around 10 mins of playing around with OpenCV that would indicate a kind of image manipulation beyond compression and an overlaid soundtrack. You know sometimes a video is just.... ...a video.

Very true, all, except how good AI is at recognizing other AI generated videos. AI is only somewhat reliable in recognizing AI content generated by older AI. The AI tools readily available today can fool most AI experts, AI and human. However, that is referring to high quality AI works, and most consumers use AI tools that don't work at that level. Yes, this may not be AI. No, I have seen no good argument against it being AI, and a number of elements that tell me it is.

In case anyone cares, I am an AI engineer with graduate degree in AI from Purdue, and 35 years engineering experience, mostly in AI, including LLM development. I have published papers in expert systems, and two AI related patents, one in legal reasoning, and one combining expert systems with neural networks. None of my work experience is in AI video generation, but I understand the technology very well. To be honest, however, my credentials and experience in AI is of little more value on this video than is the value of a local resident who saw the boulder. It is my understanding of physics, boulders, and asphalt that tell me it is a fake. I am not certain it is.

Don't you get tired of being wrong?

Do you think I am wrong about the size estimate of the boulder, or the expected density the boulder, or my math is estimating the weight? Was there anything else in that post I could have been wrong about? Or, is your question on the same level as "Have you quit beating your wife?" as a hollow accusation only?

Any AI good enough to produce this without ANY AI creation tells, would also be good enough to do the basic physics dude.

That is completely wrong on two counts. It would not take a very sophisticated AI tool to make this, and even the best of these tools have "hallucination" problems, which require humans to drive iterations to remove.

Thank you for the excellent demonstration of how easy it is to generate these fake videos. And, thanks for leaving in so many obvious clues that this is AI generated.

Starting by estimating it as a cube was a choice.

Ignoring the watermark, physics etc - @Dark-Fx's video shows inconsistency in the background etc:

• Power lines and poles do not maintain clean spatial relationships.
• The landscaping has the “plausible texture” look rather than stable, inspectable detail.

There is none of this in the original clip - It would take a really sophisticated tool to make this. Based on your post above I hope you think about going back to school - I was doing AI at Edinburgh University in 2000 so I can't match your 35 years of experience and it was an undergrad degree, but think I've picked up a thing or two along the way...

This thread demonstrates a AI threat not discussed often enough. AI or not, we have an AI expert telling us that this is AI.

Have you considered that it could indeed be a "landscaping fake rock"? Which would weigh a fraction of a "real" boulder, but not be AI? Sometimes used to create the illusion of a barrier.

Its kinda funny - the Facebook comments in the original video note the number of times this has happened - and comment that perhaps they should buy a real rock...

Unless he saw the Rivian hit the boulder, or has access to the original mall video of the event and saw the raw video, then there is no reason that the local person who is a Facebook friend of the mall would have any superior info on whether the video was AI generated or not. This would be an easy video to have an AI tool generate, and there are a number of issues that I have explained which strongly suggest it is AI enhanced.

It was posted on the Mall's page. Someone who's a friend of the mall can't post things on there; it's a business page, only the admins can post. Keep on reaching, it's working out well.

Ya don't say?

Amazing that he wades into this (unasked for) and keeps asserting he is right and cannot fathom he is wrong with someone with local info and others who dug and show it was a fake rock (not 200lb per sqft). Amazed he put so much effort into something so inconsequential and was meant to be a joke type thread.

Some people just have to be right. I guess AI isn't the only thing that hallucinates in this thread.

No, I did not think of that. That could explain the video as not faked. There are two reasons I suspect it is not a fake boulder. First, the Rivian appeared to hit something very solid which does not seem to have been damaged by the hit. Second, a fake boulder as light as this appeared as it bounced and rolled should be easy enough to move back in place with a hand truck, easier than rounding up some traffic cones to warn people of the danger left in the middle of the parking lot. Nonetheless, that is the most plausible explanation I have heard so far.

 

[VegasWeezy]

Stanfield says it is not based on AI because he has personally seen the bolder with safety cones marking it in the parking lot where it is shown ending up in the video, that he lives in that area, and other interesting facts, none of which contribute to the determination of whether the video was or was not AI generated.

I went to the source of the video as far back as I could trace it, which is on the shopping center's website, https://www.facebook.com/mountainmilepf/reels/, and can only see that this one video is way out of character with every other video on the site in terms of messaging, formatting, and quality. The site has multiple administrators, and could have been placed there by any of them. Again, no proof it is or is not AI generated.

My position is that the visible evidence is reasonably clear that it is AI generated because of the rolling and bouncing of the boulder is inconsistent with a half ton or more boulder, there are no observable damages to the asphalt which should be very significant, and the movement of the Rivian seems very odd in its bounce (which might be explained by the active suspension exerting itself).

I believe that the boulder was originally set inside a curbing area that separates the entrance drive from the parking spaces, and I expect that is where the boulder originally was placed. I have no idea how the boulder was moved, but I do not believe the video is the real story. Just a guess, but the AI, or just the poor quality of the video is hiding other clues as to what caused the displacement of the boulder.

I didn't go very far back, but I only saw one other video of that boulder. And I got a big laugh out of watching the Tesla Model Y hit the boulder and have a very different outcome to the R1S (AI generated or not).

 

[Time2Roll]

Bolder seemed to bounce more than I would expect also.
Almost like a foam or fiberglass prop made to look like a stone. Landscapers use these to save money.
Or maybe it is real.

If I was local I would be over kicking a few rocks to see what gives.
